ok i found the answer in a different thread
what i’m trying to do is something like this:
i have a device with a gui in a device rack.
my application provides a gui editor for those devices.
in the rack i have a button to open the gui in said editor.
but when the gui editor opens, it has to show the gui to edit it, so it disappears in the device rack.
i only can think of the solution to take a snapshot of the gui, put in in the rack, gray it out and print something like “in edit” on top of it while it is in the editor. but thats a pretty ugly solution.
any tips welcome.
