[c#] event handler for tracking cursor location

Hi John,

I do not want to set up a privative or dgnelementset as i want to track the cursor location while the user is using an existing tool.

it's not how MicroStation API works. You can track cursor movement in dynamics mode in your own command, but not in others.

To be precise, I assume you can do it in C++ API monitoring input queue, but it would not be simple task.

any help or push in the right direction??

What (and why) do you want to achieve?

With regards,

In PowerGEOPAK there was something called active chain control and curvilinear coordinates. that would provide that station/offset/elevation from where your cursor is but it was not a "tool" so it would keep running while using other tools. this video gives a quick overview.

now in OpenRoads Designer there are some things that offer close to similar functionality, i was just seeing if it was something that could be created or not.

sounds like it might not be worth it.

Nice and explanatory video.

I guess it can be done, but C# is not the right tool. In C++, there are much more options what can be monitored.

I mentioned the option to monitor input queue, but there is also SetMotionFunction callback available. I did not try to implement such monitoring, so I am not sure what option is the best.

as always thanks Jan,

probably going to let this idea go for now.
