public class Menu
extends MenuModel

GMenu is a simple implementation of MenuModel. You populate a GMenu by adding MenuItem instances to it.

There are some convenience functions to allow you to directly add items (avoiding MenuItem) for the common cases. To add a regular item, use insert(int, java.lang.String, java.lang.String). To add a section, use insertSection(int, java.lang.String, org.gnome.gio.MenuModel). To add a submenu, use insertSubmenu(int, java.lang.String, org.gnome.gio.MenuModel).

Constructor Details

Menu

public Menu(MemorySegment address)

Create a Menu proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Menu

public Menu()

Creates a new GMenu.

The new menu has no items.

Method Details

getType

public static Type getType()

Get the GType of the Menu class

Returns:

the GType

asParent

protected Menu asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class MenuModel

append

public void append(@Nullable
 @Nullable String label,
 @Nullable
 @Nullable String detailedAction)

Convenience function for appending a normal menu item to the end of this Menu. Combine g_menu_item_new() and g_menu_insert_item() for a more flexible alternative.

Parameters:

label - the section label, or null

detailedAction - the detailed action string, or null

appendItem

public void appendItem(MenuItem item)

Appends item to the end of this Menu.

See g_menu_insert_item() for more information.

Parameters:

item - a GMenuItem to append

appendSection

public void appendSection(@Nullable
 @Nullable String label,
 MenuModel section)

Convenience function for appending a section menu item to the end of this Menu. Combine g_menu_item_new_section() and g_menu_insert_item() for a more flexible alternative.

Parameters:

label - the section label, or null

section - a GMenuModel with the items of the section

appendSubmenu

public void appendSubmenu(@Nullable
 @Nullable String label,
 MenuModel submenu)

Convenience function for appending a submenu menu item to the end of this Menu. Combine g_menu_item_new_submenu() and g_menu_insert_item() for a more flexible alternative.

Parameters:

label - the section label, or null

submenu - a GMenuModel with the items of the submenu

freeze

public void freeze()

Marks this Menu as frozen.

After the menu is frozen, it is an error to attempt to make any changes to it. In effect this means that the GMenu API must no longer be used.

This function causes g_menu_model_is_mutable() to begin returning false, which has some positive performance implications.

insert

public void insert(int position,
 @Nullable
 @Nullable String label,
 @Nullable
 @Nullable String detailedAction)

Convenience function for inserting a normal menu item into this Menu. Combine g_menu_item_new() and g_menu_insert_item() for a more flexible alternative.

Parameters:

position - the position at which to insert the item

label - the section label, or null

detailedAction - the detailed action string, or null

insertItem

public void insertItem(int position,
 MenuItem item)

Inserts item into this Menu.

The "insertion" is actually done by copying all of the attribute and link values of item and using them to form a new item within this Menu. As such, item itself is not really inserted, but rather, a menu item that is exactly the same as the one presently described by item.

This means that item is essentially useless after the insertion occurs. Any changes you make to it are ignored unless it is inserted again (at which point its updated values will be copied).

You should probably just free item once you're done.

There are many convenience functions to take care of common cases. See g_menu_insert(), g_menu_insert_section() and g_menu_insert_submenu() as well as "prepend" and "append" variants of each of these functions.

Parameters:

position - the position at which to insert the item

item - the GMenuItem to insert

insertSection

public void insertSection(int position,
 @Nullable
 @Nullable String label,
 MenuModel section)

Convenience function for inserting a section menu item into this Menu. Combine g_menu_item_new_section() and g_menu_insert_item() for a more flexible alternative.

Parameters:

position - the position at which to insert the item

label - the section label, or null

section - a GMenuModel with the items of the section

insertSubmenu

public void insertSubmenu(int position,
 @Nullable
 @Nullable String label,
 MenuModel submenu)

Convenience function for inserting a submenu menu item into this Menu. Combine g_menu_item_new_submenu() and g_menu_insert_item() for a more flexible alternative.

Parameters:

position - the position at which to insert the item

label - the section label, or null

submenu - a GMenuModel with the items of the submenu

prepend

public void prepend(@Nullable
 @Nullable String label,
 @Nullable
 @Nullable String detailedAction)

Convenience function for prepending a normal menu item to the start of this Menu. Combine g_menu_item_new() and g_menu_insert_item() for a more flexible alternative.

Parameters:

label - the section label, or null

detailedAction - the detailed action string, or null

prependItem

public void prependItem(MenuItem item)

Prepends item to the start of this Menu.

See g_menu_insert_item() for more information.

Parameters:

item - a GMenuItem to prepend

prependSection

public void prependSection(@Nullable
 @Nullable String label,
 MenuModel section)

Convenience function for prepending a section menu item to the start of this Menu. Combine g_menu_item_new_section() and g_menu_insert_item() for a more flexible alternative.

Parameters:

label - the section label, or null

section - a GMenuModel with the items of the section

prependSubmenu

public void prependSubmenu(@Nullable
 @Nullable String label,
 MenuModel submenu)

Convenience function for prepending a submenu menu item to the start of this Menu. Combine g_menu_item_new_submenu() and g_menu_insert_item() for a more flexible alternative.

Parameters:

label - the section label, or null

submenu - a GMenuModel with the items of the submenu

remove

public void remove(int position)

Removes an item from the menu.

position gives the index of the item to remove.

It is an error if position is not in range the range from 0 to one less than the number of items in the menu.

It is not possible to remove items by identity since items are added to the menu simply by copying their links and attributes (ie: identity of the item itself is not preserved).

Parameters:

position - the position of the item to remove

removeAll

public void removeAll()

Removes all items in the menu.

builder

public static Menu.Builder<? extends Menu.Builder> builder()

A Menu.Builder object constructs a Menu with the specified properties. Use the various set...() methods to set properties, and finish construction with Menu.Builder.build().
