Readymade Cocoa Spotlight UI Components - cocoa

I'm new to developing on the Mac and am looking to implement an interface similar to Spotlight's - the main part which seems to be an expanding table/grid view.
I was wondering if there is a component Apple provides for creating something like this or is available open source else where.
Of course if not I'll just try and work something out myself but it's always worth checking!
Thanks for your help in advance.

New Answer (December, 2015)
These days I'd go with a vertical stack view ( NSStackView ).
You can use its hiding priorities to guarantee the number of results you show will fit (it'll hide those it can't). Note, it doesn't reuse views like a table view reuses cell views, so it's only appropriate for a limited number of "results" in your case, especially since it doesn't make sense to add a bunch of subviews that'll never appear. I'd go so far as to say outright you shouldn't use it for lists of things you intend to scroll (in this case, go with a table view).
The priority setting can be used to make sure your assumption of what should be "enough" results doesn't cause ugly layout issues by letting the stack view "sacrifice" the last few.
You can even emulate Spotlight's "Spotlight Preferences" entry (or a "show all" option) by adding it last and setting its priority to required (1000) so it always stays put even if result entries above it are hidden due to lack of space.
Lately all my UI designs for 10.11 (and beyond) have been making heavy use of them. I keep finding new ways to simplify my layouts with them. Given how lightweight they are, they should be your go-to solution first unless you need something more complex (Apple engineers stated in WWDC videos they're intended to be used in this way).
Old 2011 Answer
This is private Apple API. I don't know of any open-source initiatives that mimic it off-hand.
Were I trying to do it, I might use an NSTableView with no enclosing scroll view, no headers, two columns, right-justified lighter-colored text in the left column, the easily-googled image/text cell in the right column, with vertical grid lines turned on. The container view would observe the table view for frame changes and resize/reposition accordingly.
Adding: It might be a good idea also to see if the right/left justified text (or even the position of the columns) is different in languages with different sweep paths. Example: Arabic and Hebrew are read right-to-left. Better to adapt than to say "who cares" (he says flippantly while knowing full well his own apps have problems with this sort of thing :-)). You can test this by making sure such languages are installed on your computer, then switching between them and testing out Spotlight. Changing languages shouldn't pose an issue since the language switching UI doesn't rely on reading a foreign language. :-)

Domino on mac client - weird doc behavior

I support an old (late 90s) Domino DB that has a growing number of Mac users. In some docs, layout regions become grayed out once you click anywhere in the doc even though it's still editable, i.e. if the cursor was in a text field and you type something blindly and save it, it will be there when you reopen the doc. It doesn't happen in all docs and I have found no pattern.
Any Domino designers seen any behavior like this? I don't this there is anything too weird in the code; onBlur or onChange used in some cases - that sort of thing. Nothing too complicated really. Thanks!
Layout regions are a nightmare to maintain: there can be objects with differing hide-when formulas stacked on top of each other that might be causing this. I suggest making a copy you can work in without worry: inspect each object fully (keeping notes) then delete. Keep drilling down until you hopefully hit an object that matches your grey-out. If you don't find one, then it could be a bug as posted by Richard Schwartz. As Richard and D.Bugger suggest, perhaps it's time to rebuild the functionality without using a layout region: layout regions never worked with a web browser.

What's the overhead of TPanel over TBevel

I'm working on a project where they essentially used TPanel for the only purpose of displaying a bevel (And maybe the design time convenience Panel have over Bevels).
Ok, I know TPanel is heavier than TBevel. Amongs other things, each TPanel create a user objects, which is a limited resource.
What I would like to know, beyond user objects, what's the overhead of TPanel? Is it next to non-existent (Especially on modern day machines).
If you were working on such a system, would you suggest :
Going back and changing all TPanel to TBevel.
Say "Ok it was bad. Lets not do it again in the future"
or
it's too small a concern and the design time convenience is well
worth it.
I wouldn't know if this design is intentional but, there's a slight navigational behavior difference when controls are grouped together in a window. If the focus is changed by arrow keys, after the one having the last tab order the first control will be focused (down/right), or vice-versa (up/left). IOW the focus will be wrapped in the parent. That's of course if any of the controls do not need the arrow keys.
Regarding the question, as it is already stated in the comments, apart from using up a count in an object pool, there're other resources associated with a window. It will also waste a few CPU cycles. There'll be one more level in the clipping chain or the messaging or keeping one more z-order list etc.. MSDN puts it as (I guess navigational aspect is being referred rather than visual partitioning):
For best performance, an application that needs to logically divide its main window should do so in the window procedure of the main window rather than by using child windows.
Nevertheless, as again already stated in the comments, most probably, no one will be able to tell the performance or resource difference caused by a few panels..
The correct answer is choice #3, so if that's the project's design approach, don't change it.

