change Style Sheet by programming

["Alain Roger" <raf.news@xxxxxxxxx>]

Hi,

I'm creating a Class which should allow user to setup the default theme CSS
file he would like to use to render a class object.
therefore i have a simple function :

   public function SetTheme(string $ThemeName)
   {
       $this->m_ThemeUsed = $ThemeName;
   }

which set the theme (CSS file) to use to render my object.

However, how can i tell to my class to render or update his render with new
CSS file theme ?
can it be possible to provoke something like a refresh ?

Or it is only a CSS or JS topic ?

thanks a lot,
