Introduction to "Avalon"

"Avalon" is the code name for Microsoft's unified presentation subsystem for Windows. It consists of a display engine and a managed-code framework. "Avalon" unifies how Windows creates, displays, and manipulates documents, media, and user interfaces, which enables developers and designers to create visually stunning, differentiated user experiences that improve customer connection.

  • The "Avalon" Engine. The "Avalon" engine unifies the way developers and designers experience documents, media, and user interface (UI), providing a single runtime for browser-based experiences, forms-based applications, graphics, video, audio, and documents. "Avalon" is built on top of DirectX, which enables it to unleash the full power of the graphics hardware present in modern computers, and is engineered to exploit advances in hardware moving forward. For example, the "Avalon" vector-based rendering engine enables applications to scale to take advantage of high-dpi monitors without requiring extra work on the part of the developer or user. Similarly, when "Avalon" detects a video card that supports hardware acceleration, it takes advantage of it.
  • The "Avalon" Framework. The "Avalon" framework delivers solutions for media, user interface design, and documents that go well beyond what developers have today. "Avalon" is designed for extensibility, enabling developers to create their own controls on top of the "Avalon" engine from scratch or by subclassing existing "Avalon" controls. Central to the "Avalon" framework are controls for shapes, documents, images, video, animation, 3-D, and panels, in which to place controls and content. These primitives provide the building blocks for developing next generation user experiences.
  • XAML. "Avalon" also introduces XAML, a markup language to declaratively represent user interface for Windows applications, improving the richness of the tools with which developers and designers can compose and repurpose UI. For Web developers, XAML provides a familiar UI description paradigm. XAML also enables the separation of UI design from the underlying code, enabling developers and designers to work more closely together.

For developers and designers, "Avalon" provides a unified UI platform, such that they can learn a single paradigm that provides limitless possibilities of UI experiences. For .NET developers, its framework will be familiar, and it will ultimately reduce the number of lines of code required to deliver optimal user experiences. For designers, "Avalon" offers a platform that eliminates boundaries between content, media, and applications. Most importantly, "Avalon" has been engineered so that developers and designers can work closely together synchronously to quickly deliver differentiated, connected experiences.

Avalon March 2005 Community Technical Preview

The "Avalon" team is excited to release this next iteration. There are lots of new features in this release, a handful of which will be enumerated below. And, for those who worked with the November 2004 CTP, there are many changes. This article will touch on some of those changes, but it is not comprehensive.

Note on Community Technology Previews

Community Technical Preview (CTP) builds do not go through the same rigorous testing that beta builds undergo. While betas receive a much higher level of testing and feature work, CTPs are intended to expose developers to the latest working build. CTPs are therefore unsupported, prerelease software and there are some precautions you should take. Please read the latest Readme and Installation Guides before you download or install prerelease software.

Installing "Avalon"

"Avalon" requires the February CTP release of .NET Framework 2.0 to be installed.

In terms of hardware requirements, this CTP requires at least a 1-GHz Pentium-class processor with 256 MB of RAM. A DirectX 9-capable graphics card (for example, ATI Radeon 9600, nVidia GeForce 4, or better) is strongly recommended. The final hardware requirements for "Avalon" have not yet been announced.

WinFX SDK

The distribution for this release includes a release of the WinFX SDK, which includes documentation, tools, and samples for building "Avalon" managed applications. Because this is an interim pre-beta release, expect the documentation to be partially incomplete and some samples to be broken. Many of the new features in this CTP are not fully documented in the SDK. Expect future articles on MSDN to supplement the SDK.

This release also includes basic Visual Studio 2005 tools support for "Avalon" development, including updated templates for building applications running both inside and outside the browser, as well as "Avalon" controls. IntelliSense is provided for both code and markup, and build and debug support is enabled along with integrated help. Again, the release notes provide information on the required components and the correct install order to ensure everything is set up correctly.

Exploring the New Features

The list below is not comprehensive, but provides a glimpse of some of the advances and new features that are part of this release, with links to the SDK for more information.

Visual Brush

VisualBrush is a powerful tool that allows you to paint a visual tree of UI elements onto an "Avalon" element. It enables a high degree of reuse of existing "Avalon" visuals. It differs from the DrawingBrush in that it preserves layout. One of the most interesting use cases for the visual brush is the ability to grab existing content and filling in another part of the tree. A great example of this would be the type of functionality in PowerPoint where there is a small view of the slide to the left of the larger slide.

Below is a simple sample of how to use the visual brush, which paints a rectangle with a canvas that contains a grid of rectangles.

