GtkToggleButton — Create buttons which retain their state

Object Hierarchy


Implemented Interfaces

GtkToggleButton implements GtkActivatable, AtkImplementorIface and GtkBuildable.


  "active"                   gboolean              : Read / Write
  "draw-indicator"           gboolean              : Read / Write
  "inconsistent"             gboolean              : Read / Write


  "toggled"                                        : Run First


A GtkToggleButton is a GtkButton 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 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 GtkPixmap), 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.

Example 15. Creating two GtkToggleButton widgets.

void make_toggles (void) {
   GtkWidget *dialog, *toggle1, *toggle2;
   dialog = gtk_dialog_new ();
   toggle1 = gtk_toggle_button_new_with_label ("Hi, i'm a toggle button.");
   /* 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_box_pack_start (GTK_BOX (GTK_DIALOG (dialog)->action_area),
                       toggle1, FALSE, FALSE, 2);
   toggle2 = gtk_toggle_button_new_with_label ("Hi, i'm another toggle button.");
   gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle2), FALSE);
   g_signal_connect (toggle2, "toggled",
                     G_CALLBACK (output_state), NULL);
   gtk_box_pack_start (GTK_BOX (GTK_DIALOG (dialog)->action_area),
                       toggle2, FALSE, FALSE, 2);
   gtk_widget_show_all (dialog);



typedef struct _GtkToggleButton GtkToggleButton;

The GtkToggleButton struct contains private data only, and should be manipulated using the functions below.

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().

Returns :

a new toggle button.

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.

label :

a string containing the message to be placed in the toggle button.

Returns :

a new toggle button.

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.

label :

the text of the button, with an underscore in front of the mnemonic character

Returns :

a new GtkToggleButton

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

toggle_button :

a GtkToggleButton

draw_indicator :

if TRUE, draw the button as a separate indicator and label; if FALSE, draw the button like a normal button

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().

toggle_button :

a GtkToggleButton

Returns :

TRUE if the togglebutton is drawn as a separate indicator and label.


#define	gtk_toggle_button_set_state		gtk_toggle_button_set_active


gtk_toggle_button_set_state is deprecated and should not be used in newly-written code. Use gtk_toggle_button_set_active() instead.

This is a deprecated macro, and is only maintained for compatibility reasons.

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.

toggle_button :

a GtkToggleButton.

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.

toggle_button :

a GtkToggleButton.

Returns :

a gboolean value.

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 to be emitted.

toggle_button :

a GtkToggleButton.

is_active :


gtk_toggle_button_get_inconsistent ()

gboolean            gtk_toggle_button_get_inconsistent  (GtkToggleButton *toggle_button);

Gets the value set by gtk_toggle_button_set_inconsistent().

toggle_button :

a GtkToggleButton

Returns :

TRUE if the button is displayed as inconsistent, FALSE otherwise

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.

toggle_button :

a GtkToggleButton

setting :

TRUE if state is inconsistent

Property Details

The "active" property

  "active"                   gboolean              : Read / Write

If the toggle button should be pressed in or not.

Default value: FALSE

The "draw-indicator" property

  "draw-indicator"           gboolean              : Read / Write

If the toggle part of the button is displayed.

Default value: FALSE

The "inconsistent" property

  "inconsistent"             gboolean              : Read / Write

Signal Details

The "toggled" signal

void                user_function                      (GtkToggleButton *togglebutton,
                                                        gpointer         user_data)         : Run First

Should be connected if you wish to perform an action whenever the GtkToggleButton's state is changed.

togglebutton :

the object which received the signal.

user_data :

user data set when the signal handler was connected.
