Get Reference of JScrollPane from JPanel

[Himanshu sGarg]

I have added a JScrollPane and added a JPanel to JscrollPane. How can I get reference to Jscrollpane from the JPanel in order to access properties of Jscrollpane?

[Maneesh Godbole]

This is kind of odd. What properties are you trying to access? What problem are you trying to solve?

[Himanshu sGarg]

I want that the buttons added to Jpanel inside jscrollpane should move while I scroll the Jscrollpane, i.e. the buttons in jpanel should always be visible while I scroll the scrollpane.

This can be done in (minimum) two ways
1) Create a panel with BorderLayout
2) Add scrollable content to the scroll pane
3) Add scroll pane to center of panel in #1 above
4) Add buttons to North, South, East, West of panel #1 above as per design.
This way, even if the content scrolls, your buttons dont.

The other way would be to pass to declare the scroll pane as an instance variable. Can you show us your panel code which has the scroll pane added to it?

5) Set a columnHeaderView
6) Set a rowHeaderView

Himanshu, I suspect that you are mucking around with a null layout and setBounds(...). Don't. Use a proper layout manager or a combination of them.

Oh wow! I agree Darryl has the better solution. I had completely forgotten about the column header

[Darryl Burke]

Not necessarily a better solution, and may not be acceptable of both the H- and V-scrollbars are active. The column header scrolls horizontally, and the row header scrolls vertically to sync with the viewportView.
