Detail

A Menu is a MenuShell that implements a drop down menu consisting of a list of MenuItem objects which can be navigated and activated by the user to perform application functions.

A Menu is most commonly dropped down by activating a MenuItem in a MenuBar or popped up by activating a MenuItem in another Menu.

A Menu can also be popped up by activating a OptionMenu. Other composite widgets such as the Notebook can pop up a Menu as well.

Applications can display a Menu as a popup menu by calling the menuPopup function.

Constructors

menuNew :: IO Menu

Creates a new Menu.

Methods

menuReorderChild

:: (MenuClass self, MenuItemClass child)
=> self
-> child	`child` - the `MenuItem` to move.
-> Int	`position` - the new position to place `child`. Positions are numbered from 0 to n-1.
-> IO ()
Moves a `MenuItem` to a new position within the `Menu`.

menuPopup

:: MenuClass self
=> self	The menu to be shown.
-> Maybe (MouseButton, TimeStamp)	The mouse button from the `Button` event and the time of the event. These values are used to match the corresponding relase of the button. If this context menu is shown by programmatic means, supply `Nothing`.
-> IO ()
Popup a context menu where a button press occurred. This function must be called in response to a button click. It opens the given menu at a place determined by the last emitted event (hence the requirement that this function is called as response to a button press signal).

menuSetAccelGroup

:: MenuClass self
=> self
-> AccelGroup	`accelGroup` - the `AccelGroup` to be associated with the menu.
-> IO ()
Set the `AccelGroup` which holds global accelerators for the menu. This accelerator group needs to also be added to all windows that this menu is being used in with windowAddAccelGroup, in order for those windows to support all the accelerators contained in this group.

menuGetAccelGroup

:: MenuClass self
=> self
-> IO AccelGroup	returns the `AccelGroup` associated with the menu.
Gets the `AccelGroup` which holds global accelerators for the menu. See `menuSetAccelGroup`.

menuSetAccelPath

:: MenuClass self
=> self
-> String	`accelPath` - a valid accelerator path
-> IO ()
Sets an accelerator path for this menu from which accelerator paths for its immediate children, its menu items, can be constructed. The main purpose of this function is to spare the programmer the inconvenience of having to call menuItemSetAccelPath on each menu item that should support runtime user changable accelerators. Instead, by just calling `menuSetAccelPath` on their parent, each menu item of this menu, that contains a label describing its purpose, automatically gets an accel path assigned. For example, a menu containing menu items "New" and "Exit", will, after calling menu `menuSetAccelPath` "<Gnumeric-Sheet>/File" assign its items the accel paths: `"<Gnumeric-Sheet>/File/New"` and `"<Gnumeric-Sheet>/File/Exit"`. Assigning accel paths to menu items then enables the user to change their accelerators at runtime. More details about accelerator paths and their default setups can be found at accelMapAddEntry.

menuSetTitle :: MenuClass self => self -> String -> IO ()

Sets the title string for the menu. The title is displayed when the menu is shown as a tearoff menu.

menuGetTitle

:: MenuClass self
=> self
-> IO (Maybe String)	returns the title of the menu, or `Nothing` if the menu has no title set on it.
Returns the title of the menu. See `menuSetTitle`.

menuPopdown :: MenuClass self => self -> IO ()

Removes the menu from the screen.

menuReposition :: MenuClass self => self -> IO ()

Repositions the menu according to its position function.

menuGetActive

:: MenuClass self
=> self
-> IO MenuItem	returns the `MenuItem` that was last selected in the menu. If a selection has not yet been made, the first menu item is selected.
Returns the selected menu item from the menu. This is used by the `OptionMenu`.

menuSetActive

:: MenuClass self
=> self
-> Int	`index` - the index of the menu item to select. Index values are from 0 to n-1.
-> IO ()
Selects the specified menu item within the menu. This is used by the `OptionMenu` and should not be used by anyone else.

menuSetTearoffState

:: MenuClass self
=> self
-> Bool	`tornOff` - If `True`, menu is displayed as a tearoff menu.
-> IO ()
Changes the tearoff state of the menu. A menu is normally displayed as drop down menu which persists as long as the menu is active. It can also be displayed as a tearoff menu which persists until it is closed or reattached.

menuGetTearoffState

:: MenuClass self
=> self
-> IO Bool	returns `True` if the menu is currently torn off.
Returns whether the menu is torn off. See `menuSetTearoffState`.

menuAttachToWidget :: (MenuClass self, WidgetClass attachWidget) => self -> attachWidget -> IO ()

Attach this menu to another widget.

menuDetach :: MenuClass self => self -> IO ()

Detach this menu from the widget it is attached to.

menuGetAttachWidget :: MenuClass self => self -> IO (Maybe Widget)

Get the widget this menu is attached to. Returns Nothing if this is a tearoff (context) menu.

menuSetScreen

:: MenuClass self
=> self
-> Maybe Screen	`screen` - a `Screen`, or `Nothing` if the screen should be determined by the widget the menu is attached to.
-> IO ()
Sets the `Screen` on which the menu will be displayed. Available since Gtk+ version 2.2

menuSetMonitor

:: MenuClass self
=> self
-> Int	`monitorNum` - the number of the monitor on which the menu should be popped up
-> IO ()
Informs Gtk+ on which monitor a menu should be popped up. See screenGetMonitorGeometry. Available since Gtk+ version 2.4

menuAttach

:: (MenuClass self, MenuItemClass child)
=> self
-> child	`child` - a `MenuItem`.
-> Int	`leftAttach` - The column number to attach the left side of the item to.
-> Int	`rightAttach` - The column number to attach the right side of the item to.
-> Int	`topAttach` - The row number to attach the top of the item to.
-> Int	`bottomAttach` - The row number to attach the bottom of the item to.
-> IO ()
Adds a new `MenuItem` to a (table) menu. The number of 'cells' that an item will occupy is specified by `leftAttach`, `rightAttach`, `topAttach` and `bottomAttach`. These each represent the leftmost, rightmost, uppermost and lower column and row numbers of the table. (Columns and rows are indexed from zero). Note that this function is not related to `menuDetach`. Available since Gtk+ version 2.4

menuGetForAttachWidget

:: WidgetClass widget
=> widget	`widget` - a `Widget`
-> IO [Menu]
Returns a list of the menus which are attached to this widget. Available since Gtk+ version 2.6
