FitHorizontal: TriState;
The FitHorizontal property determines whether images are scaled on changing cell width.
Images can be set up using the NormalPicture, HoverPicture and PushedPicture properties. By default the FitHorizontal property is set to the TriState.OffOption value. When the FitHorizontal property is set to TriState.OnOption, the images are proportionally scaled when the width of an image cell is changed.
