Renders a spinning animation in a cell

  • Module available since Gtk+ version 2.20



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 active property to True and increment the 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. treeViewColumnAddAttribute.

Class Hierarchy



cellRendererSpinnerNew :: IO CellRendererSpinnerSource

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

  • Available since Gtk+ version 2.20


cellRendererSpinnerActive :: CellRendererSpinnerClass self => Attr self BoolSource

Whether the spinner is active (ie. shown) in the cell.

Default value: False

  • Available since Gtk+ version 2.20

cellRendererSpinnerPulse :: CellRendererSpinnerClass self => Attr self IntSource

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.

The Spinner widget draws one full cycle of the animation per second by default. You can learn about the number of frames used by the theme by looking at the numSteps style property and the duration of the cycle by looking at cycleDuration.

Default value: 0

  • Available since Gtk+ version 2.20

cellRendererSpinnerSize :: CellRendererSpinnerClass self => Attr self IconSizeSource

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

Default value: IconSizeMenu
