App Builder PtFSAllItems example?

hi, as i days before im new in QNX, basically i made my GUI in app builder, and is very small, the big part is in C++, and no major problems there, but in my app builder part, i would like to ask if any of u can share a litlle example of the use of PtFSAllItems or PtFSSelect, cause i need to select items in my PtFileSelect with buttons not with the mouse.

or an example of PtFSAllItems should be usefull, thanks in advance
