GI.Gtk.Objects.ToolItem

GtkToolItems are widgets that can appear on a toolbar. To create a toolbar item that contain something else than a button, use toolItemNew. Use containerAdd to add a child widget to the tool item.

For toolbar items that contain buttons, see the ToolButton, ToggleToolButton and RadioToolButton classes.

See the Toolbar class for a description of the toolbar widget, and ToolShell for a description of the tool shell interface.

Properties

isImportant

No description available in the introspection data.

constructToolItemIsImportant :: IsToolItem o => Bool -> IO (GValueConstruct o)

getToolItemIsImportant :: (MonadIO m, IsToolItem o) => o -> m Bool

Get the value of the “is-important” property. When overloading is enabled, this is equivalent to

get toolItem #isImportant

setToolItemIsImportant :: (MonadIO m, IsToolItem o) => o -> Bool -> m ()

Set the value of the “is-important” property. When overloading is enabled, this is equivalent to

set toolItem [ #isImportant := value ]

visibleHorizontal

No description available in the introspection data.

constructToolItemVisibleHorizontal :: IsToolItem o => Bool -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “visible-horizontal” property. This is rarely needed directly, but it is used by new.

getToolItemVisibleHorizontal :: (MonadIO m, IsToolItem o) => o -> m Bool

Get the value of the “visible-horizontal” property. When overloading is enabled, this is equivalent to

get toolItem #visibleHorizontal

setToolItemVisibleHorizontal :: (MonadIO m, IsToolItem o) => o -> Bool -> m ()

Set the value of the “visible-horizontal” property. When overloading is enabled, this is equivalent to

set toolItem [ #visibleHorizontal := value ]

visibleVertical

No description available in the introspection data.

constructToolItemVisibleVertical :: IsToolItem o => Bool -> IO (GValueConstruct o)

Signals

createMenuProxy

type C_ToolItemCreateMenuProxyCallback = Ptr () -> Ptr () -> IO CInt

Type for the callback on the (unwrapped) C side.

type ToolItemCreateMenuProxyCallback

Arguments

 = IO Bool

Returns: True if the signal was handled, False if not

This signal is emitted when the toolbar needs information from toolItem about whether the item should appear in the toolbar overflow menu. In response the tool item should either

• call toolItemSetProxyMenuItem with a Nothing pointer and return True to indicate that the item should not appear in the overflow menu
• call toolItemSetProxyMenuItem with a new menu item and return True, or
• return False to indicate that the signal was not handled by the item. This means that the item will not appear in the overflow menu unless a later handler installs a menu item.

The toolbar may cache the result of this signal. When the tool item changes how it will respond to this signal it must call toolItemRebuildMenu to invalidate the cache and ensure that the toolbar rebuilds its overflow menu.

afterToolItemCreateMenuProxy :: (IsToolItem a, MonadIO m) => a -> ToolItemCreateMenuProxyCallback -> m SignalHandlerId

Connect a signal handler for the createMenuProxy signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after toolItem #createMenuProxy callback

genClosure_ToolItemCreateMenuProxy :: MonadIO m => ToolItemCreateMenuProxyCallback -> m (GClosure C_ToolItemCreateMenuProxyCallback)

Wrap the callback into a GClosure.

mk_ToolItemCreateMenuProxyCallback :: C_ToolItemCreateMenuProxyCallback -> IO (FunPtr C_ToolItemCreateMenuProxyCallback)

Generate a function pointer callable from C code, from a C_ToolItemCreateMenuProxyCallback.

noToolItemCreateMenuProxyCallback :: Maybe ToolItemCreateMenuProxyCallback

A convenience synonym for Nothing :: Maybe ToolItemCreateMenuProxyCallback.

onToolItemCreateMenuProxy :: (IsToolItem a, MonadIO m) => a -> ToolItemCreateMenuProxyCallback -> m SignalHandlerId

Connect a signal handler for the createMenuProxy signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on toolItem #createMenuProxy callback

wrap_ToolItemCreateMenuProxyCallback :: ToolItemCreateMenuProxyCallback -> C_ToolItemCreateMenuProxyCallback

Wrap a ToolItemCreateMenuProxyCallback into a C_ToolItemCreateMenuProxyCallback.

toolbarReconfigured

type C_ToolItemToolbarReconfiguredCallback = Ptr () -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type ToolItemToolbarReconfiguredCallback = IO ()

This signal is emitted when some property of the toolbar that the item is a child of changes. For custom subclasses of ToolItem, the default handler of this signal use the functions

• toolShellGetOrientation
• toolShellGetStyle
• toolShellGetIconSize
• toolShellGetReliefStyle

to find out what the toolbar should look like and change themselves accordingly.

afterToolItemToolbarReconfigured :: (IsToolItem a, MonadIO m) => a -> ToolItemToolbarReconfiguredCallback -> m SignalHandlerId

Connect a signal handler for the toolbarReconfigured signal, to be run after the default handler. When overloading is enabled, this is equivalent to

genClosure_ToolItemToolbarReconfigured :: MonadIO m => ToolItemToolbarReconfiguredCallback -> m (GClosure C_ToolItemToolbarReconfiguredCallback)

Wrap the callback into a GClosure.

mk_ToolItemToolbarReconfiguredCallback :: C_ToolItemToolbarReconfiguredCallback -> IO (FunPtr C_ToolItemToolbarReconfiguredCallback)
