All Implemented Interfaces:

Proxy

@Generated("org.javagi.JavaGI")
public class GestureLongPress
extends GestureSingle

Recognizes long press gestures.

This gesture is also known as “Press and Hold”.

When the timeout is exceeded, the gesture is triggering the Gtk.GestureLongPress::pressed signal.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the Gtk.GestureLongPress::cancelled signal will be emitted.

How long the timeout is before the ::pressed signal gets emitted is determined by the Gtk.Settings:gtk-long-press-time setting. It can be modified by the Gtk.GestureLongPress:delay-factor property.

Constructor Details

GestureLongPress

public GestureLongPress(MemorySegment address)

Create a GestureLongPress instance for the provided memory address.

Parameters:

address - the memory address of the native object

GestureLongPress

public GestureLongPress()

Create a new GestureLongPress.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the GestureLongPress class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected GestureLongPress 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 GestureSingle

Returns:

the instance as if it were its parent type

getDelayFactor

public double getDelayFactor()

Returns the delay factor.

Returns:

the delay factor

setDelayFactor

public void setDelayFactor(double delayFactor)

Applies the given delay factor.

The default long press time will be multiplied by this value. Valid values are in the range [0.5..2.0].

Parameters:

delayFactor - The delay factor to apply

onCancelled

public SignalConnection<GestureLongPress.CancelledCallback> onCancelled(GestureLongPress.CancelledCallback handler)

Emitted whenever a press moved too far, or was released before Gtk.GestureLongPress::pressed happened.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• GestureLongPress.CancelledCallback.run()

emitCancelled

public void emitCancelled()

Emits the "cancelled" signal. See onCancelled(GestureLongPress.CancelledCallback).

onPressed

public SignalConnection<GestureLongPress.PressedCallback> onPressed(GestureLongPress.PressedCallback handler)

Emitted whenever a press goes unmoved/unreleased longer than what the GTK defaults tell.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• GestureLongPress.PressedCallback.run(double, double)

emitPressed

public void emitPressed(double x,
 double y)

Emits the "pressed" signal. See onPressed(GestureLongPress.PressedCallback).

builder

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

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

Returns:

the builder object
