If you are using the main C++ distribution of wxWidgets, Feel free to ask any question related to wxWidgets development here. This means questions regarding to C++ and wxWidgets, not compile problems.

Post by doublemax »

There is no classical render loop in wxWidgets.

For your purpose, use a wxTimer: http://docs.wxwidgets.org/trunk/classwx_timer.html
Use the source, Luke!
