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. + + What does wxWindow do? It contains the common interface for the following + jobs of its descentants: + + 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. + + 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 actaul inter- + face for this is usually in wxScrolledWidget, 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. + + Normally one might expect, that one wxWindows class would always contain + 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 widget. 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 displays a GTK native widget, + this is the only GTK widget the class manages. When the class has a client + area for drawing into and for containing children it must have at least + one more GTK widget to handle (of the type GtkMyFixed, defined in win_gtk.c), + but there can be any number of widgets, handled by a class (e.g. the frame + class handles three). 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. + + 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 GtkMyFixed 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. + +*/ //----------------------------------------------------------------------------- // data @@ -42,126 +116,66 @@ extern wxList wxPendingDelete;
