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() |