How can I enhance the aesthetics of an ugly windows form packed with too many (necessary) features?

One of the window dialog of a software I'm working on looks a bit like this : (original screen-shot copied from this coding horror post, other examples available on this SO question)
The thing is that none of the options can be removed (those who can have already been), and that they must all be visible at a glance (i.e. no tabs allowed) Edit : I've added a comment explaining why tabs are not an option in my specific project.
I've tried to use colors, to add icons, but it just added to the overall feeling that someone had just dropped controls randomly using Visual Studio Form designer during a summer internship.
How can I make this dialog more user-friendly less horrifying without deleting features ?
Edit :
The GUI example I took has a lot of obvious design flaws (see those answers 1 2), but even after fixing those (which I've done on the software I'm working on), the dialog still looks pretty ugly.
Below is another example (credit). Controls are (almost) lined up correctly, appropriate controls are used, etc, but the overall result still looks terrible :
(source: judahhimango.com)
Given the constraints I think you won't have many options.
A good starting point would be to equal the alignments and control distances to increase overall symmetry with the ultimate goal to reduce visual clutter.
Examples:
The group boxes "Special" and "Running options" should have equal height.
The distances between the four buttons "Save settings" and "Exit" should be equal.
All buttons should have the same height, if possible avoid word wrapping.
Use the same height for all single-line edit boxes.
The quota label and its text field should be at the same baseline.
The distance between a group box caption and its first control should be equal (compare "Running options" to "Retrieval options")
Increase the distance between the controls in general, i.e. make the form look less dense.
Content fixes:
Use the same captions/names for the same things. For example, you use "Append to logfile" but "Overwrite Logfile
Use the same character case, sometimes it's "Only the first one", "Every Single Word" and sometimes "it is Camel-cased". Decide on one scheme and use it consequently (Sentence case and Title case are the most common)
Don't try to be cool, "Go 2 background" doesn't look very professional.
Avoid controls with unreadable shortcuts or no content at all. It doesn't help if the user has to stop on every control and think: "What does this thing do?"
Some more radical/controversal changes:
Try making the group boxes more symmetric, possibly be re-positioning them and use the same height. If necessary use two columns of checkboxes, that would still look better than uneven group boxes.
Unless it's absolutly necessary, remove the horizontal scroll bars from the two multiline edit boxes
Get rid of the "Clear" buttons. For the list box on the buttom left you have to provide some other way to delete items, perhaps make this into a multine text box, too.
Try replacing the checkbox collection with a checkable list box or a property grid.
A rule of thumb:
Imagine the lines of the bounding box of each control lengthed until it reaches the form boundary. The less different lines reach the boundary, the better. (Because correctly aligned controls produce more incident (-> less unique visible) lines)
On the use of colors and icons:
Simply adding icons and colors doesn't solve the fundamental problems such forms have. They all suffer from being overloaded with controls and adding even more only worsens the problem, because they just add more visual noise, but don't provide any more visual cues.
The problem with your examples, and the reason that they look cluttered is that there's not enough spacing between the elements. You think you're saving space by making things smaller, and putting them closer together, but it's a false economy because your eyes have to work harder to differentiate elements from eachother. Think about writing a computer vision program that had to OCR those interfaces, and the challenges you'd have just figuring out which element was which, let alone what the type says.
Regardless of what your programmer efficiency instincts might say.. it's okay to put space between your elements, and hell, it's okay to even have large amounts of completely "wasted" space too.

