Inheritance diagram for wxSearchCtrl:

Detailed Description

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

Styles

This class supports the following styles:

wxTE_PROCESS_ENTER:
The control will generate the event wxEVT_COMMAND_TEXT_ENTER (otherwise pressing Enter key is either processed internally by the control or used for navigation between dialog controls).
wxTE_PROCESS_TAB:
The control will receive 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.
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.
wxTE_LEFT:
The text in the control will be left-justified (default).
wxTE_CENTRE:
The text in the control will be centered (currently wxMSW and wxGTK2 only).
wxTE_RIGHT:
The text in the control will be right-justified (currently wxMSW and wxGTK2 only).
wxTE_CAPITALIZE:
On PocketPC and Smartphone, causes the first letter to be capitalized.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxCommandEvent& event)

Event macros for events emitted by this class:

To retrieve actual search queries, use EVT_TEXT and EVT_TEXT_ENTER events, just as you would with wxTextCtrl.

EVT_SEARCHCTRL_SEARCH_BTN(id, func):
Respond to a 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
```
 event.GetString() 
```
to retrieve the string to search for in the event handler code.
EVT_SEARCHCTRL_CANCEL_BTN(id, func):
Respond to a wxEVT_SEARCHCTRL_CANCEL_BTN event, generated when the cancel button is clicked.

Member Function Documentation

bool wxSearchCtrl::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxString &	value = `wxEmptyString`,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `0`,
		const wxValidator &	validator = `wxDefaultValidator`,
		const wxString &	name = `wxSearchCtrlNameStr`
	)

Creates the text control for two-step construction.

This method should be called if the default constructor was used for the control creation. Its parameters have the same meaning as for the non-default constructor.

Reimplemented from wxTextCtrl.

wxString wxSearchCtrl::GetDescriptiveText ( ) const

Return the text displayed when there is not yet any user input.

virtual wxMenu* wxSearchCtrl::GetMenu ( ) [virtual]

Returns a pointer to the search control's menu object or NULL if there is no menu attached.

virtual bool wxSearchCtrl::IsCancelButtonVisible ( ) const [virtual]

Returns the cancel button's visibility state.

virtual bool wxSearchCtrl::IsSearchButtonVisible ( ) const [virtual]

Returns the search button visibility value.

If there is a menu attached, the search button will be visible regardless of the search button visibility value.

This always returns false in Mac OS X v10.3

void wxSearchCtrl::SetDescriptiveText ( const wxString & text )

Set the text to be displayed in the search control when the user has not yet typed anything in it.

virtual void wxSearchCtrl::SetMenu ( wxMenu * menu ) [virtual]

Sets the search control's menu object.

If there is already a menu associated with the search control it is deleted.

Parameters:

menu	Menu to attach to the search control.

virtual void wxSearchCtrl::ShowCancelButton ( bool show ) [virtual]

Shows or hides the cancel button.

virtual void wxSearchCtrl::ShowSearchButton ( bool show ) [virtual]

Sets the search button visibility value on the search control.
