I need to implement a threaded view of sorts in an old VB6 app. It should look similar to this:
So, it's like a TreeView of sorts but there are buttons on the right (for each row) that could be pressed. The view does not need to collapse - it always stays in the expanded mode. The users should be able to respond to each node (via the comment button on the far right). And, of course, users should be able to scroll through the entries.
What are some of the ways I could implement this? I am open to 3rd party controls, paid or not.
VSFlexGrid has an outline mode. You can set the indent per row via the RowOutlineLevel property. It supports word wrap, images, etc within its cells/columns so you should be able to get pretty close to what you want. It also supports owner-drawn which lets you fully customize the cell painting (for example, to get those rounded corners).
I'm sure there are other controls out there as well...

I am using SWT tables in my project and there are few columns which are having longer strings which are not completely visible by default (for ex. path to a file location). Though I have tooltip to show the content and using mouse we can increase the column width to see the complete value.
Is there a way to do it with only keyboard usage?
Note: This question is more related to accessibility.
The following answer is based on my experience under windows. It can be different for other OS.
I'm afraid that there's no keyboard-only default way to adjust the size or reorder the column in a table, tree view or list view.
This is true not only with SWT but also with all other frameworks based on native win32 such as wxWidgets.
You must provide a keyboard-only way to resize and reorder columns yourself. here are a few ideas implemented by some applications:
Provide an option somewhere in the application that opens a dialog box with a checkbox list of the different columns. Ctrl+Up/Down to swap two items. Check/uncheck an item with spacebar to make the column visible or invisible.
Make the headers focusable. Use Shift+Left/Right to resize, Ctrl+Left/Right to swap two columns. Application key / Shift+10 opens a context menu where you can check/uncheck columns to show/hide and an option to open the column selection dialog box.
Some screen readers allow to do it by simulating mouse operation in some way. For example, use Jaws cursor, click lock on a header, release lock on the header to swap with.
But it's quite complicated, not always reliable, and thus very rarely actually used.
This is a very good question. I would be happy to give 100 rep to someone giving an answer being for windows and:
generic, working by default, everywhere or in most cases
Independant from screen readers (Jaws, NVDA, etc.) and techniques that simulates the mouse with keyboard (mouse keys)
Unfortunately, I don't think it exists.
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'm trying to have a feature to allow users choose two different methods of cost calculation: either they can enter a yearly cost breakdown on a datasheet (2010: $10,000, 2011: $12,000, etc) or they can enter a flat yearly cost multiplied by the number of years they select.
If I were developing another kind of web application, I'd have radio buttons to select two different options. One option would display the datasheet, and the other option would display two text fields to enter values into. However, I understand that you can't have radio buttons in Access 2010 web databases. Also, is it possible to make elements appear and disappear based on a combo box selection?
If not, perhaps I could have two different combo box options: "enter yearly cost breakdown"
or "enter flat yearly cost," which open the correct respective forms as pop-ups.
So, 1) can I have Ajax-like appearing and disappearing elements as triggered by a combo box (or ideally, radio buttons), and 2) if not, can anyone think of another clever way of doing it?
Sure, you get a nice effect by using a tab control. You can place controls and even a sub form on that tab control.
So, you build a screen like this:
Then, simple set the visible property of the second tab = No. This will hide the tab (don't change this until you built the page since it will hide it! (use property sheet to hide/un-hide during development).
Now, add some code to the after update event of the list box. Like this:
In the above, I have named the tabs PYear and PFlat.
The result is this (this is a animated gif I inserted):
Of course, you really probably could just dump the whole "list box" selection, and use a screen like this with the tabs (tabs are good UI, and users tend to grasp them quick):
So, you can hide a "set" of controls, and it really far less work and hassle then writing a bunch of JaveScript anyway. As noted, the "set" of controls you drop into each of the tabs can be sub forms, and also that of continues forms. So, the "hiding" as a set does work well in this case. I did have some format issues and found that I had to "start out" with the 2nd tab dispaled first (the first one being hidden). As noted, the listbox selecting is nice, but one could likly just go with using tabs in the first place.

I'm writing an internal-tools webapp; one of the central pages in this tool has a whole bunch of related commands the user can execute by clicking one of a number of buttons on the page, like this:
toolbar http://img709.imageshack.us/img709/1928/commands.png
Ideally, all of the buttons would fit on one line. Ordinarily I'd do this by changing each widget from a button with a (sometimes long) text label to a simple, compact icon - e.g.
button labelled "Save" http://img337.imageshack.us/img337/773/saver.png
could be replaced by a familiar disk icon:
Unfortunately, I don't think I can do this for every button on this particular page. Some of the command buttons just don't have good visual analogs - "VDS List". Or, if I needed to add another button in the future for some other kind of list, I'd need two icons that both communicate "list-ness" and which list. So, I'm still considering this option, but I don't love it.
So it's come time for me to add yet another button to this section (don't you love internal tools?). There's not enough room on that single line to fit the new button. Aside from the icon solution I already mentioned, what would be a good* way to simplify/declutter/reduce or otherwise improve this UI?
*As per Jakob Nielsen's article, I'd like to think that a dropdown menu is not the solution.
Edit: I'm not looking for input about the icon idea. I'm looking for other solutions. Sorry my example disk icon was a small one; it was just an example. I'm showing a bigger one now to hopefully be more clear.
