Hi,

Yet another question.. I have a menu on my tableviewer so when I do a right click I can choose to delete an object. In the handler I want to know which tableviewer is clicked so I can retrieve the input.. On this input I want to do some modifications. Is this possible?

Thanks in advance.

Regards,
Ricky de Klerck

Hi,

Are you sure that you really need exactly tableviewer? I think it's litle bit wrong from eclipse selection concepts. I mean that you can provide selection exactly from table viever and in this case selection will be element which you want to handle.

Best regards,
Arthur.

I completely agree with Arthur and therefore recommend to use
HandlerUtil.getCurrentSelection[Checked] or
HandlerUtil.getActiveMenuSelection[Checked], depending on your needs. If
it is important, that you get the control in focus, register your
(table) control via IFocusService, and use the variables
activeFocusControl and activeFocusControlId via HandlerUtil.getVariable
inside your handler.
