When I add a number of PtText and PtComboBox to my application nothing
seems to respond. The callbacks on the buttons are not initiated and the
dropdowns don’t display anything. The shell displays the following error
many times:
Photon: GetRegion failed
What does this mean?
When I remove the majority of the widgets, the error is gone and the
application operates as it should.
Why do these widgets cause such a problem? They have no callbacks
whatsoever.
