How to speed up autosize?
« on: February 04, 2020, 11:07:12 pm »
Hi,

I have applied many of the rules of https://wiki.lazarus.freepascal.org/Autosize_/_Layout. My application now looks great with different operating systems (Windows 10, Linux Mint Xfce), with different DPI values and adapts to translated po files.

My problem: I have a resizable form with a very complex layout. Resizing the form at runtime is noticeably slower than once when the rules were not applied, especially on Windows.

Is there a way to speed up the calculation of the LCL layout? Is it useful, for example, to set MinHeight and MinWidth (constraints) for each component?

Thank you!

You have too many (10+ lol...) TWinControl on form and trying resizing width or height ... It's really crazy in 2020. Internet browsers resize 10000+ controls with no lag because there is no WinControls (only one main form)  ... but resizing 10+ native WinControls lags ass hell ...

LCL layout engine is fast. You can resize 1000+ non TWinControls with it (eg. TShape, TLabel , ...etc. ).

Try to eliminate all TWinControl based controls ...   >:D >:D >:D
