Under GTK, there is no such all-round widget that has all the functionality. Moreover, the GTK defines a client area as a different widget from the actual widget you are handling.

The common rule for all windows is only, that the widget that interacts with the rest of GTK must be referenced in m_widget and all other widgets must be children of this widget on the GTK level. The top-most widget, which also represents the client area, must be in the m_wxwindow field and must be of - the type GtkMyFixed. + the type wxPizza. As I said, the window classes that display a GTK native widget only have one widget, so in the case of e.g. the wxButton class m_widget holds a pointer to a GtkButton widget.

If not, all input to the widget that gets pointed to by m_widget gets intercepted and sent to the class. + II) + + The design of scrolling in wxWidgets is markedly different from that offered + by the GTK itself and therefore we cannot simply take it as it is. In GTK, + clicking on a scrollbar belonging to scrolled window will inevitably move + the window. In wxWidgets, the scrollbar will only emit an event, send this + to (normally) a wxScrolledWindow and that class will call ScrollWindow() + which actually moves the window and its sub-windows. Note that wxPizza + memorizes how much it has been scrolled but that wxWidgets forgets this + so that the two coordinates systems have to be kept in synch. This is done + in various places using the pizza->m_scroll_x and pizza->m_scroll_y values. + + III) + + Singularly the most broken code in GTK is the code that is supposed to + inform subwindows (child windows) about new positions. Very often, duplicate + events are sent without changes in size or position, equally often no + events are sent at all (All this is due to a bug in the GtkContainer code + which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores + GTK's own system and it simply waits for size events for toplevel windows + and then iterates down the respective size events to all window. This has + the disadvantage that windows might get size events before the GTK widget + actually has the reported size. This doesn't normally pose any problem, but + the OpenGL drawing routines rely on correct behaviour. Therefore, I have + added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas, + i.e. the wxGLCanvas will emit a size event, when (and not before) the X11 + window that is used for OpenGL output really has that size (as reported by + GTK). + + IV) + + If someone at some point of time feels the immense desire to have a look at, + change or attempt to optimise the Refresh() logic, this person will need an + intimate understanding of what "draw" and "expose" events are and what + they are used for, in particular when used in connection with GTK's + own windowless widgets. Beware. + + V) + + Cursors, too, have been a constant source of pleasure. 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, I use idle time + to set the cursor over and over again, starting from the toplevel windows + and ending with the youngest generation (speaking of parent and 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. + */ //----------------------------------------------------------------------------- // data //----------------------------------------------------------------------------- -extern wxList wxPendingDelete;
