implements Accessible, Buildable, ConstraintTarget

A view container for ViewSwitcher.

AdwViewStack is a container which only shows one page at a time. It is typically used to hold an application's main views.

It doesn't provide a way to transition between pages. Instead, a separate widget such as ViewSwitcher can be used with AdwViewStack to provide this functionality.

AdwViewStack pages can have a title, an icon, an attention request, and a numbered badge that ViewSwitcher will use to let users identify which page is which. Set them using the ViewStackPage:title, ViewStackPage:icon-name, ViewStackPage:needs-attention, and ViewStackPage:badge-number properties.

Unlike Stack, transitions between views can only be animated via a crossfade and size changes are always interpolated. Animations are disabled by default. Use ViewStack:enable-transitions to enable them.

AdwViewStack maintains a ViewStackPage object for each added child, which holds additional per-child properties. You obtain the ViewStackPage for a child with getPage(org.gnome.gtk.Widget) and you can obtain a SelectionModel containing all the pages with getPages().

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

  <object class="AdwViewStack" id="stack">
     <child>
       <object class="AdwViewStackPage">
         <property name="name">overview</property>
         <property name="title">Overview</property>
         <property name="child">
           <object class="AdwStatusPage">
             <property name="title">Welcome!</property>
           </object>
         </property>
       </object>
     </child>
   </object>
 

CSS nodes
AdwViewStack has a single CSS node named stack.

Accessibility
AdwViewStack uses the GTK_ACCESSIBLE_ROLE_TAB_PANEL for the stack pages which are the accessible parent objects of the child widgets.

Constructor Details

ViewStack

public ViewStack(MemorySegment address)

Create a ViewStack proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ViewStack

public ViewStack()

Creates a new ViewStack.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ViewStack class

Returns:

the GType

asParent

protected ViewStack asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Widget

add

public ViewStackPage add(Widget child)

Adds a child to self.

Parameters:

child - the widget to add

Returns:

the ViewStackPage for child

addNamed

public ViewStackPage addNamed(Widget child,
 @Nullable String name)

Adds a child to self.

The child is identified by the name.

Parameters:

child - the widget to add

name - the name for child

Returns:

the AdwViewStackPage for child

addTitled

public ViewStackPage addTitled(Widget child,
 @Nullable String name,
 String title)

Adds a child to self.

The child is identified by the name. The title will be used by ViewSwitcher to represent child, so it should be short.

Parameters:

child - the widget to add

name - the name for child

title - a human-readable title for child

Returns:

the AdwViewStackPage for child

addTitledWithIcon

public ViewStackPage addTitledWithIcon(Widget child,
 @Nullable String name,
 String title,
 String iconName)

Adds a child to self.

The child is identified by the name. The title and iconName will be used by ViewSwitcher to represent child.

Parameters:

child - the widget to add

name - the name for child

title - a human-readable title for child

iconName - an icon name for child

Returns:

the AdwViewStackPage for child

Since:

1.2

getChildByName

public @Nullable Widget getChildByName(String name)

Finds the child with name in self.

Parameters:

name - the name of the child to find

Returns:

the requested child

getEnableTransitions

public boolean getEnableTransitions()

Gets whether this ViewStack uses a crossfade transition between pages.

Use ViewStack:transition-duration to control the duration, and ViewStack:transition-running to know when the transition is running.

Returns:

whether to enable page transitions

Since:

1.7

getHhomogeneous

public boolean getHhomogeneous()

Gets whether this ViewStack is horizontally homogeneous.

Returns:

whether this ViewStack is horizontally homogeneous

getPage

public ViewStackPage getPage(Widget child)

Gets the ViewStackPage object for child.

Parameters:

child - a child of this ViewStack

Returns:

the page object for child

getPages

public SelectionModel getPages()

Returns a ListModel 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 change the visible page.

Returns:

a GtkSelectionModel for the stack's children

getTransitionDuration

public int getTransitionDuration()

Gets the transition animation duration for self.

Returns:

the transition duration, in milliseconds

Since:

1.7

getTransitionRunning

public boolean getTransitionRunning()

Gets whether a transition is currently running for self.

If a transition is impossible, the property value will be set to TRUE and then immediately to FALSE, so it's possible to rely on its notifications to know that a transition has happened.

Returns:

whether a transition is currently running

Since:

1.7

getVhomogeneous

public boolean getVhomogeneous()

Gets whether this ViewStack is vertically homogeneous.

Returns:

whether this ViewStack is vertically homogeneous

getVisibleChild

public @Nullable Widget getVisibleChild()

Gets the currently visible child of self.

Returns:

the visible child

getVisibleChildName

public @Nullable String getVisibleChildName()

Returns the name of the currently visible child of self.

Returns:

the name of the visible child

remove

public void remove(Widget child)

Removes a child widget from self.

Parameters:

child - the child to remove

setEnableTransitions

public void setEnableTransitions(boolean enableTransitions)

Sets whether this ViewStack uses a crossfade transition between pages.

Parameters:

enableTransitions - whether to enable page transitions

Since:

1.7

setHhomogeneous

public void setHhomogeneous(boolean hhomogeneous)

Sets this ViewStack to be horizontally homogeneous or not.

If the stack is horizontally homogeneous, it allocates the same width for all children.

If it's FALSE, the stack may change width when a different child becomes visible.

Parameters:

hhomogeneous - whether to make this ViewStack horizontally homogeneous

setTransitionDuration

public void setTransitionDuration(int duration)

Sets the transition animation duration for self.

Only used when ViewStack:enable-transitions is set to TRUE.

Parameters:

duration - the new duration, in milliseconds

Since:

1.7

setVhomogeneous

public void setVhomogeneous(boolean vhomogeneous)

Sets this ViewStack to be vertically homogeneous or not.

If the stack is vertically homogeneous, it allocates the same height for all children.

If it's FALSE, the stack may change height when a different child becomes visible.

Parameters:

vhomogeneous - whether to make this ViewStack vertically homogeneous

setVisibleChild

public void setVisibleChild(Widget child)

Makes child the visible child of self.

Parameters:

child - a child of this ViewStack

setVisibleChildName

public void setVisibleChildName(String name)

Makes the child with name visible.

See ViewStack:visible-child.

Parameters:

name - the name of the child

builder

public static ViewStack.Builder<? extends ViewStack.Builder> builder()

A ViewStack.Builder object constructs a ViewStack with the specified properties. Use the various set...() methods to set properties, and finish construction with ViewStack.Builder.build().

Returns:

the builder object