think about what the line spacing is doing to your ability to distinguish words from eachother. What's it doing to the visual sense of clutteredness?
You can see from the type example that you don't have to give up much in terms of space efficiency to see massive gains in visual appearance.

thinking with type
other reccomendations:
stop stealing sheep
elements of typographic style
the design of everyday things
the humane interface
If you've already dealt with alignment and organizational aspects as much as you can, then your problem probably is the graphic design of the controls. Heavy 3-D controls in large numbers are detrimental to the aesthetics and usability of a window. Consider editing their properties to flatten and lighten the controls’ appearance, using something I call “compact presentation.” In addition to removing the ugliness and distraction of heavy borders and backgrounds, this also allows controls to be placed closer together, freeing white space for grouping them without resorting cluttering lines and frames.
It looks something like this (after also fixing alignment and redundancy along with a little re-arrangement of groups):
(source: zuschlogin.com)
If you're on WinForms, One trick I've found useful is to pack multiple-instance data in a DataGridView, and single-instance data in a PropertyGrid. Both these controls help you pack lots of information in very small space, and still give you full control over their visualization (you can add descriptions, tooltips, etc.)
The thing is that none of the options
can be removed (those who can have
already been), and that they must all
be visible at a glance (i.e. no tabs
allowed)
Sigh. I would argue that, because everything is visible at a glance, they practically become invisible in a sea of controls.
That being said, the ff (yes another list) are my suggestions:
To reduce clutter, make the overall form bigger, and all controls more widely spaced apart in all directions
Standardize the height of the controls, e.g., textboxes must all have same height, buttons all have same height, etc
Align labels with text boxes more consistently
Make the layout flow down instead: 1 column, with each group having the same width as all other groups
Set all group box names in bold to make them stand out
Put all those "wGetStart.bat" commands in a group of its own
If you really want to learn more about making it "flow", with or without getting rid of all this "visible" information, you might wanna get a copy of Steve Krug's Don't Make Me Think:
Because tabs are not allowed, you can create a more grid like layout.
Adding detachable panes for related options and commands can help the user to organise them, at least. If they can be minimised/unpinned when not needed, then they can also free up valuable screen estate and unclutter the UI. See VisualStudio itself for a nice implementation.
Here's my random selection of suggestions:
make it bigger, this allows a more structured grouping by reducing the space constraint on each group
add some structure by grouping options that the user might want to combine at the same time
add meaningful headers (might require the previous item). "special", "running options", "retrieval options" don't really convey any useful information.
make sure that only options that can be combines randomly are checkboxes (for example are "no info", "all info", "some info" really completely independent options? Same for "append to logfile", "overwrite logfile").
use appropriate controls (spinner for number entry, file selection dialog for files, radio buttons for mutually exclusive items, ...)
deactivate controls that make no sense with current configuration (for example custom directory text field).
move all actions to a single place
hide the scrollbars unless they are actually needed (i.e. reduce visual clutter)
be more consistent (why is it "running options" and "retrieval options" but not "special options"?)
One thing that you may have, but is obvious for the WGET example is the use of a main menu, e.g. File, Edit, Tools, Help. And also a button bar too?
First, define a hierarchy of control blocks. Even if everything must be visible, I think that some functions are more important than others. Also, make a clear separation between functions that apply to the domain (e.g., Start wGetStart.bat) and functions that apply to the software (e.g., Save settings).
Second, organize the layout according to this hierarchy: most essential to the top and to the left.
Third, let your design breathe. Space is fundamental for defining content.
Since no one has said this yet, I will: your window isn't really all that bad. Yes, it's ugly, and yes, I would be personally embarrassed to admit that I designed an interface that looks like that.
However, this window only produces a negative reaction the first few times you look at it. Once a user has used this form a couple of times, they will stop seeing it as a random collection of controls and instead start perceiving it as an interface that lets them see every piece of information that they require at a glance and that lets them do everything they need to do with a few mouse clicks.
It's a dialog for setting a bunch of options, and it's probably perfectly functional and not a big deal at all for your users. You could put a lot of work into some weird, fancy-schmantsy replacement UI that might impress the StackOverflow code-noscenti, but we don't pay your salary.
Now, the second window - that's a piece of crap.
Without knowing both the content your application and what it currently looks like, I can only guess at the problems you are facing, but here goes.
You say that this is being used by traders. While I have never dealt with that segment of the market I have often dealt with executives who need very specific information to run their businesses and the first cut of the application almost always looked like what you have displayed.
The original solution back in the day was to build a very light custom interface for each user of the application focusing on only the information relevant to that person. More recently the move has been toward making the interface customizable by the end user.
Chances are that none of your users are using all of the information presented to them. Each of them is using only a small subset. But each user is using a different subset. Try building the software so that each user can display only the information that they will be basing their decisions on.
Aside from other much-needed changed, adding a banner (displaying the company logo or something like that) seems to improve the overall appearance of the dialog.
I know it's a pure waste of space but it seems to improve the global feeling about the window.

