Exported types

newtype ClassGroup

Memory-managed wrapper type.

Constructors

Instances

GObject ClassGroup

Defined in GI.Wnck.Objects.ClassGroup

Methods

gobjectType :: ClassGroup -> IO GType

IsObject ClassGroup

Defined in GI.Wnck.Objects.ClassGroup

IsClassGroup ClassGroup

Defined in GI.Wnck.Objects.ClassGroup

class GObject o => IsClassGroup o

Type class for types which can be safely cast to ClassGroup, for instance with toClassGroup.

Instances

(GObject a, (UnknownAncestorError ClassGroup a :: Constraint)) => IsClassGroup a

Defined in GI.Wnck.Objects.ClassGroup

IsClassGroup ClassGroup

Defined in GI.Wnck.Objects.ClassGroup

toClassGroup :: (MonadIO m, IsClassGroup o) => o -> m ClassGroup

Cast to ClassGroup, for types for which this is known to be safe. For general casts, use castTo.

noClassGroup :: Maybe ClassGroup

A convenience alias for Nothing :: Maybe ClassGroup.

Methods

get

classGroupGet

Arguments

:: (HasCallStack, MonadIO m)

=> Text

id: identifier name of the sought resource class.

-> m ClassGroup

Returns: the ClassGroup corresponding to id, or Nothing if there is no ClassGroup with the specified id. The returned ClassGroup is owned by libwnck and must not be referenced or unreferenced.

Gets the ClassGroup corresponding to id.

Since: 2.2

getIcon

classGroupGetIcon

Arguments

:: (HasCallStack, MonadIO m, IsClassGroup a)

=> a

classGroup: a ClassGroup.

-> m Pixbuf

Returns: the icon for classGroup. The caller should reference the returned <classname>GdkPixbuf</classname> if it needs to keep the icon around.

Gets the icon to be used for classGroup. Since there is no way to properly find the icon, a suboptimal heuristic is used to find it. The icon is the first icon found by looking at all the Application for each Window in classGroup, then at all the Window in classGroup. If no icon was found, a fallback icon is used.

Since: 2.2

getId

classGroupGetId

Arguments

:: (HasCallStack, MonadIO m, IsClassGroup a)

=> a

classGroup: a ClassGroup.

-> m Text

Returns: the identifier name of classGroup, or an empty string if the group has no identifier name.

Gets the identifier name for classGroup. This is the resource class for classGroup.

Since: 3.2

getMiniIcon

classGroupGetMiniIcon

Arguments

:: (HasCallStack, MonadIO m, IsClassGroup a)

=> a

classGroup: a ClassGroup.

-> m Pixbuf

Returns: the mini-icon for classGroup. The caller should reference the returned <classname>GdkPixbuf</classname> if it needs to keep the mini-icon around.

Gets the mini-icon to be used for classGroup. Since there is no way to properly find the mini-icon, the same suboptimal heuristic as the one for classGroupGetIcon is used to find it.

Since: 2.2

getName

classGroupGetName

Arguments

:: (HasCallStack, MonadIO m, IsClassGroup a)

=> a

classGroup: a ClassGroup.

-> m Text

Returns: an human-readable name for classGroup.

Gets an human-readable name for classGroup. Since there is no way to properly find this name, a suboptimal heuristic is used to find it. The name is the name of all Application for each Window in classGroup if they all have the same name. If all Application don't have the same name, the name is the name of all Window in classGroup if they all have the same name. If all Window don't have the same name, the resource class name is used.

Since: 2.2

getResClass

classGroupGetResClass

Arguments

:: (HasCallStack, MonadIO m, IsClassGroup a)

=> a

classGroup: a ClassGroup.

-> m Text

Returns: the resource class name of classGroup, or an empty string if the group has no resource class name.

Deprecated: (Since version 3.2)Use classGroupGetId instead.

Gets the resource class name for classGroup.

Since: 2.2

getWindows

classGroupGetWindows

Arguments

:: (HasCallStack, MonadIO m, IsClassGroup a)

=> a

classGroup: a ClassGroup.

-> m [Window]

Returns: the list of Window grouped in classGroup, or Nothing if the group contains no window. The list should not be modified nor freed, as it is owned by classGroup.

Gets the list of Window that are grouped in classGroup.

Since: 2.2

Signals

iconChanged

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

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

type ClassGroupIconChangedCallback = IO ()

Emitted when the icon of classGroup changes.

afterClassGroupIconChanged :: (IsClassGroup a, MonadIO m) => a -> ClassGroupIconChangedCallback -> m SignalHandlerId

Connect a signal handler for the “icon-changed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after classGroup #iconChanged callback

genClosure_ClassGroupIconChanged :: ClassGroupIconChangedCallback -> IO Closure

Wrap the callback into a Closure.

mk_ClassGroupIconChangedCallback :: C_ClassGroupIconChangedCallback -> IO (FunPtr C_ClassGroupIconChangedCallback)

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

noClassGroupIconChangedCallback :: Maybe ClassGroupIconChangedCallback

A convenience synonym for Nothing :: Maybe ClassGroupIconChangedCallback.

onClassGroupIconChanged :: (IsClassGroup a, MonadIO m) => a -> ClassGroupIconChangedCallback -> m SignalHandlerId

Connect a signal handler for the “icon-changed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on classGroup #iconChanged callback

wrap_ClassGroupIconChangedCallback :: ClassGroupIconChangedCallback -> C_ClassGroupIconChangedCallback

Wrap a ClassGroupIconChangedCallback into a C_ClassGroupIconChangedCallback.

nameChanged

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

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

type ClassGroupNameChangedCallback = IO ()

Emitted when the name of classGroup changes.

afterClassGroupNameChanged :: (IsClassGroup a, MonadIO m) => a -> ClassGroupNameChangedCallback -> m SignalHandlerId

Connect a signal handler for the “name-changed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after classGroup #nameChanged callback

genClosure_ClassGroupNameChanged :: ClassGroupNameChangedCallback -> IO Closure

Wrap the callback into a Closure.

mk_ClassGroupNameChangedCallback :: C_ClassGroupNameChangedCallback -> IO (FunPtr C_ClassGroupNameChangedCallback)

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

noClassGroupNameChangedCallback :: Maybe ClassGroupNameChangedCallback

A convenience synonym for Nothing :: Maybe ClassGroupNameChangedCallback.

onClassGroupNameChanged :: (IsClassGroup a, MonadIO m) => a -> ClassGroupNameChangedCallback -> m SignalHandlerId

Connect a signal handler for the “name-changed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on classGroup #nameChanged callback

wrap_ClassGroupNameChangedCallback :: ClassGroupNameChangedCallback -> C_ClassGroupNameChangedCallback

Wrap a ClassGroupNameChangedCallback into a C_ClassGroupNameChangedCallback.
