Are combo boxes supported in action sets now? 
I cant find anything else about that. Is this feature implemented? and if not
will it ever be impelemented?

Comment 2 Douglas Pollock 2004-07-14 10:41:27 EDT

No, they are not implemented. 

Comment 3 Ed Burnette 2005-10-19 09:12:00 EDT

I was trying to do an Eclipse version of
http://platform.netbeans.org/tutorials/nbm-google.html but ran into one little
problem: I couldn't find a way to override the way the visual control for the
action was created. In the NB example, they play a little trick that they define
an action as a button and then override the method that actually creates the
control to use a composite instead. I didn't see the equivalent trick on
Eclipse, nor did the Action class allow anything but Button, CheckBox, Radio,
and DropDown.

This example shows that a Coolbar can have a combo box:
http://www.java2s.com/ExampleCode/SWT-JFace-Eclipse/CoolBarTest.htm
It does it like so:
    CoolItem item2 = new CoolItem(coolbar, SWT.NONE);
    item2.setControl(createCombo(coolbar));

SWT snippet 58 does something similar with ToolBar:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet58.java?rev=HEAD&content-type=text/vnd.viewcvs-markup
It does it by creating a separator and then resetting the widget to be the Combo
control:
	ToolBar bar = new ToolBar (shell, SWT.BORDER);
	ToolItem sep = new ToolItem (bar, SWT.SEPARATOR);
	Combo combo = new Combo (bar, SWT.READ_ONLY);
	combo.pack ();
	sep.setWidth (combo.getSize ().x);
	sep.setControl (combo);

But both of these methods are only useful for RCP apps where I control the
CoolBar/ToolBar creation. I need to contribute a CoolBar/Toolbar item in the
IDE, which means I need it to be an Action.

I also want to add controls (images, text, buttons, combos) to the IDE status
bar; would that be a different request or can actions go down there?

See also bug 26797 (combo contribution from editors).

Comment 5 Douglas Pollock 2005-10-19 10:35:10 EDT

Ed: I would strongly encourage you to look at the contributions proposal 
(http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform-ui-home/R3_1/contributions-proposal/requestForComments.html).  
In particular, you should look at the <widget> element in org.eclipse.ui.menus 
extension point, and the IWidget interface.

combo boxes can now be added to toolbars using the menu contribution mechanism.

So how come all the interesting tags (such as group, widget, etc) are all marked as deprecated in org.eclipse.ui.menus extension point documentation?

They aren't used.  The menu contribution mechanism is more general than what was envisioned in 3.2.

Check out the org.eclipse.ui.examples.contribution plugin as outlined in http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/workbench_cmd.htm for an example.
