The NSTableView has a feature, called Type Selection, by which the user can type the first letters of a listed item and the view automatically selects the first hit and scrolls to it.
I like to have a similar functionality in a NSCollectionView, where I list images by name.
Before I start writing such code by myself, I wonder if there is an API that can help me with this.
I am especially worred about getting the timing right, as I want to have it use the same timing as the NSTableView does. I imagine that it even changes depending on the user's System Preferences for typing. Also, the NSTableView will select other items with the same typed prefix if waiting long enough. All this can get quite complicated if I want to get it right. I don't want to miss anything.

I'm working on redesigning a web interface to provide the same functionality it has currently but with easier use via good UX design. Currently, here is what the design looks like:
I'm less worried about the tofu look and feel, that can come later, I want to nail the UX functionality first. The idea here in this tab is the user can select the items via a checkbox and perform the actions in the "I Want To" drop down (which opens different modal dialogs depending on the action). The 3 dot ellipsis on the right of the items in the list allow the user to perform the same actions via another drop down control, with the idea that they use the top drop down to perform the actions on multiple items, the ellipsis three dot menu for one item.
The obnoxious part of this control is that the list could contain hundreds of items, and the check box takes too much precision to check quickly. The user would select which items they would like to perform the actions on sequentially, then have to scroll up to the top of the page to select the action. This could be 5 seconds of scrolling, which I find obnoxious. I want to develop a good UX pattern to provide the same functionality in less clicks, scrolling, and frustration.
My inital idea was to provide a floating action button. The user could then * somehow * (I haven't thought of an idea yet, at minimum at least a bigger check box) select multiple items then pick what they want to do via the floating action button which is always within the bounds of the screen instead of the horrible scroll back to the top (I don't think a "scroll to top" button is a good solution for this either).
So I need some recommendations on a UX pattern or some general suggestions on how to make this process less frustrating for users. I'm a fan of material design right now, but I'm open to any suggestions, material design guides don't seem to have any paradigms for something like this.
I think the UX steps are in a good track: first select them, then set the action.
Instead of it being only a checkbox to click, the whole top part of each line could be clickable to select the item. This would make it much easier for the user, and less frustrating not being able to hit the checkbox.
Fixing the header on top would be usefull for adding a "Select/Unselect all" option and having the actions always available. Adding a searchbox to filter could be as well a good option if you are thinking of long lists. Combining the search box and the "Select all" option should help the user in their tasks.
If that is the most important action to be done in that screen, making the "What to do" button stand out a bit more would be a good idea to differenciate the primary from the secondary options for the user to do.
I see two simple things you can do to make this more usable with very little effort.
Remove the checkbox and make the entire row tappable, highlighting those selected. Each row would essentially become the checkbox's label, and the checkbox itself would be hidden from view.
Fix the header to the top of the browser window when the user scrolls down.
I've added some code as found here Big problems with MFC/WinAPI to colour tab titles the same as the reset of the dialog, which works, but unfortunately all the tabs end up with the same name. This doesn't surprise me all that much as GetCurSel() is used to grab the text to use, and only one tab can currently be selected, but I'm struggling to see how you access the correct tab index from OnDrawItem().
I've googled and had a look on MSDN but don't see how anything passed to OnDrawItem lets you know which tab is currently being drawn, rather all the examples I've seen assume you're only interested in the one currently selected. All I want to do is something along the lines of GetWindowText() on the child window and redraw with that. I'm also unsure of the parent/child/sibling relationship between the sheet, tab control and page - it depends who you listen to.
I should probably add that I'm also unsure why all the tabs are redrawn when I select one. I don't know if this is normal or something specific to this implementation (that's something I'm looking at, but like seemingly everything else in this code base it's multiply inherited several times over ...).
Cheers for any help.
Not to worry, I now realise lpDrawItemStruct->itemID holds the tab index so I can get a handle to the tab using that.
I have an NSTableView in which I need to be able to intercept keyboard events within an editable cell and replace the cell with strings. For example, press "a" and have the "a" intercepted and the value "Alpha" assigned when the table reloads. The actual situation is a bit more complex in that I'm also handling HID devices, but that's a whole other story. Suffice it to say, I just want to be able to go into edit mode and stop the keyboard-generated values from being displayed.
The latter part of this (displaying "Alpha") is easy, but I can't figure out the first part of the problem. If I subclass the table and make it first responder, I can receive the keyDown: event, but once the user double-clicks on a cell and starts typing, this goes silent.
Since none of the other NSTableView components (NSCell, NSTextFieldCell, etc) derive from NSResponder, I'm assuming there is an NSTextField buried in there somewhere.
So, what's the best way to filter text once the user goes into cell edit mode?
As always happens: after working on this for eight hours, reading all the docs five times, and then resorting to the net, I find the answer five minutes later:
- (BOOL)textShouldBeginEditing:(NSText *)textObject.
Sorry to consume bandwidth.
I am designing the (G)UI of a program, and have stumbled across a problem; The program will convert a number into different units, and the layout of a unit been converted to is:
[Unit name (when clicked gives information)]
[Special status, if any]
[Output in textfield that can also be used for input (to convert to other units)]
I want the user to be able to copy an outputnumber onto the clipboard, without having to mess around with highlighting and finding the right buttons to press. So, I thought I'd make a button after the text-output field, saying something like "C" or "Copy".
