Beyond moving to OpenGL I'm not certain there is a 'go faster' fix for this.
I am writing a CAD program and one part of it, naturally, includes a Cursor and within a StatusBar X and Y co-ordinates, amongst other things.
Restricting operation to movement and updating of the Cursor or updating the StatusBar then things are 'acceptable' although I would like better performance.
If I try to update the X and Y values in the StatusBar and update the Cursor
PanelMain.StatusBar1.Panels[1].Text := 'X' + ArrayXLoc[Step];
PanelMain.StatusBar1.Panels[2].Text := 'Y' + ArrayYLoc[Step];
PanelMain.StatusBar1.Update;
Things turn to treacle.
In order to draw the cursor I have two BitMaps one, OutPMap, stores an 'image' of the on screen TImage. It gets copied to the other, CurPMap, on which I draw the Cursor. CurPmap is then transferred to the on screen TImage. Something like,
CurPMap.Canvas.Draw(0,0,OutPMap);
[Scribble the cursor on CurPmap];
DrawImage.Canvas.Draw(0,0,CurPMap);
Any suggestions or is it just the way it is?
