Re: setting the wait mouse cursor during a longer load operation (solved)

[Stefan Kost <kost imn htwk-leipzig de>]

to finish the discussion - here is the final code:

// it is not nice to access the *private* member of the window, butthere is
currently no other way
GdkWindow *window=GTK_WIDGET(self->private->main_window)->window;
GdkCursor *cursor=gdk_cursor_new(GDK_WATCH);

// set wait curosr and gray-out window
gdk_window_set_cursor(window,NULL);
gdk_cursor_unref(cursor)
gtk_widget_set_sensitive(GTK_WIDGET(self->private->main_window),TRUE);

// do loading ...

// restor the cursor and enable the window
gdk_window_set_cursor(window,NULL);
gtk_widget_set_sensitive(GTK_WIDGET(self->private->main_window),TRUE);
