[Newbies] wxSqueak: How/Where do I find GUI object params, e.g., for Checkbox: style: wxNoBorder

[Brooks Bridges]

I've done a lot of searching but can't find a list to
choose such things from.  

I'm looking at the code for a checkbox in the checkbox
demo.

cb1 := WxCheckBox parent: self id: wxIdAny label: ' 
Apples' position: 65 at 40 size: 150 at 20 style:
wxNoBorder.

Of course my question is general. Are these kinds of
things in pool dictionaries or what?  I don't see
anyway to do a general search in Squeak for a given
string. I don't have a clue how to proceed.

Thanks in advance,

Brooks
