for the patch I am making (but I think it would be useful to all), it  
would be very nice if it could be detected when the value of a float is  
changed by click+dragging with the mouse. That means, not in edit mode.  
Would maybe a detector for the changes of values be possible?

something nice, if possible, would be also a "click-detector", or a  
variable which would respond to when the user clicks on a struct, like a  
bang. again, these two objects would be not in edit mode. I think would be  
important, in case the patches would be handled only by "users", i.e., the  
persons that didn't programmed the patch.

keep up the good work,

Joao
