Which is the most efficient method to display a grid of about 1000 clickable images in wxPython ?
Currently i am using a GridSizer filled with StaticBitmap objects. But its quite slow for 500+ images. 
One more thing is that, i have a listbox of categories on the left. That is to filter the images. Categories will be like "All", "Cat 1", "Cat 2" etc. When i click "All", all the image have to be displayed.
How i am doing this currently :

A VERTICAL BoxSizer will contain n
GridSizer objects, one for each
category. I add the StaticBitmap
objects to multiple GridSizers
depending on the categories it
belongs to. 
Then i display only that    GridSizer
depending on which category    is
selected

This method is also terribly slow for anything over 300 images. So, how do i achieve the same effect efficiently ?

I would think a ListCtrl in ICON style would be the best way to do this.
If you look at the wxPython Demos, the UltimateListCtrl sample in the wx.LC_ICON style is a good example of what you could create.
