Figure 9-19. Different configurations of the linear gradient brush Figure 9-19 shows the behavior of several different options for the linear gradient brush. The default behavior is shown first, spreading from black to white. Here s the XAML for this gradient: <Rectangle Stroke="Black" Width="60" Height="60"> <Rectangle.Fill> <LinearGradientBrush> <GradientStop Color="#FF000000" Offset="0.0"/> <GradientStop Color="#FFFFFFFF" Offset="1.0"/> </LinearGradientBrush> </Rectangle.Fill> </Rectangle> The following code shows how to spread the gradient horizontally instead of diagonally: <Rectangle Stroke="Black" Width="60" Height="60"> <Rectangle.Fill> <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5"> <GradientStop Color="#FF000000" Offset="0.0"/> <GradientStop Color="#FFFFFFFF" Offset="1.0"/> </LinearGradientBrush> </Rectangle.Fill> </Rectangle> The next code block creates a gradient that spreads to the center point of the gradient line and a second gradient that spreads from the center point to fill up the other half of the surface:

In this case, the registerClass method call passes the fully qualified name of the class, the class it inherits from, and the interface it implements. You can implement more than one interface with your class simply by specifying each interface into the registerClass method and separating the interface s name by a comma. Conversely, an imitation sports car is just a fancy-looking normal car, so its class definition would look like this:

The foreach statement allows you to sequentially access each element in an array. It is actually a more general construct in that it also works with other collection types but this section will only discuss its use with arrays. 20 will cover its use with other collection types. The important points of the foreach statement are the following: The iteration variable is a temporary, read-only variable of the same type as the elements of the array. The foreach statement uses the iteration variable to sequentially represent each element in the array. The syntax of the foreach statement is where Type is the type of the elements of the array. Identifier is the name of the iteration variable. ArrayName is the name of the array to be processed. Statement is a simple statement or a block that is executed once for each element in the array. Iteration variable declaration foreach( Type Identifier in ArrayName ) Statement The way the foreach statement works is the following: It starts with the first element of the array and assigns that value to the iteration variable. It then executes the body of the statement. Inside the body, you can use the iteration variable as a read-only alias for the array element. After the body is executed, the foreach statement selects the next element in the array and repeats the process. In this way, it cycles through the array, allowing you to access each element one by one. For example, the following code shows the use of a foreach statement with a one-dimensional array of four integers: The WriteLine statement, which is the body of the foreach statement, is executed once for each of the elements of the array. The first time through the loop, iteration variable item has the value of the first element of the array. Each successive time, it will have the value of the next element in the array. int[] arr1 = {10, 11, 12, 13}; Iteration variable declaration Iteration variable use foreach( int item in arr1 ) Console.WriteLine("Item Value: {0}", item);

Often, developers will update their apps for the iPod touch. You don t need to use your computer to perform the update you can do it right on your iPod touch. You can even tell if you have updates, and how many, by looking at the App Store icon. The one shown here has five app updates available for you to download. Once you enter the App Store, tap the right-most icon on the bottom row. This is the Updates icon.

Figure 11-4. Create a Style from your Rectangle called GradientButtonStyle. Blend then wraps your Rectangle into a Grid, along with a ContentPresenter (which displays the Button s Text). You are still in MainPage.xaml, but you are actually editing the GradientButtonStyle. You can see this by looking at the top of the Visual Tree in the Objects and Timeline panel, where it says GradientButtonStyle (shown in Figure 11-5), or by the breadcrumb control that says [Button] Template (shown in Figure 11-6).
