/**
    @class wxKeyEvent

    This event class contains information about key press and release events.

    The main information carried by this event is the key being pressed or
    released. It can be accessed using either GetKeyCode() function or
    GetUnicodeKey(). For the printable characters, the latter should be used as
    it works for any keys, including non-Latin-1 characters that can be entered
    when using national keyboard layouts. GetKeyCode() should be used to handle
    special characters (such as cursor arrows keys or @c HOME or @c INS and so
    on) which correspond to ::wxKeyCode enum elements above the @c WXK_START
    constant. While GetKeyCode() also returns the character code for Latin-1
    keys for compatibility, it doesn't work for Unicode characters in general
    and will return @c WXK_NONE for any non-Latin-1 ones. For this reason, it's
    recommended to always use GetUnicodeKey() and only fall back to GetKeyCode()
    if GetUnicodeKey() returned @c WXK_NONE meaning that the event corresponds
    to a non-printable special keys.

    While both of these functions can be used with the events of @c
    wxEVT_KEY_DOWN, @c wxEVT_KEY_UP and @c wxEVT_CHAR types, the values
    returned by them are different for the first two events and the last one.
    For the latter, the key returned corresponds to the character that would
    appear in e.g. a text zone if the user pressed the key in it. As such, its
    value depends on the current state of the Shift key and, for the letters,
    on the state of Caps Lock modifier. For example, if @c A key is pressed
    without Shift being held down, wxKeyEvent of type @c wxEVT_CHAR generated
    for this key press will return (from either GetKeyCode() or GetUnicodeKey()
    as their meanings coincide for ASCII characters) key code of 97
    corresponding the ASCII value of @c a. And if the same key is pressed but
    with Shift being held (or Caps Lock being active), then the key could would
    be 65, i.e. ASCII value of capital @c A.

    However for the key down and up events the returned key code will instead
    be @c A independently of the state of the modifier keys i.e. it depends
    only on physical key being pressed and is not translated to its logical
    representation using the current keyboard state. Such untranslated key
    codes are defined as follows:
        - For the letters they correspond to the @e upper case value of the
        letter.
        - For the other alphanumeric keys (e.g. @c 7 or @c +), the untranslated
        key code corresponds to the character produced by the key when it is
        pressed without Shift. E.g. in standard US keyboard layout the
        untranslated key code for the key @c =/+ in the upper right corner of
        the keyboard is 61 which is the ASCII value of @c =.
        - For the rest of the keys (i.e. special non-printable keys) it is the
        same as the normal key code as no translation is used anyhow.

    Notice that the first rule applies to all Unicode letters, not just the
    usual Latin-1 ones. However for non-Latin-1 letters only GetUnicodeKey()
    can be used to retrieve the key code as GetKeyCode() just returns @c
    WXK_NONE in this case.

    To summarize: you should handle @c wxEVT_CHAR if you need the translated
    key and @c wxEVT_KEY_DOWN if you only need the value of the key itself,
    independent of the current keyboard state.

    @note Not all key down events may be generated by the user. As an example,
        @c wxEVT_KEY_DOWN with @c = key code can be generated using the
        standard US keyboard layout but not using the German one because the @c
        = key corresponds to Shift-0 key combination in this layout and the key
        code for it is @c 0, not @c =. Because of this you should avoid
        requiring your users to type key events that might be impossible to
        enter on their keyboard.


    Another difference between key and char events is that another kind of
    translation is done for the latter ones when the Control key is pressed:
    char events for ASCII letters in this case carry codes corresponding to the
    ASCII value of Ctrl-Latter, i.e. 1 for Ctrl-A, 2 for Ctrl-B and so on until
    26 for Ctrl-Z. This is convenient for terminal-like applications and can be
    completely ignored by all the other ones (if you need to handle Ctrl-A it
    is probably a better idea to use the key event rather than the char one).
    Notice that currently no translation is done for the presses of @c [, @c
    \\, @c ], @c ^ and @c _ keys which might be mapped to ASCII values from 27
    to 31.
    Since version 2.9.2, the enum values @c WXK_CONTROL_A - @c WXK_CONTROL_Z
    can be used instead of the non-descriptive constant values 1-26.

