Thanks for the reply.
Yes, on Windows, Lazarus and Delphi 7 behave the same. Except that
Delphi 7 doesn't have the ListBox.SelectionChange event:
Lazarus Win platform: Edit.Exit always fires before ListBox.OnClick (and
OnSelectionChange), no matter if the ListBox item is selected or not.
Good. Though I would not expect SelectionChange to fired since there is
no change in selection?
Problem is with Lazarus Linux GTK2. Events behave the *opposite* to
Windows Lazarus and Delphi 7:
1) SelectionChange does not fire when clicking an already selected item.
I might be wrong, but thats good I think and the windows implementation bad?
2) Edit.Exit fires BEFORE ListBox.OnClick if selecting and already
selected ListBox item. Good.
3) Edit.Exit fires AFTER ListBox.SelectionChange and ListBox.OnClick if
selecting a different ListBox item than the currently selected one. Bad.
So the behaviour is inconsistent between platforms, and also
inconsistent within the same control (TListBox) depending on what item
is selected.