                <RowDefinition Height="*"/>
                <RowDefinition Height="10"/>
                <Rectangle Grid.Row="0" Fill="Red"/>
                <Rectangle Grid.Row="1" Fill="Green"/>
                <Rectangle Grid.Row="2" Fill="Red"/>
              </Grid>
            </Canvas>

      </Rectangle.Fill>
    </Rectangle>
</Page>

The visual brush can be used to paint 3-D surfaces with graphics created in the 2-D world. Below is a simple sample of a visual brush on a 3-D pyramid:

<Page xmlns="http://schemas.microsoft.com/winfx/avalon/2005"

Rotation3D

With the March CTP, doing rotation transforms on 3-D models becomes much easier. A new class called Rotation3D is introduced that allows rotations. Complementing the Rotation3D class are animation classes for doing rotation animations. One can still get the quaternion slerp behavior by doing a Rotation3DAnimation between two rotation 3-Ds, in which case the Axis/Angle pairs are treated like orientations à la Quaternions.

Building on the example above, below is a sample that rotates the 3-D object, hosted in a Window instead of a page:

<Window xmlns="http://schemas.microsoft.com/winfx/avalon/2005" 
   xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005" >
   
   < Window.Storyboards>

    <SetterTimeline TargetID="myViewport3D"
      Path="(Viewport3D.Models).(Model3DGroup.Children)[2].(GeometryModel3D.Transform).(RotateTransform3D.Rotation).Angle">
      <DoubleAnimation From="0" To="360" Duration="0:0:5" RepeatBehavior="Forever" />
    </SetterTimeline>
    </ParallelTimeline>
   </ Window.Storyboards>
<Grid Background="#333399">

    TextureCoordinates="0 1  1 1  0 0  1 0  0.5 0.5 "
    TriangleIndices="0 4 2 2 4 3 4 1 3 0 1 4" />

Event Triggers

Similar to property triggers, event triggers allow actions to occur when events are fired. They are especially useful when starting animations based on user input. The sample below gives a sense of how to use event triggers to start an animation based on the MouseEnter and MouseLeave events:

<Canvas 
    xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
    xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005">
  <Canvas.Resources>
    <Style x:Key="sample">
      <Button Width="100" Height="30"/>
      <Style.VisualTriggers>
        <EventTrigger RoutedEvent="Mouse.MouseEnter">
          <EventTrigger.Actions>
            <BeginAction TargetId="enterStoryboard"/>
          </EventTrigger.Actions>
        </EventTrigger>
        <EventTrigger RoutedEvent="Mouse.MouseLeave">
          <EventTrigger.Actions>
            <BeginAction TargetId="exitStoryboard"/>
          </EventTrigger.Actions>
        </EventTrigger>
      </Style.VisualTriggers>
      <Style.Storyboards>
        <SetterTimeline ID="enterStoryboard" BeginTime="*null" Path="(Button.Width)">
          <DoubleAnimation To="300" Duration="0:0:2"/>
        </SetterTimeline>
        <SetterTimeline ID="exitStoryboard" BeginTime="*null" Path="(Button.Width)">
          <DoubleAnimation To="100" Duration="0:0:2"/>
        </SetterTimeline>
      </Style.Storyboards>
    </Style>
  </Canvas.Resources>
  <Button Style="{sample}" Canvas.Left="50" Canvas.Top="10">Grow!</Button>
  <Button Style="{sample}" Canvas.Left="50" Canvas.Top="60">Grow!</Button>
  <Button Style="{sample}" Canvas.Left="50" Canvas.Top="110">Grow!</Button>
  <Button Style="{sample}" Canvas.Left="50" Canvas.Top="160">Grow!</Button>
</Canvas>

Aa480168.avalonmarch2005ctp03(en-us,MSDN.10).jpg

There are some things to be aware of with event triggers in this release. First, EventTriggers are only available within Styles, not on Elements, in this CTP. Also, note that animations from markup outside of Storyboards will likely be removed in the future. It is recommended that you use Storyboards for all animations moving forward. In writing EventTriggers within styles, you'll need to access elements in the Style's VisualTree. Lastly, the API currently lacks "BecameClicked" and "BecameUnclicked" events, so triggering alternative Storyboards depending on the Click state of a control is not currently possible. This should be resolved in a later release.

New Controls

Toolbar and ToolBarTray. The toolbar provides a container for a group of commands or controls. The ToolBarTray contains a set of toolbar items. Toolbars derives from the HeaderItemsControl, just as MenuItem is. Below is a sample of a toolbar tray with some toolbars:

<Page  
  xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
  xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005">
  <ToolBarTray>
    <ToolBar>
      <Canvas  Width= "100" Height="100"  >
        <Rectangle  Width="50" Height="25" 
               Canvas.Top="50" Canvas.Left="25" Fill="Red" />
        <Rectangle  Width="20" Height="15" 
               Canvas.Top="35" Canvas.Left="35" Fill="Red" />
        <Ellipse  RadiusX="6" RadiusY="6" CenterX="37" CenterY="75" 
               Fill="Black" />
        <Ellipse  RadiusX="6" RadiusY="6" CenterX="62" CenterY="75" 
               Fill="Black" />
        <Ellipse  RadiusX="5" RadiusY="5" CenterX="75" CenterY="65" 
             Fill="Yellow" />
      </Canvas>
    </ToolBar>
    <ToolBar>
      <TextBlock FontSize="20">Some Text</TextBlock></ToolBar>
  </ToolBarTray>
</Page>

Aa480168.avalonmarch2005ctp04(en-us,MSDN.10).jpg

Password Box. This control provides masking when typing in sensitive data. It includes properties such as PasswordChar for specifying the character that is displayed to the user and MaxLength for limiting the length. It has the additional feature of storing the password as a System.Security.SecureString, such that the text is encrypted for privacy when being used, and deleted from computer memory when no longer needed.

