Hi,
I am writing a plugin which includes a popup menu specific for a
graphical editor defined in another dependent plugin. I define the
menu like this:
<extension
point="org.eclipse.ui.popupMenus">
<objectContribution
objectClass="com.ibm.example.ObjectA"
id="com.ibm.myPlugin.AddMarkerAction">
<action
label="Add Marker to A"
class="com.ibm.myPlugins.actions.AddMarkerActionDelegate"
enablesFor="1"
id="com.ibm.myPlugins.actions.AddMarkerAction">
</action>
</objectContribution>
<-- ... more other menu , e.g., RemoveMarkerAction -->
</extension>
The menu is correctly popped whenever I choose an object of class
ObjectA in the graphical editor. My menu is added as MB_additions.
My AddATagAction is already implementing IObjectActionDelegate.
However, what I want is the menu be enabled and disabled depending on
some situations other than the ObjectA's attributes. For example, I
only want to add a marker if there is no marker of a certain marker type
already defined for ObjectA. I have to programatically check this
condition rather than specifying it in the plugin.xml. I currently do
this by overriding the selectionChanged() method in IActionDelegate to
call action.Enabled(true/false).
I find that the first time when I bring up the editor (which is not
implemented by me), all my menu would show up regardless. After I
choose my menu item, my plugin is loaded. Then from that time onwards,
the menu could be enabled or disabled programatically.
How could I fix the problem of all menu are showing without calling my
condition code when first brought up?
Thanks,
Grace

Hi Grace,
.. Don't make extension point of the eclipse popup menu in the plugin.xml
.. Set your context menu in your graphical editor.Please refer the =
following code:
protected void configureGraphicalViewer(){
...
viewer.setContextMenuProvider(getPopupMenuProvider());
...
}

Another option is to designate the plugin with the menu for early startup
instead of being loaded on-demand:
<extension point="org.eclipse.ui.startup" />
Since the plugin will be started, the action delegate will be instantiated
and selectionChanged() will be called every time.
I encountered a similar challenge where I needed a pop-up menu action to
enable/disable based on the object class, and the object classes that would
enable the action were not known until runtime (they were defined in
contributions). Defining the enablement logic in selectionChanged() and
adding the early startup contribution resolved the issue.
