jscrollpane

I'd like to know if there is a way to know when a JScrollBar (vertical in my case) has reached the bottom of his containing JScrollPane . At first i have though of using an AdjustmentListener on the scroll bar but i don't know how to interpret the value attribute of the JScrollBar . Also i'm not sure to properly understand what the maximum represents and if i can use with the value to get the information i need. Edit : scrollPane.getVerticalScrollBar().addAdjustmentListener(new AdjustmentListener() { @Override public void adjustmentValueChanged(AdjustmentEvent ae) { System.out.println("Value:

I saw a few questions like this question, but I couldn't get this solved. I cannot get a JScrollPane visible on JTextArea . Can anyone please point out where I have done my mistake? Thanks. package experiement; import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTextArea; public class Experiment extends JFrame{ public Experiment(){ JTextArea tarea=new JTextArea(); tarea.setBounds(100,100,200,200); JScrollPane pan= new JScrollPane(); pan.setPreferredSize(new Dimension(100,100)); pan=new JScrollPane(tarea,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS

I have the following requirements: I need a scrollable JTextPane. The user may type into this text pane, or text may be inserted into it that is not typed by the user. Think something like an IM window. Although the window must be scrollable to allow the user to review text previously typed, the caret should never move from its position at the end of the text.

However, when the user presses the up and down arrow keys, the

I need to let users add more text fields to my JFrame so once the size of the frame has exceeded its original value a scroll pane would step in. Since I cannot add JScrollPane to JFrame in order to enable scrolling I decided to put the JPanel on the JFrame and pass the JPanel object into the JScrollPane constructor. Scrolling now works fine but only until it has reached the borders of the JPanel. The thing is the size of JPanel stays as is and is not stretching dynamically. What happens is the buttons in my code are using up all the space of the JPanel being the size of 300x300 but what I want

I have a JScrollPane , which has a JPanel for its content pane. To that JPanel I add smaller JPanel s, and as expected, if I add too much JPanel , a vertical scrollbar will appear. The problem is, that my small JPanel s contains a JScrollPane too for a JEditorPane . I'd like to use the mouse wheel only for the outer scrollpane, not for the smaller scrollpane. I already set wheelScrollingEnabled() to false for the small scrollpane, but if I scroll in any direction, and the mouse gets over the JEditorPane , the scrolling doesn't work anymore. Any advice? You may try to forward the wheel events
