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

IXRBrush provides the base class for brushes in XAML for Windows Embedded. Each brush paints an area differently. Brushes can paint an area with a solid color, a gradient, or an image. The following list describes the different kinds of brushes:

IXRSolidColorBrush: Paints an area with a solid color.
IXRLinearGradientBrush: Paints an area with a linear gradient.
IXRRadialGradientBrush: Paints an area with a radial gradient.
IXRImageBrush: Paints an area with an image.

You can paint an area on the graphical window by using an IXRSolidColorBrush that uses a predefined solid color. To do this in C++ code, set a color for the IXRSolidColorBrush. For more information, see IXRSolidColorBrush.

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