GtkToggleButton

CSS nodes

GtkToggleButton has a single CSS node with name button. To differentiate it from a plain GtkButton, it gets the .toggle style class.

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);
}

gtk_toggle_button_new ()

GtkWidget *
gtk_toggle_button_new (void);

Creates a new toggle button. A widget should be packed into the button, as in gtk_button_new().

gtk_toggle_button_new_with_label ()

GtkWidget *
gtk_toggle_button_new_with_label (const gchar *label);

Creates a new toggle button with a text label.

gtk_toggle_button_new_with_mnemonic ()

GtkWidget *
gtk_toggle_button_new_with_mnemonic (const gchar *label);

Creates a new GtkToggleButton containing a label. The label will be created using gtk_label_new_with_mnemonic(), so underscores in label indicate the mnemonic for the button.

gtk_toggle_button_set_mode ()

void
gtk_toggle_button_set_mode (GtkToggleButton *toggle_button,
                            gboolean draw_indicator);

Sets whether the button is displayed as a separate indicator and label. You can call this function on a checkbutton or a radiobutton with draw_indicator = FALSE to make the button look like a normal button.

This can be used to create linked strip of buttons that work like a GtkStackSwitcher.

This function only affects instances of classes like GtkCheckButton and GtkRadioButton that derive from GtkToggleButton, not instances of GtkToggleButton itself.

gtk_toggle_button_get_mode ()

gboolean
gtk_toggle_button_get_mode (GtkToggleButton *toggle_button);

Retrieves whether the button is displayed as a separate indicator and label. See gtk_toggle_button_set_mode().

gtk_toggle_button_toggled ()

void
gtk_toggle_button_toggled (GtkToggleButton *toggle_button);

Emits the “toggled” signal on the GtkToggleButton. There is no good reason for an application ever to call this function.

gtk_toggle_button_get_active ()

gboolean
gtk_toggle_button_get_active (GtkToggleButton *toggle_button);

Queries a GtkToggleButton and returns its current state. Returns TRUE if the toggle button is pressed in and FALSE if it is raised.

gtk_toggle_button_set_active ()

void
gtk_toggle_button_set_active (GtkToggleButton *toggle_button,
                              gboolean is_active);

Sets the status of the toggle button. Set to TRUE if you want the GtkToggleButton to be “pressed in”, and FALSE to raise it. This action causes the “toggled” signal and the “clicked” signal to be emitted.

gtk_toggle_button_get_inconsistent ()

gboolean
gtk_toggle_button_get_inconsistent (GtkToggleButton *toggle_button);

Gets the value set by gtk_toggle_button_set_inconsistent().

gtk_toggle_button_set_inconsistent ()

void
gtk_toggle_button_set_inconsistent (GtkToggleButton *toggle_button,
                                    gboolean setting);

If the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a toggle button, and the current values in that range are inconsistent, you may want to display the toggle in an “in between” state. This function turns on “in between” display. Normally you would turn off the inconsistent state again if the user toggles the toggle button. This has to be done manually, gtk_toggle_button_set_inconsistent() only affects visual appearance, it doesn’t affect the semantics of the button.

struct GtkToggleButton

struct GtkToggleButton;

The “active” property

  “active”                   gboolean

If the toggle button should be pressed in.

The “draw-indicator” property

  “draw-indicator”           gboolean

If the toggle part of the button is displayed.

Owner: GtkToggleButton

Flags: Read / Write

Default value: FALSE

The “toggled” signal

void
user_function (GtkToggleButton *togglebutton,
               gpointer         user_data)
