    @class wxButton

    A button is a control that contains a text string, and is one of the most
    common elements of a GUI.

    It may be placed on a @ref wxDialog "dialog box" or on a @ref wxPanel panel,
    or indeed on almost any other window.

    @beginStyleTable
    @style{wxBU_LEFT}
           Left-justifies the label. Windows and GTK+ only.
    @style{wxBU_TOP}
           Aligns the label to the top of the button. Windows and GTK+ only.
    @style{wxBU_RIGHT}
           Right-justifies the bitmap label. Windows and GTK+ only.
    @style{wxBU_BOTTOM}
           Aligns the label to the bottom of the button. Windows and GTK+ only.
    @style{wxBU_EXACTFIT}
           Creates the button as small as possible instead of making it of the
           standard size (which is the default behaviour ).
    @style{wxBORDER_NONE}
           Creates a flat button. Windows and GTK+ only.
    @endStyleTable

    @beginEventEmissionTable{wxCommandEvent}
    @event{EVT_BUTTON(id, func)}
           Process a wxEVT_COMMAND_BUTTON_CLICKED event, when the button is clicked.
    @endEventTable

        Constructor, creating and showing a button.

        The preferred way to create standard buttons is to use default value of
        @a label. If no label is supplied and @a id is one of standard IDs from
        @ref page_stockitems "this list", a standard label will be used.

        In addition to that, the button will be decorated with stock icons under GTK+ 2.

        @param parent
            Parent window. Must not be @NULL.
        @param id
            Button identifier. A value of wxID_ANY indicates a default value.
        @param label
            Text to be displayed on the button.
        @param pos
            Button position.
        @param size
            Button size. If the default size is specified then the button is sized
            appropriately for the text.
        @param style
            Window style. See wxButton class description.
        @param validator
            Window validator.
        @param name
            Window name.
