ITextProvider2 Interface
Definition

Extends the ITextProvider interface to enable Microsoft UI Automation providers to expose textual content that is the target of an annotation or selection. Implement this interface in order to support the capabilities that an automation client requests with a AutomationPeer.GetPattern call and PatternInterface.Text2.

Remarks
For more info on this pattern, see Text and TextRange Control Patterns.
ITextProvider, ITextProvider2 and ITextRangeProvider aren't implemented by any existing Windows Runtime automation peers using this definition of the interface. The text models supported by Windows Runtime text controls such as TextBox and RichTextBlock do implement some of these patterns, but do so at a native level that doesn't appear in the Windows Runtime definitions of the API surface. For more info, see the peer classes for the various Windows Runtime text controls.
The ITextProvider2 pattern doesn't have a Windows Runtime property identifier class.
Interface inheritance
ITextProvider2 inherits ITextProvider. Types that implement ITextProvider2 also implement the interface members of ITextProvider.
Properties
| DocumentRange |
Gets a text range that encloses the main text of a document. (Inherited from ITextProvider) |
| SupportedTextSelection |
Gets a value that specifies whether a text provider supports selection, and if it does, the type of selection that is supported. (Inherited from ITextProvider) |
Methods
| GetCaretRange(Boolean) |
Retrieves a zero-length text range at the location of the caret that belongs to the text-based control. |
| GetSelection() |
Retrieves a collection of disjoint text ranges that are associated with the current text selection or selections. (Inherited from ITextProvider) |
| GetVisibleRanges() |
Retrieves an array of disjoint text ranges from a text container. Each text range begins with the first partially visible line and ends with the last partially visible line. (Inherited from ITextProvider) |
| RangeFromAnnotation(IRawElementProviderSimple) |
Exposes a text range that contains the text that is the target of the annotation associated with the specified annotation element. |
| RangeFromChild(IRawElementProviderSimple) |
Retrieves a text range that encloses a child element, such as an image, hyperlink, or other embedded object. (Inherited from ITextProvider) |
| RangeFromPoint(Point) |
Retrieves a text range from the vicinity of a screen coordinate. (Inherited from ITextProvider) |
