I wanna modern view of my application on old systems like windows XP. How I can do it, without use FMX?
you can use VCL components with XE10, that provide you to use Native Extended Styles.
you can check this :
http://docwiki.embarcadero.com/RADStudio/Seattle/en/VCL_Styles_Overview
or
Delphi XE2 VCL styles tutorial - how to change the style at runtime
however be carefull of which version of Delphi you are using, because embarcadero change a little bit about how the TStyleManager apply styles (pre-load, at run time, ressource... there is few way to apply it).
example :
var
StyleResource : string; // filename of the style
begin
TStyleManager.LoadFromResource(HInstance, StyleResource);
