First, thanks to Mark River and Xihui Chen.  I will add interfaces
to the plugins in the future, when I have more time.

Bruce Hill wrote :

We've had similar requests here at SLAC.   We use TwoDProfileMonitorClass
with EDM for our cameras, and are looking for an easier way to select
the region of interest.   We looked briefly into doing a Python/QT camera
viewer with this feature, but haven't had time to get serious about it.


If anyone has a solution for this, we'd be interested in hearing about it.

Attached is the implementation in the TwoDProfileMonitor.cc and video.edl. For now, it only shows the cursor and displays the X,Y locations of the cursors. By doing the one click action on the mouse(ie. oneClickAct PV), it will automatically define the upper left corner of the ROI. The width and height has to be defined in advance manually. For now, the implementation of the cursor location and one click act is enough for us.


Cheers, Kate