Duplication - they might all have to be available instantly, but they could be available elsewhere as well. So you can have a keyboard accelerator, menu option, detachable panel, tabbed area ...
So this existing form could be the main, default interface (albeit improved with some of the other good design tips in other answers), but why not create an "expert" panel which can be a lot neater and try to work your users on to that, and away from this old "do everything" blotter.
I would really consider evaluating the usability goals of your project. Figure out what users want to do most frequently and most consistently with your application and default to that.
You should consider a wizard for this UI. Guide the user through a set of screens for the first use. And move many of these features as configurable options preferences.
Usability is not merely aesthetics IMHO. It is about making clear what the app is intending to do. I would refactor this app to provide shortcuts to common options patterns. If 90% of the time I am going to use a specific configuration of options why do I need to see every feature enumerated in the UI 100% of the time? It is just unnecessary clutter. Sensible defaults powerful configuration that is the goal. You don't have to sacrifice features, in a sense not making me think is a feature, perhaps the most important feature.
With respect to your specific app I would rework it with two basic screens a clean default screen and an advanced screen. Add the ability to create shortcuts to common configuration sets on the default screen. A simple button that maps to a specific configuration set and asks me for a url. And if the user needs to tweak an option present them with the advanced screen but treat it as preference configuration screen that saves the preference out to a shortcut button. If I want to use the configuration more than once let me save it as a custom bookmark or option on the defaults screen.
This is one of the things OS X does really well. There is a lot of power and customizability in OS X, "hidden features" if you will. But the OS defaults to sensible and straight forward options. Provide tools to the power users but don't clutter the system for the first time or casual user. This is not sacrificing functionality, it is effectively organizing functionality.
That is my first suggestion. But if absolutely don't want to hide options, I would make this a long scrollable vertical list organized in clear steps with explanation for each step:
Step 1: Provide URL ______________
Step 2: Configure Hosts _____________
Step 3: Configure Retrieval Options:
() option
() option
() option
() option
And so on...
At each step provide some context to the meaning of the configuration options.
The advantage to this is that you can clean up the UI aesthetically and provide useful configuration hints. I don't know what "Empty wGetStart.bat" means. I presume this empties a batch file of some sort. Provide me an explanation so that I know whether I want to click that button or not. And then let me hide explanations under a collapsible menu if I use the interface regularly.
My two cents.
This may not be appropriate, but...
Hide all the options in a stylesheet, much the way that all the paragraph formatting options are hidden in a word processor. Most of the time, the user just picks a named style. When the scary stuff is necessary, a click of an 'Advanced' button can grow the form to show all the options at a glance, to allow a few to be overridden, or to allow new named styles to be defined.
Obviously, a major advantage is that if there are a few particular configurations that are regularly used, it's trivial to switch between them and there's very little risk of accidentally setting one of the options wrong.
Another option - don't have all your options on display, use tabs or a wizard or whatever. Instead, have a text list of all options currently set (or all options in non-default states or whatever) to get the at-a-glance visibility.
These could be combined, so that your summary display says something like "like <style name>, except for ...", based on the style that's least different to the current options.
In a comment you say that a user "HAS to have all information available at once". Does that mean they have to see all the checkboxes and frames and scrollbars at once, or just the information?
For example, instead of having a multitude of checkboxes for option 1, option 2, option 3, etc, in the main GUI, only show the selected options and give the user a way to open a configuration window when they need to change something.
Instead of this:
+- Feature Set X - +
| |
| [x] option 1 |
| [x] option 2 |
| [ ] option 3 |
| [x] option 4 |
| |
+------------------+
show this:
feature set x: option 1, option 2, option 4 [configure...]
This lets the users see all the selected options without having to take up valuable real estate for all of the widgets necessary to change the values.
(apologies if the ascii art doesn't appear right -- it looks right in a fixed font :-\ )
An interesting article on this topic:
Managing UI Complexity by Brandon Walkin.
In the second example I would remove most of the arrows from the right hand side box. I would add the ability to click and drag to change the number(if your users are used to that I know several 3d packages that do it so it wouldn't be uncommon in relation to the example). You can change check boxes to buttons with backgrounds that change color or stay depressed when clicked as another option to reduce visual clutter.
In the right hand side box there are two or three separate functions mixed together that very well could get their own tab. When you are working with an object's color and texture you aren't going to be changing its size and view aspect ratio so having them right there means they are in the way. At the very list they need to be rearranged to be in some sort of logical order right now they are all over the place. Texture and color(things that effect color) should be together. Position rotation and view(things that effect shape\size) should be together.
It has already been said, but without seeing your application we can't give you a concrete answer on how to make your dialog less horrifying. If you can't post screenshots, then the best advice I can give is to hire a designer to help you work on the graphical end of your application; otherwise all you will get are general guidelines here.
Some things that might have not been discussed:
Think about the users of your applications and the systems that they run. I believe that most stock traders will have large dual monitor setups, so you can probably make your dialog larger and add space between your controls to make it look less cluttered. You should research your audience and see what they use.
Are you using the best controls for the job? In the first screenshot you posted I noticed a few controls that could be changed:
a. Under "Running Options" I see three checkbox options called All Info, No Info, Some Info. If only one can be selected at a time then maybe they could be changed into a drop down selection menu. Also under the same "Running Options" there is Append Logfile, Overwrite Logfile, which again you can convert to a drop down menu since you can select only one.
b. The two text fields where you can put in hosts, can probably be combined into one gridview with three columns. The first column is the host, the second is a checkbox for Accept, and the third is a checkbox for Reject.
By simply using different controls, we can still see everything we need but have less controls on the application.
Again, like I said above, witout seeing YOUR applications I can't really give you any specific suggestions.
Hope this helps.

