Description

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 “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.

Functions

webkit_color_chooser_request_get_rgba ()

void
webkit_color_chooser_request_get_rgba (WebKitColorChooserRequest *request,
                                       GdkRGBA *rgba);

Gets the current GdkRGBA color of request

Parameters

request	a WebKitColorChooserRequest
rgba	a GdkRGBA to fill in with the current color.	[out]

Since: 2.8

webkit_color_chooser_request_set_rgba ()

void
webkit_color_chooser_request_set_rgba (WebKitColorChooserRequest *request,
                                       const GdkRGBA *rgba);

Sets the current GdkRGBA color of request

Parameters

request	a WebKitFileChooserRequest
rgba	a pointer GdkRGBA

Since: 2.8

webkit_color_chooser_request_get_element_rectangle ()

void
webkit_color_chooser_request_get_element_rectangle
                               (WebKitColorChooserRequest *request,
                                GdkRectangle *rect);

Gets the bounding box of the color input element.

Parameters

request	a WebKitColorChooserRequest
rect	a GdkRectangle to fill in with the element area.	[out]

Since: 2.8

webkit_color_chooser_request_finish ()

void
webkit_color_chooser_request_finish (WebKitColorChooserRequest *request);

Finishes request and the input element keeps the current value of “rgba”. The signal “finished” is emitted to notify that the request has finished.

Parameters

request

a WebKitColorChooserRequest

Since: 2.8

webkit_color_chooser_request_cancel ()

void
webkit_color_chooser_request_cancel (WebKitColorChooserRequest *request);

Cancels request and the input element changes to use the initial color it has before the request started. The signal “finished” is emitted to notify that the request has finished.

Parameters

request

a WebKitColorChooserRequest

Since: 2.8

Types and Values

struct WebKitColorChooserRequest

struct WebKitColorChooserRequest;

Property Details

The `“rgba”` property

  “rgba”                     GdkRGBA *

The current RGBA color for the request.

Owner: WebKitColorChooserRequest

Flags: Read / Write / Construct

Signal Details

The `“finished”` signal

void
user_function (WebKitColorChooserRequest *request,
               gpointer                   user_data)

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

request	the WebKitColorChooserRequest on which the signal is emitted
user_data	user data set when the signal handler was connected.

Flags: Run Last
