The panel for camview, goes away leaving a blank white screen on the tab
where the camera is displayed if either dimension of that tab assigned
to the camera, is within 20 pixels of the cameras native pixels
eventually, or instantly if the window area available exceeds the
cameras 640x480 screen size. The gladevcp buttons at the bottom of that
window also go away at the same time, and at the instant it fails, logs
this to the terminal that started LCNC.
/usr/bin/gladevcp:295: Warning: g_object_ref: assertion
`object->ref_count > 0' failed
gtk.main()
Which is this paragraph in /usr/bin/gladevcp:
try:
gtk.main() <---line 295
except KeyboardInterrupt:
sys.exit(0)
finally:
halcomp.exit()
Which may as well be swahili to me. Makes absolutely no sense.
LCNC is not effected and continues to run just fine. But the only way to
get the camera back is to shut down LCNC, and restart it. Its default
size for that window results in an image whose aspect ratio is bounceing
from 1/1 to about 1/1.25 at about 5 hz when the tab is clicked on.
Seems to me that error ought to point to something aglay.
But what?
Thanks Andy.
Cheers, Gene Heskett
