All Implemented Interfaces:

Accessible, Actionable, Buildable, ConstraintTarget, Proxy

@Generated("io.github.jwharm.JavaGI")
public class Switch
extends Widget
implements Accessible, Actionable, Buildable, ConstraintTarget

Shows a "light switch" that has two states: on or off.

The user can control which state should be active by clicking the empty area, or by dragging the slider.

GtkSwitch can also express situations where the underlying state changes with a delay. In this case, the slider position indicates the user's recent change (represented by the Gtk.Switch:active property), while the trough color indicates the present underlying state (represented by the Gtk.Switch:state property).

See Gtk.Switch::state-set for details.

Shortcuts and Gestures
GtkSwitch supports pan and drag gestures to move the slider.

CSS nodes

 switch
 ├── image
 ├── image
 ╰── slider
 

GtkSwitch has four css nodes, the main node with the name switch and subnodes for the slider and the on and off images. Neither of them is using any style classes.

Accessibility
GtkSwitch uses the Gtk.AccessibleRole.switch role.

Constructor Details

Switch

public Switch(MemorySegment address)

Create a Switch proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Switch

public Switch()

Creates a new Switch.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the Switch class

Returns:

the GType

asParent

protected Switch 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

getActive

public boolean getActive()

Gets whether the GtkSwitch is in its “on” or “off” state.

Returns:

true if the GtkSwitch is active, and false otherwise

getState

public boolean getState()

Gets the underlying state of the GtkSwitch.

Returns:

the underlying state

setActive

public void setActive(boolean isActive)

Changes the state of this Switch to the desired one.

Parameters:

isActive - true if this Switch should be active, and false otherwise

setState

public void setState(boolean state)

Sets the underlying state of the GtkSwitch.

This function is typically called from a Gtk.Switch::state-set signal handler in order to set up delayed state changes.

See Gtk.Switch::state-set for details.

Parameters:

state - the new state

onActivate

public SignalConnection<Switch.ActivateCallback> onActivate(Switch.ActivateCallback handler)

Emitted to animate the switch.

Applications should never connect to this signal, but use the Gtk.Switch:active property.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• Switch.ActivateCallback.run()

emitActivate

public void emitActivate()

Emits the "activate" signal. See onActivate(org.gnome.gtk.Switch.ActivateCallback).

onStateSet

public SignalConnection<Switch.StateSetCallback> onStateSet(Switch.StateSetCallback handler)

Emitted to change the underlying state.

The ::state-set signal is emitted when the user changes the switch position. The default handler calls setState(boolean) with the value of state.

To implement delayed state change, applications can connect to this signal, initiate the change of the underlying state, and call setState(boolean) when the underlying state change is complete. The signal handler should return true to prevent the default handler from running.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• Switch.StateSetCallback.run(boolean)

emitStateSet

public boolean emitStateSet(boolean state)

Emits the "state-set" signal. See onStateSet(org.gnome.gtk.Switch.StateSetCallback).

builder

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

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

Returns:

the builder object
