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
An IXRProgressBar control inherits from IXRRangeBase and indicates progress of a lengthy operation by displaying one of the following styles:
- A bar that displays a repeating pattern.
- A bar that fills itself incrementally, based on a value.
The value that you provide in IXRProgressBar::SetIsIndeterminate determines the appearance of the progress bar.
Call IXRProgressBar::SetIsIndeterminate with a value of true to display a repeating pattern.
Call IXRProgressBar::SetIsIndeterminate with a value of false to fill the bar incrementally, based on a value. When you specify false, you must indicate the range by using the inherited methods IXRRangeBase::SetMinimum and IXRRangeBase::SetMaximum. You must call the inherited method IXRRangeBase::SetValue every time the progress value changes to determine the percentage of the bar that is filled at a given time.
When you create a class instance, use an IXRProgressBarPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
You can also define a progress bar 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 ProgressBar Class on MSDN.
