Context Menu Toggle Command [message #334528]

Hello,

I'm trying to build a toggle-style context menu with the command
framework. While the command framework does offer a way to specifiy such
toggle commands, I can find no mentioning of how the toggle would be
represented in a context menu. Additionally, I can not see a way to
specify the actual toggle state depending on the context (I have to use
project natures) - only global ways to do this appear to be available. I
need to change this state when the user changes the current selection.

Can this be achieved using the command framework or do I have to revert
to popupActions or even use two separate commands for addition and
removal of my nature?

Regards
Damian Philipp

See some of the examples for toggle, checked, and radio commands in
http://wiki.eclipse.org/Menu_Contributions#Example_Matrix

You can update your menus checked state or label using
updateElement(UIElement element, Map parameters) from IElementUpdater in
your handler.

It doesn't support setting the state declaratively yet,
