wxWindow is the base class for all windows. Any children of the window will be deleted
automatically by the destructor before the window itself is deleted.
-Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
-help text. These must not be called by a user program and are documented only for illustration.
-On several platforms, only a few of these handlers are actually written (they are not always
-needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
-the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
-platform can implement its native behaviour or just ignore the event if nothing needs to be
-done.

-The purpose of this call is to provide a safer way of destroying a window than using
-the {\it delete} operator.
+This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
+handler usually tries to close the window. It doesn't close the window itself,

+Close calls the \helpref{close handler}{wxcloseevent} for the window, providing

+classes) as the others are not supposed to have any special OnClose() logic.
The close handler should check whether the window is being deleted forcibly,

-provides a way to simulate a manual close of a window, which may or may not be implemented by
-destroying the window. The default implementation of wxDialog::OnCloseWindow does not
-necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
-itself only hides the dialog.

+central implementation of event-handling for a variety of different

-This function is only relevant to top-level windows (frames and dialogs), and under

-you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
-the window won't get the event.
+\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

-\membersection{wxWindow::OnCloseWindow}\label{wxwindowonclosewindow}
+Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
+will receive a hotkey event. It will receive the event even if the application is in the background
+and does not have the input focus because the user is working with some other application.
-\func{void}{OnCloseWindow}{\param{wxCloseEvent\& }{event}}
+\wxheading{Parameters}
-This is an event handler function called when the user has tried to close a a frame
-or dialog box using the window manager (X) or system menu (Windows). It is
-called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
-that the application can also invoke the handler programmatically.
+\docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If
+this function is called from a shared DLL, it must be a system wide unique identifier between 0xC000 and 0xFFFF.
+This is a MSW specific detail.}
-Use the EVT\_CLOSE event table macro to handle close events.
+\docparam{modifiers}{A bitwise combination of {\tt wxMOD\_SHIFT}, {\tt wxMOD\_CONTROL}, {\tt wxMOD\_ALT}
+or {\tt wxMOD\_WIN} specifying the modifier keys that have to be pressed along with the key.}
-You should check whether the application is forcing the deletion of the window
-using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
-destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
-If not, it is up to you whether you respond by destroying the window.
+\docparam{virtualKeyCode}{The virtual key code of the hotkey.}
-(Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
-the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
-it is not possible to skip window deletion.)
+\wxheading{Return value}
-If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
-let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
-to return TRUE or FALSE depending on whether the close instruction was honoured or not.
+{\tt true} if the hotkey was registered successfully. {\tt false} if some other application already registered a
+hotkey with this modifier/virtualKeyCode combination.
\wxheading{Remarks}
-The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
-for backward compatibility with earlier versions of wxWindows. The
-default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
-destroying the window if it returns TRUE or if the close is being forced.
+Use EVT\_HOTKEY(hotkeyId, fnc) in the event table to capture the event.
+This function is currently only implemented under MSW.

-\docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
-
-\wxheading{Remarks}
-
-Use the EVT\_PAINT macro in an event table definition to intercept paint events.
-
-Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object,
-even if you do not use it. Otherwise, under MS Windows, refreshing for this and other windows will go wrong.
-
-For example:

- {
- wxPaintDC dc(this);
-
- DrawMyDocument(dc);
- }
-\end{verbatim}

-
-You can optimize painting by retrieving the rectangles
-that have been damaged and only repainting these. The rectangles are in
-terms of the client area, and are unscrolled, so you will need to do
-some calculations using the current view position to obtain logical,
-scrolled units.
-
-Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
-
-{\small%
-\begin{verbatim}
-// Called when window needs to be repainted.
-void MyWindow::OnPaint(wxPaintEvent\& event)
-{
- wxPaintDC dc(this);
-
- // Find Out where the window is scrolled to

- wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
-
- while (upd)

- vX = upd.GetX();
- vY = upd.GetY();
- vW = upd.GetW();

-
- // Alternatively we can do this:

+example a wxToolBar will send an update UI event for each toolbar button,
+and a wxFrame will send an update UI event for each menubar menu item.
+You can call this function from your application to ensure that your
+UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
+are concerned). This may be necessary if you have called
+\helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
+\helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
+limit the overhead that wxWindows incurs by sending update UI events in idle time.

+\begin{verbatim}
+enum wxUpdateUI
+{
+ wxUPDATE_UI_NONE = 0x0000, // No particular value
+ wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
+ wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
+};
+\end{verbatim}
+
+If you are calling this function from an OnInternalIdle or OnIdle
+function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
+this tells the window to only update the UI elements that need
+to be updated in idle time. Some windows update their elements
+only when necessary, for example when a menu is about to be shown.
