M:Microsoft.UI.Text.ITextRange.SetIndex(Microsoft.UI.Text.TextRangeUnit,System.Int32,System.Boolean) |
winrt method |
Moves the text range to the specified unit of the story.
The unit used to move the text range.
The index of the specified unit. The text range is relocated to the unit that has this index. If unit is positive, the numbering of units begins at the start of the story and proceeds forward. If negative, the numbering begins at the end of the story and proceeds backward. The start of the story corresponds to index = 1 for all existing units, and the last unit in the story corresponds to index = – 1.
Indicates how to change the text range. True extends the text range to include the unit by moving only the end position of the text range. False collapses the text range to an insertion point and then moves the insertion point. The default value is false.
This method allows an app to work with line-oriented text, such as source code listings, in a convenient way. For example, ITextRange.SetIndex(Line, 10, 0) converts the text range to an insertion point at the start of the tenth line.
