Problem while scrolling a JScrollPane - Threads

Question

Hello,

The situation is like this:

Upon clicking on a menu item, some components are added to a JScrollPane, the components are resized, then setVisible method of JScrollPane is called. Resizing of components are out of my control. (TextAreas getting resized according to their contents. Caret updates are disabled.)

I want to scroll the JScrollPane to the bottom. Using invokeLater and a Runnable that scrolls the list down by using getMaximumValue method does not seem to work in this case (while it normally does for other parts of the program).

Is there a way to make the Runnable thread get notified after making sure that everything related to the operations above are done?

Thanks in advance.

Answer 1

Why are you doing that with another Thread? Could you instead use

JViewPort view = new JViewPort();
view.setPoint(new Point(0, heightOfContents));
scrollPane.setViewPort(view);

That, or something similar should do what you need.

Answer 2

You colud try to create new thread and call dummy invokeAndWait on that thread. After that, all pending events should be finished and your scroll code should work.
