ITextView.DisplayTextLineContainingBufferPosition Method (SnapshotPoint, Double, ViewRelativePosition)
Formats and displays the contents of the text buffer so that the ITextViewLine containing the buffer position is displayed at the desired position.
Assembly: Microsoft.VisualStudio.Text.UI (in Microsoft.VisualStudio.Text.UI.dll)
void DisplayTextLineContainingBufferPosition( SnapshotPoint bufferPosition, double verticalDistance, ViewRelativePosition relativeTo )
- Type: Microsoft.VisualStudio.Text.SnapshotPoint
The position of the character that is to be contained in the ITextViewLine displayed at the specified vertical position.
- Type: System.Double
The distance (in pixels) between the ITextViewLine and the edge of the view. If relativeTo is equal to ViewRelativePosition.Top, then the distance is from the top of the view to the top of the ITextViewLine. Otherwise, it is the distance from the bottom of the ITextViewLine to the bottom on the view.
Negative values are allowed, which may cause the line to be displayed outside the viewport.
This method can become quite expensive if verticalDistance is large. You should avoid making verticalDistance greater than the height of the view.
- Type: Microsoft.VisualStudio.Text.Editor.ViewRelativePosition
If word wrap is disabled in the view, then the ITextViewLine corresponds to the entire ITextSnapshotLine that contains bufferPosition. If word wrap is enabled in the view, then the ITextViewLine corresponds to the portion of the ITextSnapshotLine that both contains bufferPosition and fits into the view. bufferPosition may not be the first character in the ITextViewLine. The returned value is generally equal to verticalDistance, except when the view was repositioned to prevent a gap from appearing at the top or bottom of the view. Calling this method causes the view to dispose of its current TextViewLines.
