Hi everyone!
I'm trying to remake some of my older projects to support Aero Glass. Although it's kinda easy to enable glass frame, I've encountered some major problems. I used this code:
var
xVer: TOSVersionInfo;
hDWM: THandle;
DwmIsCompositionEnabled: function(pbEnabled: BOOL): HRESULT; stdcall;
DwmExtendFrameIntoClientArea: function(hWnd: HWND; const pxMarInset: PRect): HRESULT; stdcall;
bEnabled: BOOL;
xFrame: TRect;
// ...
xVer.dwOSVersionInfoSize := SizeOf(TOSVersionInfo);
GetVersionEx(xVer);
if xVer.dwMajorVersion >= 6 then
begin
hDWM := LoadLibrary('dwmapi.dll');
@DwmIsCompositionEnabled := GetProcAddress(hDWM, 'DwmIsCompositionEnabled');
@DwmExtendFrameIntoClientArea := GetProcAddress(hDWM, 'DwmExtendFrameIntoClientArea');
if (@DwmIsCompositionEnabled <> nil) and
(@DwmExtendFrameIntoClientArea <> nil) then
begin
DwmIsCompositionEnabled(@bEnabled);
if bEnabled then
begin
xRect := Rect(-1, -1, -1, -1);
DwmExtendFrameIntoClientArea(FrmMain.Handle, @xRect);
end;
end;
FreeLibrary(hDWM);
end;
So I got the pretty glass window now. Due to black being transparent color now (kinda stupid choice, why couldn't it be pink) anything that is clBlack becomes transparent, too. It means all labels, edits, button texts... even if I set text to some other color at design time, DWM still makes them that color AND transparent.
Well, my question would be - whether it's possible to solve this somehow?
