VZ
3wxWindow is the base class for all windows and represents any visible objecto n
4screen. All controls, top level windows and so on are windows. Sizers and
5device contexts are not, however, as they don't appear on screen themselves.
6
7Please note that all children of the window will be deleted automatically by
8the destructor before the window itself is deleted which means that you don't
9have to worry about deleting them manually. Please see the \helpref{window
10deletion overview}{windowdeletionoverview} for more information.
11
12Also note that in this, and many others, wxWindows classes some
13\texttt{GetXXX()} methods may be overloaded (as, for example,
14\helpref{GetSize}{wxwindowgetsize} or
15\helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
16are non-virtual because having multiple virtual functions with the same name
17results in a virtual function name hiding at the derived class level (in
18English, this means that the derived class has to override all overloaded
19variants if it overrides any of them). To allow overriding them in the derived
20class, wxWindows uses a unique protected virtual \texttt{DoGetXXX()} method
21and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
22changes the behaviour of the latter.

179Note that wxWindows maintains the stack of windows having captured the mouse
180and when the mouse is released the capture returns to the window which had had
181captured it previously and it is only really released if there were no previous
182window. In particular, this means that you must release the mouse as many times
183as you capture it.

320Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
321an opportunity for the window to choose whether to destroy the window.
322Usually it is only used with the top level windows (wxFrame and wxDialog
323classes) as the others are not supposed to have any special OnClose() logic.
a660d684
KB
324
325The close handler should check whether the window is being deleted forcibly,
24174c30
VZ
326using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
327should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.

VZ
329{\it Note} that calling Close does not guarantee that the window will be
330destroyed; but it provides a way to simulate a manual close of a window, which
331may or may not be implemented by destroying the window. The default
332implementation of wxDialog::OnCloseWindow does not necessarily delete the
333dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
334the appropriate button event handler and may do anything at all.

1863An event handler is an object that is capable of processing the events
1864sent to a window. By default, the window is its own event handler, but
1865an application may wish to substitute another, for example to allow
1866central implementation of event-handling for a variety of different
1867window classes.
1868
1869\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1870an application to set up a chain of event handlers, where an event not handled by one event handler is
1871handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
1872remove the event handler.

2463
2464Let's say you wish to display 50 lines of text, using the same font.
2465The window is sized so that you can only see 16 lines at a time.
2466
2467You would use:
2468
2469{\small%
2470\begin{verbatim}
2471 SetScrollbar(wxVERTICAL, 0, 16, 50);
2472\end{verbatim}
2473}
2474
2475Note that with the window at this size, the thumb position can never go
2476above 50 minus 16, or 34.
2477
2478You can determine how many lines are currently visible by dividing the current view
2479size by the character height in pixels.
2480
2481When defining your own scrollbar behaviour, you will always need to recalculate
2482the scrollbar settings when the window size changes. You could therefore put your
2483scrollbar calculations and SetScrollbar
2484call into a function named AdjustScrollbars, which can be called initially and also
f4fcc291 2485from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2509
2510The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2511click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2512page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2513value has to be adjusted when the window is resized, since the page size will have changed.
2514
2515In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2516the thumb changes size to reflect the page size relative to the length of the document. When the
2517document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2518will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2519disappear.
2520
2521Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2522handling of pages and ranges.

2576The range of a scrollbar is the number of steps that the thumb may travel, rather than the total

2577object length of the scrollbar. If you are implementing a scrolling window, for example, you
2578would adjust the scroll range when the window is resized, by subtracting the window view size from the
2579total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
a660d684

2580and usually the scrollbar will be automatically hidden.

2744
2745This function tells a window if it should use the system's "theme" code
2746to draw the windows' background instead if its own background drawing
2747code. This does not always have any effect since the underlying platform
2748obviously needs to support the notion of themes in user defined windows.
2749One such platform is GTK+ where windows can have (very colourful) backgrounds
2750defined by a user's selected theme.

e39af974
JS
2923
2924This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
2925the window. The particular implementation depends on the window; for
2926example a wxToolBar will send an update UI event for each toolbar button,
2927and a wxFrame will send an update UI event for each menubar menu item.
2928You can call this function from your application to ensure that your
2929UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
2930are concerned). This may be necessary if you have called
2931\helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
2932\helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
2933limit the overhead that wxWindows incurs by sending update UI events in idle time.
2934
2935{\it flags} should be a bitlist of one or more of the following values.
2936
2937\begin{verbatim}
2938enum wxUpdateUI
2939{
2940 wxUPDATE_UI_NONE = 0x0000, // No particular value
2941 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
2942 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
2943};
2944\end{verbatim}
2945
2946If you are calling this function from an OnInternalIdle or OnIdle
2947function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
2948this tells the window to only update the UI elements that need
2949to be updated in idle time. Some windows update their elements
2950only when necessary, for example when a menu is about to be shown.
2951The following is an example of how to call UpdateWindowUI from
2952an idle function.
2953
2954\begin{verbatim}
2955void MyWindow::OnInternalIdle()
2956{
2957 if (wxUpdateUIEvent::CanUpdate(this))
2958 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
