[Octave-bug-tracker] [bug #42458] fltk print doesn't produce file if window is minimized in XFCE or LXDE

[Mike Miller]

Follow-up Comment #6, bug #42458 (project octave):

Thanks Andy, I can confirm this also with GNOME 2.

I think the key is to look at the "map_state" attribute of an X window. You
can view this from the command line with


xwininfo -id WINDOWID | grep "Map State"


where WINDOWID is the hex window identifier of the figure. You can in turn get
the ID with something like


xwininfo -tree -root | grep "Figure 1"


after the figure is opened and visible.

I see that attribute go to IsUnmapped using GNOME 2 when the figure is either
minimized or moved to another virtual desktop. When I get a chance to test
current GNOME 3 again, I suspect it will stay IsViewable, and printing to a
file does work there.

If you can confirm with XFCE and LXDE that the attribute goes to IsUnmapped
when a figure is either minimized or moved to another viewport, then it looks
like it's all the same symptom. In which case, I'll add that information to
bug #33180 and that can be the one bug to track being able to print an
unrendered plot.