    Finally, modifier keys only generate key events but no char events at all.
    The modifiers keys are @c WXK_SHIFT, @c WXK_CONTROL, @c WXK_ALT and various
    @c WXK_WINDOWS_XXX from ::wxKeyCode enum.

    Modifier keys events are special in one additional aspect: usually the
    keyboard state associated with a key press is well defined, e.g.
    wxKeyboardState::ShiftDown() returns @c true only if the Shift key was held
    pressed when the key that generated this event itself was pressed. There is
    an ambiguity for the key press events for Shift key itself however. By
    convention, it is considered to be already pressed when it is pressed and
    already released when it is released. In other words, @c wxEVT_KEY_DOWN
    event for the Shift key itself will have @c wxMOD_SHIFT in GetModifiers()
    and ShiftDown() will return true while the @c wxEVT_KEY_UP event for Shift
    itself will not have @c wxMOD_SHIFT in its modifiers and ShiftDown() will
    return false.


    @b Tip: You may discover the key codes and modifiers generated by all the
        keys on your system interactively by running the @ref
        page_samples_keyboard wxWidgets sample and pressing some keys in it.

    @note If a key down (@c EVT_KEY_DOWN) event is caught and the event handler
          does not call @c event.Skip() then the corresponding char event
          (@c EVT_CHAR) will not happen. This is by design and enables the
          programs that handle both types of events to avoid processing the
          same key twice. As a consequence, if you do not want to suppress the
          @c wxEVT_CHAR events for the keys you handle, always call @c
          event.Skip() in your @c wxEVT_KEY_DOWN handler. Not doing may also
          prevent accelerators defined using this key from working.

    @note If a key is maintained in a pressed state, you will typically get a
          lot of (automatically generated) key down events but only one key up
          one at the end when the key is released so it is wrong to assume that
          there is one up event corresponding to each down one.

    @note For Windows programmers: The key and char events in wxWidgets are
          similar to but slightly different from Windows @c WM_KEYDOWN and
          @c WM_CHAR events. In particular, Alt-x combination will generate a
          char event in wxWidgets (unless it is used as an accelerator) and
          almost all keys, including ones without ASCII equivalents, generate
          char events too.


    @beginEventTable{wxKeyEvent}
    @event{EVT_KEY_DOWN(func)}
        Process a @c wxEVT_KEY_DOWN event (any key has been pressed). If this
        event is handled and not skipped, @c wxEVT_CHAR will not be generated
        at all for this key press (but @c wxEVT_KEY_UP will be).
    @event{EVT_KEY_UP(func)}
        Process a @c wxEVT_KEY_UP event (any key has been released).
    @event{EVT_CHAR(func)}
        Process a @c wxEVT_CHAR event.
    @event{EVT_CHAR_HOOK(func)}
        Process a @c wxEVT_CHAR_HOOK event. Unlike all the other key events,
        this event is propagated upwards the window hierarchy which allows
        intercepting it in the parent window of the focused window to which it
        is sent initially (if there is no focused window, this event is sent to
        the wxApp global object). It is also generated before any other key
        events and so gives the parent window an opportunity to modify the
        keyboard handling of its children, e.g. it is used internally by
        wxWidgets in some ports to intercept pressing Esc key in any child of a
        dialog to close the dialog itself when it's pressed. By default, if
        this event is handled, i.e. the handler doesn't call wxEvent::Skip(),
        neither @c wxEVT_KEY_DOWN nor @c wxEVT_CHAR events will be generated
        (although @c wxEVT_KEY_UP still will be), i.e. it replaces the normal
        key events. However by calling the special DoAllowNextEvent() method
        you can handle @c wxEVT_CHAR_HOOK and still allow normal events
        generation. This is something that is rarely useful but can be required
        if you need to prevent a parent @c wxEVT_CHAR_HOOK handler from running
        without suppressing the normal key events. Finally notice that this
        event is not generated when the mouse is captured as it is considered
        that the window which has the capture should receive all the keyboard
        events too without allowing its parent wxTopLevelWindow to interfere
        with their processing.

