# Tests embedding hatari with three different methods:
|
|
# "hatari": ask Hatari to reparent to given window
|
|
# "sdl": Give SDL window into which it should reparent
|
|
# -> SDL doesn't handle (mouse, key, expose) events
|
|
# although according to "xev" it's window receives them!
|
|
# Bug in SDL (not one of the originally needed features?)?
|
|
# "reparent": Find Hatari window and reparent it into pygtk widget in python
|
|
# - Needs "xwininfo" and "awk"
|
|
#
|
|
# Using three alternative widgets:
|
|
# "drawingarea"
|
|
# "eventbox"
|
|
# "socket"
|
|
#
|
|
# Results:
|
|
# reparent+eventbox
|
|
# -> PyGtk reparents Hatari under something on rootwindow instead
|
|
# (reparening eventbox under Hatari window works fine though...)
|
|
# reparent+socket
|
|
# -> Hatari seems to be reparented back to where it was
|
|
# sdl+anything
|
|
# -> all events are lost
|
|
# hatari+socket
|
|
# -> seems to work fine
