Detail
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
.

Types
class CellRendererClass o => CellRendererSpinnerClass o Source
castToCellRendererSpinner :: GObjectClass obj => obj -> CellRendererSpinner Source
Constructors
cellRendererSpinnerNew :: IO CellRendererSpinner Source
Returns a new cell renderer which will show a spinner to indicate activity.
- Available since Gtk+ version 2.20
Attributes
cellRendererSpinnerActive :: CellRendererSpinnerClass self => Attr self Bool Source
Whether the spinner is active (ie. shown) in the cell.
Default value: False
- Available since Gtk+ version 2.20
cellRendererSpinnerPulse :: CellRendererSpinnerClass self => Attr self Int Source
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 IconSize Source
The IconSize
value that specifies the size of the rendered spinner.
Default value: IconSizeMenu
- Available since Gtk+ version 2.20
