@Generated("io.github.jwharm.JavaGI")
public abstract class LayoutChild
extends GObject

The base class for objects that are meant to hold layout properties.

If a GtkLayoutManager has per-child properties, like their packing type, or the horizontal and vertical span, or the icon name, then the layout manager should use a GtkLayoutChild implementation to store those properties.

A GtkLayoutChild instance is only ever valid while a widget is part of a layout.

Constructor Details

LayoutChild

public LayoutChild(MemorySegment address)

Create a LayoutChild proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

LayoutChild

public LayoutChild()

Creates a new LayoutChild.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the LayoutChild class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected LayoutChild asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

getChildWidget

public Widget getChildWidget()

Retrieves the GtkWidget associated to the given layoutChild.

Returns:

a GtkWidget

getLayoutManager

public LayoutManager getLayoutManager()

Retrieves the GtkLayoutManager instance that created the given layoutChild.

Returns:

a GtkLayoutManager
