Hi, i’m making my first project on raspberry Pi and the 7" official display, a touch control for Aquarium Pumps.
I’ve made some custom controls (with canvas) to manage better the touch interface, it works all well, but when i quit the app
i found some errors on the command line:
gtk_fixed_move_internal: assertion `widget->parent == GTK_WIDGET (fixed)’ failed
one row for every custom controls that i put on screen.
It doesn’t affect the operation of my program, but if i can understand the origin of this messages it would be nice.
thanks all
