GI.Gtk.Objects.WindowGroup

Contents

Description

A WindowGroup restricts the effect of grabs to windows in the same group, thereby making window groups almost behave like separate applications.

A window can be a member in at most one window group at a time. Windows that have not been explicitly assigned to a group are implicitly treated like windows of the default window group.

GtkWindowGroup objects are referenced by each window in the group, so once you have added all windows to a GtkWindowGroup, you can drop the initial reference to the window group with objectUnref. If the windows in the window group are subsequently destroyed, then they will be removed from the window group and drop their references on the window group; when all window have been removed, the window group will be freed.

Synopsis

Exported types

newtype WindowGroup Source #

Memory-managed wrapper type.

class GObject o => IsWindowGroup o Source #

Type class for types which can be safely cast to WindowGroup, for instance with toWindowGroup.

toWindowGroup :: (MonadIO m, IsWindowGroup o) => o -> m WindowGroup Source #

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

Methods

addWindow

windowGroupAddWindow Source #

Arguments

:: (HasCallStack, MonadIO m, IsWindowGroup a, IsWindow b) 
=> a

windowGroup: a WindowGroup

-> b

window: the Window to add

-> m () 

Adds a window to a WindowGroup.

getCurrentDeviceGrab

windowGroupGetCurrentDeviceGrab Source #

Arguments

:: (HasCallStack, MonadIO m, IsWindowGroup a, IsDevice b) 
=> a

windowGroup: a WindowGroup

-> b

device: a Device

-> m (Maybe Widget)

Returns: The grab widget, or Nothing

Returns the current grab widget for device, or Nothing if none.

Since: 3.0

getCurrentGrab

windowGroupGetCurrentGrab Source #

Arguments

:: (HasCallStack, MonadIO m, IsWindowGroup a) 
=> a

windowGroup: a WindowGroup

-> m Widget

Returns: the current grab widget of the group

Gets the current grab widget of the given group, see widgetGrabAdd.

Since: 2.22

listWindows

windowGroupListWindows Source #

Arguments

:: (HasCallStack, MonadIO m, IsWindowGroup a) 
=> a

windowGroup: a WindowGroup

-> m [Window]

Returns: A newly-allocated list of windows inside the group.

Returns a list of the GtkWindows that belong to windowGroup.

Since: 2.14

new

windowGroupNew Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> m WindowGroup

Returns: a new WindowGroup.

Creates a new WindowGroup object. Grabs added with widgetGrabAdd only affect windows within the same WindowGroup.

removeWindow

windowGroupRemoveWindow Source #

Arguments

:: (HasCallStack, MonadIO m, IsWindowGroup a, IsWindow b) 
=> a

windowGroup: a WindowGroup

-> b

window: the Window to remove

-> m () 

Removes a window from a WindowGroup.
