I create a dialog and then to do a task in the background I hide it using
dlg.visible = "NO". Now the program is executing in the background and once
it finishes the task function it will return to the function that made it
invisible and the show it again using dlg.visible = "YES".
Something Like:
dlg.visible = "NO"
doTask()
dlg.visible = "YES"
I have also re-routed print and io.write to output to a text box on the dlg
itself.
Now the problem is this: When the program is running in the background
(doTask function) and it encounters an error which is not caught using
pcall then it would never reach the dlg.visible = "YES" to make the dialog
visible but goes back to the IUP Mainloop after writing the error in the
dialog text box. So now I have no way of accessing the dialog and I have to
kill the process.
If I remove dlg.visible="NO" then I see that the error displays the
message on the text box and then returns to the main loop and then it
continues.
So I was wondering if on error the dlg can be made visible
automatically.
