See No Wrap Text Pane.
请参阅无换行文本窗格。
Edit:
编辑：
Well, if you want to toggle the behaviour, then you would also need to toggle the getScrollableTracksViewportWidth() value. See Scrollable Panel. You should be able to toggle between FIT and STRETCH.
好吧，如果您想切换行为，那么您还需要切换 getScrollableTracksViewportWidth() 值。请参阅可滚动面板。您应该能够在 FIT 和 STRETCH 之间切换。
