Cocoa: TListView does not show GridLines

Original Reporter info from Mantis: crlab @neurolabusc1

• Reporter name: Chris Rorden

Description:

The TListView has a property "GridLines" that toggles whether grid lines are visible. Unlike other widget sets (Windows, GTK2), this property has no influence on Cocoa, where gridlines are never shown.

NSTableView has these 2 properties that could be implemented in order to show grid lines in TListView:

 NSTableViewGridLineStyle gridStyleMask;
 NSColor *gridColor;

This is a cosmetic issue, but if it is easy to include it would be nice.

Steps to reproduce:

Put TListView on form, set GridLines property to true - note no grid lines are drawn. I have attached an example project with a screen shot from Windows.
