Hi Remy,
I'd like to toggle form shadow at runtime, in the OnShow method, reading a
ini file.
How can I do this? Can you help me writing the right code? I think I have to
write in my header file:
//---------------------------------
virtual void __fastcall TForm1::CreateParams(TCreateParams &Params);
//--------------------------
and in the cpp file:
void __fastcall TForm1::CreateParams(TCreateParams &Params)
{
const CS_DROPSHADOW = 0x00020000;
TForm::CreateParams(Params);
Params.Style = Params.Style | CS_DROPSHADOW; //<---- is it right???
}
//--------------------------------------------------------------------------
-
How can restore in my WinXp system, form shadows?
How can I toggle shadows in my forms by code?
Thanks
Mario Sernicola