/**
    @class wxPaintEvent

    A paint event is sent when a window's contents needs to be repainted.

    The handler of this event must create a wxPaintDC object and use it for
    painting the window contents. For example:
    @code
    void MyWindow::OnPaint(wxPaintEvent& event)
    {
        wxPaintDC dc(this);

        DrawMyDocument(dc);
    }
    @endcode

    Notice that you must @e not create other kinds of wxDC (e.g. wxClientDC or
    wxWindowDC) in EVT_PAINT handlers and also don't create wxPaintDC outside
    of this event handlers.


    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 wxRegionIterator class:
    @code
    // Called when window needs to be repainted.
    void MyWindow::OnPaint(wxPaintEvent& event)
    {
        wxPaintDC dc(this);

        // Find Out where the window is scrolled to
        int vbX,vbY;                     // Top left corner of client
        GetViewStart(&vbX,&vbY);

        int vX,vY,vW,vH;                 // Dimensions of client area in pixels
        wxRegionIterator upd(GetUpdateRegion()); // get the update rect list

        while (upd)
        {
            vX = upd.GetX();
            vY = upd.GetY();
            vW = upd.GetW();
            vH = upd.GetH();

            // Alternatively we can do this:
            // wxRect rect(upd.GetRect());

            // Repaint this rectangle
            ...some code...

            upd ++ ;
        }
    }
    @endcode

    @remarks
    Please notice that in general it is impossible to change the drawing of a

/**
    @class wxUpdateUIEvent

    This class is used for pseudo-events which are called by wxWidgets
    to give an application the chance to update various user interface elements.

    Without update UI events, an application has to work hard to check/uncheck,
    enable/disable, show/hide, and set the text for elements such as menu items
    and toolbar buttons. The code for doing this has to be mixed up with the code
    that is invoked when an action is invoked for a menu item or button.

    With update UI events, you define an event handler to look at the state of the
    application and change UI elements accordingly. wxWidgets will call your member
    functions in idle time, so you don't have to worry where to call this code.

    In addition to being a clearer and more declarative method, it also means you don't
    have to worry whether you're updating a toolbar or menubar identifier. The same
    handler can update a menu item and toolbar button, if the identifier is the same.
    Instead of directly manipulating the menu or button, you call functions in the event
    object, such as wxUpdateUIEvent::Check. wxWidgets will determine whether such a
    call has been made, and which UI element to update.

    These events will work for popup menus as well as menubars. Just before a menu is
    popped up, wxMenu::UpdateUI is called to process any UI events for the window that
    owns the menu.

    If you find that the overhead of UI update processing is affecting your application,
    you can do one or both of the following:
    @li Call wxUpdateUIEvent::SetMode with a value of wxUPDATE_UI_PROCESS_SPECIFIED,
        and set the extra style wxWS_EX_PROCESS_UI_UPDATES for every window that should
        receive update events. No other windows will receive update events.
    @li Call wxUpdateUIEvent::SetUpdateInterval with a millisecond value to set the delay
        between updates. You may need to call wxWindow::UpdateWindowUI at critical points,
        for example when a dialog is about to be shown, in case the user sees a slight
        delay before windows are updated.

    Note that although events are sent in idle time, defining a wxIdleEvent handler
    for a window does not affect this because the events are sent from wxWindow::OnInternalIdle
    which is always called in idle time.

    wxWidgets tries to optimize update events on some platforms.
    On Windows and GTK+, events for menubar items are only sent when the menu is about
    to be shown, and not in idle time.

/**
    @class wxClipboardTextEvent

    This class represents the events generated by a control (typically a
    wxTextCtrl but other windows can generate these events as well) when its
    content gets copied or cut to, or pasted from the clipboard.

