ToggleButton#
Superclasses: Button, Widget, InitiallyUnowned, Object
Implemented Interfaces: Accessible, Actionable, Buildable, ConstraintTarget
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 new or
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 Button for more information).
The state of a GtkToggleButton can be set specifically using
set_active, and retrieved using
get_active.
To simply switch the state of a toggle button, use
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 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.
Accessibility#
GtkToggleButton uses the TOGGLE_BUTTON role.
Creating two#
static void
output_state (GtkToggleButton *source,
gpointer user_data)
{
g_print ("Toggle button "%s" is active: %s",
gtk_button_get_label (GTK_BUTTON (source)),
gtk_toggle_button_get_active (source) ? "Yes" : "No");
}
static void
make_toggles (void)
{
GtkWidget *window, *toggle1, *toggle2;
GtkWidget *box;
const char *text;
window = gtk_window_new ();
box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 12);
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_window_present (GTK_WINDOW (window));
}
Constructors#
- class ToggleButton
- classmethod new() → Widget#
Creates a new toggle button.
A widget should be packed into the button, as in
new.
- classmethod new_with_label(label: str) → Widget#
Creates a new toggle button with a text label.
- Parameters:
label – a string containing the message to be placed in the toggle button.
- classmethod new_with_mnemonic(label: str) → Widget#
Creates a new
GtkToggleButtoncontaining a label.The label will be created using
new_with_mnemonic, so underscores inlabelindicate the mnemonic for the button.- Parameters:
label – the text of the button, with an underscore in front of the mnemonic character
Methods#
- class ToggleButton
-
- get_active() → bool#
Queries a
GtkToggleButtonand returns its current state.Returns
Trueif the toggle button is pressed in andFalseif it is raised.
- set_active(is_active: bool) → None#
Sets the status of the toggle button.
Set to
Trueif you want theGtkToggleButtonto be “pressed in”, andFalseto raise it.If the status of the button changes, this action causes the
toggledsignal to be emitted.- Parameters:
is_active –
TrueorFalse.
- set_group(group: ToggleButton | None = None) → None#
Adds
selfto the group ofgroup.In a group of multiple toggle buttons, only one button can be active at a time.
Setting up groups in a cycle leads to undefined behavior.
Note that the same effect can be achieved via the
ActionableAPI, by using the same action with parameter type and state type ‘s’ for all buttons in the group, and giving each button its own target value.- Parameters:
group – another
GtkToggleButtonto form a group with
