 System::Windows::Rect GetRectFromCharacterIndex(int charIndex);
public System.Windows.Rect GetRectFromCharacterIndex (int charIndex);
member this.GetRectFromCharacterIndex : int -> System.Windows.Rect
Public Function GetRectFromCharacterIndex (charIndex As Integer) As Rect

Parameters

charIndex
Int32 Int32 Int32 Int32

The zero-based character index of the character for which to retrieve the rectangle.

Returns

A rectangle for the leading edge of the character at the specified character index, or Empty if a bounding rectangle cannot be determined.

Remarks

Because this method returns a rectangle that represents an edge of the character, the width of the rectangle is 0.
