#[repr(transparent)]pub struct Stack { /* private fields */ }
Expand description
Stack
is a container which only shows one of its children
at a time.
In contrast to Notebook
, Stack
does not provide a means
for users to change the visible child. Instead, a separate widget
such as StackSwitcher
or StackSidebar
can
be used with Stack
to provide this functionality.
Transitions between pages can be animated as slides or fades. This
can be controlled with set_transition_type()
.
These animations respect the gtk-enable-animations
setting.
Stack
maintains a StackPage
object for each added
child, which holds additional per-child properties. You
obtain the StackPage
for a child with page()
and you can obtain a SelectionModel
containing all the pages
with pages()
.
GtkStack as GtkBuildable
To set child-specific properties in a .ui file, create StackPage
objects explicitly, and set the child widget as a property on it:
<object class="GtkStack" id="stack">
<child>
<object class="GtkStackPage">
<property name="name">page1</property>
<property name="title">In the beginning…</property>
<property name="child">
<object class="GtkLabel">
<property name="label">It was dark</property>
</object>
</property>
</object>
</child>
CSS nodes
Stack
has a single CSS node named stack.
Accessibility
Stack
uses the AccessibleRole::TabPanel
for the stack
pages, which are the accessible parent objects of the child widgets.

Creates a new builder-pattern struct instance to construct Stack
objects.
This method returns an instance of StackBuilder
which can be used to create Stack
objects.

and modify the visible page.
Returns
a SelectionModel
for the stack’s children
sourcepub fn transition_duration(&self) -> u32
pub fn transition_duration(&self) -> u32
Returns the amount of time (in milliseconds) that transitions between pages in @self will take.
Returns
the transition duration
sourcepub fn is_transition_running(&self) -> bool
pub fn is_transition_running(&self) -> bool
sourcepub fn transition_type(&self) -> StackTransitionType

sourcepub fn set_hhomogeneous(&self, hhomogeneous: bool)
pub fn set_hhomogeneous(&self, hhomogeneous: bool)
Sets the Stack
to be horizontally homogeneous or not.
If it is homogeneous, the Stack
will request the same
width for all its children. If it isn’t, the stack
may change width when a different child becomes visible.
hhomogeneous
true
to make @self horizontally homogeneous
sourcepub fn set_interpolate_size(&self, interpolate_size: bool)
pub fn set_interpolate_size(&self, interpolate_size: bool)
Sets whether or not @self will interpolate its size when changing the visible child.
If the interpolate-size
property is set
to true
, @self will interpolate its size between the current
one and the one it’ll take after changing the visible child,
according to the set transition duration.
interpolate_size
the new value
sourcepub fn set_transition_duration(&self, duration: u32)
pub fn set_transition_duration(&self, duration: u32)
Sets the duration that transitions between pages in @self will take.
duration
the new duration, in milliseconds
sourcepub fn set_transition_type(&self, transition: StackTransitionType)
pub fn set_transition_type(&self, transition: StackTransitionType)
Sets the type of animation that will be used for transitions between pages in @self.
Available types include various kinds of fades and slides.
The transition type can be changed without problems at runtime, so it is possible to change the animation based on the page that is about to become current.
transition
the new transition type
sourcepub fn set_vhomogeneous(&self, vhomogeneous: bool)
pub fn set_vhomogeneous(&self, vhomogeneous: bool)
Sets the Stack
to be vertically homogeneous or not.
If it is homogeneous, the Stack
will request the same
height for all its children. If it isn’t, the stack
may change height when a different child becomes visible.
vhomogeneous
true
to make @self vertically homogeneous
sourcepub fn set_visible_child(&self, child: &impl IsA<Widget>)
pub fn set_visible_child(&self, child: &impl IsA<Widget>)
Makes @child the visible child of @self.
If @child is different from the currently visible child, the transition between the two will be animated with the current transition type of @self.
Note that the @child widget has to be visible itself
(see WidgetExt::show()
) in order to become the visible
child of @self.
child
a child of @self
sourcepub fn set_visible_child_full(
&self,
name: &str,
transition: StackTransitionType
)

Note that the child widget has to be visible itself
(see WidgetExt::show()
) in order to become the visible
child of @self.
name
the name of the child to make visible
