Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

The IXRTextBlock object is the primary element for displaying text in XAML for Windows Embedded-based applications.

Note

Leading or trailing white space is not preserved when you set the Text property by calling IXRTextBlock::SetText.

You can align the IXRTextBlock object within the layout of the window by using IXRTextBox::SetTextAlignment, and the inherited methods IXRFrameworkElement::SetVerticalAlignment and IXRFrameworkElement::SetHorizontalAlignment.

The IXRRun and IXRLineBreak objects in the visual tree represent the <Run> and <LineBreak> XAML elements, which are used to render formatted text. These XAML elements are parsed into objects at run time by XAML for Windows Embedded. The IXRRun object is a text element that represents a discrete section of formatted or unformatted text. The IXRLineBreak object represents an explicit new line in an IXRTextBlock. If these XAML elements are used to define inner text, the corresponding run-time objects can be accessed from the inlines collection that is retrieved by IXRTextBlock::GetInlines.

When you create a class instance, use an IXRTextBlockPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can also define a text block in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the TextBlock Class on MSDN.

When you set text in a XAML <TextBlock> element instead of using IXRTextBlock to do it, it is not necessary in XAML to explicitly specify the Text property. You can put text in the <TextBlock> element as its content, or as inner text. For more information about how to set a text block in the source XAML for your application, see the Microsoft Silverlight 3 documentation.
