Dynamic visibility toolbar button [message #336317]

Hi,

I use org.eclipse.ui.menus to have a dynamic menu in toolbar. I want to
have a button in the toolbar activated and visibled only when the current
editor is one of editors "save" in my extension point.
First, I try to use an Adapter with the property visibleWhen.
Next, I try to overwrite the method isVisible of ContributionItem class
but the active editor is not loading before the method call.
This two solutions don't work, someone has an other idea?

Thanks

So you have an extension point with a couple of editor IDs, and you want
your toolitem to be visible when the active editor is one of these IDs?

If that is the case, your visibleWhen would look like:

<visibleWhen>
<with variable="activeEditorId">
<test property="com.example.inMyExtension"/>
</with>
</visibleWhen>
[/xml]

then write a property tester that can compare the string ID with your
list of IDs.

If this is not your usecase, please provide more details.

Thanks!! Use a property tester works very well.
It's the solution I tried to do.
Thanks a lot
