It's a Delphi app so they wouldn't be of much use.

All clicking on the buttons do is something like this:

Show Button
-> ComboBoxEx1.Visible := True; ComboBox1.Visible := True;
Hide Button
-> ComboBoxEx1.Visible := False; ComboBox1.Visible := False;
Enable Button
-> ComboBoxEx1.Enable:= True; ComboBox1.Enable:= True;
Disable Button
-> ComboBoxEx1.Enable:= False; ComboBox1.Enable:= False;

Both of the comboboxes are set to 'drop down list' style (so no 'edit' box).

As a side note (and not something my patch did anything about), if the
ComboBoxEx items have images, they aren't displayed in the same way as they are
in Windows.

In Windows, only the currently selected item (the one shown in the control)
uses the 'selected' image - highlighting them in the drop down list does NOT
make them selected in the sense that they should suddenly use the selected
image, which is what happens under Wine. 

Also, under Wine, when the comboboex loses focus (even just when displaying the
drop down list), the item shown in the control stops being displayed with its
selected image. That doesn't happen in Windows.

I have an updated demo where the comboboxex items have images associated with
them if you fancy tackling that issue?!
