Struct gtk4::CellAreaBox

#[repr(transparent)]
pub struct CellAreaBox { /* private fields */ }

A cell area that renders GtkCellRenderers into a row or a column

The CellAreaBox renders cell renderers into a row or a column depending on its Orientation.

GtkCellAreaBox uses a notion of packing. Packing refers to adding cell renderers with reference to a particular position in a CellAreaBox. There are two reference positions: the start and the end of the box. When the CellAreaBox is oriented in the Orientation::Vertical orientation, the start is defined as the top of the box and the end is defined as the bottom. In the Orientation::Horizontal orientation start is defined as the left side and the end is defined as the right side.

Alignments of CellRenderers rendered in adjacent rows can be configured by configuring the CellAreaBox align child cell property with gtk_cell_area_cell_set_property() or by specifying the “align” argument to gtk_cell_area_box_pack_start() and gtk_cell_area_box_pack_end().

Implementations

impl CellAreaBox

pub fn new() -> CellAreaBox

Creates a new CellAreaBox.

Returns

a newly created CellAreaBox

pub fn builder() -> CellAreaBoxBuilder

Creates a new builder-pattern struct instance to construct CellAreaBox objects.

This method returns an instance of CellAreaBoxBuilder which can be used to create CellAreaBox objects.

pub fn spacing(&self) -> i32

Gets the spacing added between cell renderers.

Returns

the space added between cell renderers in @self.

pub fn pack_end( &self, renderer: &impl IsA<CellRenderer>, expand: bool, align: bool, fixed: bool )

Adds @renderer to @self, packed with reference to the end of @self.

The @renderer is packed after (away from end of) any other CellRenderer packed with reference to the end of @self.

renderer

the CellRenderer to add

expand

whether @renderer should receive extra space when the area receives more than its natural size

align

whether @renderer should be aligned in adjacent rows

fixed

whether @renderer should have the same size in all rows

pub fn pack_start( &self, renderer: &impl IsA<CellRenderer>, expand: bool, align: bool, fixed: bool )

Adds @renderer to @self, packed with reference to the start of @self.

The @renderer is packed after any other CellRenderer packed with reference to the start of @self.

pub fn set_spacing(&self, spacing: i32)

Sets the spacing to add between cell renderers in @self.

the space to add between CellRenderers

pub fn connect_spacing_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

Trait Implementations

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CellAreaBox

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CellAreaBox

fn default() -> Self

Returns the “default value” for a type.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
