Animation sample
|
|
================
|
|
|
|
Every now and then someone asks whether there are animation
|
|
classes in wxWindows. I started these animation player classes
|
|
nearly two years ago and never got round to finishing them.
|
|
Now I've done some hacking on them and (after very limited testing)
|
|
it seems to work on Windows for animated GIFs, both transparent
|
|
and non-transparent.
|
|
|
|
Basically the classes makes use of the existing GIF decoder in
|
|
wxWindows to read an animated GIF into wxGIFAnimation, and then
|
|
play that animation using wxAnimationPlayer. It's quite tied
|
|
to the animated GIF way of doing animation, so don't expect anything too generic.
|
|
However, it would be quite possible to write code to convert an animated
|
|
GIF into a PNG-based invented format, and then write a wxPNGAnimation
|
|
handler.
|
|
|
|
The next steps are:
|
|
|
|
1. Test on other platforms.
|
|
2. Write control classes to make it easy to embed animations in dialogs, etc.
|
|
See my thoughts in animate.h.
|
|
3. Write documentation.
|
|

*** IMPORTANT NOTE: to compile this, you must first edit the
|
|
file:
|
|
|
|
include/wx/gifdecod.h
|
|
|
|
and change the keyword 'protected' to 'public', then recompile
|
|
wxWindows. If you have downloaded the latest code from the CVS trunk,
|
|
the problem has been corrected already.
|
|
|
|
As an exercise, you might like to write a handler for the
|
|
PNG-based animation format:
