Description

A menu widget

Synopsis

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.

Types

data Menu Source

Instances

class MenuShellClass o => MenuClass o Source

Instances

castToMenu :: GObjectClass obj => obj -> Menu Source

gTypeMenu :: GType Source

toMenu :: MenuClass o => o -> Menu Source

Constructors

menuNew :: IO Menu Source

Creates a new Menu.

Methods

menuReorderChild Source

Arguments

:: (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 Source

Arguments

:: MenuClass self 
=> self

The menu to be shown.

-> Maybe (MouseButton, TimeStamp)

The mouse button returned by eventButton and the time of the event returned by eventTime. These values are used to match the corresponding release 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 Source

Arguments

:: 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 Source

Arguments

:: 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 Source

Arguments

:: (MenuClass self, GlibString string) 
=> 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, GlibString string) => self -> string -> IO () Source

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

menuGetTitle Source

Arguments

:: (MenuClass self, GlibString string) 
=> 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 () Source

Removes the menu from the screen.

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

Repositions the menu according to its position function.

menuGetActive Source

Arguments

:: 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 Source

Arguments

:: 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 Source

Arguments

:: 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 Source

Arguments

:: 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 () Source

Attach this menu to another widget.

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

Detach this menu from the widget it is attached to.

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

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

menuSetScreen Source

Arguments

:: 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 Source

Arguments

:: 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 Source

Arguments

:: (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 Source

Arguments

:: 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
