In this sample, we will set up a simple application that:
- create a menu and 2 menus items,
- these 2 menu items create a box for the first one, and a cylinder for the second one,
- for both wxPython and PyQt
We first call the SimpleGui module, that provides a simple interface to design GUI for both PyQt, wxPython and python-xlib:
from OCC.Display.SimpleGui import *
If you want to use wxPython, just set the backend as following:
set_backend(‘wx’)
If you want to use rather PyQt, just replace the previous line with
set_backend(‘qt’)
or, for python-xlib:
set_backend(‘X’)
The next step is to init the display:
display, start_display, add_menu, add_function_to_menu = init_display()
Let’s now define the two function that create and display a box and a cylinder:
def simple_test(event=None):
display.Test()def simple_cylinder(event=None):
from OCC.BRepPrimAPI import BRepPrimAPI_MakeCylinder
s = BRepPrimAPI_MakeCylinder(60, 200)
display.DisplayShape(s.Shape())
Now we create a menu named ‘simple test’ and add the two functions:
add_menu(‘simple test’)
add_function_to_menu(‘simple test’,simple_test)
add_function_to_menu(‘simple test’,simple_cylinder)
Finally, ask the display to be rendered:
display.View_Iso()
display.FitAll()
start_display()
Here is the result under Windows XP/wxPython:
