I’m working on an Eclipse plug-in.
With Indigo, a drop-down list in the toolbar like the one below works perfectly.
It is built like this (where the
MyList instance is dynamically constructed):
org.eclipse.ui.menus (menuContribution) locationURI : toolbar:org.eclipse.ui.main.toolbar Functions (menu) id : xxxx (dynamic) id : yyyyyyy class MyList extends ContributionItem
However, this doesn’t work on Kepler, and it’s difficult to understand why.
While I can write a dynamic drop-down list which work in main menu (
my list with the same code doesn’t appear if locate it in toolbar (
How can I create a drop-down list like the one in the screenshot above in Eclipse Kepler’s toolbar, and handle events when items are clicked?
This seems to be a compatibility issue in Eclipse 4.x. I can already reproduce the problem in a very simple example. I reported this as [a bug] you can vote on this bug if you like.
EDIT: Eclipse committer Paul Webster confirms that this doesn’t work yet. It may be possible to work around this by using instead of and extending WorkbenchWindowControlContribution instead of ContributionItem.
