Struct gtk4::LinkButton
source · #[repr(transparent)]pub struct LinkButton { /* private fields */ }Expand description
A LinkButton is a button with a hyperlink.
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 FileLauncher::launch() 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§
source§impl LinkButton
impl LinkButton
sourcepub fn new(uri: &str) -> LinkButton
pub fn new(uri: &str) -> LinkButton
Creates a new LinkButton with the URI as its text.
uri
a valid URI
Returns
a new link button widget.
sourcepub fn with_label(uri: &str, label: &str) -> LinkButton
pub fn with_label(uri: &str, label: &str) -> LinkButton
Creates a new LinkButton containing a label.
uri
a valid URI
label
the text of the button
Returns
a new link button widget.
sourcepub fn builder() -> LinkButtonBuilder
pub fn builder() -> LinkButtonBuilder
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.
sourcepub fn uri(&self) -> GString
pub fn uri(&self) -> GString
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.
sourcepub fn is_visited(&self) -> bool
pub fn is_visited(&self) -> bool
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
sourcepub fn set_uri(&self, uri: &str)
pub fn set_uri(&self, uri: &str)
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
sourcepub fn set_visited(&self, visited: bool)
pub fn set_visited(&self, visited: bool)
Sets the “visited” state of the LinkButton.
See is_visited() for more details.
visited
the new “visited” state
sourcepub fn connect_activate_link<F: Fn(&Self) -> Inhibit + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_activate_link<F: Fn(&Self) -> Inhibit + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted each time the LinkButton is clicked.
The default handler will call FileLauncher::launch() 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
pub fn connect_uri_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
pub fn connect_visited_notify<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
