GI.Gio.Objects.Menu

Menu is a simple implementation of MenuModel. You populate a Menu 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 menuInsert. To add a section, use menuInsertSection. To add a submenu, use menuInsertSubmenu.

Methods

Overloaded methods

append

menuAppend

Arguments

:: (HasCallStack, MonadIO m, IsMenu a)

=> a

menu: a Menu

-> Maybe Text

label: the section label, or Nothing

-> Maybe Text

detailedAction: the detailed action string, or Nothing

-> m ()

Convenience function for appending a normal menu item to the end of menu. Combine menuItemNew and menuInsertItem for a more flexible alternative.

Since: 2.32

appendItem

menuAppendItem

Arguments

:: (HasCallStack, MonadIO m, IsMenu a, IsMenuItem b)

=> a

menu: a Menu

-> b

item: a MenuItem to append

-> m ()

Appends item to the end of menu.

See menuInsertItem for more information.

Since: 2.32

appendSection

menuAppendSection

Arguments

:: (HasCallStack, MonadIO m, IsMenu a, IsMenuModel b)

=> a

menu: a Menu

-> Maybe Text

label: the section label, or Nothing

-> b

section: a MenuModel with the items of the section

-> m ()

Convenience function for appending a section menu item to the end of menu. Combine menuItemNewSection and menuInsertItem for a more flexible alternative.

Since: 2.32

appendSubmenu

menuAppendSubmenu

Arguments

:: (HasCallStack, MonadIO m, IsMenu a, IsMenuModel b)

=> a

menu: a Menu

-> Maybe Text

label: the section label, or Nothing

-> b

submenu: a MenuModel with the items of the submenu

-> m ()

Convenience function for appending a submenu menu item to the end of menu. Combine menuItemNewSubmenu and menuInsertItem for a more flexible alternative.

Since: 2.32

freeze

menuFreeze

Arguments

:: (HasCallStack, MonadIO m, IsMenu a)

=> a

menu: a Menu

-> m ()

Marks 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 Menu API must no longer be used.

This function causes menuModelIsMutable to begin returning False, which has some positive performance implications.

Since: 2.32

insert

menuInsert

Arguments

:: (HasCallStack, MonadIO m, IsMenu a)

=> a

menu: a Menu

-> Int32

position: the position at which to insert the item

-> Maybe Text

label: the section label, or Nothing

-> Maybe Text

detailedAction: the detailed action string, or Nothing

-> m ()

Convenience function for inserting a normal menu item into menu. Combine menuItemNew and menuInsertItem for a more flexible alternative.

Since: 2.32

insertItem

menuInsertItem

Arguments

:: (HasCallStack, MonadIO m, IsMenu a, IsMenuItem b)

=> a

menu: a Menu

-> Int32

position: the position at which to insert the item

-> b

item: the MenuItem to insert

-> m ()

Inserts item into 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 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 menuInsert, menuInsertSection and menuInsertSubmenu as well as "prepend" and "append" variants of each of these functions.

-> b

section: a MenuModel with the items of the section

menu: a Menu

-> Int32

position: the position of the item to remove

-> m ()

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).

removeAll

menuRemoveAll

Arguments

:: (HasCallStack, MonadIO m, IsMenu a)

=> a
