Comment out "eventdata" with "~" in GUI
显示 更早的评论
guide suggests replacing "eventdata" in callbacks with "~"; is this wise? If I don't do it, M-lint will always show orange!
Thanks.

You can, but you'll still have another orange squiggle on the line. It will still say that the callback function might not be used. Duh! It's a callback, and won't get used unless someone interacts with the control it's associated with. You can suppress warnings, but I didn't suppress that warning because what if there is some dead code function somewhere in your code that you custom wrote (not a built-in callback generated from GUIDE)? I'd like to know about those unused functions. However I have so many of these callbacks that my right margin is just a virtual barcode of orange and gray stripes, so I tend to ignore them on the margin.
If it's in the code window (text editor) and it's a valid suggestion, then I will take corrective action, but I ignore most on the right panel because there are simply too many.

You can if you are not using that variable in rest of the function. The '~' doesn't work in the older versions though( R2006b or R2007a, i believe, will chk and edit this).
