Hi,

I have an issue giving me headache :

2 button in a toolbar : Play and Stop with each one a commands/handlers attached.
i want to enable the Stop button when i click Play and inversely when i click Stop.
how the Play handler could trigger an event to enable the stop button ?
how do that in a proper way ?
thanks in advance

Francois

Hi,

you can use the expression language in combination with a custom "source" indicating the internal state. See org.eclipse.ui.services -> sourceProvider for further information. So you could save the state (playing/stopped), which you check via expression language to disable/enable the buttons.

Best regards
Adam
