I'm making a GUI that controls some custom hardware using MATLAB. Since many of the parameter fields are highly technical, I'm using tooltips to give more detailed descriptions of each of the fields. Most of my fields look something like this:
Because of how MATLAB GUIDE works, the label, entry box, and units are all separate entities with separate tooltips. I am wondering, which object should have the tooltip? The entry box? The label? All three? The main downside to using multiple objects is that there is a slight gap between them, so the tooltip would disappear and reappear when moving the cursor over the gap.
