I'm writing a GUI layer on top of Photon on QNX4 and on NTO 6.5 (cannot use PhAB) and am having some issues that I'm 
hoping someone can help with.

1) Is there a document that assists with porting from QNX4 Photon (1.14) to Photon in NTO 6.5? eg documenting things 
like PtCreateWidget() crashes if the parent is NULL

2) I'm getting a return value of NULL when trying to create a PtGroup widget under NTO 6.5 which worked fine in QNX4.  
How can I determine why the widget wasn't created properly? ie I can't find any API call that gives me the error code or
 text for why PtCreateWidget() returns NULL

3) Where did the PtHtml widget go?

As I'm still in the process of building this GUI layer on both QNX4 and on NTO, is there any repository of sample code 
that uses Photon (without PhAB) for doing things like handling PtTab widgets for switching display of pages in a 
notebook style widget?

Another QNX4 question.  How does one create a dialog without PhAB?

Thanks for any assistance.  I'm sure there will be more to come...

Cheers, Mark
