Description

An action which can be triggered by a menu or toolbar item

Module available since Gtk+ version 2.4

Synopsis

Detail

Actions represent operations that the user can be perform, along with some information how it should be presented in the interface. Each action provides methods to create icons, menu items and toolbar items representing itself.

As well as the callback that is called when the action gets activated, the following also gets associated with the action:

a name (not translated, for path lookup)
a label (translated, for display)
an accelerator
whether label indicates a stock id
a tooltip (optional, translated)
a toolbar label (optional, shorter than label)

The action will also have some state information:

visible (shown/hidden)
sensitive (enabled/disabled)

Apart from regular actions, there are toggle actions, which can be toggled between two states and radio actions, of which only one in a group can be in the "active" state. Other actions can be implemented as Action subclasses.

Each action can have one or more proxy menu item, toolbar button or other proxy widgets. Proxies mirror the state of the action (text label, tooltip, icon, visible, sensitive, etc), and should change when the action's state changes. When the proxy is activated, it should activate its action.

Constructors

actionNew Source

Arguments

:: GlibString string
=> string	`name` - A unique name for the action
-> string	`label` - the label displayed in menu items and on buttons
-> Maybe string	`tooltip` - a tooltip for the action
-> Maybe StockId	`stockId` - the stock icon to display in widgets representing the action
-> IO Action

Creates a new Action object. To add the action to a ActionGroup and set the accelerator for the action, call actionGroupAddActionWithAccel. See Graphics.UI.Gtk.ActionMenuToolbar.UIManager for information on allowed action names.

Methods

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

Returns the name of the action.

actionIsSensitive Source

Arguments

:: ActionClass self
=> self
-> IO Bool	returns `True` if the action and its associated action group are both sensitive.

Returns whether the action is effectively sensitive.

actionGetSensitive Source

Arguments

:: ActionClass self
=> self
-> IO Bool	returns `True` if the action itself is sensitive.

Returns whether the action itself is sensitive. Note that this doesn't necessarily mean effective sensitivity. See actionIsSensitive for that.

actionSetSensitive Source

Arguments

:: ActionClass self
=> self
-> Bool	`sensitive` - `True` to make the action sensitive
-> IO ()

Sets the sensitive property of the action to sensitive. Note that this doesn't necessarily mean effective sensitivity. See actionIsSensitive for that.

Available since Gtk+ version 2.6

actionIsVisible Source

Arguments

:: ActionClass self
=> self
-> IO Bool	returns `True` if the action and its associated action group are both visible.

Returns whether the action is effectively visible.

actionGetVisible Source

Arguments

:: ActionClass self
=> self
-> IO Bool	returns `True` if the action itself is visible.

Returns whether the action itself is visible. Note that this doesn't necessarily mean effective visibility. See actionIsSensitive for that.

actionSetVisible Source

Arguments

:: ActionClass self
=> self
-> Bool	`visible` - `True` to make the action visible
-> IO ()

Sets the visible property of the action to visible. Note that this doesn't necessarily mean effective visibility. See actionIsVisible for that.

Available since Gtk+ version 2.6

actionActivate :: ActionClass self => self -> IO () Source

Emits the "activate" signal on the specified action, if it isn't insensitive. This gets called by the proxy widgets when they get activated.

It can also be used to manually activate an action.

actionCreateMenuItem Source

Arguments

:: ActionClass self
=> self
-> IO Widget	returns a menu item connected to the action.

Creates a menu item widget that proxies for the given action.

actionCreateToolItem Source

Arguments

:: ActionClass self
=> self
-> IO Widget	returns a toolbar item connected to the action.

Creates a toolbar item widget that proxies for the given action.

actionConnectProxy Source

Arguments

:: (ActionClass self, WidgetClass proxy)
=> self
-> proxy	`proxy` - the proxy widget
-> IO ()

Connects a widget to an action object as a proxy. Synchronises various properties of the action with the widget (such as label text, icon, tooltip, etc), and attaches a callback so that the action gets activated when the proxy widget does.

If the widget is already connected to an action, it is disconnected first.

Removed in Gtk3.

actionDisconnectProxy Source

Arguments

:: (ActionClass self, WidgetClass proxy)
=> self
-> proxy	`proxy` - the proxy widget
-> IO ()

Disconnects a proxy widget from an action.

Removed in Gtk3.

actionGetProxies :: ActionClass self => self -> IO [Widget] Source

Returns the proxy widgets for an action.

actionConnectAccelerator :: ActionClass self => self -> IO () Source

Installs the accelerator for action if action has an accel path and group. See actionSetAccelPath and actionSetAccelGroup

Since multiple proxies may independently trigger the installation of the accelerator, the action counts the number of times this function has been called and doesn't remove the accelerator until actionDisconnectAccelerator has been called as many times.

actionDisconnectAccelerator :: ActionClass self => self -> IO () Source

Undoes the effect of one call to actionConnectAccelerator.

actionGetAccelPath Source

Arguments

:: (ActionClass self, GlibString string)
=> self
-> IO (Maybe string)	returns the accel path for this action, or `Nothing` if none is set.

Returns the accel path for this action.

Available since Gtk+ version 2.6

actionSetAccelPath Source

Arguments

:: (ActionClass self, GlibString string)
=> self
-> string	`accelPath` - the accelerator path
-> IO ()

Sets the accel path for this action. All proxy widgets associated with the action will have this accel path, so that their accelerators are consistent.

actionSetAccelGroup :: ActionClass self => self -> AccelGroup -> IO () Source

Sets the AccelGroup in which the accelerator for this action will be installed.

Attributes
