how to disable perspective's popup menu item [message #674579]

perspective's popup menu/context menu has items like 'Save As...', 'Reset', 'Close', 'Dock On'....

would like to disable 'close' in that context menu.

Have done some search in this forum and saw some threads saying as not possible.
Is this something possible ?

No, it is not possible to customize the current perspective switcher. That menu item is added in org.eclipse.ui.internal.PerspectiveSwitcher.createPopup(ToolBar, IPerspectiveDescriptor).

You would have to completely implement your own perspective switcher, similar to the code used by PerspectiveSwitcher.

You can add you handler for command org.eclipse.ui.window.closePerspective:
<plugin>
<extension
point="org.eclipse.ui.handlers">
<handler
class="example.commands.UnsupportedCommandEliminator"
commandId="org.eclipse.ui.window.closePerspective">
</handler>
</extension>
</plugin>

(dirty solution)

or replace functionality of PerspectiveBarManager. For example for disable perspective bar menu you can use following code (is called in startup):

private void disablePerspectiveToolbarMenu() {
IWorkbenchWindow workbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (workbenchWindow == null) {
return;
}
PerspectiveBarManager perspectiveBarManager = ((WorkbenchWindow)workbenchWindow).getPerspectiveBar();
if (perspectiveBarManager == null) {
return;
}
ToolBar toolBar = perspectiveBarManager.getControl();
Listener[] listeners = toolBar.getListeners(SWT.MenuDetect);
if (listeners != null){
for (Listener listener : listeners){
toolBar.removeListener(SWT.MenuDetect, listener);
}
}
}

I'll just add that removing the menus won't work in eclipse 4.x with the compat layer as the perspective switcher implementation has changed.