    There are three types of corresponding events @c wxEVT_COMMAND_TEXT_COPY,
    @c wxEVT_COMMAND_TEXT_CUT and @c wxEVT_COMMAND_TEXT_PASTE.

    If any of these events is processed (without being skipped) by an event
    handler, the corresponding operation doesn't take place which allows to
    prevent the text from being copied from or pasted to a control. It is also
    possible to examine the clipboard contents in the PASTE event handler and
    transform it in some way before inserting in a control -- for example,
    changing its case or removing invalid characters.

    Finally notice that a CUT event is always preceded by the COPY event which
    makes it possible to only process the latter if it doesn't matter if the
    text was copied or cut.

    @note
    These events are currently only generated by wxTextCtrl in wxGTK and wxOSX
    but are also generated by wxComboBox without wxCB_READONLY style in wxMSW.

/**
    @class wxMouseEvent

    This event class contains information about the events generated by the mouse:
    they include mouse buttons press and release events and mouse move events.

    All mouse events involving the buttons use @c wxMOUSE_BTN_LEFT for the
    left mouse button, @c wxMOUSE_BTN_MIDDLE for the middle one and
    @c wxMOUSE_BTN_RIGHT for the right one. And if the system supports more
    buttons, the @c wxMOUSE_BTN_AUX1 and @c wxMOUSE_BTN_AUX2 events
    can also be generated. Note that not all mice have even a middle button so a
    portable application should avoid relying on the events from it (but the right
    button click can be emulated using the left mouse button with the control key
    under Mac platforms with a single button mouse).

    For the @c wxEVT_ENTER_WINDOW and @c wxEVT_LEAVE_WINDOW events
    purposes, the mouse is considered to be inside the window if it is in the
    window client area and not inside one of its children. In other words, the
    parent window receives @c wxEVT_LEAVE_WINDOW event not only when the
    mouse leaves the window entirely but also when it enters one of its children.

    The position associated with a mouse event is expressed in the window
    coordinates of the window which generated the event, you can use
    wxWindow::ClientToScreen() to convert it to screen coordinates and possibly
    call wxWindow::ScreenToClient() next to convert it to window coordinates of
    another window.

    @note Note that under Windows CE mouse enter and leave events are not natively
          supported by the system but are generated by wxWidgets itself. This has several
          drawbacks: the LEAVE_WINDOW event might be received some time after the mouse
          left the window and the state variables for it may have changed during this time.

    @note Note the difference between methods like wxMouseEvent::LeftDown and
          the inherited wxMouseState::LeftIsDown: the former returns @true when
          the event corresponds to the left mouse button click while the latter
          returns @true if the left mouse button is currently being pressed.
          For example, when the user is dragging the mouse you can use
          wxMouseEvent::LeftIsDown to test whether the left mouse button is
          (still) depressed. Also, by convention, if wxMouseEvent::LeftDown
          returns @true, wxMouseEvent::LeftIsDown will also return @true in
          wxWidgets whatever the underlying GUI behaviour is (which is
          platform-dependent). The same applies, of course, to other mouse
          buttons as well.

    This event class contains information about command events, which originate
    from a variety of simple controls.

    Note that wxCommandEvents and wxCommandEvent-derived event classes by default
    and unlike other wxEvent-derived classes propagate upward from the source
    window (the window which emits the event) up to the first parent which processes
    the event. Be sure to read @ref overview_events_propagation.

    More complex controls, such as wxTreeCtrl, have separate command event classes.

