Struct gtk4::Revealer [−][src]
pub struct Revealer(_);
Expand description
A Revealer
animates the transition of its child from invisible to visible.
The style of transition can be controlled with
set_transition_type()
.
These animations respect the property::Settings::gtk-enable-animations
setting.
CSS nodes
Revealer
has a single CSS node with name revealer.
When styling Revealer
using CSS, remember that it only hides its contents,
not itself. That means applied margin, padding and borders will be visible even
when the property::Revealer::reveal-child
property is set to false
.
Accessibility
Revealer
uses the AccessibleRole::Group
role.
The child of Revealer
, if set, is always available in the accessibility
tree, regardless of the state of the revealer widget.

Implementations
Creates a new builder-pattern struct instance to construct Revealer
objects.
This method returns an instance of RevealerBuilder
which can be used to create Revealer
objects.
Returns whether the child is currently revealed.
This function returns true
as soon as the transition
is to the revealed state is started. To learn whether
the child is fully revealed (ie the transition is completed),
use is_child_revealed()
.
Returns
true
if the child is revealed.
Returns the amount of time (in milliseconds) that transitions will take.
Returns
the transition duration
Gets the type of animation that will be used
for transitions in self
.
Returns
the current transition type of self
Tells the Revealer
to reveal or conceal its child.
The transition will be animated with the current
transition type of self
.
reveal_child
true
to reveal the child
Sets the type of animation that will be used for
transitions in self
.
Available types include various kinds of fades and slides.
transition
the new transition type
