The Gtk.Spinner displays an icon-size spinning animation. It is often used as an alternative to a GtkProgressBar for displaying an indefinite activity. We can use Gtk.Spinner.start() to start and Gtk.Spinner.stop() to stop the animation.
Example :
Python3
import gi gi.require_version( "Gtk" , "3.0" ) from gi.repository import Gtk class SpinnerAnimation(Gtk.Window): def __init__( self ): Gtk.Window.__init__( self , title = "GFG" ) self .set_border_width( 3 ) self .connect( "destroy" , Gtk.main_quit) self .button = Gtk.ToggleButton(label = "Start Spinning" ) self .button.connect( "toggled" , self .on_button_toggled) self .button.set_active( False ) self .spinner = Gtk.Spinner() self .grid = Gtk.Grid() self .grid.add( self .button) self .grid.attach_next_to( self .spinner, self .button, Gtk.PositionType.BOTTOM, 1 , 2 ) self .grid.set_row_homogeneous( True ) self .add( self .grid) self .show_all() def on_button_toggled( self , button): if button.get_active(): self .spinner.start() self .button.set_label( "Stop Spinning" ) else : self .spinner.stop() self .button.set_label( "Start Spinning" ) myspinner = SpinnerAnimation() Gtk.main() |
