Name

Description

IXRLineSegment::SetPoint

Sets the endpoint of a line segment.

IXRLineSegment::GetPoint

Retrieves the endpoint of a line segment.

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

You can use an IXRPathFigure object to create composite shapes by using IXRLineSegment objects and other segments.

The IXRLineSegment class does not contain a property for the starting point of the line. The starting point of the line is the endpoint of the previous segment or the starting point of the IXRPathFigure if no other segments exist.

You can generate a simple line by using IXRLine. Use IXRLineSegment to draw a line within a more complex geometry group.

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

You can also define an IXRLineSegment object 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 LineSegment Class on MSDN.
