I have problems attaching a floatcanvas/navcanvas on a wxpanel. I've
attached my code and what I'm trying to do is to is to position the
navcanvas inside a wxpanel but not maximized (I want to define where and
how big it is).
Honestly, I always use Sizers -- are you sure you can't use them for this?
Anyway, it seems that it should work, but you're right, it doesn't. I
think it's one of those things where it depends on the order that things
are created. But anyway, a work around is an extra call to SetSize:
self.navCanvas = NavCanvas.NavCanvas(self.mother)
self.navCanvas.SetSize( (1030, 533) )
No need to call this -- it happens in __init_ anyway.
self.navCanvas.Canvas.InitAll()
#for point in self.points:
# self.navCanvas.Canvas.AddPoint(point)
you might want to use a PointSet Object:
self.navCanvas.Canvas.AddPointSet(self.points)
and here a line object takes a sequence of point coordinates:
# pos = 0
# for p in range(0,len(self.points)-1):
# xy = (self.points[pos],self.points[pos+1])
# self.navCanvas.Canvas.AddLine(xy)
# pos+=1
self.navCanvas.Canvas.AddLine(self.points)
I've enclosed my edited version. It's also edited for style:
http://wiki.wxpython.org/wxPython%20Style%20Guide
Another style note: you've got a lot of nested Windows all in one class
here. That may be been for test purposes, but if not, you'll find it
easier to manage your code of you break things out into separate classes.
