Is there some documentation that explains the difference between inputWidth and Width for a button?
Should I be defining both values for each button on a tollbar, or is it only necessary to define one or the other?
Normally you need to define only width
width - size of container for the button
inputWidth - size of actual button
Normally inputWidth is equal to width ( automatically ), but in some cases you may want to have wide container but smaller button inside, in such case it has sense to define both width and inputWidth
