Well, sorry, but no, properties still don't work....

But, now there is a way to see the contents of your StringList. (Using
FpDebug and Dwarf-3 / other Dwarf versions should work too)

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Project1;uses Classes;var  MyList: TStringList;begin  MyList :=
TStringList.Create;  MyList.Add('abc');  MyList.Add('123'); 
MyList.Add('Foo'+LineEnding+'Bar');  MyList.Add('whatever');end.
In the watches window (or debug-inspect / evaluate) add this:
Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
MyList.FList^[0..3].FStringAnd see the image for the result.

I tested with Lazarus trunk (main branch) and with fixes_3_0. It works
here!
However I don't know what the arrow buttons are supposed to do.
Clicking them makes no difference.
The "+" and "-" buttons change the number in between them, but what is
its purpose? The range is already given by a user.

Anyways a nice feature.

They are for any array, but only do something if there are more than
10 entries.

Then you see a page of 10, and can go through the pages.

The +/- change the size of the page.

OK, sounds like a useful feature for some advanced debugging
situations. I must test it further at some point.
