Re: [Lazarus] Unneeded Paint calls from LCL
Seems I posted too pessimistic analysis. Too many repaints are caused by atsynedit, and with an empty control (which only has overridden Paint to show counter) it’s not so bad— counter is 1, only on few WS it’s 2.

It should be possible to use "none breaking" breakpoints (without causing extra paint or focus events) and then go through the debug history to see stackframes. -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