    @beginEventTable{wxCommandEvent}
    @event{EVT_COMMAND(id, event, func)}
        Process a command, supplying the window identifier, command event identifier,
        and member function.
    @event{EVT_COMMAND_RANGE(id1, id2, event, func)}
        Process a command for a range of window identifiers, supplying the minimum and
        maximum window identifiers, command event identifier, and member function.
    @event{EVT_BUTTON(id, func)}
        Process a @c wxEVT_COMMAND_BUTTON_CLICKED command, which is generated by a wxButton control.
    @event{EVT_CHECKBOX(id, func)}
        Process a @c wxEVT_COMMAND_CHECKBOX_CLICKED command, which is generated by a wxCheckBox control.
    @event{EVT_CHOICE(id, func)}
        Process a @c wxEVT_COMMAND_CHOICE_SELECTED command, which is generated by a wxChoice control.
    @event{EVT_COMBOBOX(id, func)}
        Process a @c wxEVT_COMMAND_COMBOBOX_SELECTED command, which is generated by a wxComboBox control.
    @event{EVT_LISTBOX(id, func)}
        Process a @c wxEVT_COMMAND_LISTBOX_SELECTED command, which is generated by a wxListBox control.
    @event{EVT_LISTBOX_DCLICK(id, func)}
        Process a @c wxEVT_COMMAND_LISTBOX_DOUBLECLICKED command, which is generated by a wxListBox control.
    @event{EVT_CHECKLISTBOX(id, func)}
        Process a @c wxEVT_COMMAND_CHECKLISTBOX_TOGGLED command, which is generated by a wxCheckListBox control.
    @event{EVT_MENU(id, func)}
        Process a @c wxEVT_COMMAND_MENU_SELECTED command, which is generated by a menu item.
    @event{EVT_MENU_RANGE(id1, id2, func)}
        Process a @c wxEVT_COMMAND_MENU_RANGE command, which is generated by a range of menu items.
    @event{EVT_CONTEXT_MENU(func)}
        Process the event generated when the user has requested a popup menu to appear by
        pressing a special keyboard key (under Windows) or by right clicking the mouse.
    @event{EVT_RADIOBOX(id, func)}
        Process a @c wxEVT_COMMAND_RADIOBOX_SELECTED command, which is generated by a wxRadioBox control.
    @event{EVT_RADIOBUTTON(id, func)}

    @event{EVT_SCROLLBAR(id, func)}
        Process a @c wxEVT_COMMAND_SCROLLBAR_UPDATED command, which is generated by a wxScrollBar
        control. This is provided for compatibility only; more specific scrollbar event macros
        should be used instead (see wxScrollEvent).
    @event{EVT_SLIDER(id, func)}
        Process a @c wxEVT_COMMAND_SLIDER_UPDATED command, which is generated by a wxSlider control.
    @event{EVT_TEXT(id, func)}
        Process a @c wxEVT_COMMAND_TEXT_UPDATED command, which is generated by a wxTextCtrl control.
    @event{EVT_TEXT_ENTER(id, func)}
        Process a @c wxEVT_COMMAND_TEXT_ENTER command, which is generated by a wxTextCtrl control.

        to generate such events.
    @event{EVT_TEXT_MAXLEN(id, func)}
        Process a @c wxEVT_COMMAND_TEXT_MAXLEN command, which is generated by a wxTextCtrl control
        when the user tries to enter more characters into it than the limit previously set
        with SetMaxLength().

    A focus event is sent when a window's focus changes. The window losing focus

    Notice that the set focus event happens both when the user gives focus to the
    window (whether using the mouse or keyboard) and when it is done from the
    program itself using wxWindow::SetFocus.

    The focus event handlers should almost invariably call wxEvent::Skip() on
    their event argument to allow the default handling to take place. Failure
    to do this may result in incorrect behaviour of the native controls. Also
    note that wxEVT_KILL_FOCUS handler must not call wxWindow::SetFocus() as

    @class wxHelpEvent

    A help event is sent when the user has requested context-sensitive help.

    via wxContextHelp, or (on MS Windows) by the system generating a WM_HELP message when
    the user pressed F1 or clicked on the query button in a dialog caption.

    A help event is sent to the window that the user clicked on, and is propagated
    up the window hierarchy until the event is processed or there are no more event
    handlers.

    The application should call wxEvent::GetId to check the identity of the
    clicked-on window, and then either show some suitable help or call wxEvent::Skip()
    if the identifier is unrecognised.

