extend qt platform plugin

[cic1988]

Hello all,

is it possible to extend the platform plugin(instead of re-write most of them...)?
my project only needs some access to the native handle in windows.

Ive seen the source that the QWindowsNativeInterface has only implemented HWND and DC.
To my project i need some other Handles like Font and Cursor.

Thank you.

Yes, that is possible.
Qt's source should be part of whatever download you used and it is available in a public git repository.

Cheers,

There should be no need to extend the platform plugin. Once you have the HWND or HDC, you can use Windows API calls to get what you want:

HFONT hFont = (HFONT)( ::SendMessage( hWnd, WM_GETFONT, 0, 0 ) );
 
HGDIOBJ GetCurrentObject( HDC hdc,  UINT uObjectType );
 
HCURSOR WINAPI GetCursor(void);

HFONT hFont = (HFONT)( ::SendMessage( hWnd, WM_GETFONT, 0, 0 ) );

HGDIOBJ GetCurrentObject( HDC hdc,  UINT uObjectType );

HCURSOR WINAPI GetCursor(void);

To copy to clipboard, switch view to plain text mode

Thx, this sounds good.
