PointerInterface

public class Root
extends Interface

An interface for widgets that can act as the root of a widget hierarchy.

The root widget takes care of providing the connection to the windowing
system and manages layout, drawing and event delivery for its widget
hierarchy.

The obvious example of a `GtkRoot` is `GtkWindow`.

To get the display to which a `GtkRoot` belongs, use
[method@Gtk.Root.get_display].

`GtkRoot` also maintains the location of keyboard focus inside its widget
hierarchy, with [method@Gtk.Root.set_focus] and [method@Gtk.Root.get_focus].

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

getDisplay

public Display getDisplay()

Returns the display that this `GtkRoot` is on.

Gibt zurück:

the display of @root

getFocus

public Widget getFocus()

Retrieves the current focused widget within the root.

Note that this is the widget that would have the focus
if the root is active; if the root is not focused then
`gtk_widget_has_focus (widget)` will be %FALSE for the
widget.

Gibt zurück:

the currently focused widget

setFocus

public void setFocus(@Nullable
 Widget focus)

If @focus is not the current focus widget, and is focusable, sets
it as the focus widget for the root.

If @focus is %NULL, unsets the focus widget for the root.

To set the focus to a particular widget in the root, it is usually
more convenient to use [method@Gtk.Widget.grab_focus] instead of
this function.

Parameter:

focus - widget to be the new focus widget, or %NULL to unset the focus widget

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
