GtkCellRendererSpinner renders a spinning animation in a cell, very similar to GtkSpinner. It can often be used as an alternative to a GtkCellRendererProgress 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. gtk_tree_view_column_add_attribute().


gtk_cell_renderer_spinner_new ()

Property Details

The “active” property

  “active”                   gboolean

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

Flags: Read / Write

Default value: FALSE

The “pulse” property

  “pulse”                    guint

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

  “size”                     GtkIconSize
