GI.Gtk.Objects.WindowGroup
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.

Setters
addWindow
Arguments
| :: (HasCallStack, MonadIO m, IsWindowGroup a, IsWindow b) | |
| => a |
|
| -> b |
|
| -> m () |
Adds a window to a WindowGroup.
getCurrentDeviceGrab
windowGroupGetCurrentDeviceGrab Source #
Arguments
| :: (HasCallStack, MonadIO m, IsWindowGroup a, IsDevice b) | |
| => a |
|
| -> b |
|
| -> m (Maybe Widget) | Returns: The grab widget, or |
Returns the current grab widget for device, or Nothing if none.
Since: 3.0
getCurrentGrab
windowGroupGetCurrentGrab Source #
Arguments
| :: (HasCallStack, MonadIO m, IsWindowGroup a) | |
| => a |
|
| -> m Widget | Returns: the current grab widget of the group |
Gets the current grab widget of the given group,
see widgetGrabAdd.
Since: 2.22

windowGroupListWindows Source #
Arguments
| :: (HasCallStack, MonadIO m, IsWindowGroup a) | |
| => a |
|
| -> m [Window] | Returns: A newly-allocated list of windows inside the group. |

new
Arguments

| => a |
|
