Struct gtk4::CellRendererSpinner

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

List views use widgets to display their contents. You should use Spinner instead Renders a spinning animation in a cell

CellRendererSpinner renders a spinning animation in a cell, very similar to Spinner. It can often be used as an alternative to a CellRendererProgress for displaying indefinite activity, instead of actual progress.

To start the animation in a cell, set the GtkCellRendererSpinner:active property to true and increment the GtkCellRendererSpinner:pulse property at regular intervals. The usual way to set the cell renderer properties for each cell is to bind them to columns in your tree model using e.g. gtk_tree_view_column_add_attribute().

Properties

active

Readable | Writeable

pulse

Pulse of the spinner. Increment this value to draw the next frame of the spinner animation. Usually, you would update this value in a timeout.

By default, the Spinner widget draws one full cycle of the animation, consisting of 12 frames, in 750 milliseconds.

size

The IconSize value that specifies the size of the rendered spinner.

Implementations

impl CellRendererSpinner

pub fn new() -> CellRendererSpinner

Returns a new cell renderer which will show a spinner to indicate activity.

Deprecated since 4.10

Returns

a new CellRenderer

pub fn builder() -> CellRendererSpinnerBuilder

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

This method returns an instance of CellRendererSpinnerBuilder which can be used to create CellRendererSpinner objects.

pub fn is_active(&self) -> bool

pub fn set_active(&self, active: bool)

pub fn pulse(&self) -> u32

Pulse of the spinner. Increment this value to draw the next frame of the spinner animation. Usually, you would update this value in a timeout.

By default, the Spinner widget draws one full cycle of the animation, consisting of 12 frames, in 750 milliseconds.

pub fn set_pulse(&self, pulse: u32)

Pulse of the spinner. Increment this value to draw the next frame of the spinner animation. Usually, you would update this value in a timeout.

By default, the Spinner widget draws one full cycle of the animation, consisting of 12 frames, in 750 milliseconds.

pub fn size(&self) -> IconSize

The IconSize value that specifies the size of the rendered spinner.

pub fn set_size(&self, size: IconSize)

The IconSize value that specifies the size of the rendered spinner.

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

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

Formats the value using the given formatter.

impl Default for CellRendererSpinner

fn default() -> Self

Returns the “default value” for a type.
