Enhancement of toolbar with custom button
i have actually the task to enhance the toolbar with a custom button zcancel.
I did the necessary customizing to view the additional button in the webclient.
It works fine and looks really pretty.
But now the problem: I am not able to catch any event by click on this button, also i didnt find any customizing view where i can assing an event or a handler class to this button.
Could anyone give me a hint where toolbar buttons are assigned to handler classes / events?
Thanks in advance!
