All Implemented Interfaces:

Proxy

@Generated("org.javagi.JavaGI")
public class DropControllerMotion
extends EventController

An event controller tracking the pointer during Drag-and-Drop operations.

It is modeled after EventControllerMotion so if you have used that, this should feel really familiar.

This controller is not able to accept drops, use DropTarget for that purpose.

Constructor Details

DropControllerMotion

public DropControllerMotion(MemorySegment address)

Create a DropControllerMotion instance for the provided memory address.

Parameters:

address - the memory address of the native object

DropControllerMotion

public DropControllerMotion()

Create a new DropControllerMotion.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the DropControllerMotion class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected DropControllerMotion asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class EventController

Returns:

the instance as if it were its parent type

containsPointer

public boolean containsPointer()

Returns if a Drag-and-Drop operation is within the widget this DropControllerMotion or one of its children.

Returns:

true if a dragging pointer is within this DropControllerMotion or one of its children.

getDrop

public @Nullable Drop getDrop()

Returns the GdkDrop of a current Drag-and-Drop operation over the widget of self.

Returns:

The GdkDrop currently happening within this DropControllerMotion

isPointer

public boolean isPointer()

Returns if a Drag-and-Drop operation is within the widget self, not one of its children.

Returns:

true if a dragging pointer is within this DropControllerMotion but not one of its children

onEnter

public SignalConnection<DropControllerMotion.EnterCallback> onEnter(DropControllerMotion.EnterCallback handler)

Signals that the pointer has entered the widget.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• DropControllerMotion.EnterCallback.run(double, double)

emitEnter

public void emitEnter(double x,
 double y)

Emits the "enter" signal. See onEnter(DropControllerMotion.EnterCallback).

onLeave

public SignalConnection<DropControllerMotion.LeaveCallback> onLeave(DropControllerMotion.LeaveCallback handler)

Signals that the pointer has left the widget.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• DropControllerMotion.LeaveCallback.run()

emitLeave

public void emitLeave()

Emits the "leave" signal. See onLeave(DropControllerMotion.LeaveCallback).

onMotion

public SignalConnection<DropControllerMotion.MotionCallback> onMotion(DropControllerMotion.MotionCallback handler)

Emitted when the pointer moves inside the widget.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• DropControllerMotion.MotionCallback.run(double, double)

emitMotion

public void emitMotion(double x,
 double y)

Emits the "motion" signal. See onMotion(DropControllerMotion.MotionCallback).

builder

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

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

Returns:

the builder object
