It will provide a sound foundation for distributed application development. Emphasis of the course is on enterprise level development of applications. Continuation of the study of design patterns, frameworks, and architectures.

Survey of current middleware architectures. Design of distributed systems using middleware. Measurement theory and appropriate use of metrics in design. Designing for qualities such as performance, safety, security, reusability, reliability, scalability.

Measuring internal qualities and complexity of software. Most WPF classes derive from dispatcherobject and are therefore inherently thread-unsafe. Dependencyobject is the base class for any object that can support dependency properties, one of the main topics in this chapter.

Freezables, once frozen, can be safely shared among multiple threads, unlike all other dispatcherobjects. Frozen objects can never be unfrozen, but you can clone them to create unfrozen copies. Most Freezables are graphics primitives such as brushes, pens, and geometries or animation classes.

Visual is the base class for all objects that have their own 2D visual representation. Uielement is the base class for all 2D visual objects with support for routed events, command binding, layout, and focus. Keyboard, Mouse, Stylus, and Multi-Touc. Visual3D is the base class for all objects that have their own 3D visual representation. Uielement3d is the base class for all 3D visual objects with support for routed events, command binding, and focus, also discussed in Chapter Instead, contentelements are hosted in a Visual-derived class to be rendered onthe screen.

Each contentelement often requires multiple Visuals to render correctly spanning lines, columns, and pages. Frameworkelement is the base class that adds support for styles, data binding, resources, and a few common mechanisms for Windows-based controls, such as tooltips and context menus. Frameworkcontentelement is the analog to frameworkelement for content. Control is the base class for familiar controls such as Button, listbox, and statusbar.

Control adds many properties to its frameworkelement base class, such as Foreground, Background, and fontsize, as well as the ability to be completely restyled. Xaml good for UI because of hierarchical nature. Logical tree exists even if there is no xaml. Properties, events, resources are tied to logical trees.

Properties propagated down and events can be routed up or down the tree. Its a simplification of whats actually going on when rendered.

Visual tree can be thought of as an extension of the logical tree though some things can be dropped as well. Visual tree exposes visual implementation details e.

A listbox is a border, two scrollbars and more. Only things from visual or visual3d appear in a visual tree. Avoid depending on visual tree in your code. We can traverse using System. Here is a code-behind file that will print these trees, assuming the gluing code is there i. Class and xmlns: Diagnostics; System.

Windows; System. Media; 5 Public partial class aboutdialog: Strings If! Navigating either can be done in instance methods of the elements themselves e. Visual class has protected members visualparent, visualchildrencount, and getvisualchild. Frameworkelement and frameworkcontentelement have Parent property and logicalchildren property. They complicates. Dependency properties depends on multiple providers for determining its value at any point in time.

These providers can be an animation continuously changing its values. A parent whose property propagates down. Arguably biggest feature is change notification. Motivation is to add rich functionality from declarative markup. Key to declarative-friendly design is heavy use of properties. Button e. Has public properties 98 inherited. Properties can be set using xaml, directly or in a design tool, without procedural code.

Without the extra work in dependency properties, it would be hard. We looked at implementation of a dependency property and then see its benefits on top of. Change notification, property value inheritance, and support for multiple providers are key features.

Understanding most nuances is important only for custom control authors. However what they are and how they work important for everyone.

Can only style and animate dependency properties. After using wpf for a while, one wishes all properties were dependency properties.

In practice, dependency properties are normal. By convention, public static and Property suffix are used. Its required by several infrastructure pieces e. Localization tools, xaml loading.

Optionally via different overloads of Register , you can pass metadata that customizes how the property is treated by WPF, as well as callbacks for handling property value changes, coercing values, and validating values.

It helps setting from xaml and isnatural. Otherwise getvalue and setvalue are to be used. Getvalue and setvalue methods inherited from System. Getvalue setvalue does not support generic. Dependency properties were introduced before generic support was added in C. Visual Studio has a snippet called propdp that automatically expands into a definition of a dependency property, which makes defining one much faster than doing all the typing yourself!

Although the XAML compiler depends on the property wrapper at compile time, WPF calls the underlying getvalue and setvalue methods directly at runtime!

If you want to add custom logic, thats what the registered callbacks are for. All of wpfs built-in property wrappers abide by this rule, so this warning is for anyone writing a custom class with its own dependency properties. On the surface, it too much code but saves per-instance cost.

Only static field and an efficient sparse storage system.It just a compressed representation of XAML. We use it as our gui example with C. Save "test-doc. Using Using Using Using. A permanently weak driver is a driver with fewer than five assignments on all the days on which the driver has been active. Clear 28 Question Types of class members in C are and. We can load from resource.