    Calling Skip is important because it allows wxWidgets to generate further
    events for ancestors of the clicked-on window. Otherwise it would be impossible to
    show help for container windows, since processing would stop after the first window
    found.

/**
    @class wxScrollEvent

    A scroll event holds information about events sent from stand-alone
    scrollbars (see wxScrollBar) and sliders (see wxSlider).

    Note that scrolled windows send the wxScrollWinEvent which does not derive from
    wxCommandEvent, but from wxEvent directly - don't confuse these two kinds of
    events and use the event table macros mentioned below only for the scrollbar-like
    controls.

    @section scrollevent_diff The difference between EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED

    The EVT_SCROLL_THUMBRELEASE event is only emitted when actually dragging the thumb
    using the mouse and releasing it (This EVT_SCROLL_THUMBRELEASE event is also followed
    by an EVT_SCROLL_CHANGED event).

    The EVT_SCROLL_CHANGED event also occurs when using the keyboard to change the thumb
    position, and when clicking next to the thumb (In all these cases the EVT_SCROLL_THUMBRELEASE
    event does not happen).

    In short, the EVT_SCROLL_CHANGED event is triggered when scrolling/ moving has finished
    independently of the way it had started. Please see the widgets sample ("Slider" page)
    to see the difference between EVT_SCROLL_THUMBRELEASE and EVT_SCROLL_CHANGED in action.

    @remarks
    Note that unless specifying a scroll control identifier, you will need to test for scrollbar
    orientation with wxScrollEvent::GetOrientation, since horizontal and vertical scroll events
    are processed using the same event handler.

    @beginEventTable{wxScrollEvent}
    You can use EVT_COMMAND_SCROLL... macros with window IDs for when intercepting

/**
    @class wxCloseEvent

    This event class contains information about window and session close events.

    The handler function for EVT_CLOSE is called when the user has tried to close a
    a frame or dialog box using the window manager (X) or system menu (Windows).
    It can also be invoked by the application itself programmatically, for example by
    calling the wxWindow::Close function.

    You should check whether the application is forcing the deletion of the window
    using wxCloseEvent::CanVeto. If this is @false, you @e must destroy the window
    using wxWindow::Destroy.

    If the return value is @true, it is up to you whether you respond by destroying
    the window.

    If you don't destroy the window, you should call wxCloseEvent::Veto to
    let the calling code know that you did not destroy the window.
    This allows the wxWindow::Close function to return @true or @false depending
    on whether the close instruction was honoured or not.

    Example of a wxCloseEvent handler:

    @code
        void MyFrame::OnClose(wxCloseEvent& event)
        {
            if ( event.CanVeto() && m_bFileNotSaved )
            {
                if ( wxMessageBox("The file has not been saved... continue closing?",
                                  "Please confirm",
                                  wxICON_QUESTION | wxYES_NO) != wxYES )
                {
                    event.Veto();
                    return;
                }
            }

            Destroy();  // you may also do:  event.Skip();
                        // since the default event handler does call Destroy(), too
        }
    @endcode

    The EVT_END_SESSION event is slightly different as it is sent by the system
    when the user session is ending (e.g. because of log out or shutdown) and
    so all windows are being forcefully closed. At least under MSW, after the
    handler for this event is executed the program is simply killed by the
    system. Because of this, the default handler for this event provided by
    wxWidgets calls all the usual cleanup code (including wxApp::OnExit()) so
    that it could still be executed and exit()s the process itself, without
    waiting for being killed. If this behaviour is for some reason undesirable,

    class and do not call @c event.Skip() in it (but be aware that the system
    will still kill your application).

    When a window is resized, usually only a small part of the window is damaged

    In which case, you may need to call wxWindow::Refresh to invalidate the entire window.

    @b Important : Sizers ( see @ref overview_sizer ) rely on size events to function
    correctly. Therefore, in a sizer-based layout, do not forget to call Skip on all
    size events you catch (and don't catch size events at all when you don't need to).
