Question

I have the following structure,

    typedef struct _MainWin
    {
        GtkWindow parent;
        GtkWidget* scroll;
        GtkWidget* box;
    }MainWin;

I have created the application main window from this structure. Now I need the main window in full screen. When I tried to call,

gtk_window_fullscree(GTK_WINDOW(mw);

Where mw is object of MainWin. I got the following error message gtk_window_fullscreen: assertionGTK_IS_WINDOW (window)’ failed`

How can I lead mw to GtkWindow?

Thank you.

This seems wrong. Your GtkWindow should be a pointer too, and created using gtk_window_new() like any other GTK+ widget. This looks like you’re trying to “subclass” the GtkWindow struct, which I don’t think you can do like this.
