@Generated("io.github.jwharm.JavaGI")
public final class ColorChooserRequest
extends GObject

A request to open a color chooser.

Whenever the user interacts with an <input type='color' /> HTML element, WebKit will need to show a dialog to choose a color. For that to happen in a general way, instead of just opening a GtkColorChooser (which might be not desirable in some cases, which could prefer to use their own color chooser dialog), WebKit will fire the WebKitWebView::run-color-chooser signal with a WebKitColorChooserRequest object, which will allow the client application to specify the color to be selected, to inspect the details of the request (e.g. to get initial color) and to cancel the request, in case nothing was selected.

In case the client application does not wish to handle this signal, WebKit will provide a default handler which will asynchronously run a regular GtkColorChooserDialog for the user to interact with.

Constructor Details

ColorChooserRequest

public ColorChooserRequest(MemorySegment address)

Create a ColorChooserRequest 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 ColorChooserRequest class

Returns:

the GType

asParent

protected ColorChooserRequest 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

cancel

public void cancel()

Cancels this ColorChooserRequest and the input element changes to use the initial color.

Cancels this ColorChooserRequest and the input element changes to use the initial color it has before the request started. The signal WebKitColorChooserRequest::finished is emitted to notify that the request has finished.

finish

public void finish()

Finishes this ColorChooserRequest and the input element keeps the current value of WebKitColorChooserRequest:rgba.

Finishes this ColorChooserRequest and the input element keeps the current value of WebKitColorChooserRequest:rgba. The signal WebKitColorChooserRequest::finished is emitted to notify that the request has finished.

getElementRectangle

public void getElementRectangle(Rectangle rect)

Gets the bounding box of the color input element.

Parameters:

rect - a GdkRectangle to fill in with the element area

getRgba

public void getRgba(RGBA rgba)

Gets the current GdkRGBA color of this ColorChooserRequest

Parameters:

rgba - a GdkRGBA to fill in with the current color.

setRgba

public void setRgba(RGBA rgba)

Sets the current GdkRGBA color of this ColorChooserRequest

Parameters:

rgba - a pointer GdkRGBA

onFinished

public SignalConnection<ColorChooserRequest.FinishedCallback> onFinished(ColorChooserRequest.FinishedCallback handler)

Emitted when the request finishes. This signal can be emitted because the user completed the request calling webkit_color_chooser_request_finish(), or cancelled it with webkit_color_chooser_request_cancel() or because the color input element is removed from the DOM.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

• ColorChooserRequest.FinishedCallback.run()

emitFinished

public void emitFinished()

Emits the "finished" signal. See onFinished(org.gnome.webkit.ColorChooserRequest.FinishedCallback).

builder

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

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