Macro: cancel button & set scale

[ben.s.carlson]

Hello,

I have two questions regarding the macro language.  After some searching and experimentation, I can't find the answer so I'm wondering if anybody can provide assistance.

I have a somewhat interactive macro in which there are several waitForUser prompts that request that the user takes some action.  

1) I'm wondering if there is some way to add a Cancel button to the waitForUser prompt.  I'd like to do this because if the user makes a mistake and has to start over, there is no way for them to do so.  Instead, they just have to click "OK" on the many prompts that appear until the macro finishes.

Here is a small snippet.  Can I add Cancel buttons to these prompts?

waitForUser( "Pause","Focus on the ruler");
setTool("line");
waitForUser( "Pause","Draw a line and set scale");

2) The second is related to the request to "set the scale" above.  Is it possible to automate this so that the user is not required to click Analyze -> Set Scale?  The "Distance in Pixels" value is always the length of the line the user just drew, "Known distance" is 1.0, and "Unit of length" is cm.  This seems like it is something that can be automated.

Thank you for the help!

Ben

You can cancel a waitForUser dialog and abort the macro by pressing the esc key.

This should do it:

  getLine(x1, y1, x2, y2, lineWidth);
  if (x1==-1)
     exit("Stright line selection required");
  dx=x2-x1; dy=y2-y1;
  length = sqrt(dx*dx+dy*dy);
  setVoxelSize(1/length, 1/length, 1, "cm");
