Hi, I have coded a drawing area (which has a gdkpixbuf rendered to it), which sits inside an alignment (0.5, 0.5, 0, 0) which itself is inside a viewport associated with a GtkScrolledWindow. Scrolling works as expected, and if the window is resized to be bigger than the drawing area you see a grey border filling the area between the drawing area and the scrollbars / edge of the viewport. However, I have only been able to get mouse coordinates from the drawing area. I would like to get coordinates from the origin in the top left of the scrolled window. What do I need to do? I tried getting coords from the alignment, but that seems to cover exactly the same area as the drawing area itself... I provide a code snippet below. If anyone wants the full listing (its not long - its purely to test this implementation problem) I can send it to them. Best regards, Chris. vbox = gtk_vbox_new(FALSE, 0); gtk_container_add(GTK_CONTAINER(window), vbox); canvas->darea=gtk_drawing_area_new(); canvas->scrollarea = gtk_scrolled_window_new(NULL, NULL); alignment = gtk_alignment_new(0.5, 0.5, 0, 0);
gtk_widget_set_size_request(canvas->darea, canvas->width, canvas->height); gtk_box_pack_start(GTK_BOX(vbox), canvas->scrollarea, TRUE, TRUE, 0); horizontal = gtk_scrolled_window_get_hadjustment(GTK_SCROLLED_WINDOW(canvas->scrollarea)); vertical = gtk_scrolled_window_get_vadjustment(GTK_SCROLLED_WINDOW(canvas->scrollarea)); viewport = gtk_viewport_new(horizontal, vertical); gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW(canvas->scrollarea), alignment); gtk_container_add(GTK_CONTAINER(alignment), canvas->darea); g_signal_connect(GTK_OBJECT(canvas->darea), "expose-event", GTK_SIGNAL_FUNC(imcanvas_on_expose), (gpointer) canvas); g_signal_connect(GTK_OBJECT(canvas->darea), "motion_notify_event", GTK_SIGNAL_FUNC(imcanvas_motion_notify_event), (gpointer) canvas); g_signal_connect(GTK_OBJECT(canvas->darea), "button_press_event", GTK_SIGNAL_FUNC(imcanvas_button_press_event), (gpointer) canvas); g_signal_connect(GTK_OBJECT(canvas->darea), "button_release_event", GTK_SIGNAL_FUNC(imcanvas_button_release_event), (gpointer) canvas); gtk_widget_set_events(canvas->darea, GDK_EXPOSURE_MASK | GDK_LEAVE_NOTIFY_MASK | GDK_BUTTON_PRESS_MASK | GDK_POINTER_MOTION_MASK | GDK_POINTER_MOTION_HINT_MASK | GDK_BUTTON_RELEASE_MASK ); GTK_WIDGET_SET_FLAGS(canvas->darea, GTK_CAN_FOCUS); gtk_window_set_focus (GTK_WINDOW(window), canvas->darea); _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
