Methods

Method	Description
IXRControl::AddIsEnabledChangedEventHandler	Attaches a delegate to the IsEnabledChanged event for this control.
IXRControl::Focus	Attempts to transfer the UI focus to this control.
IXRControl::GetBackground	Retrieves a brush that paints the background of this control.
IXRControl::GetBorderBrush	Retrieves a brush that defines the border background of this control.
IXRControl::GetBorderThickness	Retrieves a value that describes the width of the frame surrounding this control.
IXRControl::GetFontFamily	Retrieves the font that is used to display text in this control.
IXRControl::GetFontSize	Retrieves the size of the text in this control.
IXRControl::GetFontStretch	Retrieves a value that indicates how much a font is condensed or expanded on-screen.
IXRControl::GetFontStyle	Retrieves the style in which the text is rendered.
IXRControl::GetFontWeight	Retrieves a value that indicates the density of a typeface, as measured by the lightness or heaviness of the strokes.
IXRControl::GetForeground	Retrieves a brush that paints the foreground of this control.

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 IXRControl class is the base class for many of the controls that you add to an application, such as an item control or a text-box control. Each of these controls uses a control template to define their appearance.

You can define a control template in the source XAML for Windows Embedded XAML for your application. 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 ControlTemplate Class on MSDN.

When the source XAML is parsed into a visual tree, this control template is represented by an IXRControlTemplate object.

The methods IXRControl::GetTemplate and IXRControl::SetTemplate are used to specify the appearance of an IXRControl object. These methods access an IXRControlTemplate object that defines the appearance of the control.

If you want to change the appearance of a control yet keep its functionality, you might consider creating a new control template for an IXRControl object, instead of creating a new control class.

IXRControl has a derived class, IXRUserControl, that is the intended intermediate base class for quickly creating custom controls. Although IXRUserControl inherits the template from the IXRControl class, you cannot apply an IXRControlTemplate to an IXRUserControl. You can include other UI elements in an IXRUserControl, even other controls such as IXRButton.

If you want to create a control with custom behavior, your control can inherit from IXRCustomUserControl; however, this control also cannot use an IXRControlTemplate.

To create a custom XAML tag, use the functionality provided by IXRApplication::RegisterXamlObject and PFN_CREATE_XAMLOBJECT.

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