{pos, {X :: integer(), Y :: integer()}} |
{size, {W :: integer(), H :: integer()}} |
{style, integer()} |

####
create(This, Parent, Id, Label, Options :: [Option]) -> boolean()

### Types

This = wxCheckBox()
Parent = wxWindow:wxWindow()
Id = integer()
Label = unicode:chardata()
Option =
{pos, {X :: integer(), Y :: integer()}} |
{size, {W :: integer(), H :: integer()}} |
{style, integer()} |
{validator, wx:wx_object()}

See new/4 for details.

####
getValue(This) -> boolean()

### Types

This = wxCheckBox()

Gets the state of a 2-state checkbox.

Return: Returns true if it is checked, false otherwise.

####
get3StateValue(This) -> wx:wx_enum()

### Types

This = wxCheckBox()

Gets the state of a 3-state checkbox.

Asserts when the function is used with a 2-state checkbox.

####
is3rdStateAllowedForUser(This) -> boolean()

### Types

This = wxCheckBox()

Returns whether or not the user can set the checkbox to the third state.

Return: true if the user can set the third state of this checkbox, false if it can only be set programmatically or if it's a 2-state checkbox.

####
is3State(This) -> boolean()

### Types

This = wxCheckBox()

Returns whether or not the checkbox is a 3-state checkbox.

Return: true if this checkbox is a 3-state checkbox, false if it's a 2-state checkbox.

####
isChecked(This) -> boolean()

### Types

This = wxCheckBox()

This is just a maybe more readable synonym for getValue/1: just as the latter, it returns true if the checkbox is checked and false otherwise.

####
setValue(This, State) -> ok

### Types

This = wxCheckBox()
State = boolean()

Sets the checkbox to the given state.

This does not cause a wxEVT_CHECKBOX event to get emitted.

####
set3StateValue(This, State) -> ok

### Types

This = wxCheckBox()
State = wx:wx_enum()

Sets the checkbox to the given state.

This does not cause a wxEVT_CHECKBOX event to get emitted.
