The main difficulty is that a GdkWindow inherits a cursor if the programmer sets a new cursor - for the parent.

To prevent this from doing too much harm, SetCursor calls + GTKUpdateCursor, which will recursively re-set the cursors of all child windows. Also don't forget that cursors (like much else) are connected to GdkWindows, not GtkWidgets and that the "window" field of a GtkWidget might very well point to the GdkWindow of the parent widget (-> "window-less widget") and that the two obviously have very different meanings. - */ //----------------------------------------------------------------------------- @@ -281,11 +279,11 @@ wxgtk_window_size_request_callback(GtkWidget * WXUNUSED(widget), extern "C" { static gboolean -gtk_window_expose_callback( GtkWidget* widget, +gtk_window_expose_callback( GtkWidget*, GdkEventExpose *gdk_event, wxWindow *win ) { - if (gdk_event->window == widget->window) + if (gdk_event->window == win->GTKGetDrawingWindow()) { win->GetUpdateRegion() = wxRegion( gdk_event->region ); win->GtkSendPaintEvents(); @@ -304,7 +302,10 @@ extern "C" { static gboolean expose_event_border(GtkWidget* widget, GdkEventExpose* gdk_event, wxWindow* win) { - if (gdk_event->window != widget->window) + if (gdk_event->window != gtk_widget_get_parent_window(win->m_wxwindow)) + return false; + + if (!win->IsShown()) return false; const GtkAllocation& alloc = win->m_wxwindow->allocation; @@ -1831,7 +1832,7 @@ gtk_window_realized_callback(GtkWidget* widget, wxWindow* win) if (win->m_imData) { gtk_im_context_set_client_window( win->m_imData->context, - widget->window); + win->m_wxwindow ?