I would add a More Link Like Google does.
See the Top Bar of Google with WeB Images Map More >>
To this more >> drop down you can add logic to add button less frequently used by user or something like that.
If you read Jef (and Aza) Raskin, you'll probably realize that icons are also not a good solution – both were pretty vocal in their dislike for them (with very few notable exceptions). For a start they're even harder to hit than tiny buttons, then their symbols can be confusing, culture-dependent and misleading. We're already good at reading text, parsing and interpreting icons is often slower.
In any case, that button bar looks like it accommodates pretty much anyone and their dog who might be using that product. You might have had some specific scenarios in mind when creating it that should be easy to do and are important. Most likely not all buttons are needed at once for such a task to complete.
Another thing is that maybe not all buttons are even useful at any single state of the application. Can you maybe branch into different sets of buttons, depending on the state. That's only possible however, if each state has clearly defined what actions can be taken. If all buttons are equally pressable regardless of state this won't do anything.
Grouping commands according to related functionality might also be an option. This doesn't have to be done with menu-like idioms, you can also put them into containers with different background color or even color the buttons themselves (just keep in mind color blindness, though). Depending on how related those individual functions are this can be a good way of speeding up interaction. It might requier some training for users to know what the colors refer to but for an in-house tool that's only used by people you know (instead of by arbitrary random ones [which is a problem Microsoft faces quite prominently]) this should pose not much of a problem.
What if you use icons and text?
For the commonly understood commands - use just an icon (like the save)
For the uncommon commands use an Icon + the text.
If you put a border around the button as a whole it should tie the icons / text together nicely and show it's still a button. You could also do some hover effects.
Since you can't do a dropdown menu (or similar techniques like clicking a button to generate a secondary menu). The best I can think of is what Prescott did or showing an area of buttons that are grouped in such a way to make it easy for the user to know which section their button should be in.
I would start by changing some of the longer labels. At a minimum, "Application Loading" could be abbreviated "App Loading." What's another (shorter) way to say "Quick File Transfer"?
You could also group the buttons into tabs (i.e. make it a ribbon). That might work particularly well if different classes of users tend to use different, non-overlapping sets of buttons.
Numerous options:
Group and labeling. Any time you have more than eight commands, you should divide the menu items into semantic groups of about four to help the user scan for the command they want. Labeling the groups also helps the scan and can make the menu more compact. For example, Instead of VDS Ping and VDS List, Have a group labeled “VDS” with “Ping” and “List” menu items. You’ve one less word to fit in (two if you put the label above it’s associated menu items when using a horizontal orientation).
Pulldown menus. Nielsen is correct about avoiding the use of a dropdown menu for making commands. However, he’s clearly in favor of pulldown menus which look and behave like a menubar in a thick client app (Nielsen calls them “command” and “navigation” menus). I think you’ll find that there are several Javascript pulldown menus out there now, unlike back in 2000 when Nielsen wrote his post. You can fit 100s of commands in a menubar.
Sidebar menu. Arraying the menu items vertically and you should be able to fit 20 or more commands and you won’t have to shorten any command names to something user might not understand. If that’s not enough, consider a “menu bank” than combines the benefits of sidebar menu with the capacity of a pulldown menu.
Ribbon. If your commands fit into discrete tasks, where the user tends to stick to one task for a while, you can arrange the buttons on a tab control, with one sheet per task.
Command Overloading. Represent your data objects as selectable entities in your window and change your commands into more general operations, like Drill-down, Create, Copy, Move, Delete, and Link, that can be applied to various different classes of objects, thereby reducing your total number of commands. The user can select one or more data objects then select the desired command to act on them.
Work Area Attributes. Some of your commands may not be commands by settings or attributes. Remove them from the menu and represent them as data objects in the work area of the page (or another page, if they are rarely used) using controls like radio buttons, dropdown lists, and check boxes. This has the added benefit clearly showing the user the current setting as well as providing a means to change it.
Variants. For an internal app, you probably have formal roles and responsibilities that vary by work position. Include the user’s position in your model, and dynamically hide commands (and other controls and pages) that aren't relevant to that position.
What about a combobox and a Confirm button?
Or a simple dropdown menu?
Add a "Tools" or "Actions" menu bar, and stick rightmost 4 commands (or more) into the menu.
Would it be possible to implement a "most used" or "preferred" set of buttons (preferably for the user, but globally if necessary) and button to take you to the rest of the items if you need one of those?
You could group them (like the two 'vds' buttons) behind a single button that, when clicked pops a context menu with the individual icons.
It truly seems like what you're developing is a administration console which happens to present its UI through a web page, rather than something which I'd quantify as a web app. As such, especially given your statement that this is an internal use application, Jakob Nielson's advice regarding <select> tags being poor design need not apply.
For this particular set of assumptions, I think the better option is to imitate a system menu setup using one of the many CSS-based menuing designs possible.
Icons are terrible from a user experience stand point. A picture of a Floppy Disk doesn't un-equivocally mean SAVE. It means something to do with a Floppy Disk. A Floppy really, its 2010, SAVE on a web app means save to the server, how does a Floppy Disk even compute?
Here is an application that has had the same extremely usable interface for 10 years! And hardly any images for buttons, and it is one of the most productive applications in its category.
You know what ICONS stand for I ncomprehesible C ryptic O bfucsated N onsense S ymbol!
Also how do you internationalize an icon?
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.
