Commands and Toolbar and Toggle style buttons? [message #336423]

Hi,

I am trying to do a very simple thing: I want to add
a simple button to the windows menu and the tool bar
and it should be a toggle button. I used the "Hello world
Command" template.

I have the following problems:

1. if I add it to the toolbar as in the with
locationURI as:
toolbar:org.eclipse.ui.main.toolbar?after=additions
the button appears but in the "Customize perspective"
the tool bar has no group and I am too stupid to figure
out how to create a group :-(

2. How do I update the toggle state of the tool bar command
and the menu command? (they should somehow listen to the
state of my Handler). I am sure there is somewhere some
magic, but I was unable to figure it out...

So, I thought I'd better ask the experts:

The "Hello World" Command template, is what its meant to be - the
starting point to understand the commands. It adds a command, a handler,
a binding and two UI contributions (menu and toolbar).

If you really wanted to learn beyond a "Hello World" example, I would
suggest you to get into the following links:

http://wiki.eclipse.org/Platform_Command_Framework
http://wiki.eclipse.org/Menu_Contributions
http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclips e.platform.doc.isv/guide/workbench.htm

http://blog.eclipse-tips.com/search/label/Commands

Is there something more can be done to simplfy the learning?

Prakash,

Great links! But I still cannot figure out how
the heck I create a group so it appears in the
customize perspective as something that I can select
(with a name).

Those groups each represent one toolbar in the coolbar, but the labels
in the CustomizePerspectiveDialog are kinda hacked in. Basically, they
currently come from
org.eclipse.ui.internal.WorkbenchWindow.getToolbarLabel(Stri ng). File
and Navigate are hard code :-) and everything else is looked up from the
actionSet registry. sigh, I can't believe this stuff.

So for example, if you create a new toolbar using something like:
<menuContribution locationURI="toolbar:org.eclipse.ui.main.toolbar">
<toolbar id="com.example.myToolbar">
<command commandId="org.eclipse.ui.help.aboutAction"/>
</toolbar>
</menuContribution>

Then com.example.myToolbar will be sent to that method.

But it implies a workaround would be to create an empty actionSet with
an ID matching your toolbar and the appropriate label.

Were you able to find the toggle update part? There should have been an
example off of the http://wiki.eclipse.org/Menu_Contributions page, it
basically involves using IElementUpdater on the handler.
