### wxRadioBox::wxRadioBox

wxRadioBox()

Default constructor.

wxRadioBox(wxWindow* parent, wxWindowID id, const wxString& label, const wxPoint& point = wxDefaultPosition, const wxSize& size = wxDefaultSize, int n = 0, const wxString choices[] = NULL, int majorDimension = 0, long style = wxRA_SPECIFY_COLS, const wxValidator& validator = wxDefaultValidator, const wxString& name = "radioBox")

wxRadioBox(wxWindow* parent, wxWindowID id, const wxString& label, const wxPoint& point, const wxSize& size, const wxArrayString& choices, int majorDimension = 0, long style = wxRA_SPECIFY_COLS, const wxValidator& validator = wxDefaultValidator, const wxString& name = "radioBox")

Constructor, creating and showing a radiobox.

Parameters

parent

Parent window. Must not be NULL.

id

Window identifier. A value of -1 indicates a default value.

label

Label for the static box surrounding the radio buttons.

pos

Window position. If the position (-1, -1) is specified then a default position is chosen.

size

Window size. If the default size (-1, -1) is specified then a default size is chosen.

n

Number of choices with which to initialize the radiobox.

choices

An array of choices with which to initialize the radiobox.

majorDimension

Specifies the maximum number of rows (if style contains wxRA_SPECIFY_ROWS) or columns (if style contains wxRA_SPECIFY_COLS) for a two-dimensional radiobox.

style

Window style. See wxRadioBox.

validator

Window validator.

name

Window name.

wxPython note: The wxRadioBox constructor in wxPython reduces the `n` and `choices` arguments are to a single argument, which is a list of strings.

### wxRadioBox::~wxRadioBox

~wxRadioBox()

Destructor, destroying the radiobox item.

### wxRadioBox::Create

bool Create(wxWindow* parent, wxWindowID id, const wxString& label, const wxPoint& point = wxDefaultPosition, const wxSize& size = wxDefaultSize, int n = 0, const wxString choices[] = NULL, int majorDimension = 0, long style = wxRA_SPECIFY_COLS, const wxValidator& validator = wxDefaultValidator, const wxString& name = "radioBox")

bool Create(wxWindow* parent, wxWindowID id, const wxString& label, const wxPoint& point, const wxSize& size, const wxArrayString& choices, int majorDimension = 0, long style = wxRA_SPECIFY_COLS, const wxValidator& validator = wxDefaultValidator, const wxString& name = "radioBox")

Creates the radiobox for two-step construction. See wxRadioBox::wxRadioBox for further details.

### wxRadioBox::Enable

virtual bool Enable(bool enable = `true`)

Enables or disables the entire radiobox.

virtual bool Enable(unsigned int n, bool enable = `true`)

Enables or disables an individual button in the radiobox.

Parameters

enable

true to enable, false to disable.

n

The zero-based button to enable or disable.

wxPython note: In place of a single overloaded method name, wxPython implements the following methods:

Enable(flag) | Enables or disables the entire radiobox.
EnableItem(n, flag) | Enables or disables an individual button in the radiobox.
