Struct TreeViewColumn 

pub struct TreeViewColumn { /* private fields */ }

The GtkTreeViewColumn object represents a visible column in a TreeView widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.

Please refer to the tree widget conceptual overview for an overview of all the objects and data types related to the tree widget and how they work together.

Properties

cell-area

The CellArea used to layout cell renderers for this column.

If no area is specified when creating the tree view column with TreeViewColumn::with_area() a horizontally oriented CellAreaBox will be used.

Implements

TreeViewColumnExt, [trait@glib::ObjectExt], BuildableExt, CellLayoutExt, BuildableExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl TreeViewColumn

pub const NONE: Option<&'static TreeViewColumn> = None

pub fn new() -> TreeViewColumn

Creates a new TreeViewColumn.

Returns

A newly created TreeViewColumn.

pub fn with_area(area: &impl IsA<CellArea>) -> TreeViewColumn

Creates a new TreeViewColumn using area to render its cells.

area

the CellArea that the newly created column should use to layout cells.

Returns

A newly created TreeViewColumn.

pub fn builder() -> TreeViewColumnBuilder

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

This method returns an instance of TreeViewColumnBuilder which can be used to create TreeViewColumn objects.

impl TreeViewColumn

pub fn with_attributes( title: &str, cell_renderer: &impl IsA<CellRenderer>, attributes: &[(&str, i32)], ) -> Self

enum { TEXT_COLUMN, COLOR_COLUMN, N_COLUMNS }; // … { GtkTreeViewColumn *column; GtkCellRenderer *renderer = gtk_cell_renderer_text_new ();

column = gtk_tree_view_column_new_with_attributes (“Title”, renderer, “text”, TEXT_COLUMN, “foreground”, COLOR_COLUMN, NULL); } ]|

title

The title to set the header to

cell

The CellRenderer

Returns

A newly created TreeViewColumn.

pub fn set_attributes( &self, cell_renderer: &impl IsA<CellRenderer>, attributes: &[(&str, i32)], )

Trait Implementations

impl Clone for TreeViewColumn

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for TreeViewColumn

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

Formats the value using the given formatter.

impl Default for TreeViewColumn

fn default() -> Self

Returns the “default value” for a type.

impl Eq for TreeViewColumn

impl HasParamSpec for TreeViewColumn

type ParamSpec = ParamSpecObject

type SetValue = TreeViewColumn

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, TreeViewColumn>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for TreeViewColumn

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IsA<Buildable> for TreeViewColumn

impl IsA<CellLayout> for TreeViewColumn

impl Ord for TreeViewColumn

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for TreeViewColumn

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for TreeViewColumn

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

Inequality operator !=.

impl<OT: ObjectType> PartialOrd<OT> for TreeViewColumn

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for TreeViewColumn

fn static_type() -> Type

Returns the type identifier of Self.
