They became enabled when there is data to work on.
For example type or select a new path on the edit line just above the buttons and you can add it to the list.

Does it work for you?

@Juha, you are right, if you enter something to the edit line buttons became enabled, but if you choose or click the directory icon and select the directory, they dont become enabled.

Then it must be a bug in OS/X Carbon bindings.
For me it works with QT and GTK2 bindings and IIRC it works with Windows bindings, too.

The control is TShortPathEdit, inheriting from TDirectoryEdit and TCustomEditButton.
Its OnChange event handler updates the buttons like this:

 procedure TPathEditorDialog.DirectoryEditChange(Sender: TObject);

Apparently the OnChange event is not fired on Carbon.
Could you please look for related issue reports and create a new one if there is none.
I don't have a Mac to test with.

The ListBox OnSelectionChange event handler also updates the buttons :

 procedure TPathEditorDialog.PathListBoxSelectionChange(Sender: TObject; User: boolean);
   FullPath : String;
   with PathListBox do
     if ItemIndex>-1 then begin
       FullPath := Items[ItemIndex];
   UpdateButtons; <- here it updates the buttons

There was a bug some time ago but it works well in recent trunk versions (for me).

Can other Mac users reproduce this?

I looked at the code in the 'patheditordlg.pas'. The given source is the same.

> So?

I don't have a Mac to test with. Maybe you could isolate the problem with events into a simple test application and make another report.

Now it is working but there is also another case which is related with this issue. Do I open another issue or add the problem in here?

It is better to open a new one. We can make it related to this one.
Somebody with a Mac must take care of it.

You can try it and provide a patch if it works. It should be tested with other widgetsets, too, not only with Carbon.

Alexey, I added it inside an IFDEF. This is considered a temporary fix. A proper fix must go to the control itself.
