Is it possible to disable BGRAVirtualScreen redraw
« on: May 23, 2014, 05:51:45 pm »
Am using BGRAVirtualScreen in a map program upon which vectordata for road, streams etc. are drawn.

When moving the mouse over the map, current map coordinates are shown, but that works quite slow :( because BGRAVirtualScreen  redraw event is fired whenever the mouse moves over the map.

Is there some way(option?) to block redraw in connection with this? %)

Normally the Bitmap is not redrawn in this case. It is only painted, which should be quite fast.
