# Hi everybody,<br># Today, I wanted to start to make a GUI object to create envelopes easily. I gave it the name "envgen" and immediately saw that there is already an [envgen] in pd-extended, which does exactly what I mean! So, who says finding an external is harder than writing the external itself :-)
<br><br># in the help file it says that its arguments are:<br>"xsize ysize xmax ymax send_symbol receive symbol"<br># but as I used it, this information is incorrect. Yes, 1. and 2. arguments determines the size on the screen but the difference of 3. - 4. arguments determines the ymax and I couldn't figure out how to set the xmax value. Do someone know about it?
<br><br># And I want to thank to who have written this external. Its very fundamental and impossible to implement with standart pd, because there isn't a native object to get the mouse coordinate and button status, in order to create a new point when clicked with mouse on a canvas. (But I remember that I saw one implementation of envelope generating GUI using data structures and GOP, which needs a bang to put a new point on the line graph. But I forgot its name. I have [s-varseq] abstraction of the same author.)
