I just installed KLayout 0.24.10 on Xubuntu 16.04 and am having problems with existing scripts that are working fine under the same Windows version. Note that unfortunately, I cannot update to the latest KLayout version, as our large library of Ruby scripts isn't 100% compatible yet. Now to the error:
After opening KLayout and the Macro Development (Ruby) window, I entered the following in the Console:
RBA::QMessageBox::information(RBA::Application.instance.main_window, "Title", "Message")
which gives the following traceback:
Unexpected object type (expected argument of class QWidget_Native, got RBA::MainWindow) in QMessageBox_Native::information
<main>:in `information'
<main>:in `<main>'
I am suspecting a Qt problem on my Ubuntu box, but don't really know what to look for, any help would be highly appreciated.

I just tried in a virtual box with Xubuntu 14.04 in it, the error isn't there and the message box displays as expected.
So here's a summary, KLayout version is always 0.24.10. I also included the reported Qt version from KLayout's About Qt dialog. Interestingly the Qt version reported by Ubuntu's package manager doesn't always match that exactly, as I found out through running
apt-cache show libqtcore4 |grep Version
.Hope that provides some clues...
Hi,
0.24.10 is actually quite old, so I'd need to dig deep to find the root cause.
I recall that this issue was there in 0.25.x too and got fixed, but it will be very hard to backport this fix as 0.24.x has deviated significantly.
As a quick workaround I think you can also use "nil" as the parent widget. This will make the message box become a detached main window, but I think that is acceptable.
Kind regards,
Matthias
