Struct gtk4::Stack

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 property::Settings::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.

Implementations

Creates a new Stack.

Returns

a new Stack

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.

Adds a child to @self.

child

the widget to add

Returns

the StackPage for @child

Adds a child to @self.

The child is identified by the @name.

child

the widget to add

name

the name for @child

Returns

the StackPage for @child

Adds a child to @self.

The child is identified by the @name. The @title will be used by StackSwitcher to represent @child in a tab bar, so it should be short.

child

the widget to add

name

the name for @child

title

a human-readable title for @child

Returns

the StackPage for @child

Finds the child with the name given as the argument.

Returns None if there is no child with this name.

name

the name of the child to find

Returns

the requested child of the Stack

Gets whether @self is horizontally homogeneous.

Returns

whether @self is horizontally homogeneous.

Returns whether the Stack is set up to interpolate between the sizes of children on page switch.

Returns

true if child sizes are interpolated

Returns the StackPage object for @child.

child

a child of @self

Returns

the StackPage for @child

Returns a GListModel that contains the pages of the stack.

This can be used to keep an up-to-date view. The model also implements SelectionModel and can be used to track and modify the visible page.

Returns

a SelectionModel for the stack’s children

Returns the amount of time (in milliseconds) that transitions between pages in @self will take.

Returns

the transition duration

Returns whether the @self is currently in a transition from one page to another.

Returns

true if the transition is currently running, false otherwise.

Gets the type of animation that will be used for transitions between pages in @self.

Returns

the current transition type of @self

Gets whether @self is vertically homogeneous.

Returns

whether @self is vertically homogeneous.

Gets the currently visible child of @self.

Returns None if there are no visible children.

Returns

the visible child of the Stack

Returns the name of the currently visible child of @self.

Returns None if there is no visible child.

Returns

the name of the visible child of the Stack

Removes a child widget from @self.

child

the child to remove

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

Sets whether or not @self will interpolate its size when changing the visible child.

If the property::Stack::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

Sets the duration that transitions between pages in @self will take.

duration

the new duration, in milliseconds

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

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

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

Makes the child with the given name visible.

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

transition

the transition type to use

Makes the child with the given name visible.

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.

name

the name of the child to make visible
