I want to have a scrollpane inside a panel while the scrollpane covers the whole panel. How can I do that?
Ensure the JPanel has a BorderLayout, then add the JScrollPane to the BorderLayout.CENTER constraint. Of course, don't add anything else to the NORTH/E/W/S constraints.

I have added some collapsible panels to my JScrollpane. When they are extended, the JScrollpane is not allowing me to scroll. Below is the code I'm using.
JScrollPane scrollPane = new JScrollPane(makeContentForPropertiesWindow());
propertiesTabDoc.add(scrollPane,BorderLayout.CENTER);
scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
The makeContentForPropertiesWindow method populates the collapsible panels. I've used GridLAyout there. I've also tried FlowLayout and BorderLAyout as well. All result in the same output. Currently below is how it looks.
What am I doing wrong here? Why is it not allowing me to scroll though the vertical area is full? Please advice.
I have added a scroll pane to the main panel of my frame. But it doesn't display properly, here's what I get that appears on the right:

here is the code:
JScrollPane jScrollPane = new JScrollPane(area);
jScrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
jScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
jScrollPane.setViewportBorder(new LineBorder(Color.RED));
pane.add(jScrollPane, BorderLayout.EAST);
EDIT: Forgot to mention that area is a label.
1) Use another proper LayoutManager, I'd suggesst use Box or directly BoxLayout
or
2) all areas excluding BorderLayout.CENTER acepted PreferredSize came from JComponent
3) if your area is JTextArea the you can pretty to set JTextArea(int rows, int columns)
I have a JTable with autoResizeMode set to AUTO_RESIZE_LAST_COLUMN. I have added it to a panel by creating a JScrollPane with the JTable as its child widget, and then adding the JScrollPane to the panel.
I would like to set the size of the JScrollPane viewport to that of the parent JPanel, and have the JTable resize its last column dynamically.
JPanel have got implemented FlowLayout by defaut, you can place JScrollPane to the BorderLayout.CENTER
I think if you make the JPanel use GridLayout(1,1) and add the JScrollPane to it then you will get the desired result.
The first answer on this link How to make a JTable fill entire available space? worked perfectly for me.
I did the following
myPanel = new JPanel(new GridLayout());
myJtable = new JTable(MyTableModel);
myPanel.add(new JScrollPane(myJtable));
I have a problem.
I have a JFrame with some JTextFields, JLabels, Jlists & JButtons now the contents of my frame is more than the screen area so I want to attach a JScrollBar to my JFrame but my srollbar does not work. So, can anyone please guide me on how I can scroll my JFrame using the JScrollbar?
Put all the components in one panel (instead of in the JFrame)
Add this panel to a JScrollPane
Add the JScrollPane to your frame.
I should be something like:
JPanel container = new JPanel();
container.add(panel1);
container.add(Panel2);
JScrollPane jsp = new JScrollPane(container);
frame.add(jsp);
It depends on the layout you are using with your JFrame. If you want to add working scrollbar to your panel you should look at the JScrollPane class and the Scrollable interface which must be implemented by scrollable components.

Add your panel to scrollpane and add that pane where you are adding your panel instead of panel
JScrollPane jScrollPane = new JScrollPane(panel);
