Re: [e4-dev] Command handler and active dialog
|
Hi Tom,
thanks for the hint. I still have tons of 3x code, but it will run on the compat layer as I'm gradually moving to 4.x. Thanks for the idea with the IEclipseContext. I think I'll give that a try. Would you release it from the context on the JFace Dialogs close or dispose method?
So long, Thomas

Is the dialog a workbench-dialog or simply a subclass from JFace-Dialog
which you open in your custom code?

Well because you control the subclass you could push the value into
Shell#setData() :-)

Well in e4 you could push the value in the IEclipseContext while the
dialog is open and which would make it subject of injection to all
command handlers @Execute but I guess you are singlesourcing for 3.x and
4.x, right?
