Struct gtk::ToggleButton [−][src]
pub struct ToggleButton(_);
Expand description
A ToggleButton is a Button which will remain “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 new() or
with_label(). If using the former, it is advisable to
pack a widget, (such as a Label and/or a Image), into the toggle
button’s container. (See Button for more information).
The state of a ToggleButton can be set specifically using
ToggleButtonExt::set_active(), and retrieved using
ToggleButtonExt::is_active().
To simply switch the state of a toggle button, use ToggleButtonExt::toggled().
CSS nodes
GtkToggleButton has a single CSS node with name button. To differentiate
it from a plain Button, it gets the .toggle style class.
Creating two ToggleButton widgets.
⚠️ The following code is in C ⚠️
static void output_state (GtkToggleButton *source, gpointer user_data) {
printf ("Active: %d\n", gtk_toggle_button_get_active (source));
}
void make_toggles (void) {
GtkWidget *window, *toggle1, *toggle2;
GtkWidget *box;
const char *text;
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 12);
text = "Hi, I’m a toggle button.";
toggle1 = gtk_toggle_button_new_with_label (text);
// Makes this toggle button invisible
gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle1),
TRUE);
g_signal_connect (toggle1, "toggled",
G_CALLBACK (output_state),
NULL);
gtk_container_add (GTK_CONTAINER (box), toggle1);
text = "Hi, I’m a toggle button.";
toggle2 = gtk_toggle_button_new_with_label (text);
gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle2),
FALSE);
g_signal_connect (toggle2, "toggled",
G_CALLBACK (output_state),
NULL);
gtk_container_add (GTK_CONTAINER (box), toggle2);
gtk_container_add (GTK_CONTAINER (window), box);
gtk_widget_show_all (window);
}

Implementations
Creates a new toggle button. A widget should be packed into the button, as in Button::new().
Returns
a new toggle button.
Creates a new ToggleButton containing a label. The label
will be created using Label::with_mnemonic(), so underscores
in label indicate the mnemonic for the button.
label
the text of the button, with an underscore in front of the mnemonic character
Returns
a new ToggleButton
Creates a new builder-pattern struct instance to construct ToggleButton objects.
This method returns an instance of ToggleButtonBuilder which can be used to create ToggleButton objects.
