Apparently Analagous Threads
- [983] branches/wxruby2/wxwidgets_282: Make Window#paint work both inside and outside a paint event handler,
- [992] branches/wxruby2/wxwidgets_282/lib/wx/classes/window.rb: Fix passing of PaintEvent object in paint handler
- [973] branches/wxruby2/wxwidgets_282/swig/classes/Window.i: Fix crasher with Window#get_handle, also comment the paint method
- [980] branches/wxruby2/wxwidgets_282/samples/bigdemo/ShapedWindow.rbw: Use Window#paint instead of PaintDC.new
- [981] branches/wxruby2/wxwidgets_282/samples/caret/caret.rb: Don''t call PaintDC.new; just refresh() instead of duplicating paint code
