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 setTarget(TargetNewWindow). 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.

When linking to a resource, the anchor does not assume ownership of resource, so that you may share the same resources for several anchors.

Usage example:

// Create an anchor that links to a URL
a = new WAnchor("http://www.webtoolkit.eu/", "Wt web toolkit", this);
// Create an anchor that links to an internal path
a = new WAnchor(WLink(WLink::InternalPath, "/docs/" + myDocName()), "Doc", this);
// 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 = new PdfResource(this); // serializes to a PDF file.
a = new WAnchor(r, "PDF version", this);
a->setTarget(TargetNewWindow);

WAnchor is an inline widget.

Note
If you set a text or image using one of the API methods like setText() or setImage() or a constructor, you should not attempt to remove all contents (using clear(), or provide a layout (using setLayout()), as this will result in undefined behaviour: the text or image are simply inserted as widgets into the container.

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

Wt::WAnchor::WAnchor ( const WLink link,
WContainerWidget parent = 0 
)

Creates an anchor for the given link.

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

See also
setLink()
Wt::WAnchor::WAnchor ( const WLink link,
const WString text,
WContainerWidget parent = 0 
)

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()
Wt::WAnchor::WAnchor ( const WLink link,
WImage image,
WContainerWidget parent = 0 
)

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

bool Wt::WAnchor::canReceiveFocus ( ) const
virtual

Returns whether the widget can receive focus.

See also
setCanReceiveFocus()

Reimplemented from Wt::WWebWidget.

void Wt::WAnchor::enableAjax ( )
protectedvirtual

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.

WImage* Wt::WAnchor::image ( ) const

Returns the image.

Returns 0 if no image is set.

See also
setImage()
const WLink& Wt::WAnchor::link ( ) const

Returns the link.

See also
setLink()
void Wt::WAnchor::propagateSetEnabled ( bool  enabled)
protectedvirtual

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.

std::string& Wt::WAnchor::ref ( ) const

Returns the destination URL or internal path (deprecated).

When the anchor links to a resource, the current resource URL is returned. When the anchor links to an internal path, the internal path is returned. Otherwise, the linked URL is returned.

Deprecated:
Use link() instead.
WResource * Wt::WAnchor::resource ( ) const

Returns the destination resource (deprecated).

Returns 0 if no resource has been set.

Deprecated:
Use link() instead.
bool Wt::WAnchor::setFirstFocus ( )
virtual

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.

void Wt::WAnchor::setImage ( WImage image)

Sets an image.

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

Ownership of the image is transferred to the anchor.

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.

void Wt::WAnchor::setRef ( const std::string &  url)

Sets the linked URL (deprecated).

Deprecated:
Use setLink() instead.
void Wt::WAnchor::setRefInternalPath ( const std::string &  path)

Sets a link to an internal path (deprecated).

Note
the path should be UTF8 encoded (we may fix the API to use WString in the future).
Deprecated:
Use setLink() instead.
void Wt::WAnchor::setResource ( WResource resource)

Sets a destination resource (deprecated).

The anchor does not assume ownership of the resource.

Deprecated:
Use setLink() instead.
void Wt::WAnchor::setTarget ( AnchorTarget  target)

Sets the location where the linked content should be displayed.

By default, the linked content is displayed in the application (Wt::TargetSelf). When the destination is an HTML document, the application is replaced with the new document. When the link is to a document that cannot be displayed in the browser, it is offered for download or opened using an external program, depending on browser settings.

By setting target to Wt::TargetNewWindow, the destination is displayed in a new browser window or tab.

See also
target()
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().

void Wt::WAnchor::setTextFormat ( TextFormat  format)

Configures the text format.

The default text format is XHTMLText.

See also
WText::setTextFormat()
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()
int Wt::WAnchor::tabIndex ( ) const
virtual

Returns the tab index.

See also
setTabIndex()

Reimplemented from Wt::WWebWidget.

AnchorTarget Wt::WAnchor::target ( ) const

Returns the location where the linked content should be displayed.

See also
setTarget()
const WString & Wt::WAnchor::text ( ) const

Returns the label text.

Returns an empty string if no label was set.

See also
setText()
TextFormat Wt::WAnchor::textFormat ( ) const

Returns the text format.

See also
setTextFormat()
bool Wt::WAnchor::wordWrap ( ) const

Returns whether the widget may break lines.

See also
setWordWrap(bool)
