Class: TEgFireGrid
property IndicatorWidth: Single;Width, in FireMonkey units, of the indicator gutter, the fixed column
at the left of the rows. The default is 16; negative values are ignored.
The gutter is shown only with egoIndicator in Options (on by
default), and stays in place while the rows scroll sideways.
As in the VCL grid, the gutter shows the state of the active row: an
arrow, an I-beam while the row is being edited, or a plus while it is a
new row not yet posted. With egoMultiSelect every selected
row shows a disc, a click on the gutter selects its row as a click on a
cell does, and on a touch screen a tap or a long press there starts the
selection (see TouchSelection).
Above the gutter, the corner cell can show an icon (CornerImageIndex).
