Change Style problem in ulp code

Former Member

Hello, I am trying to make a dotted wire in ulp code using  e.g.  cmd = "CHANGE STYLE WIRE_STYLE_SHORTDASH" but the wire stays as a continuous line. Any idea how to make CHANGE STYLE work ? 

Thank you,

Bob

 

// run this file as a .ulp file

// Problem: CHANGE STYLE doesn't work as expected

// Q. how to make the line be drawn as a dotted line ??

 

string cmd = "";

 

real x1 = 10.0;

real y1 = 10.0;

real x2 = 50.0;

real y2 = 50.0;

 

sprintf(cmd, "The number is %d", WIRE_STYLE_SHORTDASH);

 

dlgMessageBox(cmd); // just confirms that WIRE_STYLE_SHORTDASH = 2

 

cmd = "";

  

cmd = "CHANGE STYLE WIRE_STYLE_SHORTDASH"; 

  

cmd = cmd + "\n";

 

sprintf(cmd,"WIRE 1 (%f %f) (%f %f) ;", x1, y1, x2, y2 ); 

 

cmd = cmd + "\n";

 

cmd = cmd + "Window Fit;\n";

 

exit(cmd);

    Hi Bob,

     

    Aren't you overwriting cmd in your final sprintf()? It looks to me like the only thing passed in cmd to exit() is the actual wire and not the style information.

    That made me take a closer look.  I added a missing ';' after wire_style_short_dash, and modified the code, but still no luck :-(

    Happy to try anything else ...

     

     

    //--------------- latest attempt ------------------

    string cmd = "";

    string temp = "";

     

    real x1 = 10.0;

    real y1 = 10.0;

    real x2 = 50.0;

    real y2 = 50.0;

     

    sprintf(cmd, "The number is %d", WIRE_STYLE_SHORTDASH);

    dlgMessageBox(cmd); // just confirms that WIRE_STYLE_SHORTDASH = 2

    cmd = "";

     

    cmd = "CHANGE STYLE WIRE_STYLE_SHORTDASH;"; 

     

    cmd = cmd + "\n";

     

    sprintf(temp,"WIRE 1 (%f %f) (%f %f) ; ", x1, y1, x2, y2 ); 

     

    cmd = cmd + temp + "\n";

     

    cmd = cmd + "Window Fit;\n";

     

    exit(cmd);

    Hi Bob,

     

    You are right it still won't work doing it that way. I should have thought on this a little more before my last comment although that was still an issue in your ULP which needed correcting. Ignoring ULP for a second, if you just issue the CHANGE STYLE WIRE_STYLE_SHORTDASH; command in the editor window you will see it has no effect on the next wire that is drawn. It only works this way if you skip the semicolon and then select the option from the menu (which defeats the purpose of typing the desired style into the command). I'd suggest playing around with the commands in the editor first and see if you can work out a sequence of commands which does what you need and then write your ULP to create those commands.

     

    Best Regards,

    Hi Bob,

     

    Okay so I have just had another quick look at this and the problem is that the style name is not WIRE_STYLE_SHORTDASH when used with this command. That is one of the constants used for the style attribute of a UL_WIRE object. It's simply SHORTDASH with the CHANGE command. If you issue the command:

     

    CHANGE STYLE SHORTDASH; WIRE (0.0 0.0) (5.0 5.0);

     

    You will see a dashed wire is drawn.

     

    Best Regards,

    That's wonderful !!

     

    It now works.

     

    I changed my code to:

     

    cmd = "CHANGE STYLE SHORTDASH;\n";

     

    So happy.

     

    Thanks very much.

     

    Bob.
