Scrollbar - need help

Posted: Apr 20, 2002 7:23 AM

Am trying to create a Panel with a Scrollbar. I have the scrollbars positioned horizontally and vertically but I can't seem to come up with a method to get the page to scroll down/across when I use it.
Can someone help pls?
Thanks

Instead of adding scroll bars to panel and implementing listeners to those scroll bars, you could save much time by adding your panel to JScrollPane as they have JScrollBars and JViewPort within.

JScrollPane scrollPane = new JScrollPane(thePanel);

This is a helpful tut-http://java.sun.com/docs/books/tutorial/uiswing/components/scrollpane.html

You might also try setting the size of your Panel with either the:
setSize(Dimension d);
or

setSize(int width, int height);
methods.
If you panel is a JPanel or if using a JScrollPane, use

setPreferredSize(Dimension d);

or
setPreferredSize(new Dimension (int width, int height));

etc..

Re:setting the Cursor to a new TextField

Posted: Apr 21, 2002 1:03 AM

Thanks for the help. Managed to do it! The scrollpane worked.

Would anyone know how to set the cursor to a TextField? For example I have 10 TextFields, all asking for input. For usability purposes, I would like the user to be able to enter their input, press "Enter" and follow on to the next TextField. At the moment I have to use tab to move to the next TextField.
I tried using t1.setCursor() (where t1 is my TextField) but I get the compilor error message:
setCursor() not found in java.awt.TextField

does anybody know what I should do?
Thanks
