[GRASS-dev] Re: New installation for wxPython GUI

[Michael Barton]

Just tried it on a new Debian installation of one of my students today. He
compiled wxPython from source today.

Zoom works OK. Pan works but flickers a lot. Window resizing causes the
window to blank. 

I'd like to try it on our Fedora Core 4 workstation too.

For the pan, there is a slightly different kind of bitmap drag to try. If
that doesn't work, I guess we'll have to try a buffered device context and
see if it helps.

Window resizing uses image scaling to give a visual image of the shrinking
image during resizing. After resizing stops, GRASS (render.py) re-renders
the image to fit the new window size. We can turn off image scaling and see
what happens there.
