Is something like this possible with GEF [message #206702]

All,

Has anyone done something similar to the graphical editor below

http://www.silabs.com/tgwWebApp/public/web_content/products/ Digital_Power/Digital_Power/en/Digital_Power_Tools.htm

I am more interested in the Compensation Editor. If someone has a similar
tutorial, it would be much appreciated.

Thank you,
Harsh

Also,

Do we have connections that have pivot points? Is something like that
built in to GEF?

Thank you,
Harsh

You can definitely create that type of Editor using GEF. I can't say exactly
because I'm not sure what things are related in that screenshot, and how
they are used. Is everything manually placed in that diagram? Connections
can have editable children on them, and you could allow those children to be
dragged around.

Here's a question maybe you could answer. What's the best way to drive a
10-ohm load, between 6 and 10.5 volts, using a 12-volt power source. The
load's voltage should vary appox linearly based on a PWM signal. My idea is
to create an RC filter feeding an OpAmp, which feeds a power transistor. I
was thinking of another solution using an LM317.

Randy,

Thanks for your response. Everything doesn't have to be placed manually.
For example, the Connections could have a property defining the # of
editable labels needed and then we display them accordingly as child
objects of the Connection.

The main difference I see here which I haven't seen before in GEF are
pivot points within connections. The user requirement is to move the
connection around objects manually. I know today in GEF, the ShortestPath
conenction is based on Dykstra's algorithm (correct me if I am wrong).

Everything else should be doable with some effort, like rotating figures
so the current flow is more intuative.

Randy, not sure if you can comment on this right now, but what type of
things can we expect with the animation enhancements in the latest GEF
release? Sticking with this example, it would be nice to show current
flow from the voltage source to ground.

Regards,
Harsh
