hallo,
kann man irgendwo einstellen, dass das stringgrid die optimale breite nutzen soll (also quasi wie z.b. bei excel). die breite soll sich automatisch so einstellen, das der länste text so gerade darstellbar ist.

oder muss man das von hand programmieren?

danke

Delphi-Quellcode:

{! 
<summary>
 SetGridColumnWidths sizes the columns of a grid to fit their content.</summary>
<param name="Grid">
 is the grid to modify. This parameter cannot be nil.</param> 
<param name="Columns">
 specifies the columns to resize. If an empty array is passed for Columns
 all columns are sized, otherwise only those whos index is in Columns 
 are sized. </param> 
}
procedure SetGridColumnWidths(Grid: TStringGrid;
  const Columns: array of Integer);

procedure SetGridColumnWidths(Grid: TStringGrid;
  const Columns: array of Integer);

  function ColInArray(n: Integer): Boolean;
