Hi,
its hard to pinpoint your problem remotely. I suggest that you try the
small examples from the following tutorial and then check the difference
to your code:

Hi,
To enable/ disable action I had used code from following link:
(http://www.eclipsezone.com/eclipse/forums/t90781.rhtml) with some
modification.
Display.getDefault().syncExec(new Runnable() {
public void run() {
IWorkbench workbench = PlatformUI.getWorkbench();
Menu menubar = workbench.getActiveWorkbenchWindow().
getShell().getMenuBar();
if(menubar == null ){
return;
}
MenuItem[] mItems = menubar.getItems();
if(mItems == null){
return;
}
for(int j = 0 ;j < menuItems.length; j++) {
if(mItems .getText().equals("Tools")){
Menu menu = mItems .getMenu();
/**************************************************
for( int i = 0; i < menu.getItemCount(); ++i) {
/**************************************************
**** In the above marked line, menu.getItemCount returns 0 but i can
**** see actions entry (menu item) in main menu and toolbar
**** after this code I am trying to get the menu Item action and
** set its state to enabled.
**** But since the code is returning 0 from above line, I am not able to
****toggle the state of the action Item
SubContributionItem cItem = null;
Object menuItemData = item.getData();
if(menuItemData == null){
continue;
}
if(menuItemData instanceof SubContributionItem){
cItem = (SubContributionItem)menuItemData;
IContributionItem conItems = cItem.getInnerItem();
if(conItems instanceof ActionContributionItem){
ActionContributionItem items = (ActionContributionItem) conItems;
String id = cItem.getId();
if((id != null) && (toolsID.contains(id))){
items.getAction().setEnabled(state);
}
}
}
}
}
}
}
});
In my code, based on this return value, I am setting the enabled
/disabled state of the icons.But since we get an empty list from
menu.getItemCount(), no further operation is possible.
This code is working perfectly fine in eclipse 3.3.2. Same code gives
problem in Eclipse 3.4.
I have not done any code changes in my application. This behavior is
observed after switching the target platform.
I have searched on net if this is a side effect of some changes in
eclipse 3.4 but did not get any solution.
Any pointers would be of great help.
Thanks,
Sneha

Hi,
I still don't have any solution to this problem. I have not yet found
whether the below mentioned problem is a known issue in Eclipse 3.4 or
whether there is a workaround to my problem.
If anybody has come across this problem, please let me know about the
solution.
Any pointers would be of great help!!
Thanks,
Sneha
