Description

A check box indicating the state of the boolean value is displayed at the left side of the GtkMenuItem. Activating the GtkMenuItem toggles the value.

GtkCheckMenuItem has a main CSS node with name menuitem, and a subnode with name check, which gets the .left or .right style class.
Functions
gtk_check_menu_item_new ()
GtkWidget *
gtk_check_menu_item_new (void
);
Creates a new GtkCheckMenuItem.
Returns
a new GtkCheckMenuItem.
gtk_check_menu_item_new_with_label ()
GtkWidget *
gtk_check_menu_item_new_with_label (const gchar *label
);
Creates a new GtkCheckMenuItem with a label.
Parameters
label | the string to use for the label. |
Returns
a new GtkCheckMenuItem.
gtk_check_menu_item_new_with_mnemonic ()
GtkWidget *
gtk_check_menu_item_new_with_mnemonic (const gchar *label
);
Creates a new GtkCheckMenuItem containing a label. The label will be created using gtk_label_new_with_mnemonic()
, so underscores in label
indicate the mnemonic for the menu item.
Parameters
label | The text of the button, with an underscore in front of the character |
Returns
a new GtkCheckMenuItem
gtk_check_menu_item_get_active ()
gboolean
gtk_check_menu_item_get_active (GtkCheckMenuItem *check_menu_item
);
Returns whether the check menu item is active. See gtk_check_menu_item_set_active()
.
Parameters
check_menu_item |
Returns
TRUE
if the menu item is checked.
gtk_check_menu_item_set_active ()
void gtk_check_menu_item_set_active (GtkCheckMenuItem *check_menu_item
,gboolean is_active
);
Sets the active state of the menu item’s check box.
Parameters
check_menu_item | ||
is_active | boolean value indicating whether the check box is active. |
gtk_check_menu_item_toggled ()
void
gtk_check_menu_item_toggled (GtkCheckMenuItem *check_menu_item
);
Emits the “toggled” signal.
Parameters
check_menu_item |
gtk_check_menu_item_get_inconsistent ()
gboolean
gtk_check_menu_item_get_inconsistent (GtkCheckMenuItem *check_menu_item
);
Retrieves the value set by gtk_check_menu_item_set_inconsistent()
.
Parameters
check_menu_item |
Returns
TRUE
if inconsistent
gtk_check_menu_item_set_inconsistent ()
void gtk_check_menu_item_set_inconsistent (GtkCheckMenuItem *check_menu_item
,gboolean setting
);
If the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a boolean setting, and the current values in that range are inconsistent, you may want to display the check in an “in between” state. This function turns on “in between” display. Normally you would turn off the inconsistent state again if the user explicitly selects a setting. This has to be done manually, gtk_check_menu_item_set_inconsistent()
only affects visual appearance, it doesn’t affect the semantics of the widget.
Parameters
check_menu_item | ||
setting |
|
gtk_check_menu_item_set_draw_as_radio ()
void gtk_check_menu_item_set_draw_as_radio (GtkCheckMenuItem *check_menu_item
,gboolean draw_as_radio
);
Sets whether check_menu_item
is drawn like a GtkRadioMenuItem
Parameters
check_menu_item | ||
draw_as_radio | whether |

looks like a GtkRadioMenuItem
Parameters
check_menu_item |
Returns
Whether check_menu_item
looks like a GtkRadioMenuItem
Since: 2.4
