rulerContextMenuAboutToShow in Text Editor [message #286716]

I am extending TextEditor and I want to control the contents of the ruler
pop-up. I want to both add new items, which I've managed to do, but I want
to remove some prexisitng items. For example, I want to reomve all
references to QuickDiff.

I believe in I'm in the right area but need guidance....

can someone point me in the right direction?

Thanks

you could override isPrefQuickDiffAlwaysOn from
AbstractDecoratedTextEditor to avoid quick diff enablement.

Thanks for the advice but it doesn't seem to work.
I added this to my editor class that extends TextEditor

protected boolean isPrefQuickDiffAlwaysOn() {
return false;
}

I then did more testing and added this override code:

protected void rulerContextMenuAboutToShow(IMenuManager menu) {
super.rulerContextMenuAboutToShow(menu);
menu.remove("quickdiff.menu");
menu.remove("quickdiff");
IContributionItem[] contrib = menu.getItems();
menu.setRemoveAllWhenShown(true);
}

I analyzed the IcontributionItems list at the point of my getItems() there
are NO contributions in the list, just soem seperators.

I then added setRemoveAllWhenShown and set a breakpoint in this routine to
see what contributions exist at the end of the Show of the menu.

from ContributionManager.class
/* (non-Javadoc)
* Method declared on IContributionManager.
*/
public void removeAll() {
contributions.clear();
dynamicItems = 0;
markDirty();
}

There are these items in the list:
Add Bookmark...
Add Task...
<seperator>
Enable QuickDiff Ctrl+Shift+Q

How did they get there?! Am I goint tohave to create my own ruler or
extend ContributionManager?!

I think I've found it!

The popup menu items are being added from plugin.xml files adding to the
popup
Here's the "offending" code from
Find 'quickdiff' in
'C:\eclipse\plugins\org.eclipse.ui.editors_3.0.1\plugin.prop erties'

<extension
point="org.eclipse.ui.popupMenus">
<viewerContribution
targetID="#TextRulerContext"

now how to override succesfully i.e disable this set and use my own.

In 3.1, that contribution is gone.

Thanks Tom.

can you tell me where the contribution is documented. I can't seem to find
it in the what's new for 3.1.

I switched to 3.1 this morning and can't see any mesurable diffrenece in
behavour about overriding the plug-in settings.

Thanks again.

Ooops. I read "done" instead of "gone". Sorry.

I'm still lost to see if there's anyway to remove plug-in contributions.
The problem is worse with 3.1 as the number of Textruler items has
increased.
