Hi,

it is really easy to enable or disable view action in the views toolbar and/or menu based on the current selection of a view.

But if a view is not a selection provider because it doesn't show something like a table or tree but only a form or something like that I have problems to enable/disable view actions defined in the plugin.xml. Rolling Eyes

Therefore I'm desperately searching for any advice how to do view action enablement for a view that does not register any ISelectionProvider.

Many thanks in advance for your answers.

If your view doesn't register an ISelectionProvider then the only way you can enable an action is if you create it yourself so you can update the action enabled state.

For commands/handlers you can use <with variable="activePart"> to get your IViewPart and then write a PropertyTester to return true/false as appropriate. The IEvaluationService needs to be notified when the property changes.

Hi Paul,

thanks for your answer. I had already suspected that the view actions may not be created through the plugin.xml or that I better should use commands, but I didn't find any example for this.

Thus the confirmation of an expert is really valuable for me.
