/**
    @class wxStatusBar

    A status bar is a narrow window that can be placed along the bottom of a frame
    to give small amounts of status information. It can contain one or more fields,
    one or more of which can be variable length according to the size of the window.

    wxStatusBar also maintains an independent stack of status texts for each field
    (see PushStatusText() and PopStatusText()).

    Note that in wxStatusBar context, the terms @e pane and @e field are synonyms.

    @beginStyleTable
    @style{wxSTB_SIZEGRIP}
        Displays a gripper at the right-hand side of the status bar which can be used
        to resize the parent window.
    @style{wxSTB_SHOW_TIPS}
        Displays tooltips for those panes whose status text has been ellipsized/truncated
        because the status text doesn't fit the pane width.
        Note that this style has effect only on wxGTK (with GTK+ >= 2.12) currently.
    @style{wxSTB_ELLIPSIZE_START}
        Replace the beginning of the status texts with an ellipsis when the status text
        widths exceed the status bar pane's widths (uses wxControl::Ellipsize).
    @style{wxSTB_ELLIPSIZE_MIDDLE}
        Replace the middle of the status texts with an ellipsis when the status text
        widths exceed the status bar pane's widths (uses wxControl::Ellipsize).
    @style{wxSTB_ELLIPSIZE_END}
        Replace the end of the status texts with an ellipsis when the status text
        widths exceed the status bar pane's widths (uses wxControl::Ellipsize).
    @style{wxSTB_DEFAULT_STYLE}
        The default style: includes
        @c wxSTB_SIZEGRIP|wxSTB_SHOW_TIPS|wxSTB_ELLIPSIZE_END|wxFULL_REPAINT_ON_RESIZE.
    @endStyleTable

    @remarks
    It is possible to create controls and other windows on the status bar.
    Position these windows from an OnSize() event handler.

    @remarks
    Notice that only the first 127 characters of a string will be shown in
    status bar fields under pre-XP MSW systems (or even under later systems if
    a proper manifest indicating that the program uses version 6 of common
    controls library is not used). This is a limitation of the native control
    on these platforms.

        For example, to create one fixed width field of width 100 in the right part of

        @remarks The widths of the variable fields are calculated from the total
                 width of all fields, minus the sum of widths of the
                 non-variable fields, divided by the number of variable fields.
