This is difficult to research, because all the keywords are quite generic...
A Thunderbird extension that I just wrote warrants changes in Thunderbird's main preferences dialog, because one particular setting collides with the extension's function and renders the latter useless if chosen/set.
I would like to do one or better both of these things:
1) Untick a checkbox and change the state of a radio button.
2) Altogether deactivate a checkbox or a radio button.
I found the following code snippet, which might do what I intend (at least for point 1) above):
var pref = Components.classes['#mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch);
pref.setIntPref("dom.max_script_run_time", 30);
If it does, I still have the problem of finding out the IDs of the preferences I want to change. The DOM-Inspector extension obviously does not work on the open preferences dialog window... so how do I know which preference to set?
And how do I overlay the preferences dialog in order to deactivate widgets? Is this at all possible? Or can I deactivate widgets programmatically (as soon as I have their ID?)

I have an Eclipse application that uses a ViewPart as a floating window with buttons/options for what is happening in the editor.
It looks similar to the floating tool windows in GIMP.
Implementing ISaveablePart in the ViewPart provides a default dialog upon closing the ViewPart with everything I want: a Yes button for saving, a No button and a Cancel button.
However, I would like to customize that default dialog.
Is that possible? If so how?
I looked into ISaveablePart2, but I just end up with my own custom dialog PLUS the default. Is there a way to suppress the default dialog in ISaveablePart2? If so, that would also be a solution.
For clarity: I'm not married to either of these ideas. What I ultimately want is a custom dialog box to come up when someone closes the ViewPart to ask the user if they want to save the contents of the editor ---> with an option to cancel the closing of the ViewPart.
If you use ISaveablePart2 you should only get your own dialog as long as your promptToSaveOnClose method does not return ISaveablePart2.DEFAULT. So there should be no other dialog if you return ISaveablePart2.YES, ISaveablePart2.NO or ISaveablePart2.CANCEL.
The standard Save Prompt dialog is not customizable.
The code for this is org.eclipse.ui.internal.SaveableHelper.
I open a context menu programmatically. Now additionally I would like to highlight the first menu entry.
This highlighting happens when I move with the mouse over the context menu or press the arrow keys on the keyboard. I am interested how I can trigger this programmatically.
I know the API of MenuItem does not offer this feature out of the box. So I tried to fire some MouseEvents of the type MouseOver and MouseHover, but without any success.
Has anybody an idea how to implement this feature?
I am not sure if you can change menuitem highlight colors, I haven't seen any previous example before. Look at this though: Change eclipse menuitem color
If you want to simulate what the user does and if you happen to know the location of the menu item, you can use Display#setCursorLocation() to position the mouse pointer over the menu item.
Note however, that if and how a menu item is highlighted is platform specific.
You should not use this method other than for demonstration of test purposes. If your application needs to highlight or preselect an entry in a list of choices,
you should probably use another widget. If you more describe your use case, we may be able to find a suitable widget.
My GEF editor (extending GraphicalEditorWithFlyoutPalette) always opens the editor with the palette hidden on first start of the application / first opening of the editor (after a build for example).
As this will potentially bewilder users who'll need to go in search of the flyout icon first, I'd like to have the palette view shown whenever the editor is opened. The user can then choose to close it on his/her preferences.
How can I achieve this? The API doesn't seem to give any clues, or I'm unable to find them...
The state of the palette defines if it is open or closed. This state is accessible using the getPalettePreferences().setPaletteState() method that is accessible in the GraphicalEditorWithFlyoutPalette. To open the palette, you must set it to the FlyoutPaletteComposite.STATE_PINNED_OPEN, like this:
getPalettePreferences().setPaletteState(FlyoutPaletteComposite.STATE_PINNED_OPEN);
If you want to ALWAYS override the state so that the palette is always opened with the editor, you have to add the line to the constructor of your editor. If you only want to do this once, and then leave the state as it was last selected by the user... No idea how to do this :-(
I have a org.eclipse.swt.browser.Browser instance created in a composite. I would like to know when some content is pasted in the browser using the (platform specific) right click context menu and selecting the paste option.
In the menuDetected() of MenuDetectListener, I get a notification when the context menu is detected in the browser.
How can I know if the Paste option is selected from the context menu?

No you can't access the selected context menu item. There is no direct provision for that. At least not in eclipse 3.7. Although, you could try different combinations of events for determining the menu item. For example, in windows the internet explorer populates the status bar with 'inserts the clipboard...' when your mouse pointer hovers over the Paste menu item, you can capture this using StatusTextListener event.
Note: The hack is not an elegant solution, even if you get it working, there is still some possibility that it may break with new or older releases of SWT or in fact its behavior may vary with operating systems !!
We have a multi-tiered/hierarchical YUI menu activated via a YUI menu button. Everything in this menu works pretty well. If you mouseover a menu item with a submenu, the submenu appears as expected. You can select an item from this submenu just fine.
The problem, however, is that you can also click on the parent items of this menu which closes the entire menu. In fact, I want the opposite. I'd like a click of a parent menu item leave the top level menu open and open the submenu (i.e. I want a click to be identical to a mouseover event in terms of functionality).
Side note: This isn't an issue on a typical web browser (e.g. Firefox) where the click event doesn't matter because you can't have a click without a mouseover. This is an issue on the iPhone which doesn't have a mouseover event.
I've been playing with the autosubmenudisplay properties and keepopen properties, hoping I can just handle the parent item click events to do what I want but, so far, I've been unsuccessful. If I set autosubmenudisplay to false, I can't figure out how to get the submenus to display manually. The keepopen property doesn't seem to work rather I set it on the menu or submenus.
Is there a way to get the behavior I want so our iPhone users are happy?
Todd Kloots, author of the YUI Button and Menu widgets here. Took at look at your request. Unfortunately the current version YUI Button and Menu aren't designed to support the type of interaction you are looking to create. Feel free to file a feature request via SourceForge and I'll try to work on this for a future version of YUI.

It's not exactly what you asked for, but have you looked at iUI? You may be able to pick up some tricks from the implementation.
