substituting List for Treeview in combobox

[obv]

Hi All,

I' trying to create a component, very much like a lookupcombobox, only with
a treeview instead of a list.

In other words: what I want to achieve is this:
when I click on the button of the combobox, the visible dropdown-part of the
component should be a treeview(-descendant), and not a List.....

I'm descending my class from TCustomCombobox, (maybe i shouldn't, because of
the list you're getting...)

The problem is: how can substitute the dropdownlist for the Treeview (or my
own descendant of the TTreeview component)
and still have access to it...


Regards

Frans

Frans,

to use TCustomCombobox is not good idea for this task.

Just use standard edit and add button in right side. Also add popup window
that will be dropdowned with treeview. Check any freeware component where
calendar or calculator is in dropdowned popup (you'll find a lot on
torry.net) and implement there your treeview instead calendar/calculator

I've tried this with a component descending from TCustomControl.
I'm still very much in the dark as to how i can create the
dropdownwindow. In the calendar there's a Createsubclass call that
seems to do the trick, but that's with a windows common control
'SysDateTimePick32'
I don't wat a calander. I want a Treeview(descendant)

You'll understand that i want a control that seems to be without
parent (just an owner). it sortof floats.
