问题 I am working on a project for my college course. I was just wondering if anyone knew how to add a scrollBar to a JTextArea. At present I have the GUI laid out correctly, the only thing missing is the scroll bar. This is what the GUI looks like. As you can see on the second TextArea I would like to add the Scrollbar. This is my code where I create the pane. But nothing seems to happen... t2 is the JTextArea I want to add it to. scroll = new JScrollPane(t2); scroll.setBounds(10,60,780,500);

JTable with horizontal scrollbar

由 爱⌒轻易说出口 提交于 2019-11-26 16:32:20
Is there any way to enable horizontal scroll-bar whenever necessary? The situation was as such: I've a JTable , one of the cells, stored a long length of data. Hence, I need to have horizontal scroll-bar. Anyone has idea on this?
