Color Combobox - how to do ? [message #453879]

I spent ages for finding out how to create a combobox that can be used to
show colors instead of text (strings).

As far as I found out as beginner there is no way to subclass Combo or
CCombo in order to draw the list field (in that case different colors as
background for every item)
And I couldn't find a way to set an own List-derived class to CCombo.
I cant imagine that he only way should be to create a custom control
instead of accessing the list-values or set an own list class.

Any suggestions ?

Thanks

Holger

Hi Holger,

Combo and CCombo won't do these, so you will need your own component.
CCombo provides a good starting point, just change its popup List to a Table
that has no lines or header.

As a side note, color selection in eclipse (for example in the preference
pages) is usually exposed through a button with the color on it, so that
pressing it will bring up the ColorDialog which allows for selection of any
available color. This alternative strategy may or may not be appropriate in
your context.
