Preventing JList from auto resizing

java, jlist, preferredsize, swing, user-interface

Solution

Depending on what it is you trying archive, you can either use `JList#setPrototypeCellValue` or `JList#setFixedCellWidth`. These will feed back into the PeferredScrollableViewportSize method which will effect the scroll pane

Problem

I have a JList inside a JScrollPane that's placed in a JPanel (BorderLayout.CENTER) and putting that inside another JPanel's BorderLayout.EAST (this JPanel's CENTER contains another JPanel) and this whole JPanel is placed inside a JTabbedPane. Initially, it would look like this: Now I add some books to the list: If I go to another tab and come back, this happens: What I don't understand is that, the JPanel containing the JList has both its minimum and maximum size set: ``` JPanel listPanel = new JPanel(); listPanel.setLayout(new BorderLayout()); listPanel.add(new JScrollPane(bookList), BorderLayout.CENTER); listPanel.setMinimumSize(listPanel.getPreferredSize()); listPanel.setMaximumSize(listPanel.getPreferredSize()); checkOutPanel.add(listPanel, BorderLayout.EAST); ``` How can I prevent the JList from auto resizing?
