Detailed Description

A widget that represents an HTML anchor (to link to other documents).

Use an anchor to link to another web page, document, internal application path or a resource (which specifies application-dependent content that may be generated by your application on demand). The anchor may contain a label text, an image, or any other widget (as it inherits from WContainerWidget).

If you link to a document or external url, and do not want the application to terminate when the user follows the anchor, you must use link.setTarget(LinkTarget::NewWindow). Even for non-HTML documents, this may be important since pending Ajax requests are cancelled if documents are not served within the browser window in certain browsers.

Usage example:

WAnchor *a;
 
// Create an anchor that links to a URL
a = addWidget(std::make_unique<Wt::WAnchor>("https://www.webtoolkit.eu/", "Wt web toolkit"));
 
// Create an anchor that links to an internal path
a = addWidget(std::make_unique<Wt::WAnchor>(
      WLink(LinkType::InternalPath, "/docs/" + myDocName()), "Doc"));
//   and listen to the corresponding change in internal path
WApplication::instance()->internalPathChanged().connect(this, &DocsListWidget::onInternalPathChange);
 
// Create an anchor that links to a resource
WResource *r = addChild(std::make_unique<PdfResource>()); // serializes to a PDF file.
a = addWidget(std::make_unique<Wt::WAnchor>(r, "PDF version"));

WAnchor is an inline widget.

CSS

The widget corresponds to the HTML <a> tag and does not provide styling. It can be styled using inline or external CSS as appropriate.

Constructor & Destructor Documentation

WAnchor() [1/3]

Wt::WAnchor::WAnchor

(

const WLink &

link

)

Creates an anchor for the given link.

The link may point to a URL, a dynamic resource, or an internal path.

See also

setLink()

WAnchor() [2/3]

Wt::WAnchor::WAnchor	(	const WLink &	link,
		const WString &	text
	)

Creates an anchor for the given link with a text.

The link may point to a URL, a dynamic resource, or an internal path.

See also

setLink(), setText()

WAnchor() [3/3]

Wt::WAnchor::WAnchor	(	const WLink &	link,
		std::unique_ptr< WImage >	image
	)

Creates an anchor for the given link with an image.

Ownership of the image is transferred to the anchor.

See also

setLink(), setImage()

Member Function Documentation

canReceiveFocus()

bool Wt::WAnchor::canReceiveFocus ( ) const

overridevirtual

Returns whether the widget can receive focus.

See also

setCanReceiveFocus()

Reimplemented from Wt::WWebWidget.

enableAjax()

void Wt::WAnchor::enableAjax ( )

overrideprotectedvirtual

Progresses to an Ajax-enabled widget.

This method is called when the progressive bootstrap method is used, and support for AJAX has been detected. The default behavior will upgrade the widget's event handling to use AJAX instead of full page reloads, and propagate the call to its children.

You may want to reimplement this method if you want to make changes to widget when AJAX is enabled. You should always call the base implementation.

See also

WApplication::enableAjax()

Reimplemented from Wt::WWebWidget.

image()

WImage* Wt::WAnchor::image

(

)

const

Returns the image.

Returns 0 if no image is set.

See also

setImage()

link()

const WLink& Wt::WAnchor::link

(

)

const

Returns the link.

See also

setLink()

propagateSetEnabled()

void Wt::WAnchor::propagateSetEnabled ( bool  enabled )

overrideprotectedvirtual

Propagates that a widget was enabled or disabled through children.

When enabling or disabling a widget, you usually also want to disable contained children. This method is called by setDisabled() to propagate its state to all children.

You may want to reimplement this method if they wish to render differently when a widget is disabled. The default implementation will propagate the signal to all children.

Reimplemented from Wt::WInteractWidget.

setFirstFocus()

bool Wt::WAnchor::setFirstFocus ( )

overridevirtual

Set focus on the widget's first descendant.

Set focus on the widget itself, or on a first descendant which can receive focus.

Returns whether focus could be set.

Reimplemented from Wt::WWebWidget.

setImage()

void Wt::WAnchor::setImage

(

std::unique_ptr< WImage >

image

)

Sets an image.

If an image was previously set, it is deleted. The image is added using addWidget().

setLink()

void Wt::WAnchor::setLink

(

const WLink &

link

)

Sets the link.

The link may hold a URL, a resource, or an internal path.

When the link points to a resource, the contents of the link may be generated by your application on demand.

When the link points to an internal path, activating the anchor will change the application's internal path or open a new session with the given path as initial path). This is the easiest way to let the application participate in browser history, and generate URLs that are bookmarkable and search engine friendly.

setText()

void Wt::WAnchor::setText

(

const WString &

text

)

Sets the label text.

If no text was previously set, a new WText widget is added using addWidget().

setTextFormat()

void Wt::WAnchor::setTextFormat

(

TextFormat

format

)

Configures the text format.

The default text format is TextFormat::XHTML.

See also

WText::setTextFormat()

setWordWrap()

void Wt::WAnchor::setWordWrap

(

bool

wordWrap

)

Configures text word wrapping.

When wordWrap is true, the text set with setText() may be broken up over multiple lines. When wordWrap is false, the text will displayed on a single line, unless the text contains <br /> tags or other block-level tags.

The default value is true.

See also

wordWrap()

tabIndex()

int Wt::WAnchor::tabIndex ( ) const

overridevirtual

Returns the tab index.

See also

setTabIndex()

Reimplemented from Wt::WWebWidget.

text()

const WString & Wt::WAnchor::text

(

)

const

Returns the label text.

Returns an empty string if no label was set.

See also

setText()

textFormat()

TextFormat Wt::WAnchor::textFormat

(

)

const

Returns the text format.

See also

setTextFormat()

wordWrap()

bool Wt::WAnchor::wordWrap

(

)

const

Returns whether the widget may break lines.
