How to Handle mouse over events for Tool Bar Items in RCP

I have created a tool bar with few Tool bar items in my Application.
Menu:
<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="toolbar:main">
<command
commandId="com.test.myapp.ui.commands.TestCommand"
style="push"
tooltip="My Tool Items 1">
</command>
Command configuration:
<extension point="org.eclipse.ui.commands">
<command
defaultHandler="com.test.myapp.ui.commands.TestCommand"
helpContextId="test"
id="com.test.myapp.ui.commands.TestCommand"
name="Open Test View">
</command>
Below is my TestCommand class.
public class TestCommand extends AbstractHandler{
//Overridden the execute method here....
}
So now if I click on my Tool bar this will execute my Command class. I would like to know how can I add mouse listener to this Tool bar item so that we can do some stuff when mouse over on the tool bar item (Ex:Mouse over to tool bar item, it generally shows tool tip, So now if I press some key it should open some other page for this. So to do that if I can get the control of this event I can add some stuff to it)

Android Development: Nested Context Menus?

Is it possible to have nested context menus? I am working on an app which needs to provide the users with various functionality, and after much thought I came to the conclusion that using a context menu would be quite advantageous (would allow me to clean up my screen by getting rid of a few spinners etc)
However I was wondering if its even possible to have a context menu pop up, and then on the item select present the user with even more choices.
Something along these lines:
Context Menu 1
-> Change Font Color (on select generate context menu 2)
->Red
->Green
-> Change Background Color (on select generate context menu 3)
->Red
->Green
Would something like this be possible?

What IDE are you using? Do you what to do this in xml or Java? If you are using eclipse you could just create a menu in your "menu" folder which contains an xml file and then use their "manager" to create a sub menu.
Here's an example menu named game_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/new_game"
android:icon="#drawable/ic_new_game"
android:title="#string/new_game"
android:showAsAction="ifRoom"/>
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
To create submenu you have to "nest <menu> elements"

pulldown command menu options

I've added a pulldown command to my toolbar
<command
commandId="my.uri.Options"
label="%Options.label"
icon="icons/properties.png"
style="pulldown">
</command>
that under a pull down menu have some toggle options.
I would like to get to those option by pushing the button as well, and not just the menu triangle. Is that possible? Or my approach is all wrong?

Perhaps you could use the onclick event handler, or the you could explore the addEventListener() to change the action for when the menu is clicked.

add the same menu contribution to two registered context menus(in different views)

I have two views in my application.there are treeviewer in both the views on which i want to add context menus.
I registered the context menues using
getsite().registerCOntextMenu(menu,treeviewer);
in both the views
Now i added the menu contribution in plugin.xml file as
<menuContribution
locationURI="popup:org.eclipse.ui.popup.any?before=editions">
<command
commandId="com.eclipse.command1"
label="action"
style="push">
</command>
</menuContribution>
but this menu is shown in only one of the context menu not in both.
so is there any way to add this menu to all the registered context menus or using the id for menu so that they can be identified.

If you are referring to a group in locationURI then this group has to be present in the menu.
In general:
Any pop-up menu which is registered with the workbench should also define a GroupMarker in the registered menu with id IWorkbenchActionConstants.MB_ADDITIONS[="additions"].
In your case, the group should be named "editions".

Order of mixed menu 'action' and 'command' menu items in Eclipse RCP

At the moment I have two menus in my RCP application:
File and Help.
The File menu is created via a command:
<extension point="org.eclipse.ui.menus">
<menuContribution allPopups="false"
locationURI="menu:org.eclipse.ui.main.menu">
<menu
id="fileMenu"
label="File"
mnemonic="F"
tooltip="Main Menu">
<command
commandId="myPlugin.bundle.menuCommands.Exit"
label="Exit"
mnemonic="E"
style="push"
tooltip="Exits MyPlugin">
</command>
</menu>
</menuContribution>
</extension>
<extension point="org.eclipse.ui.commands">
<command defaultHandler="myPlugin.bundle.commands.exit.ExitHandler"
id="myPlugin.bundle.menuCommands.Exit"
name="Exit">
</command>
</extension>
The Help menu (with only the About menu item) is created via the respective action in ApplicationActionBarAdvisor:
protected void makeActions(IWorkbenchWindow window) {
aboutAction = ActionFactory.ABOUT.create(window);
register(aboutAction);
}
protected void fillMenuBar(IMenuManager menuBar) {
MenuManager helpMenu = new MenuManager("&Help", "helpMenu");
helpMenu.add(aboutAction);
menuBar.add(helpMenu);
}
Now, the Help menu comes before the File menu in the menu bar. This is obviously not how it's supposed to be. How can I change the order of the menus?
Many thanks!

Ah, solved this by simply adding a MenuManager in the ApplicationActionBarAdvisor for the File menu:
MenuManager helpMenu = new MenuManager("&Help", "helpMenu");
MenuManager fileMenu = new MenuManager("&File", "fileMenu");
...
menuBar.add(fileMenu);
menuBar.add(helpMenu);
Can I hear you go "d'uh!"? Cos that's what I did ;).
UPDATE:
Is this really how it should be done though? That'd mean that for every new menu I create in the Extension Wizard, I'll have to add a new line to ApplicationActionBarAdvisor...
Perhaps you could share your thoughts on this, or whether it's just an avoidable hack.
Thanks!
