GI.Gtk.Objects.Stack

GtkStack is a container which only shows one of its children at a time.

In contrast to GtkNotebook, GtkStack 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 GtkStack to provide this functionality.

Transitions between pages can be animated as slides or fades. This can be controlled with stackSetTransitionType. These animations respect the Settings:gtkEnableAnimations setting.

GtkStack maintains a StackPage object for each added child, which holds additional per-child properties. You obtain the GtkStackPage for a child with stackGetPage and you can obtain a GtkSelectionModel containing all the pages with stackGetPages.

GtkStack as GtkBuildable

To set child-specific properties in a .ui file, create GtkStackPage objects explicitly, and set the child widget as a property on it:

xml code

 <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

GtkStack has a single CSS node named stack.

Accessibility

GtkStack uses the AccessibleRoleTabPanel for the stack pages, which are the accessible parent objects of the child widgets.

=> a

stack: a GtkStack

-> Word32

-> StackTransitionType

transition: the new transition type

-> m ()

Sets the type of animation that will be used for transitions between pages in stack.

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.

setVhomogeneous

stackSetVhomogeneous

Arguments

:: (HasCallStack, MonadIO m, IsStack a)

=> a

stack: a GtkStack

-> Bool

vhomogeneous: True to make stack vertically homogeneous

Arguments

:: (HasCallStack, MonadIO m, IsStack a, IsWidget b)

=> a

stack: a GtkStack

-> b

child: a child of stack

-> m ()

Makes child the visible child of stack.

If child is different from the currently visible child, the transition between the two will be animated with the current transition type of stack.

Note that the child widget has to be visible itself (see widgetShow) in order to become the visible child of stack.

setVisibleChildFull

stackSetVisibleChildFull

Arguments

:: (HasCallStack, MonadIO m, IsStack a)

=> a

stack: a GtkStack

-> Text

name: the name of the child to make visible

-> StackTransitionType

transition: the transition type to use

Arguments

:: (HasCallStack, MonadIO m, IsStack a)

=> a

stack: a GtkStack

-> Text

name: the name of the child to make visible

-> m ()

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 stack.

Note that the child widget has to be visible itself (see widgetShow) in order to become the visible child of stack.
