I have a simple problem which totally drives me crazy.
I have a JList, and would like its cells to expand depending on their content, which is text of variable length.
So I created a CustomCellRenderer like so:
@Override
public Component getListCellRendererComponent(final JList list, final Object value, final int index, final boolean isSelected, final boolean hasFocus)
{
final String text = (String) value;
final JTextArea ta = new JTextArea();
ta.setText(text);
ta.setFont(new Font("Dialog", Font.PLAIN, (int) Theme.FONTSIZE_TEXT));
ta.setForeground(Theme.FONTCOLOR_CONTENT);
ta.setLineWrap(true);
ta.setWrapStyleWord(true);
ta.setColumns(0);
ta.setBorder(BorderFactory.createEmptyBorder(10, Theme.PADDING, 0, 0));
return ta;
}
but the cells are only one text line high and the rest of the JTextArea is cut off. If I add
ta.setPreferredSize(new Dimension(0, 70));
I get a row height of 70 and I can see more of the JTextArea's text, but still not everything.
Is there any way to make JList expand its cells so that the whole content of the JTextArea is displayed?
there are maybe easiest and nicest way, I think that JTable with one TableColumn (and without TableHeader)in all cases better as JList, here is your Render MacOX version
then output should be
Not sure if there is an elegant way. One way that I know works is as follows : In
getListCellRendererComponent()
<br>
in to the text where desired.Try using JList's setFixedCellHeight() method.
