attr type

type: 'Icon'

Type: 'Icon'

method get_class

function get_class() -> table<number, string>

Get the css classes as an array of strings.

Returns:

• table<number, string>

method get_file

function get_file() -> nil

Gets the path to the file the icon is displaying.

Returns:

• nil

method get_file_reactive

function get_file_reactive() -> string

Fetches the reactive file for the icon.

Returns:

• string

method get_halign

function get_halign() -> 'Baseline'|'Center'|'End'|'Fill'|'Start'...(+1)

Gets the horizontal alignment of widget.

return #1:
    | 'Fill'
    | 'Start'
    | 'End'
    | 'Center'
    | 'Baseline'

Returns:

• 'Baseline'|'Center'|'End'|'Fill'|'Start'...(+1)

method get_height

function get_height() -> integer

Returns the content height of the widget.

To learn more about widget sizes, see the coordinate system overview.

View gtk4 documentation

Returns:

• integer

method get_height_request

function get_height_request() -> integer

Gets the height request that was explicitly set for the widget using set_height_request or set_size_request.

A value of -1 stored in height indicates that it has not been set explicitly and the natural requisition of the widget will be used instead. To get the height a widget will actually request, call measure_height instead of this function.

See also: get_width_request, get_size_request.

View gtk4 documentation

Returns:

• integer

method get_hexpand

function get_hexpand() -> boolean

Gets whether the widget would like any available extra horizontal space.

View gtk4 documentation

Returns:

• boolean

method get_size_request

function get_size_request() -> [integer, integer]

Gets the size request that was explicitly set for the widget using set_size_request.

A value of -1 stored in width or height indicates that that dimension has not been set explicitly and the natural requisition of the widget will be used instead. To get the size a widget will actually request, call measure instead of this function.

See also: get_width_request, get_height_request.

View gtk4 documentation

Returns:

• [integer, integer]

method get_type

function get_type() -> 'Icon'

Get the type of widget

return #1:
    | 'Icon'

Returns:

• 'Icon'

method get_valign

function get_valign() -> 'Baseline'|'Center'|'End'|'Fill'|'Start'...(+1)

Gets the vertical alignment of widget.

View gtk4 documentation

return #1:
    | 'Fill'
    | 'Start'
    | 'End'
    | 'Center'
    | 'Baseline'

Returns:

• 'Baseline'|'Center'|'End'|'Fill'|'Start'...(+1)

method get_vexpand

function get_vexpand() -> boolean

Gets whether the widget would like any available extra vertical space.

View gtk4 documentation

Returns:

• boolean

method get_width

function get_width() -> integer

Returns the content width of the widget.

To learn more about widget sizes, see the coordinate system overview.

View gtk4 documentation

Returns:

• integer

method get_width_request

function get_width_request() -> integer

Gets the width request that was explicitly set for the widget using set_width_request or set_size_request.

A value of -1 stored in width indicates that it has not been set explicitly and the natural requisition of the widget will be used instead. To get the width a widget will actually request, call measure_width instead of this function.

See also: get_height_request, get_size_request.

Returns:

• integer

method set_class

function set_class(...string) -> nil

Set the css classes either as a space delimited string or array of strings.

Returns:

• nil

method set_file

function set_file(string: string) -> string

Sets the icon from from the a path for displaying.

method set_halign

function set_halign(halign: 'Baseline'|'Center'|'End'|'Fill'|'Start'...(+1)) -> nil

Sets the horizontal alignment of widget.

View gtk4 documentation

halign:
    | 'Fill'
    | 'Start'
    | 'End'
    | 'Center'
    | 'Baseline'

Parameters:

• halign

  ('Baseline'|'Center'|'End'|'Fill'|'Start'...(+1))

Returns:

• nil

method set_height_request

function set_height_request(height: integer?) -> nil

Sets the minimum height of a widget.

That is, the widget’s size request will be at least height. You can use this function to force a widget to be taller than it normally would be.

If the height request in a given direction is -1 (unset), then the “natural” height request of the widget will be used instead.

See also: set_width_request, set_size_request.

View gtk4 documentation

Parameters:

• height

  (integer?)

Returns:

• nil

method set_hexpand

function set_hexpand(hexpand: boolean) -> nil

Sets whether the widget would like any available extra horizontal space.

View gtk4 documentation

Parameters:

• hexpand

  (boolean)

Returns:

• nil

method set_size_request

function set_size_request(size: [integer?, integer?]) -> nil

Sets the minimum size of a widget.

That is, the widget’s size request will be at least width by height. You can use this function to force a widget to be larger than it normally would be.

If the size request in a given direction is -1 (unset), then the “natural” size request of the widget will be used instead.

See also: set_width_request, set_height_request.

Parameters:

• size

  ([integer?, integer?])

Returns:

• nil

method set_valign

function set_valign(valign: 'Baseline'|'Center'|'End'|'Fill'|'Start'...(+1)) -> nil

Sets the vertical alignment of widget.

    | 'Center'
    | 'Baseline'

Parameters:

• valign

Returns:

• nil

method set_vexpand

function set_vexpand(vexpand: boolean) -> nil

Sets whether the widget would like any available extra vertical space.

View gtk4 documentation

Parameters:

• vexpand

  (boolean)

Returns:

• nil

method set_width_request

function set_width_request(width: integer?) -> nil

Sets the minimum width of a widget.

That is, the widget’s size request will be at least width. You can use this function to force a widget to be wider than it normally would be.

If the width request in a given direction is -1 (unset), then the “natural” width request of the widget will be used instead.
