Package wx :: Class PaintEvent |
|
object
--+ |Object
--+ |Event
--+ | PaintEvent
A paint event is sent when a window's contents needs to be repainted.
Note that in an EVT_PAINT handler the application must always create
a wx.PaintDC
object, even if you do not use it. Otherwise MS
Windows assumes that the window has not been painted yet and will send
the event again, causing endless refreshes.
You can optimize painting by retrieving the rectangles that have been
damaged using wx.Window.GetUpdateRegion
and/or wx.RegionIterator
,
and only repainting these rectangles. The rectangles are in terms of
the client area, and are unscrolled, so you will need to do some
calculations using the current view position to obtain logical,
scrolled units.
