Hi, I’m new to programming in QNX and I’m looking for a graph widget that
has XY axis and a scrollable grid (meaning that as I scroll to the left or
right the gridlines moves with the data as opposed to being fixed to the
axis).
I looked at the PhAB widgets RtTrend and PtTrend but they didn’t seem to
have the functionality that I need. Due to my limited experience with QNX I
don’t know how to create my own custom widget. If RtTrend & PtTrend don’t
have the functionality does anyone know where I might find a widget that
comes close to what I’m looking for?
I’m also looking at the Tilcon software. It looks pretty nice but I’ve found
that it’s a little buggy while developing. The graphing capabilities look
really nice though, I also like the fact that I have complete control over
the software. Has anyone had any good/bad experiences with Tilcon that
they’d like to share?
Anyone suggestions/comments welcome.

Encapsulating code in a Widget is probably a lot more
difficult than just writing the code to create the graph.
Basically you want a RAW widget to draw on with lines and
other PgDraw primitives. The RAW widget has a call back
for re-drawing the graph when an expose event occurs.

There is a basic PtBarGraph widget in /qnx4/phtk/src/contrib which you can
add to your toolbar and use within Phab but it doesnt suport scrolling or
anything useful like that. I couldn’t get any replys for request for
documentation/information on it, but it could be useful for modiying to
create your own custom widget.

Dan, you probably will not get any “bad” experiences with Tilcon
posted here. It’s generally considered somewhat inappropriate to
trash a vendor in a public forum like this unless they are doing
something really inexcusable. I recall there being an article in a
recent QNX News where a company used Tilcon with good results (from
memory, I think it was Physiometrix, and they were using it in a
surgical anaesthetic dosing machine).
