[Gambas-user] Settings file - preserver comments

[Bruce Steers]

2 Corrections...

1:  *SetSlotTitle(Title As String)      *should be  *SetSlotTitle(Slot As
String, Title As String)*

2: when testing i commented out line 155 of Settings.class to force a save
and forgot to un-comment it before posting.
*'  If Not $bModify Then Return*
So just uncomment out that line on the last attached version or settings
will always save even if no changes.

Or use the updated version attached to this mail with a slightly better
test gui.
Additions:
*SetSlotTitle(Slot,Title)* , *Title* is now Optional, if omitted it deletes
the comment.

bugs:
Settings.Reload() will not refresh Settings.Title if it already exists as
it thinks it's been explicitly set.
 (just call *Settings.Title = ""* before running Settings.Reload() if you
want it to)

I'll leave it with you Chris to get it working just how you want it now :)

All the best
BruceS
