If you combine pan and picking (+ move) you get a real strange behavior.
Could you please explain this strange behavior?
Mouse based zoom will be implemented later.

Well, I would say yes:
- You should take into account the position of the mouse for the zoom.
- If you combine pan and picking (+ move) you get a real strange
behavior.

Yes, it is better with this version (no more exception) but the
rectangle has no color (black).

It should come from my version of pyopengl: 3.0.0b3 which fails
determining the size of the argument (tuple) into
ListHandler.arraySize…

Hum, it is a simple name mangling for
“private” variables. But I still
do not why self.__color cannot be called from
self.__createDisplayList().

Hello,
I’ve just tried your demo with Python 2.5.2 and wxPython
2.8.6.1/2.8.8.1 but I get an error. With winpdb, I saw that while
initializing the rectangle, all variables (__xxx) are not
created and
instead variables are created with the name _Rectangle__xx…
I really do not know where this comes from.
If you have any idea, while I’m trying to find out what happens…

Hi,
I am trying to create an enhanced GLCanvas where you can create
custom shapes, auto picking, zoom, pan and etc. The first
attempt is
here and it’s working fine at this stage. Right now you have only
‘Rectangle’ object to draw.
I would like to add wxPython events to these custom object that can
be drawn on canvas… Earlier I was thinking to add run time
methods to
instances but it’s
ugly and I am not sure if wxPython events can help me out here. If
“yes” then I would like to have a guide line for implementation.
1…Mouse wheel (zoom in-out)
2.Middle Drag (pan)
- Left Down (pick)

Could you please explain this strange behavior?
For example:
- launch you Demo application,
- left-click on the rectangle and drag it from the left side to the right side of the window,
- move it back to the left side using middle-button,
- then if you click on the rectangle, it is not picked (nothing printed in the console) but if you click on its previous position (right side) you pick it!
...
Unless something does not work properly on my side (my rectangle is still black)...
