  10     @class wxSearchCtrl
  11
  12     A search control is a composite control with a search button, a text
  13     control, and a cancel button.
  14
  15     @beginStyleTable
  16     @style{wxTE_PROCESS_ENTER}
  17            The control will generate the event @c wxEVT_COMMAND_TEXT_ENTER
  18            (otherwise pressing Enter key is either processed internally by the
  19            control or used for navigation between dialog controls).
  20     @style{wxTE_PROCESS_TAB}
  21            The control will receive @c wxEVT_CHAR events for TAB pressed -
  22            normally, TAB is used for passing to the next control in a dialog
  23            instead. For the control created with this style, you can still use
  24            Ctrl-Enter to pass to the next control from the keyboard.
  25     @style{wxTE_NOHIDESEL}
  26            By default, the Windows text control doesn't show the selection
  27            when it doesn't have focus - use this style to force it to always
  28            show it. It doesn't do anything under other platforms.
  29     @style{wxTE_LEFT}
  30            The text in the control will be left-justified (default).
  31     @style{wxTE_CENTRE}
  32            The text in the control will be centered (currently wxMSW and
  33            wxGTK2 only).
  34     @style{wxTE_RIGHT}
  35            The text in the control will be right-justified (currently wxMSW
  36            and wxGTK2 only).
  37     @style{wxTE_CAPITALIZE}
  38            On PocketPC and Smartphone, causes the first letter to be
  39            capitalized.
  40     @endStyleTable
  41
  42     @beginEventEmissionTable{wxCommandEvent}
  43     To retrieve actual search queries, use EVT_TEXT and EVT_TEXT_ENTER events,
  44     just as you would with wxTextCtrl.
  45     @event{EVT_SEARCHCTRL_SEARCH_BTN(id, func)}
  46         Respond to a @c wxEVT_SEARCHCTRL_SEARCH_BTN event, generated when the
  47         search button is clicked. Note that this does not initiate a search on
  48         its own, you need to perform the appropriate action in your event
  49         handler. You may use @code event.GetString() @endcode to retrieve the
  50         string to search for in the event handler code.
  51     @event{EVT_SEARCHCTRL_CANCEL_BTN(id, func)}
  52         Respond to a @c wxEVT_SEARCHCTRL_CANCEL_BTN event, generated when the
  53         cancel button is clicked.
  54     @endEventTable
