Select the first visible or selectable child of the menu shell; don't select tearoff items unless the only item is a tearoff item.

Parameters

menu_shell

a GtkMenuShell

 

search_sensitive

if TRUE, search for the first selectable menu item, otherwise select nothing if the first item isn't sensitive. This should be FALSE if the menu is being popped up initially.

gtk_menu_shell_set_take_focus ()

void
gtk_menu_shell_set_take_focus (GtkMenuShell *menu_shell,
                               gboolean take_focus);

If take_focus is TRUE (the default) the menu shell will take the keyboard focus so that it will receive all keyboard events which is needed to enable keyboard navigation in menus.

Setting take_focus to FALSE is useful only for special applications like virtual keyboard implementations which should not take keyboard focus.

The take_focus state of a menu or menu bar is automatically propagated to submenus whenever a submenu is popped up, so you don't have to worry about recursively setting it for your entire menu hierarchy. Only when programmatically picking a submenu and popping it up manually, the take_focus property of the submenu needs to be set explicitely.

Note that setting it to FALSE has side-effects:

If the focus is in some other app, it keeps the focus and keynav in the menu doesn't work. Consequently, keynav on the menu will only work if the focus is on some toplevel owned by the onscreen keyboard.

To avoid confusing the user, menus with take_focus set to FALSE should not display mnemonics or accelerators, since it cannot be guaranteed that they will work.

Property Details

The “take-focus” property

  “take-focus”               gboolean

A boolean that determines whether the menu and its submenus grab the keyboard focus. See gtk_menu_shell_set_take_focus() and gtk_menu_shell_get_take_focus().

Owner: GtkMenuShell

Flags: Read / Write

Default value: TRUE

Since: 2.8

Signal Details

The “activate-current” signal

void
user_function (GtkMenuShell *menushell,
               gboolean      arg1,
               gpointer      user_data)

Flags: Action


The “cancel” signal

void
user_function (GtkMenuShell *menushell,
               gpointer      user_data)

Flags: Action


The “cycle-focus” signal

void
user_function (GtkMenuShell    *menushell,
               GtkDirectionType arg1,
               gpointer         user_data)

Flags: Action


The “deactivate” signal

void
user_function (GtkMenuShell *menushell,
               gpointer      user_data)

Flags: Run First


The “insert” signal

void
user_function (GtkMenuShell *menu_shell,
               GtkWidget    *child,
               int           position,
               gpointer      user_data)

The ::insert signal is emitted when a new GtkMenuItem is added to a GtkMenuShell. A separate signal is used instead of GtkContainer::add because of the need for an additional position parameter.

The inverse of this signal is the GtkContainer::remove signal.

Parameters

menu_shell

the object on which the signal is emitted

 

child

the GtkMenuItem that is being inserted

 

position

the position at which the insert occurs

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First

Since: 2.24.15


The “move-current” signal

void
user_function (GtkMenuShell        *menushell,
               GtkMenuDirectionType arg1,
               gpointer             user_data)

Flags: Action


The “move-selected” signal

gboolean
user_function (GtkMenuShell *menu_shell,
               int           distance,
               gpointer      user_data)

The ::move-selected signal is emitted to move the selection to another item.

Parameters

menu_shell

the object on which the signal is emitted

 

distance

+1 to move to the next item, -1 to move to the previous

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop the signal emission, FALSE to continue

Flags: Run Last

Since: 2.12


The “selection-done” signal

void
user_function (GtkMenuShell *menushell,
               gpointer      user_data)

Flags: Run First
