Dear All,

caQtDM and epicsqt have a different philosophy concerning the data io. caQtDM uses pure graphics objects that are populated by the caQtDM viewer. Epicsqt uses epics aware widgets, i.e epics is sitting underneath the widgets. Epicqt can view therefore the variables in the designer and the graphical widgets of caQtDM cannot. The two packages can be concurrent, while they consist of plugins for the designer. The viewer of both packages can thus use both widget sets. It is already some time ago that the integration of both widgets took place. It is however not impossible that after a year, things diverged. I think that related displays are not (well?) supported by the epicsqt viewer (Andrew, please correct me). If you use this feature of caQtDM, then use the caQtDM viewer and plugin the epicsqt widgets.

I hope this explanation helps you.

==================================

Hi Anton,
Indeed, that provides some background as well as clarification.
We will a more questions as go further into the collaboration.

PS:  I am trying to build QT5  from source but ran out of disk quota :(
Gotta find another disk partition with more space.  :)

Cheers,
Ernest

Best regards

Anton

Hi Guys,

Can you tell us a bit about the Channel Access interface you have for your package?
Is it the same for both  "caQtDM" and "epicsqt" ?
If not, how is it different?


Thanks in advance for your time.


Cheers,
Ernest