But I was reading on joelonsoftware.com yesterday, and discovered that users seem to be cursorclumsy. So what should I do?
I've thought about a number of different options:
Click on textfield to copy to clipboard - BUT: I want to use it for input as well
Pressing a numeral on the keyboard to copy the respective one - BUT: There will probably be more than 10, and I need them for new input
Bigger Copy button, like on that actually says "Copy" - Hmm, would this work? I know that I like to use the keyboard when I can, so a solution involving it would be nice.
Each unit will have its own space, where everything (name, textfield etc.) fits in. What if it would copy to clipboard when clicked anywhere in that space except for on the name or textfield. - BUT: What if you miss, meaning to click below one textfield, and clicking above another?
But what about highlighting the unit's space as I went along? - Could still mean trouble...
What do you think? I think I just might opt for #3 - Bigger copy-button..
There's nothing wrong with a Copy button after every field if you feel that it's going to be a very common operation.
Two suggestions, however:
In terms of look and feel, make sure that the button is clearly associated with the field. For a text field, the best way to do this is to put the Copy button inside the text field (on the right side - but be prepared to handle RTL languages by switching its position as needed!).
To avoid making it overly big, don't use any text, but rather use the stock Windows icon for Copy (like this one: ), and put the text into its tooltip. If you do that, you may also get rid of button border entirely, further reducing its size, though you'd still want some visual hover indicator to make it clear that it's an active UI element. In fact, you might want to specifically copy Vista/Win7 Explorer (also seen in IE7/8) UI for location field and the Reload icon in it.
I think the solution #3 is the best in your list, but I would like to see a sketch of your GUI.
What ever you do, it is important to use the OS standard keyboard and mouse event bindings and preferable look-and-feel too otherwise users get confused.
For sheer speed, the keyboard is the way to go. How about letters A-Z to copy the text boxes instead? Skip “E” to allow scientific notation to be inputted. Potential speed is high, but learnability is low. I’d expect users will have a hard time figuring out this UI even with explanatory text on the page/window, and if users have to read explanatory text, then the time that takes will likely negate the time savings of the UI, unless the user is using the app all the time (Joel also writes correctly that users hate to read).
For an app that will be used only occasionally, the big button is a better choice, the bigger the better, as predicted by Fitts’s Law. And absolutely label it “Copy,” not “C” and not an icon, to maximize learnability. Your other ideas have learnability and tolerance issues without the speed of the keyboard.
That said, I think you’re taking what Joel says too far. Certainly you want to eliminate unnecessary clicks, but the typical design for this type of app would require one click on the text box (which should by default highlight the whole value) followed by one click on a Copy menu item –or better, Alt-C or Ctrl-C from the keyboard. It’s hard for me to imagine a task where saving one click or a couple keyboard presses would be worth the clutter of a bank of Copy buttons beside your text boxes. Are you also going to have buttons for Paste and Clear? At some point the clutter will slow your users down more than the extra click.
How often are users going to be copying? If it’s really dozens of times per session, then you should re-think the whole design approach because any copying and pasting of one number at a time is going to get tedious. Maybe you should support batch processing, taking multiple numbers at once and outputting results in a form already suitable for the expected use. Maybe have it work within other apps like the way Enso does: user highlights a number in any document or text field of any app, commands Convert - Feet - Meters and it’s changed in the document or field.
If you accidentally click on the wrong area, you could just click on the right area after that. If your issue lies in the user not knowing when they click on the wrong area, just highlight the last-clicked area.
Is there a problem with copying whatever is in the textfield when they click on it? So what if it's being used for input? They're just going to copy the value they need after they type values in.
You could also have a ctrl-click or shift-click in the text box be a copy.
Most people know how to copy text on their own computer. Perhaps the best solution is to just auto-highlight all the text in a textbox when it gets focus so they can just ctrl-c to copy or start typing to begin input.
Drop-down lists, menus and combo boxes are all very common user interface elements. Users are accustomed to seeing these elements in native applications and sometimes web apps, but there are a few problems with them.
You have to aim the mouse. Some menus collapse when you mouse out, and some have submenus that you have to aim at to expand.
You can't see the options without aiming the mouse first.
These are the main things that trouble me, maybe other people notice other issues as well. I normally don't use drop-down menus at all if I can help it.
The problem is that I sometimes want to present a long list of options in limited space. Issue 2 is a sacrifice I'm willing to make, but I'm wanting to know if anyone has any tricks to make these drop menus easier to use. Maybe someone has invented a new style of list control.
I'm sure that if these types of controls annoy me, then they annoy users of my site more.
Hmm..one more thing which annoys me about the dropdown list is the inability to control their width as it expands with the text (or is their something which I am unaware of ?).
For an alternate, I think about a little popup which initially displays a list of available options in form of Alphabetic index and when the user clicks on an alphabet link, it displays the relevant options to select from. This will reduce the options to select from.
On the same terms, we can use ajax to build the options on the fly as user types in.
You could try something like Mac OS/X has for its taskbar, similar to the selection bar in YouTube. I think the common term is a bubble bar where small images animate larger as the mouse rolls over them, but shrink back down to such a size that all items are visible when the mouse is not over the control.
#Nrj
width='20px' will keep the collapsed drop down at a width of 20px. Problem is, Inernet Explorer shows the expanded item with this width also, while all other browsers i met so far will show you the full menu.
