Displayed columns in the TJamShellList
Frage / Problem
How can I select the columns that are (initially) displayed in the TJamShellList?
Antwort / Lösung
Each Windows Shell extension may define which columns will be displayed for its view.To add or remove specific columns, use the OnCreateColumns event in combination with SetColumnVisibility. 
Example: 
uses ShellBrowser; 
procedure TForm1.JamShellListCreateColumns(Sender: TObject); 
begin 
   with JamShellList do 
   begin 
       SetColumnVisibility(TShellColumns.Size, False); 
       SetColumnVisibility(TShellColumns.Author, True); 
    end; 
end;
