Do you want to rewrite it?

Yes. Thanks.
I already found such a bug. I will commit a fix together with a few
other fixes for the gtk2 in a few days.

This means, that either your project or one of the used packages use
the wrong macro name (TargetOS is the correct name). Probably in the
compiler options. It is not a package coming with lazarus.

Strange. Here the filter shows this message in the window.

Not really; 
I was doing some investigation for an article I'm writing,
and I simply stumbled on this strange fact :)

From a design/architectural/principal point of view, though, I 
think that it's better to have it as a TCustomEdit descendent 
as well, though. Although I have no idea how much work that would be.
So if you have nothing better to do on a rainy day...

Selected property of TChecklistbox

The Selected[] array property of TCheckListBox does not work.
(do not confuse with Checked[] array property, which does work)

Reported as bug 8796.

Do you have FBLib installed? If so, that is probably the problem. As
Mattias suggested, have a look in the FBLib compiler options and fix
it there.

I already notified the FBLib author about this issue.

Ah, I never spotted that mistake.  Because I clicked on a Toolbar
button to launch the editor toolbar config screen, I cannot rebuild
the Toolbar from the OnDestroy of the config screen. As technically, I
am still in the ToolbarButton.OnClick event.

I should be able to free off the other Toolbar Buttons though. Correct?

Correct.

Patch for TFilelistbox

Hi,

Attached is a small patch which publishes the \var{Directory} property of 
\var{TFileListBox}. While it makes little sense to set this property in 
the IDE, it does make sense to have it published:
- It can be controlled with an RTTI control.
- The FormSettings mechanism can save/restore it.
