Hello All (especially StataCorp)

I have been planning an update for the dialog of my -eclplot- package (downloadable from SSC), and have been trying to work out how to include standard comboboxes and list boxes so that the user can select marker symbols, sizes and colors. In the course of examining the Stata .idlg files mentioned in the very helpful FAQ by Jean Marie Linhart and Alan Riley, I have found frequent appearances of a COLOR command, which does not seem to be mentioned in -[P] dialogs- or even in -whelp undocumented-, and which appears to be connected with enabling the "Custom color" option in comboboxes for color selection. Is this documented anywhere? And how does it work?

More generally, is there any documentation on how to implement comboboxes and list boxes for standard frequently-used graphics options such as symbols, sizes and colors? For instance, the file -_glist_def.idlg- contains references to -contents()- specifications with names such as "symbols", "symbolsizes" and "colors". Do these refer to standard LISTs which the dialog programmer is well-advised to use, instead of defining them anew and re-inventing the wheel?

Best wishes (and thanks in advance)
