I am trying to use a combobox as a container for recently used IP addresses for easy selection by the user.
I can set the combobox style to csDropDown and Sorted to true. But I cannot find the duplicates setting so I can set it to unique...

Is there some other way to do this except by loading the data on startup into a TStringList with sorted and unique set and then transfer the content into the Combobox?

I just tried TStringList(ComboBox1.Items).Duplicates:=dupIgnore; but it does not work for combo (in Qt4).

Override Insert and check if it is already in there?

It is going to be simpler to just use a TStringList container while reading from the ini file because it can be set for sorted and dupignore.
Then at the end just assign the stringlist to the combobox text property.

combobox.items.text := stringlist.text;

combobox.items.text := stringlist.text;

combobox.items.assign(stringlist)?