User interface paradigms that need changing?

Often times convention is one of the most important design consideration for user interface. Usually the advice goes to do it like Microsoft does.
This is for three reasons:
If it ain't broke, don't fix it.
If your users expect to click on a floppy disk icon to save, don't change the icon (even though some of them may have never seen an actual floppy disk).
Users don't want to re-learn the interface (and hot keys, etc.) with each different application they use.
At the same time Emmerson said "*A foolish consistency is the hobgoblin of little minds.*" So when does maintaining a consistent user interface cross the line from a good idea to stagnated innovation?
Microsoft shook up the good old WIMP GUI with the introduction of the tool bar, and then again with the Ribbon control (which is the natural evolution of the tool bar, like it or not.) Now we are seeing ribbons everywhere.
So my question is, what are some user interface paradigms that are accepted and consistent across multiple applications, but have stayed past their prime and are starting to reek? Are there some important changes that would benefit from a grass roots push by developers to innovate and improve the user interface experience for our users?
One thought that came to mind for me is the modal pop-up dialog. You know the ones that say: "Are you sure you want to . . .. - [Yes] [No] [Cancel] [Maybe]" and its evil twin "Successfully completed what you wanted to do! [OK]." We are seeing a movement away from these with the "info panel" in browsers. I think they need to be adopted in windows application development as well.
If possible please list a solution for each stale UI item.
And please don't list clippy. We all know he was a bad idea.
NOTE: This is specifically Windows client user interface paradigms, but I am certainly open to drawing inspiration from the web, the Mac, etc.
You mentioned popup modal dialogs , and I'd argue that non-modal ones are just as bad. Any dialog box remove focus from the program, they could end up behind the program and make it hard to find it, they might not even appear on the same virtual screen.
I'd like to see an end to all dialog boxes. If you need to stop someone from using the UI because of some non-normal circumstance, then remove the relevant parts of the UI from the window, and replace it with what the dialog would contain. Bring back the UI once the problem has been handled.
Clicking things on touch interfaces
It's incredibly difficult to click on things on a touch interface, because you don't know when you have pressed the screen hard enough. And if you add an animation to the button you are clicking, you most likely wont see it, because your finger is in the way. Adding other reactions, like vibrating the phone or painting waves on the screen might work, but there is usually a delay which is too large, much larger than the tactile sense of a button being pressed. So until they invent a screen with buttons that can be pressed, all touch devices should move towards dragging user interfaces (DUIs) instead.
Counter intuitively it is easier to press an object on the screen, drag it, and then release it than it is to just press and release it. It's probably because you can see the object moving when you start dragging, and you can adjust the pressure while dragging it. Dragging also has a lot more options, because you now have a direction, not just a point that you clicked. You can do different things if the user drags the object in different directions. Speed might also be used, as well as the point where the user releases the object. The release point is the real strength of DUIs, because it is very easy to release something, even with pixel precession.
Some designs have started to use DUIs, like (here we go) the iPhone, palm pre and android phones. But only part of their design is DUI, the rest is clicking. One area they all have in common is the keyboard. Instead of clicking on a key the user presses any key, then drags their finger towards the key they really wanted to click. Unlocking these phones also uses dragging.
Other easily implemented DUI features would be things like mouse gestures, where dragging in different directions, or drawing different shapes does different things. There are also alternate keyboards being researched which puts a bigger emphasis on dragging. All buttons can be changed into switches, so have to drag them down a bit to click them. With a well designed graphics, this should be intuitive to the user as well.
The Apple Human Interface Guidelines are a good read on this topic. They discuss this from a very broad point of view and the guidelines apply to any platform, not only Mac.
The file system. I want to save a file.. >OOOPs I need to think of a file name first. Well.... how about ... blah.doc.
6 months later...
Where the %#*(%& * did I save that %()#*()*ing file?
