Implemented Interfaces
GtkCheckMenuItem implements AtkImplementorIface, GtkBuildable, GtkActivatable and GtkActionable.
Description
A GtkCheckMenuItem is a menu item that maintains the state of a boolean value in addition to a GtkMenuItem usual role in activating application code.
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.
Functions
gtk_check_menu_item_new ()
GtkWidget *
gtk_check_menu_item_new (void
);
Creates 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.
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.
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()
.
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.
gtk_check_menu_item_toggled ()
void
gtk_check_menu_item_toggled (GtkCheckMenuItem *check_menu_item
);
Emits the “toggled” signal.
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()
.
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.
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
Since 2.4
gtk_check_menu_item_get_draw_as_radio ()
gboolean
gtk_check_menu_item_get_draw_as_radio (GtkCheckMenuItem *check_menu_item
);
Returns whether check_menu_item
looks like a GtkRadioMenuItem
Since 2.4
Types and Values
struct GtkCheckMenuItemClass
struct GtkCheckMenuItemClass { GtkMenuItemClass parent_class; void (* toggled) (GtkCheckMenuItem *check_menu_item); void (* draw_indicator) (GtkCheckMenuItem *check_menu_item, cairo_t *cr); };
Members
GtkMenuItemClass |
The parent class. |
|
Signal emitted when the state of the check box is changed. |
||
Called to draw the check indicator. |
Property Details
The “active”
property
“active” gboolean
Whether the menu item is checked.
Flags: Read / Write
Default value: FALSE
The “draw-as-radio”
property
“draw-as-radio” gboolean
Whether the menu item looks like a radio menu item.
Flags: Read / Write
Default value: FALSE
The “inconsistent”
property
“inconsistent” gboolean
Whether to display an "inconsistent" state.
Flags: Read / Write
Default value: FALSE
Style Property Details
The “indicator-size”
style property
“indicator-size” gint
Size of check or radio indicator.
Flags: Read
Allowed values: >= 0
Default value: 16
Signal Details
The “toggled”
signal
void user_function (GtkCheckMenuItem *checkmenuitem, gpointer user_data)
This signal is emitted when the state of the check box is changed.
A signal handler can use gtk_check_menu_item_get_active()
to discover the new state.
Parameters
checkmenuitem |
the object which received the signal. |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run First
