Hi, Working on a visual report designer for the upcoming fpReport. We use Canvas.DrawFocusRect() to draw a selection rectangle around a reporting element (eg: a memo). We can drag that rectangle around in the report designer (which itself is a custom widget). We call the Canvas.DrawFocusRect() from within the MouseMove event. It seems to work fine under LCL-GTK2, but could this be problematic on other platforms, as painting outside the Paint event can normally have undefined results.
Or has LCL somehow resolved the issues of painting outside the Paint event? On a side note: The Paint() event for the report designer can potentially have very lengthy code, so we definitely don't want to repaint everything simply because we are dragging a focus rectangle around on the canvas. So if we must, we can obviously work around this by using various states in the Paint method.
