wxCheckBox - Functions for wxCheckBox class

A checkbox is a labelled box which by default is either on (checkmark is visible) or off (no checkmark). Optionally (when the wxCHK_3STATE style flag is set) it can have a third state, called the mixed or undetermined state. Often this is used as a "Does Not Apply" state.

Styles

This class supports the following styles:

See: wxRadioButton, wxCommandEvent

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

wxWidgets docs: wxCheckBox

Event types emitted from this class: command_checkbox_clicked

wxCheckBox() = wx:wx_object()





new() -> wxCheckBox()

Default constructor.

See: create/5, wxValidator (not implemented in wx)


new(Parent, Id, Label) -> wxCheckBox()

Types:

Parent = wxWindow:wxWindow()
Id = integer()
Label = unicode:chardata() 


new(Parent, Id, Label, Options :: [Option]) -> wxCheckBox()

Types:

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()}

Constructor, creating and showing a checkbox.

See: create/5, wxValidator (not implemented in wx)


destroy(This :: wxCheckBox()) -> ok

Destructor, destroying the checkbox.


create(This, Parent, Id, Label) -> boolean()

Types:

This = wxCheckBox()
Parent = wxWindow:wxWindow()
Id = integer()
Label = unicode:chardata() 


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()}

Creates the checkbox for two-step construction.

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.

Asserts when the checkbox is a 2-state checkbox and setting the state to wxCHK_UNDETERMINED.
