Prevent JLabels from Growing in MigLayout

Question

I am trying to create a form in MigLayout. I want for any text fields to be labeled with a small JLabel preceding it, with the text field growing as space is available. I am successfully able to do this in the following code: ``` JFrame frame = new JFrame("Test"); JPanel panel = new JPanel(new MigLayout("", "fill", "")); panel.add(new JLabel("Testing")); panel.add(new JTextField(), "growx, pushx, wrap"); frame.setContentPane(panel); frame.pack(); frame.setMinimumSize(new Dimension(400, 100)); frame.setPreferredSize(new Dimension(400, 100)); frame.setVisible(true); ``` The result looks like this, which is as expected (the JLabel is the minimum necessary size, the JTextField takes up the rest of the area): However, if I put a JEditorPane below this and have it span the length of the whole window, the JLabel becomes larger and grows if I enlarge the window. The code change looks like this: ``` ... panel.add(new JTextField(), "growx, pushx, wrap"); //New line of code here: panel.add(new J…

Accepted Answer

I figured it out! The problem is with the parameter on the JEditorPane:

```
panel.add(new JEditorPane(), "growx, pushx, span");
```

It turns out that when using `span`, `growx, pushx` is unnecessary (because it already grows in size) and when used in conjunction with this, it creates the effect shown above. My guess is that `growx` applies to all cells marked by `span`, but `pushx` only applies to the first cell.

So `span` makes the component take up multiple cells, they all were assigned the default `growx` weight, but `pushx` only makes the first cell grow.

So the proper way to fix the line is simply:

```
panel.add(new JEditorPane(), "span");
```
