Module Summary

Functions for wxCheckBox class

Description

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

Events

Event types emitted from this class: command_checkbox_clicked

new() -> wxCheckBox()

Default constructor.

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

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

Types

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

Types

Id = integer()
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

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

Types

Id = integer()
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

Gets the state of a 2-state checkbox.

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

get3StateValue(This) -> wx:wx_enum()

Types

Gets the state of a 3-state checkbox.

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

is3rdStateAllowedForUser(This) -> boolean()

Types

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

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 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

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

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.
