java - MigLayout JTextArea is not shrinking when used with linewrap=true

Question

If I use a JTextArea with MigLayout like this:

MigLayout thisLayout = new MigLayout("", "[][grow]", "[]20[]");
   this.setLayout(thisLayout);
   {
jLabel1 = new JLabel();
this.add(jLabel1, "cell 0 0");
jLabel1.setText("jLabel1");
  }
  {
 jTextArea1 = new JTextArea();
this.add(jTextArea1, "cell 0 1 2 1,growx");
jTextArea1.setText("jTextArea1");
jTextArea1.setLineWrap(false);
   } 

then the JTextArea grows and shrinks perfectly when resizing the window. When I set the linewrap to true the JTextArea is not shrinking when I make the window smaller again. I would very much appreciate any help. Thanks

Answer 1

I just discovered that this can simply be resolved by changing the line

this.add(jTextArea1, "cell 0 1 2 1,growx");

to

this.add(jTextArea1, "cell 0 1 2 1,growx, wmin 10");

and no extra panels are needed. Setting an explicit minimum size is what does the trick.

Explanation: see the note under the section on padding in the MiGLayout whitepaper:
