How to scale form/controls/fonts when switch to higher screen resolution ? Of course I mean : how to do this in KOL ? Maybe some function is required ? I have form which has to work properly in 640x480 and above but under 1024x768 is horrible small with small fonts and even maximized - controls are small and fonts too.
What about sizers in KOL ? How to implement them ?

Можно вручную написать такой объект для масштабирования размеров контролов. Я как-то делал подобное, но не объектом, а функцией, которая размеры контролов масштабировала для соответствующего разрешения. Делается просто, например так:

mx := <текущее разрешение> / <эталонное разрешение, относительно которого задаются размеры>; // это по Х.
my := ... // аналогично по Y.
r.Left := Round( r.Left * mx );
r.Top := Round( r.Top * my );
r.Right := Round( r.Right * mx );
r.Bottom := Round( r.Bottom * my );

И получаем размеры в масштабе. Нужно только поймать изменение разрешения.

Better if form could have such property to do it for all controls automatically (should somehow compare resolution when program is compiled and adjust if is changed at run-time).Also font size should be fixed or scaled to proper resolution (in my windows I could set font size to small/normal/big in desktop settings, but only menu text is scaled properly,button captions are still very small).
Vladimir , could it be possible ?

Autosize=true for all control;
+ Align for all controls (+Margins) to provide correct placing/spacing controls;
+ Once calculate Font.FontHeight needed and then assign it to Form (better to a panle placed on a form), and for each TC_ages[ ] of TabControls - the same (again, better to assign to a panel placed on a page).

If Font is never changed adjusted in the project, default font which can be scaled automatically used. But it is ugly.