New Tool: XAMLPad

The WinFX SDK has a new tool that can be found in the SDK /bin directory called XAMLPad.exe. This tool allows you to edit XAML and see the results in real-time, as opposed to having to compile the XAML file to see the effect of a change.

The SDK Threading Model

The threading model has received a significant overhaul in this CTP. The model has switched from the rental threading model to a simpler "single" threading model. As such, the UIContext class is no longer available as a constructor for many of the classes. The Dispatcher class has replaced much of the functionality of the UIContext class.

Significant Changes

A number of things change with this release for those who have been working with the November 2004 Avalon CTP. While not comprehensive, the list below addresses some of the more significant changes.

XAML Changes

First, there have been changes to the XML namespace.

November CTP syntax

<Window x:Class=" "
    xmlns="http://schemas.microsoft.com/2003/xaml" xmlns:x="Definition"

March CTP syntax

< Window x:Class=" "
    xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
    xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"
    >

Second, when creating a style that can be referenced, use x:Key instead of x:Name.

November CTP syntax

<Style x:Name="myCanvasStyle">
         ...
</Style>

March CTP syntax

<Style x:Key="myCanvasStyle">
         ...
</Style>

Third, the syntax inside of attributes for non-literal values such as styles and classes have changed. The old syntax will still work in this CTP, but will be deprecated moving forward, so we recommend that you use the new syntax. See the SDK for more details.

November CTP syntaxMarch CTP syntax
"*null"
"{x:Null}"
"*typeof(Button)"
"{x:Type Button}"
"*Class.Field"
"{x:Static Class.Field}"
"*Bind(Path=firstname)"
"{Bind Path=firstname}"
"{foo}"
"{StaticResource foo}"
"{foo}"
"{DynamicResource foo}"
"{*typeof(Button)}"
"{Resource {x:Type Button}}"

Layout

There have been significant changes to how layout works in this release. Below is a list of some of the major things to watch for when working with the new layout model.

  • The FlowPanel has been replaced with the StackPanel.
  • Pane has been replaced with Page.
  • The GridPanel has been completely removed.
  • Many properties (Height, Width, Top, Bottom, etc.) are now of type Double as opposed to type Length. Also, percentages cannot be used to set relative properties any longer. Instead, to achieve the effect of 100%, set the HorizontalAlignment and VerticalAlignment properties to Stretch.
  • The Canvas element no longer does any implicit layout. The canvas is a surface in which every child element must declare its exact position and size.
  • Dock Filling has been changed, such that the "Fill" value of the enum has been removed and replaced with the LastChildFill Boolean property on DockPanel.

As you work with the layout engine, you will likely encounter many other modifications in both syntax and behavior.

Animation and Timing

The animation and timing system has received a significant overhaul to make them easier to understand and use and to avoid conflicting properties. The fundamental way timelines and animations work has changed. See the SDK for more information on how animation and timing now works. Moreover, there have been major syntactic changes to the API to make it clearer.

For example, time is now represented as TimeSpan-based values instead of Time values. When writing animations in XAML, time values for the new properties must be specified in markup using the TimeSpan format which is, at a glance, "0:0:3" == 3 seconds.

With regard to timelines, The ParallelTimeline class is the replacement for the current use of Timeline in markup and code. Timeline is now an abstract class. Creating a TimelineClock from a Timeline has been simplified to calling the CreateClock method.

For more information on animation and storyboards, see the Animation Overview and the Storyboards Overview.

Loose XAML

Support for "loose XAML" activation has been removed. You can no longer navigate to a .XAML file directly from the browser. However, you can still load XAML at runtime using the Parser.LoadXAML() method.

Changeable Becomes Freezable

The Changeable class has been modified and is now the Freezable class. Freezable works similarly to Changeable insofar as it provides a mechanism for simulating mutability with objects that are ostensibly immutable in cases when you need to modify an object after it has been used, for example changing a background color. The Changeable class had an important property called StatusOfNextUse, which took a UseStatus enumeration, which has been removed. See the WinFX SDK topic Freezable Objects Overview for more information.

What's Missing from This Release

Media (audio and video) and printing are both missing from this build. However, they will both be enabled in a future CTP release. Some demos that rely on these features will either not compile, or will in some cases simply silently fail on execution.
