Struct gtk4::LinkButton

source ·
#[repr(transparent)]
pub struct LinkButton { /* private fields */ }
Expand description

A LinkButton is a button with a hyperlink.

An example GtkLinkButton

It is useful to show quick links to resources.

A link button is created by calling either new() or with_label(). If using the former, the URI you pass to the constructor is used as a label for the widget.

The URI bound to a LinkButton can be set specifically using set_uri().

By default, LinkButton calls show_uri() when the button is clicked. This behaviour can be overridden by connecting to the signal::LinkButton::activate-link signal and returning true from the signal handler.

CSS nodes

LinkButton has a single CSS node with name button. To differentiate it from a plain Button, it gets the .link style class.

Accessibility

LinkButton uses the AccessibleRole::Link role.

Implementations§

Creates a new LinkButton with the URI as its text.

uri

a valid URI

Returns

a new link button widget.

Creates a new LinkButton containing a label.

uri

a valid URI

label

the text of the button

Returns

a new link button widget.

Creates a new builder-pattern struct instance to construct LinkButton objects.

This method returns an instance of LinkButtonBuilder which can be used to create LinkButton objects.

Retrieves the URI of the LinkButton.

Returns

a valid URI. The returned string is owned by the link button and should not be modified or freed.

Retrieves the “visited” state of the LinkButton.

The button becomes visited when it is clicked. If the URI is changed on the button, the “visited” state is unset again.

The state may also be changed using set_visited().

Returns

true if the link has been visited, false otherwise

Sets @uri as the URI where the LinkButton points.

As a side-effect this unsets the “visited” state of the button.

uri

a valid URI

Sets the “visited” state of the LinkButton.

See is_visited() for more details.

visited

the new “visited” state

Emitted each time the LinkButton is clicked.

The default handler will call show_uri() with the URI stored inside the property::LinkButton::uri property.

To override the default behavior, you can connect to the ::activate-link signal and stop the propagation of the signal by returning true from your handler.

Returns

true if the signal has been handled
