[solved] which checkbox was clicked in TCheckListBox ?
«
on:

I'm using a TCheckListBox and want to know which one the user has just clicked. On Win/Linux clicking a checkbox also selects that item so you can look at ItemIndex when CheckListBox1ClickCheck fires. But on the Mac the selected item does not change when a checkbox is clicked.
I'm not sure if I should rely on that connection anyway, its certainly not documented anywhere that clicking a checkbox should select that item.
I can keep a separate list of which ones are ticked and then scan over the listbox and see which one has changed but that does seem messy !
Does anyone else know of any way to get an index to a clicked checkbox on TCheckListBox ?

Yes, OnItemClick is the way + you can fill bugreport (if it is not already reported).

Yep, thanks, thats definitly the solution. I just needed to search a bit harder !
I'll put something on the TCheckListBox wiki page, sadly its almost blank.