The solution is build a versioning system into the application, or better, the OS. Make files findable by their content, with a search engine, instead of forcing the user to come up with a memorable name, when all they want is for their file to not get lost.
Eliminate the save step. Type something in to the application, and it's just there, and there's no risk of losing it by some misstep, like forgetting to save. If you want an older version, you can just pick a date and see what the document looked like back then.
To build on the search engine idea: It's a pain having to navigate some arbitrary tree structure to find your stuff. Searching is much easier. However, you might still want to have something like a "folder" to group multiple files together. Well, you can build a richer metadata system, and have a "category" or "project" field, and setup the search engine to show items by project, or by category. Or group by those, or whatever new UI discovery we make next.
This question is a bit too open-ended, IMHO.
However, my main approach when designing anything is:
Fits in to wherever it is. If it's a windows app, I copy MS as much as a possible
It's simple.
It provides options
Buttons have a nice description of what the result of clicking will be, as opposed to 'yes or 'no'
Harder to answer the rest of your post without spending hours typing out an arguably useless (and repeated) set of guidelines.
In my mind, the one thing that really stands out is that USERS need more and easier control over the application's user interface appearance and organization.
So many interfaces can not be modified by the user so that the most used/favorite functions can be grouped together. This ability would make your favorite software even easier for you to get things done.
Error messages need a "Just do it!" button.
Seriously, I really don't care about your stupid error message, just DO WHAT I TOLD YOU TO DO!!!
I think the entire Document model of the web needs to change. It's not a user interface, but it leads to many, many bad user interfaces.
The document model was a good idea to connect a bunch of documents, but now the web is also a collection of applications. Today, I think the Page/document model corrupts our thinking. We end up lumping things together that aren't related, modularizing our code wrong, and in the end confusing users with our monolithic control board type websites.
Find dialogs that sit over the widget in which you are doing the search are terrible. Loads of apps do that. The find bar in Firefox works much better.
Many applications have multiple panes within the UI - eg in Outlook there's the preview pane and the inbox pane (amongst others). In these applications typically cursor key presses apply to the currently focussed pane. But there's very poor hinting to show the user which pane has focus and there are seldom keyboard shortcuts to move the focus between panes.
The focussed pane should be highlighted somehow.
Something like alt+cursor keys should move the focus around.
Ctrl-Tab and Ctrl-Shift-Tab cycle left and right through tabs instead of MRU behavior, even though in most cases the same behavior is duplicated with Ctrl-PageUp and Ctrl-PageDown.
There are a lot but here's an idea for a couple of them:
Remove some clicks like in "add another" or "search item" and the like.
This is well done with interfaces like ajax which have autocompletes ( and auto search ) but is slowly being adopted for platform UI's ( and in some cases they were originated in platform UI's. )
This is how StackOverflow does it for some scenarios.
But of course, we all know that already don't we? No need for "Seach tag" or "Add another tag" buttons, they just happen
Dialogs as you described.
Guys at Humanized proposed Transparent messages which actually are used in their product Enso and some other places.
Mac uses them for notifications ( like in Growl ) use them very well, or Ubuntu new notification system.
alt text http://blogs.sun.com/plamere/resource/NowPlayingGrowl.png
Firefox replaces the traditional "Search" dialog box with a search bar at the bottom.
Although not everyone likes the placement for next/previous as in this screenshot
And even SO ( again ) :) replace the notification with the yellow bar.
Finally:
File managers
I really like ( sometimes ) the simplicity of regular file managers, but some times I would like to work faster/better with them.
If you compare IE 4 with IE 8 you can tell the advance ( even better compare IE 4 with Google Chrome )
But if you compare Windows 95 Explorer with Win XP they are almost the same!! ( Win Vista/7 is a step forward )
But I wonder: Why haven't file managers improved as much as webbrowsers?
That's one reason I like stuff like QuickSilver but it is just a step. Much work is needed to create something like a "Perfect program launcher" or (FileManager/DesktopSearcher etc as you wish )

