Hi there!
I'd like to open multiple windows (with qt backend) for 3D display. Here's a
simple example:
###############
import OCC.Display.SimpleGui
#Open the first Window
OCC.Display.SimpleGui.set_backend('qt')
display, start_display, add_menu, add_function_to_menu =
OCC.Display.SimpleGui.init_display()
start_display()
#Make sure the old object are destroyed:
del display
del start_display
#Now do the same thing again after the old window is closed, this one throws
an exception:
OCC.Display.SimpleGui.set_backend('qt')
display, start_display, add_menu, add_function_to_menu =
OCC.Display.SimpleGui.init_display()
start_display()
###############
The Exception which is thrown now:
QWidget: Must construct a QApplication before a QPaintDevice
Aborted (Speicherabzug geschrieben)
How can I get this to work?
Further I'd like to know whether it is possible to open the window for
display but let the code continue.
Thanks in advance for your help!
Sebastian
