Hi all,
I'd like to associate a GTK window with a dll under Windows XP.
What I want to do is that the GTK window retrieves the messages emited from
the dll.
I wrote (just for testing) a dll wich start a timer and send a message to
the host window (my GTK window in this case) each second .
I know I have to use the gdk_window_add_filter function, but I don 't know
how to translate my GTK window to a Windows handle (HWND) and get an ID in
order to receive the messages from the dll.
I found a macro in the gdkwin32.h file that would be able to do the job:
/* Translate from drawable to Windows handle */
064 HGDIOBJ gdk_win32_drawable_get_handle (GdkDrawable *drawable);
but it doesn't work.
Here is some parts of my code:
in the main function:
HWND hWnd;
hWnd = (HWND)gdk_win32_drawable_get_handle(myApp.pWin->window);
gdk_window_add_filter(myApp.pWin->window, msgFunc, &myApp);
timer(hWnd); //start the timer
and my filter function:
GdkFilterReturn msgFunc (GdkXEvent *xevent,GdkEvent *event, gpointer
userData)
{
APPLICATION *pApp = (APPLICATION*)userData;
MSG *WndMsg = (MSG*) xevent;
if(WndMsg->message == DLL_MSG)
{
addText(pApp->pDrawArea, "DLL Message!", userData); //Display text each
time a message is sent
}
return GDK_FILTER_CONTINUE;
}
it seems that the GTK window doesn't receive any messages from the dll.
Can somebody help me ?
Thanks for advance
