Class
GtkToggleButton
Description [src]
class Gtk.ToggleButton : Gtk.Button {
/* No available fields */
}
A GtkToggleButton
is a button which remains “pressed-in” when clicked.
Clicking again will cause the toggle button to return to its normal state.
A toggle button is created by calling either gtk_toggle_button_new()
or
gtk_toggle_button_new_with_label()
. If using the former, it is advisable
to pack a widget, (such as a GtkLabel
and/or a GtkImage
), into the toggle
button’s container. (See GtkButton
for more information).
The state of a GtkToggleButton
can be set specifically using
gtk_toggle_button_set_active()
, and retrieved using
gtk_toggle_button_get_active()
.
To simply switch the state of a toggle button, use
gtk_toggle_button_toggled()
.
Grouping
Toggle buttons can be grouped together, to form mutually exclusive groups - only one of the buttons can be toggled at a time, and toggling another one will switch the currently toggled one off.
To add a GtkToggleButton
to a group, use gtk_toggle_button_set_group()
.
CSS nodes
GtkToggleButton
has a single CSS node with name button. To differentiate
it from a plain GtkButton
, it gets the .toggle
style class.

widgets.

g_print ("Toggle button "%s" is active: %s",
gtk_button_get_label (GTK_BUTTON (source)),
gtk_toggle_button_get_active (source) ? "Yes" : "No");
}

text = "Hi, I’m toggle button one";
toggle1 = gtk_toggle_button_new_with_label (text);
g_signal_connect (toggle1, "toggled",
G_CALLBACK (output_state),
NULL);
gtk_box_append (GTK_BOX (box), toggle1);
text = "Hi, I’m toggle button two";
toggle2 = gtk_toggle_button_new_with_label (text);
g_signal_connect (toggle2, "toggled",
G_CALLBACK (output_state),
NULL);
gtk_box_append (GTK_BOX (box), toggle2);
gtk_window_set_child (GTK_WINDOW (window), box);
gtk_widget_show (window);
}
