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.
void webkit_color_chooser_request_get_rgba (WebKitColorChooserRequest *request,GdkRGBA *rgba);
Gets the current GdkRGBA color of request
Since 2.8
void webkit_color_chooser_request_set_rgba (WebKitColorChooserRequest *request,const GdkRGBA *rgba);
Sets the current GdkRGBA color of request
Since 2.8
void webkit_color_chooser_request_get_element_rectangle (WebKitColorChooserRequest *request,GdkRectangle *rect);
Gets the bounding box of the color input element.
Since 2.8
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.
Since 2.8
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.
Since 2.8
“rgba” property“rgba” GdkRGBA *
The current RGBA color for the request.
Flags: Read / Write / Construct
“finished” signalvoid 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.
