    @class wxFrame

    A frame is a window whose size and position can (usually) be changed by the user.

    It usually has thick borders and a title bar, and can optionally contain a
    menu bar, toolbar and status bar. A frame can contain any window that is not
    a frame or dialog.

    A frame that has a status bar and toolbar, created via the CreateStatusBar() and
    CreateToolBar() functions, manages these windows and adjusts the value returned
    by GetClientSize() to reflect the remaining size available to application windows.

    @remarks An application should normally define an wxCloseEvent handler for the
             frame to respond to system close events, for example so that related
             data and subwindows can be cleaned up.


    @section frame_defaultevent Default event processing

    wxFrame processes the following events:

    @li @c wxEVT_SIZE: if the frame has exactly one child window, not counting the
        status and toolbar, this child is resized to take the entire frame client area.
        If two or more windows are present, they should be laid out explicitly either
        by manually handling @c wxEVT_SIZE or using sizers;
    @li @c wxEVT_MENU_HIGHLIGHT: the default implementation displays the help string
        associated with the selected item in the first pane of the status bar, if there is one.


    @beginStyleTable
    @style{wxDEFAULT_FRAME_STYLE}
           Defined as wxMINIMIZE_BOX |  wxMAXIMIZE_BOX |  wxRESIZE_BORDER |
           wxSYSTEM_MENU |  wxCAPTION |  wxCLOSE_BOX |  wxCLIP_CHILDREN.
    @style{wxICONIZE}
           Display the frame iconized (minimized). Windows only.
    @style{wxCAPTION}
           Puts a caption on the frame. Notice that this flag is required by
           wxMINIMIZE_BOX, wxMAXIMIZE_BOX and wxCLOSE_BOX on most systems as
           the corresponding buttons cannot be shown if the window has no title
           bar at all. I.e. if wxCAPTION is not specified those styles would be
           simply ignored.
    @style{wxMINIMIZE}
           Identical to wxICONIZE. Windows only.
    @style{wxMINIMIZE_BOX}
           Displays a minimize box on the frame.
    @style{wxMAXIMIZE}
           Displays the frame maximized. Windows and GTK+ only.
    @style{wxMAXIMIZE_BOX}
           Displays a maximize box on the frame. Notice that under wxGTK
           wxRESIZE_BORDER must be used as well or this style is ignored.
    @style{wxCLOSE_BOX}
           Displays a close box on the frame.
    @style{wxSTAY_ON_TOP}
           Stay on top of all other windows, see also wxFRAME_FLOAT_ON_PARENT.
    @style{wxSYSTEM_MENU}
           Displays a system menu containing the list of various windows
           commands in the window title bar. Unlike wxMINIMIZE_BOX,
           wxMAXIMIZE_BOX and wxCLOSE_BOX styles this style can be used without
           wxCAPTION, at least under Windows, and makes the system menu
           available without showing it on screen in this case. However it is
           recommended to only use it together with wxCAPTION for consistent
           behaviour under all platforms.
    @style{wxRESIZE_BORDER}
           Displays a resizable border around the window.
    @style{wxFRAME_TOOL_WINDOW}
           Causes a frame with a small title bar to be created; the frame does
           not appear in the taskbar under Windows or GTK+.
    @style{wxFRAME_NO_TASKBAR}
           Creates an otherwise normal frame but it does not appear in the
           taskbar under Windows or GTK+ (note that it will minimize to the
           desktop window under Windows which may seem strange to the users
           and thus it might be better to use this style only without
           wxMINIMIZE_BOX style). In wxGTK, the flag is respected only if the
           window manager supports _NET_WM_STATE_SKIP_TASKBAR hint.
    @style{wxFRAME_FLOAT_ON_PARENT}
           The frame will always be on top of its parent (unlike wxSTAY_ON_TOP).
           A frame created with this style must have a non-@NULL parent.
    @style{wxFRAME_SHAPED}
           Windows with this style are allowed to have their shape changed
           with the SetShape() method.
    @endStyleTable

    The default frame style is for normal, resizable frames.
    To create a frame which cannot be resized by user, you may use the following
    combination of styles:

    @code
        wxDEFAULT_FRAME_STYLE & ~(wxRESIZE_BORDER | wxMAXIMIZE_BOX)
    @endcode

    See also the @ref overview_windowstyles.

    @beginExtraStyleTable
    @style{wxFRAME_EX_CONTEXTHELP}
           Under Windows, puts a query button on the caption. When pressed,
           Windows will go into a context-sensitive help mode and wxWidgets
           will send a @c wxEVT_HELP event if the user clicked on an application
           window. Note that this is an extended style and must be set by
           calling SetExtraStyle before Create is called (two-step
           construction). You cannot use this style together with
           wxMAXIMIZE_BOX or wxMINIMIZE_BOX, so you should use
           wxDEFAULT_FRAME_STYLE  ~ (wxMINIMIZE_BOX | wxMAXIMIZE_BOX) for the
           frames having this style (the dialogs don't have a minimize or a
           maximize box by default)
    @style{wxFRAME_EX_METAL}
           On Mac OS X, frames with this style will be shown with a metallic
           look. This is an extra style.
    @endExtraStyleTable

    @beginEventEmissionTable
    @event{EVT_CLOSE(func)}
        Process a @c wxEVT_CLOSE_WINDOW event when the frame is being
        closed by the user or programmatically (see wxWindow::Close).
        The user may generate this event clicking the close button
        (typically the 'X' on the top-right of the title bar) if it's present
        (see the @c wxCLOSE_BOX style). See wxCloseEvent.
    @event{EVT_ICONIZE(func)}
        Process a @c wxEVT_ICONIZE event. See wxIconizeEvent.
    @event{EVT_MENU_OPEN(func)}
        A menu is about to be opened. See wxMenuEvent.
    @event{EVT_MENU_CLOSE(func)}
        A menu has been just closed. See wxMenuEvent.
    @event{EVT_MENU_HIGHLIGHT(id, func)}
        The menu item with the specified id has been highlighted: used to show
        help prompts in the status bar by wxFrame. See wxMenuEvent.
    @event{EVT_MENU_HIGHLIGHT_ALL(func)}
        A menu item has been highlighted, i.e. the currently selected menu item has changed.
        See wxMenuEvent.
