Trying to do a simple thing as drawing a straight line from one place to an
other on a canvas (not between shapes). I use the command:
line.SetEnds(100,100,200,200), but python crashes when I include this
sentence!
Am I doing it wrong?
I don't know. Please provide a small sample.

Ok. I've made a small code sample and the same thing happens:
from wxPython.wx import *
from wxPython.ogl import *
wxOGLInitialize()
class Canvas(wxShapeCanvas):
def __init__(self, parent):
wxShapeCanvas.__init__(self, parent)
self.diagram = wxDiagram()
self.SetDiagram(self.diagram)
self.diagram.SetCanvas(self)
line = wxLineShape()
line.SetCanvas(self)
line.SetPen(wxBLACK_PEN)
line.SetBrush(wxBLACK_BRUSH)
line.SetEnds(10,10,200,200)
self.diagram.AddShape(line)
line.Show(True)
class TestApp(wxApp):
def OnInit(self):
frame = wxFrame(None, -1, "Test App")
self.SetTopWindow(frame)
canvas = Canvas(frame)
frame.Show(1)
return 1
if __name__ == "__main__":
app = TestApp()
app.MainLoop()
If i remove the lines:
line.SetEnds(10,10,200,200)
self.diagram.AddShape(line)
...it doesn't crash, but I still don't have my line

Stupid OGL does not create control points for the line endings automatically, so you have to do it yourself by calling
line.MakeLineControlPoints(2)
