Hello,
I'm trying to embed the VLC player (using the videolan DLLS) in a LCL
application. On Windows, this works fine. On Linux, this does not work.
The reason is that the VideoLan library expects the native window handle.
On Windows, TWinControl.Handle provides this.
On Linux, TWinControl.Handle returns the GTK widget pointer if I'm using
GTK. (I imagine it will be something similar when using Qt)
How can I get access to the low-level X window handle (id) of a TWinControl
on Linux ?
It's not so problematic. Look at qtx11.inc in lcl/widgetset/qt or in
gtk2widgetset.inc (there's IFDEF X11 or similar) which gets X11 TWindow from
GdkWindow.
Actually, it is in gtk2proc, FormToX11Window :-)
Thanks.
The function could accept a TWinControl instead of TCustomForm I would think.
Maybe an overloaded version can be added. The code is the same.
I'd even suggest adding a GetNativeHandle : Pointer to TWinControl,
but I suspect that will encounter some resistance :-)
Michael.
