Retrieves an array of disjoint text ranges from a text container where each text range begins with the first partially visible line through to the end of the last partially visible line.
Assembly: UIAutomationProvider (in UIAutomationProvider.dll)
UI Automation providers should ensure that they return, at most, the text ranges that are visible within the container.
Disjoint text ranges may occur when any content of a text container is obscured by an overlapping window or other object, or when a text container with a multi-column layout has one or more columns partially scrolled out of view.
If no text is visible, a degenerate (empty) text range is returned. This empty range can be returned if the text container is empty or when all text is scrolled out of view.
