问题
I prefer buttons with minimal margins, about as wide as their text caption. Is there a way to achieve that in a JButton in Swing?
What I am seeing in practice now is that even if I try to use setMaximumSize() and similar, it just ends up eating the text caption, cutting it off to the right. But it does not reduce the margins.
回答1:
I believe setMargin is what you're looking for.
myButton.setMargin(new Insets(0, 0, 0, 0));
回答2:
Worth noting you can make the values for Insets -ve. This makes things even more compact and if done carefully doesn't look unpleasant.
