Skill: How to run procedure upon the path draw?

dell1

Dear All,

I need to run certain procedure after the user click the first point to draw a path (using the "<Key>p" binding key).

Is there a way to do that in Skill?

 Thanks

  • There's not really a general way of doing this, but something like this could be used:

    procedure(ABpathIntercept()
      mouseAddPt(t)
      when(hiGetCurrentCmd(hiGetCurrentWindow())=="Path"
        printf("POINT WAS %L\n" hiGetCommandPoint())
      )
    )

    hiSetBindKey("Layout" "<Btn1Down>EF" "ABpathIntercept()")

    The trouble is knowing which is the first point - there doesn't seem to be an API to know that directly. Maybe using changeEnterFun, but you'd have to know what the function that is being called for create path is, and I think that's done at the C level. One way would be to keep a list (would have to be per window though, so maybe as a property on the window, or in a global table), and then wrap the bindkey for create path so that it resets the list. Then you'd also have to change the bindkey for backspace so that it removed the last point (to allow the first point to be reentered). So it gets messy very quickly. And infix would be a different problem.

    Just tryng to point out that the above would be an imperfect solution.

    Regards,

    Andrew.
