Struct gtk4::CellRendererSpinner

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

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().

Implementations

impl CellRendererSpinner

pub fn new() -> CellRendererSpinner

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

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

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

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