Multiselections in list boxes?

It's posible to multiple selections in list boxes in VB, is it posible in blitz too? If so, how do you code that?

I take that this is just not possible in Blitz Plus?

Not that it is the most elegant solution, but this weekend I coded my own enhanced listbox using canvases, and it rox! Imagine having several columns, with text, numbers and checkmarks (which you can set on/off by clicking on it) and imagine having all different colors in it. It takes a while to make such a personalized listbox when you do a one-shot app, and probably much longer before it's a really seperate tool, but then you surely have a first-class listbox..

So instead we must be asking for ways to access Windows system colours..! (Otherwise, the colour scheme of your listbox will be wrong on computers with non-standard colour schemes.)
