glade-gtk2 crash when adding MDI Action

07 Apr 2015 15:58 #57601 by DaBit
I am trying to create a simple GladeVCP panel with buttons that should trigger O-word subroutines. I did that before on my previous machine which used Ubuntu 10.04/LinuxCNC 2.5 and that was a smooth experience.

Not this time on Wheezy / LinuxCNC master as RIP. When trying to add a 'MDI Action' glade-gtk2 crashes:
(glade-3:16217): GLib-GObject-WARNING **: /build/buildd-glib2.0_2.33.12+really2.32.4-5-i386-eISom6/glib2.0-2.33.12+really2.32.4/./gobject/gtype.c:4206: type id `0' is invalid

(glade-3:16217): GLib-GObject-WARNING **: can't peek value table for type `<invalid>' which is not currently referenced
Segmentation fault

There really isn't much in the panel yet:

I am running glade-gtk2 from a terminal window where I sourced the rip-environment script and gtk2-engines/gtk2-engines-xfce is installed.

Also, I seem to be unable to set the status of a checkbox to 'checked' by default. I can set the 'Active' property to 'yes', but that is ignored.

I found a workaround that seems to avoid the crash:

1. Select "VCP Action MDI" from left panel
2. Right click widget list in top right and select "Add widget as top level".

Indeed, al those Actions should be at the top level to prevent this.

Is this problem also effecting the probe_screen panel from the russian guy 'verser' it worked great but I upgraded to latest linuxcnc version and now I get strange 'have to be in mdi mode...' error messages when I try to use it. Seems to me it is a glade problem but I have no real experience with this...

cheers, John

It is an axis problem!
It is known and will probably be solved soon.

It does work with master and gmoccapy.
