Detailed Description

A radio button item is a button which usually denotes one of several mutually exclusive options.

It has a text label next to a (usually) round button.

You can create a group of mutually-exclusive radio buttons by specifying wxRB_GROUP for the first in the group. The group ends when another radio button group is created, or there are no more radio buttons.

Styles

This class supports the following styles:

wxRB_GROUP:
Marks the beginning of a new group of radio buttons.
wxRB_SINGLE:
In some circumstances, radio buttons that are not consecutive siblings trigger a hang bug in Windows (only). If this happens, add this style to mark the button as not belonging to a group, and implement the mutually-exclusive group behaviour yourself.

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:

EVT_RADIOBUTTON(id, func):
Process a wxEVT_COMMAND_RADIOBUTTON_SELECTED event, when the radiobutton is clicked.

Constructor & Destructor Documentation

wxRadioButton::wxRadioButton ( )

Default constructor.

参照:: Create(), wxValidator

wxRadioButton::wxRadioButton	(	wxWindow *	parent,
		wxWindowID	id,
		const wxString &	label,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `0`,
		const wxValidator &	validator = `wxDefaultValidator`,
		const wxString &	name = `wxRadioButtonNameStr`
	)

Constructor, creating and showing a radio button.

Parameters:

parent	Parent window. Must not be NULL.
id	Window identifier. The value `wxID_ANY` indicates a default value.
label	Label for the radio button.
pos	Window position. If wxDefaultPosition is specified then a default position is chosen.
size	Window size. If wxDefaultSize is specified then a default size is chosen.
style	Window style. See wxRadioButton.
validator	Window validator.
name	Window name.

参照:: Create(), wxValidator

virtual wxRadioButton::~wxRadioButton ( ) [virtual]

Destructor, destroying the radio button item.

Member Function Documentation

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

Creates the choice for two-step construction.

See wxRadioButton() for further details.

virtual bool wxRadioButton::GetValue ( ) const [virtual]

Returns true if the radio button is checked, false otherwise.

virtual void wxRadioButton::SetValue ( bool value ) [virtual]

Sets the radio button to checked or unchecked status.

This does not cause a wxEVT_COMMAND_RADIOBUTTON_SELECTED event to get emitted.

If the radio button belongs to a radio group exactly one button in the group may be checked and so this method can be only called with value set to true. To uncheck a radio button in a group you must check another button in the same group.