Implementing "scrubby sliders" in Cocoa?

How would I go about implementing something along the lines of "scrubby sliders", like in Photoshop and quite a few other image-processing applications?
They are slightly hard to describe.. basically you have a regular numeric input-box, but you can click-and-hold the mouse button, and it functions like a slider (until you release). If you click in the box, you can select text, edit/paste/etc as usual.
The Photoshop docs describe it, and I put together a quick example video (an example of the sliders in Shake)
Another similar implementation would be the jog-wheel in Final Cut Pro, which functions similarly, without the numeric readout being underneath.
I can't seem to find any mention of implementing these, although there is probably alternative names for this. It is for a OS X 10.5 Cocoa application.
It is for a colour-grading application, where a user might need to make tiny adjustments (0.001, for example), to huge adjustments (say, -100 +100) on the same control. A regular slider isn't accurate enough over that range of value.
Copy-and-pasting values into the box would be a secondary concern to scrubbing the values, and the Photoshop/Shake setup really well. The unobviousness of the control is also of a low concern, as it's not a "regular desktop application"
I've encountered those. They suck, because they prevent the user from dragging to select the text of the number.
A better idea would be a miniature slider beneath the field that expands to a full-size slider when the user holds down the mouse button on it and collapses back to its miniature size when the user releases the mouse button. This way, the selection behavior is still available, but you also provide the slider—and in a more obvious way.
There's no built-in class in Cocoa for either one. You'll have to implement your own.
I doubt that this exists in Cocoa framework. As far as I remember it is not mentioned in the Apple Human Interface Guidelines.
You can develop one yourself by using a custom view and tracking mouse events (-mouseDown:, mouseUp:, -mouseDragged:).
