    @class wxSearchCtrl

    A search control is a composite control with a search button, a text
    control, and a cancel button.

    @beginStyleTable
    @style{wxTE_PROCESS_ENTER}
           The control will generate the event @c wxEVT_COMMAND_TEXT_ENTER
           (otherwise pressing Enter key is either processed internally by the
           control or used for navigation between dialog controls).
    @style{wxTE_PROCESS_TAB}
           The control will receive @c wxEVT_CHAR events for TAB pressed -
           normally, TAB is used for passing to the next control in a dialog
           instead. For the control created with this style, you can still use
           Ctrl-Enter to pass to the next control from the keyboard.
    @style{wxTE_NOHIDESEL}
           By default, the Windows text control doesn't show the selection
           when it doesn't have focus - use this style to force it to always
           show it. It doesn't do anything under other platforms.
    @style{wxTE_LEFT}
           The text in the control will be left-justified (default).
    @style{wxTE_CENTRE}
           The text in the control will be centered (currently wxMSW and
           wxGTK2 only).
    @style{wxTE_RIGHT}
           The text in the control will be right-justified (currently wxMSW
           and wxGTK2 only).
    @style{wxTE_CAPITALIZE}
           On PocketPC and Smartphone, causes the first letter to be
           capitalized.
    @endStyleTable

    @beginEventEmissionTable{wxCommandEvent}
    To retrieve actual search queries, use EVT_TEXT and EVT_TEXT_ENTER events,
    just as you would with wxTextCtrl.
    @event{EVT_SEARCHCTRL_SEARCH_BTN(id, func)}
        Respond to a @c wxEVT_SEARCHCTRL_SEARCH_BTN event, generated when the
        search button is clicked. Note that this does not initiate a search on
        its own, you need to perform the appropriate action in your event
        handler. You may use @code event.GetString() @endcode to retrieve the
        string to search for in the event handler code.
    @event{EVT_SEARCHCTRL_CANCEL_BTN(id, func)}
        Respond to a @c wxEVT_SEARCHCTRL_CANCEL_BTN event, generated when the
        cancel button is clicked.
