Description

A GtkMenuShell is the abstract base class used to derive the GtkMenu and GtkMenuBar subclasses.

A GtkMenuShell is a container of GtkMenuItem objects arranged in a list which can be navigated, selected, and activated by the user to perform application functions. A GtkMenuItem can have a submenu associated with it, allowing for nested hierarchical menus.

Details

struct GtkMenuShell

struct GtkMenuShell;

The GtkMenuShell struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)

GList *children;

The list of GtkMenuItem objects contained by this GtkMenuShell.

gtk_menu_shell_append ()

void        gtk_menu_shell_append           (GtkMenuShell *menu_shell,
                                             GtkWidget *child);

Adds a new GtkMenuItem to the end of the menu shell's item list.

`menu_shell` :	a GtkMenuShell.
`child` :	The GtkMenuItem to add.

gtk_menu_shell_prepend ()

void        gtk_menu_shell_prepend          (GtkMenuShell *menu_shell,
                                             GtkWidget *child);

Adds a new GtkMenuItem to the beginning of the menu shell's item list.

`menu_shell` :	a GtkMenuShell.
`child` :	The GtkMenuItem to add.

gtk_menu_shell_insert ()

void        gtk_menu_shell_insert           (GtkMenuShell *menu_shell,
                                             GtkWidget *child,
                                             gint position);

Adds a new GtkMenuItem to the menu shell's item list at the position indicated by position.

`menu_shell` :	a GtkMenuShell.
`child` :	The GtkMenuItem to add.
`position` :	The position in the item list where `child` is added. Positions are numbered from 0 to n-1.

gtk_menu_shell_deactivate ()

void        gtk_menu_shell_deactivate       (GtkMenuShell *menu_shell);

Deactivates the menu shell. Typically this results in the menu shell being erased from the screen.

menu_shell : a GtkMenuShell.

gtk_menu_shell_select_item ()

void        gtk_menu_shell_select_item      (GtkMenuShell *menu_shell,
                                             GtkWidget *menu_item);

Selects the menu item from the menu shell.

`menu_shell` :	a GtkMenuShell.
`menu_item` :	The GtkMenuItem to select.

gtk_menu_shell_activate_item ()

void        gtk_menu_shell_activate_item    (GtkMenuShell *menu_shell,
                                             GtkWidget *menu_item,
                                             gboolean force_deactivate);

Activates the menu item within the menu shell.

`menu_shell` :	a GtkMenuShell.
`menu_item` :	The GtkMenuItem to activate.
`force_deactivate` :	If TRUE, force the deactivation of the menu shell after the menu item is activated.

enum GtkMenuDirectionType

typedef enum
{
  GTK_MENU_DIR_PARENT,
  GTK_MENU_DIR_CHILD,
  GTK_MENU_DIR_NEXT,
  GTK_MENU_DIR_PREV
} GtkMenuDirectionType;

An enumeration representing directional movements within a menu.

GTK_MENU_DIR_PARENT	To the parent menu shell.
GTK_MENU_DIR_CHILD	To the submenu, if any, associated with the item.
GTK_MENU_DIR_NEXT	To the next menu item.
GTK_MENU_DIR_PREV	To the previous menu item.

Signals

The "deactivate" signal

void        user_function                  (GtkMenuShell *menushell,
                                            gpointer user_data);

This signal is emitted when a menu shell is deactivated.

`menushell` :	the object which received the signal.
`user_data` :	user data set when the signal handler was connected.

The "selection-done" signal

void        user_function                  (GtkMenuShell *menushell,
                                            gpointer user_data);

This signal is emitted when a selection has been completed within a menu shell.

`menushell` :	the object which received the signal.
`user_data` :	user data set when the signal handler was connected.

The "move-current" signal

void        user_function                  (GtkMenuShell *menushell,
                                            GtkMenuDirectionType direction,
                                            gpointer user_data);

An action signal which moves the current menu item in the direction specified by direction.

`menushell` :	the object which received the signal.
`direction` :	the direction to move.
`user_data` :	user data set when the signal handler was connected.

The "activate-current" signal

void        user_function                  (GtkMenuShell *menushell,
                                            gboolean force_hide,
                                            gpointer user_data);

An action signal that activates the current menu item within the menu shell.

`menushell` :	the object which received the signal.
`force_hide` :	if TRUE, hide the menu after activating the menu item.
`user_data` :	user data set when the signal handler was connected.

The "cancel" signal

void        user_function                  (GtkMenuShell *menushell,
                                            gpointer user_data);

An action signal which cancels the selection within the menu shell. Causes the GtkMenuShell::selection-done signal to be emitted.

`menushell` :	the object which received the signal.
`user_data` :	user data set when the signal handler was connected.
