Struct libpanel::Grid

pub struct Grid { /* private fields */ }

The Grid is a widget used to layout the dock item in the center area.

Signals

create-frame

The “create-frame” signal is used to create a new frame within the grid.

Consumers of this signal are required to return an unrooted Frame from this signal. The first signal handler wins.

Widget

destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See [methodGtk.keynav_failed] for details.

map

Emitted when widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with [propertyGtk:visible]) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of [signalGtk::unmap].

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates widget if group_cycling is false, or just makes widget grab focus if group_cycling is true.

move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are <kbd>Tab</kbd> to move forward, and <kbd>Shift</kbd>+<kbd>Tab</kbd> to move backward.

Action

query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the [propertyGtk:has-tooltip] property is true and the hover timeout has expired with the cursor hovering “above” widget; or emitted when widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for widget. If this is the case true should be returned, false otherwise. Note that if keyboard_mode is true, the values of x and y are undefined and should not be used.

The signal handler is free to manipulate tooltip with the therefore destined function calls.

realize

Emitted when widget is associated with a GdkSurface.

This means that [methodGtk.realize] has been called or the widget has been mapped (that is, it is going to be drawn).

show

Emitted when widget is shown.

state-flags-changed

Emitted when the widget state changes.

See [methodGtk.get_state_flags].

unmap

Emitted when widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

unrealize

Emitted when the GdkSurface associated with widget is destroyed.

This means that [methodGtk.unrealize] has been called or the widget has been unmapped (that is, it is going to be hidden).

Implements

PanelGridExt, gtk::prelude::WidgetExt, [trait@glib::ObjectExt], gtk::prelude::AccessibleExt, gtk::prelude::BuildableExt, gtk::prelude::ConstraintTargetExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl Grid

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

pub fn new() -> Grid

Creates a new Grid.

Returns

a newly created Grid

pub fn builder() -> GridBuilder

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

This method returns an instance of GridBuilder which can be used to create Grid objects.

Trait Implementations

impl Clone for Grid

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 Grid

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

Formats the value using the given formatter.

impl Default for Grid

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for Grid

type ParamSpec = ParamSpecObject

type SetValue = Grid

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Grid

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<T: PanelGridImpl> IsSubclassable<T> for Grid

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for Grid

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 + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for Grid

type Parent = Widget

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

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

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

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

impl StaticType for Grid

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Grid

impl IsA<Accessible> for Grid

impl IsA<Buildable> for Grid

impl IsA<ConstraintTarget> for Grid

impl IsA<Widget> for Grid
