Class: TEgFireGrid
property AutoColumnAll: Boolean default False;When True, every visible column takes a share of the
width difference that AdjustColumnWidth
distributes, in proportion to its current width, instead of only the
column at AutoColumnIndex.
What the proportional shares leave over, a fraction of a unit, goes to
the widest column.
It works only together with AutoColumnWidth:
setting it to True while AutoColumnWidth is
False is ignored (as in TEgDBGridEx). Turning
it on while AutoColumnWidth is on adjusts the columns at
once.
