drawer.h File Reference

the a2dCanvasView is a a2dView specially designed for displaying parts of a a2dCanvasDocument. It uses a a2dDrawer2D to actually redraw things from the document, by giving that a2dDrawer2D as drawing context to the document, and telling the document to redraw a certain rectangular area. At that last is what this class is for. It optimizes the areas to be redrawn after object in the document were changed. To do that it combines redraw areas to a minimal set of redrawing areas. All the administration for this and the way things will be redrawn is from this view. More...
