See: Overview events, *wxRadioButton*, *wxCheckBox*

This class is derived (and can use functions) from: *wxControl* *wxWindow* *wxEvtHandler*

wxWidgets docs: wxRadioBox

## EVENTS

Event types emitted from this class: *command\_radiobox\_selected*

## DATA TYPES

```
wxRadioBox() = wx:wx_object()
```

## EXPORTS

```
new(Parent, Id, Label, Pos, Size, Choices) -> wxRadioBox()
```

Types:

Parent = wxWindow:wxWindow()\
 Id = integer()\
 Label = unicode:chardata()\
 Pos = {X :: integer(), Y :: integer()}\
 Size = {W :: integer(), H :: integer()}\
 Choices = \[unicode:chardata()\]\

```
new(Parent, Id, Label, Pos, Size, Choices, Options :: [Option]) ->
       wxRadioBox()
```

Types:

Parent = wxWindow:wxWindow()\
 Id = integer()\
 Label = unicode:chardata()\
 Pos = {X :: integer(), Y :: integer()}\
 Size = {W :: integer(), H :: integer()}\
 Choices = \[unicode:chardata()\]\
 Option = \
\
     {majorDim, integer()} \|\
\
     {style, integer()} \|\
\
     {val, wx:wx\_object()}\

Constructor, creating and showing a radiobox.

See: *create/8*, *wxValidator* (not implemented in wx)

```
destroy(This :: wxRadioBox()) -> ok
```

Destructor, destroying the radiobox item.

```
create(This, Parent, Id, Label, Pos, Size, Choices) -> boolean()
```

Types:

This = wxRadioBox()\
 Parent = wxWindow:wxWindow()\
 Id = integer()\
 Label = unicode:chardata()\
 Pos = {X :: integer(), Y :: integer()}\
 Size = {W :: integer(), H :: integer()}\
 Choices = \[unicode:chardata()\]\

```
create(This, Parent, Id, Label, Pos, Size, Choices,
       Options :: [Option]) ->
          boolean()
```

Types:

This = wxRadioBox()\
 Parent = wxWindow:wxWindow()\
 Id = integer()\
 Label = unicode:chardata()\
 Pos = {X :: integer(), Y :: integer()}\
 Size = {W :: integer(), H :: integer()}\
 Choices = \[unicode:chardata()\]\
 Option = \
\
     {majorDim, integer()} \|\
\
     {style, integer()} \|\
\
     {val, wx:wx\_object()}\

Creates the radiobox for two-step construction.

See *new/7* for further details.

```
enable(This) -> boolean()
```

Types:

This = wxRadioBox()\

```
enable(This, N) -> boolean()
```

```
enable(This, N :: [Option]) -> boolean()
```

Types:

This = wxRadioBox()\
 Option = {enable, boolean()}\

Enables or disables the radiobox.

See: *wxWindow:enable/2*

```
enable(This, N, Options :: [Option]) -> boolean()
```

Types:

This = wxRadioBox()\
 N = integer()\
 Option = {enable, boolean()}\

Enables or disables an individual button in the radiobox.

See: *wxWindow:enable/2*

```
getSelection(This) -> integer()
```

Types:

This = wxRadioBox()\

Returns the index of the selected item or *wxNOT\_FOUND* if no item is selected.

Return: The position of the current selection.

Remark: This method can be used with single selection list boxes only, you should use *wxListBox:getSelections/1* for the list boxes with wxLB\_MULTIPLE style.

See: *setSelection/2*, *wxControlWithItems:getStringSelection/1*

```
getString(This, N) -> unicode:charlist()
```

Types:

This = wxRadioBox()\
 N = integer()\

Returns the label of the item with the given index.

Return: The label of the item or an empty string if the position was invalid.

```
setSelection(This, N) -> ok
```

Types:

This = wxRadioBox()\
 N = integer()\

Sets the selection to the given item.

Notice that a radio box always has selection, so *n* must be valid here and passing *wxNOT\_FOUND* is not allowed.

```
show(This, Item) -> boolean()
```

Types:

This = wxRadioBox()\
 Item = integer()\

```
show(This, Item, Options :: [Option]) -> boolean()
```

Types:

This = wxRadioBox()\
 Item = integer()\
 Option = {show, boolean()}\

Shows or hides individual buttons.

Return: true if the item has been shown or hidden or false if nothing was done because it already was in the requested state.

See: *show/3*

```
getColumnCount(This) -> integer()
```

Types:

This = wxRadioBox()\

Returns the number of columns in the radiobox.

```
getItemHelpText(This, Item) -> unicode:charlist()
```

Types:

This = wxRadioBox()\
 Item = integer()\

Returns the helptext associated with the specified *item* if any or *wxEmptyString*.

See: *setItemHelpText/3*

```
getItemToolTip(This, Item) -> wxToolTip:wxToolTip()
```

Types:

This = wxRadioBox()\
 Item = integer()\

Returns the tooltip associated with the specified *item* if any or NULL.

See: *setItemToolTip/3*, *wxWindow:getToolTip/1*

```
getItemFromPoint(This, Pt) -> integer()
```

Types:

This = wxRadioBox()\
 Pt = {X :: integer(), Y :: integer()}\

Returns a radio box item under the point, a zero-based item index, or *wxNOT\_FOUND* if no item is under the point.

```
getRowCount(This) -> integer()
```

Types:

This = wxRadioBox()\

Returns the number of rows in the radiobox.

```
isItemEnabled(This, N) -> boolean()
```

Types:

This = wxRadioBox()\
 N = integer()\

Returns true if the item is enabled or false if it was disabled using *enable/3*.

This function is currently only implemented in wxMSW, wxGTK, wxQT and wxUniversal and always returns true in the other ports.

```
isItemShown(This, N) -> boolean()
```

Types:

This = wxRadioBox()\
 N = integer()\

Returns true if the item is currently shown or false if it was hidden using *show/3*.

Note that this function returns true for an item which hadn't been hidden even if the entire radiobox is not currently shown.

This function is currently only implemented in wxMSW, wxGTK, wxQT and wxUniversal and always returns true in the other ports.

```
setItemHelpText(This, Item, Helptext) -> ok
```

Types:

This = wxRadioBox()\
 Item = integer()\
 Helptext = unicode:chardata()\

Sets the helptext for an item.

Empty string erases any existing helptext.

See: *getItemHelpText/2*

```
setItemToolTip(This, Item, Text) -> ok
```

Types:

This = wxRadioBox()\
 Item = integer()\
 Text = unicode:chardata()\

Sets the tooltip text for the specified item in the radio group.

This function is currently only implemented in wxMSW and wxGTK2 and does nothing in the other ports.
