Two problems with Combobox - text color and height
«

Hello everybody
I have problem with ComboBox. For example I have like this:
(https://s15.postimg.org/l5253hjpj/Bez_tytu_u.png)
I set color of font to red, but all my items are black? What i do wrong?
Second question: Can I resize the white field with my items, I'm talking about height this field. When I have much more items, this field is too small in height direction.

Code: Pascal
[Select]
[+]
[-]
ComboBox1
.
DropDownCount
:
=
20
