Obviously, + you cannot understand wxGTK without knowing a little about the GTK, but + some more information about what the wxWindow, which is the base class + for all other window classes, does seems required as well. + + I) + + What does wxWindow do? It contains the common interface for the following + jobs of its descendants: + + 1) Define the rudimentary behaviour common to all window classes, such as + resizing, intercepting user input (so as to make it possible to use these + events for special purposes in a derived class), window names etc. + + 2) Provide the possibility to contain and manage children, if the derived + class is allowed to contain children, which holds true for those window + classes which do not display a native GTK widget. To name them, these + classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame- + work classes are a special case and are handled a bit differently from + the rest. The same holds true for the wxNotebook class. + + 3) Provide the possibility to draw into a client area of a window. This, + too, only holds true for classes that do not display a native GTK widget + as above. + + 4) Provide the entire mechanism for scrolling widgets. This actual inter- + face for this is usually in wxScrolledWindow, but the GTK implementation + is in this class. + + 5) A multitude of helper or extra methods for special purposes, such as + Drag'n'Drop, managing validators etc. + + 6) Display a border (sunken, raised, simple or none). + + Normally one might expect, that one wxWindows window would always correspond + to one GTK widget. Under GTK, there is no such allround widget that has all + the functionality. Moreover, the GTK defines a client area as a different + widget from the actual widget you are handling. Last but not least some + special classes (e.g. wxFrame) handle different categories of widgets and + still have the possibility to draw something in the client area. + It was therefore required to write a special purpose GTK widget, that would + represent a client area in the sense of wxWindows capable to do the jobs + 2), 3) and 4). I have written this class and it resides in win_gtk.c of + this directory. + + All windows must have a widget, with which they interact with other under- + lying GTK widgets. It is this widget, e.g. that has to be resized etc and + thw wxWindow class has a member variable called m_widget which holds a + pointer to this widget. When the window class represents a GTK native widget, + this is (in most cases) the only GTK widget the class manages. E.g. the + wxStatitText class handles only a GtkLabel widget a pointer to which you + can find in m_widget (defined in wxWindow) + + When the class has a client area for drawing into and for containing children + it has to handle the client area widget (of the type GtkPizza, defined in + win_gtk.c), but there could be any number of widgets, handled by a class + 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 GtkPizza. + + 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. But windows with client areas (for drawing + and children) have a m_widget field that is a pointer to a GtkScrolled- + Window and a m_wxwindow field that is pointer to a GtkPizza and this + one is (in the GTK sense) a child of the GtkScrolledWindow. + + If the m_wxwindow field is set, then all input to this widget is inter- + cepted and sent to the wxWindows class. 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 wxWindows 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 wxWindows, 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 subchildren. Note that GtkPizza + memorizes how much it has been scrolled but that wxWindows forgets this + so that the two coordinates systems have to be kept in synch. This is done + in various places using the pizza->xoffset and pizza->yoffset values. + + III) + + Singularily the most broken code in GTK is the code that is supposes 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 optimse the Refresh() logic, this person will need an + intimate understanding of what a "draw" and what an "expose" events are and + what there 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. + +*/ //----------------------------------------------------------------------------- -// GTK callbacks for wxWindows event system +// data //----------------------------------------------------------------------------- -//----------------------------------------------------------------------------- -// expose (of m_wxwindow, not of m_widget) +extern wxList wxPendingDelete; +extern bool g_blockEventsOnDrag; +extern bool g_blockEventsOnScroll; +extern wxCursor g_globalCursor; -void gtk_window_expose_callback( GtkWidget *WXUNUSED(widget), GdkEventExpose *gdk_event, wxWindow *win ) -{ - if (!win->HasVMT()) return; - if (g_blockEventsOnDrag) return; - -/* - if (IS_KIND_OF(win,wxTreeCtrl)) - { - printf( "OnExpose from " ); - if (win->GetClassInfo() && win->GetClassInfo()->GetClassName()) - printf( win->GetClassInfo()->GetClassName() ); - printf( ".\n" ); - - printf( "x: %d \n", gdk_event->area.x ); - printf( "y: %d \n", gdk_event->area.y ); - printf( "w: %d \n", gdk_event->area.width ); - printf( "h: %d \n", gdk_event->area.height ); -} -*/ +static GdkGC *g_eraseGC = NULL; - win->m_updateRegion.Union( gdk_event->area.x, - gdk_event->area.y, - gdk_event->area.width, - gdk_event->area.height ); - - if (gdk_event->count > 0) return; - - wxPaintEvent event( win->GetId() ); - event.SetEventObject( win ); - win->ProcessEvent( event ); - - win->m_updateRegion.Clear(); -}; +// mouse capture state: the window which has it and if the mouse is currently +// inside it +static wxWindowGTK *g_captureWindow = (wxWindowGTK*) NULL; +static bool g_captureWindowHasMouse = FALSE; -//----------------------------------------------------------------------------- -// draw (of m_wxwindow, not of m_widget) +/* extern */ wxWindowGTK *g_focusWindow = (wxWindowGTK*) NULL; -void gtk_window_draw_callback( GtkWidget *WXUNUSED(widget), GdkRectangle *rect, wxWindow *win ) -{ - if (!win->HasVMT()) return; - if (g_blockEventsOnDrag) return; - -/* - printf( "OnDraw from " ); - if (win->GetClassInfo() && win->GetClassInfo()->GetClassName()) - printf( win->GetClassInfo()->GetClassName() ); - printf( ".\n" ); - - printf( "x: %d \n", rect->x ); - printf( "y: %d \n", rect->y ); - printf( "w: %d \n", rect->width ); - printf( "h: %d \n", rect->height ); -*/ +// the last window which had the focus - this is normally never NULL (except +// if we never had focus at all) as even when g_focusWindow is NULL it still +// keeps its previous value +static wxWindowGTK *g_focusWindowLast = (wxWindowGTK *)NULL; - win->m_updateRegion.Union( rect->x, rect->y, rect->width, rect->height ); - - wxPaintEvent event( win->GetId() ); - event.SetEventObject( win ); - win->ProcessEvent( event ); - - win->m_updateRegion.Clear(); -}; +// the frame that is currently active (i.e. its child has focus).
