问题
I have an e4 rcp application and I want to extend my application with a toolbar item that should change the icon URL when the user execute it.
Is there any possibility to do this as I can do it in a MPart?
回答1:
Just call the setIconURI
method of MToolItem
in your handler for the tool item:
@Execute
public void execute(MToolItem mitem)
{
mitem.setIconURI("platform:/plugin/......");
... other code
}
