public class DragIcon
extends Widget
implements Accessible, Buildable, ConstraintTarget, Native, Root

GtkDragIcon is a GtkRoot implementation for drag icons.

A drag icon moves with the pointer during a Drag-and-Drop operation and is destroyed when the drag ends.

To set up a drag icon and associate it with an ongoing drag operation, use getForDrag(org.gnome.gdk.Drag) to get the icon for a drag. You can then use it like any other widget and use setChild(org.gnome.gtk.Widget) to set whatever widget should be used for the drag icon.

Keep in mind that drag icons do not allow user input.

Constructor Details

DragIcon

public DragIcon(MemorySegment address)

Create a DragIcon proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the DragIcon class

Returns:

the GType

asParent

protected DragIcon 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 Widget

getForDrag

public static DragIcon getForDrag(Drag drag)

Gets the GtkDragIcon in use with drag.

If no drag icon exists yet, a new one will be created and shown.

Parameters:

drag - a GdkDrag

Returns:

the GtkDragIcon

createWidgetForValue

public static Widget createWidgetForValue(Value value)

Creates a widget that can be used as a drag icon for the given value.

Supported types include strings, GdkRGBA and GtkTextBuffer. If GTK does not know how to create a widget for a given value, it will return null.

This method is used to set the default drag icon on drag-and-drop operations started by GtkDragSource, so you don't need to set a drag icon using this function there.

Parameters:

value - a GValue

Returns:

A new GtkWidget for displaying value as a drag icon.

setFromPaintable

public static void setFromPaintable(Drag drag,
 Paintable paintable,
 int hotX,
 int hotY)

Creates a GtkDragIcon that shows paintable, and associates it with the drag operation.

The hotspot position on the paintable is aligned with the hotspot of the cursor.

Parameters:

drag - a GdkDrag

paintable - a GdkPaintable to display

hotX - X coordinate of the hotspot

hotY - Y coordinate of the hotspot

getChild

public Widget getChild()

Gets the widget currently used as drag icon.

Returns:

The drag icon

setChild

public void setChild(@Nullable
 @Nullable Widget child)

Sets the widget to display as the drag icon.

Parameters:

child - a GtkWidget

builder

public static DragIcon.Builder<? extends DragIcon.Builder> builder()

A DragIcon.Builder object constructs a DragIcon with the specified properties. Use the various set...() methods to set properties, and finish construction with DragIcon.Builder.build().
