TextField size and vertical align

Question

I use MigLayout on a `DialogBox`. Every panel uses MigLayout. There is a panel for the show row. There is a panel for every column (delivery type, choose element, Sortie). There is a panel for the output file row. There is a panel for button. Maybe there is a better way to do it wihout too much panels? My code ``` //set global layout this.setLayout( new MigLayout( "wrap 3, debug" ) ); this.add( getSearchPanel(), "span 3, wrap" ); // middle section this.add( getLivraison(), "width 33%" ); this.add( getChoixElement(), "width 33%" ); this.add( getProfile(), "width 33%" ); JLabel lblFichierSortie = new JLabel( "Output file" ); JTextField txtFichierSortie = new JTextField(); this.add( lblFichierSortie, "span 2, right" ); this.add( txtFichierSortie, "width 33%, wrap" ); this.add( getButton(), "span 3, right" ); private JPanel getSearchPanel() { JPanel searchPanel = new JPanel( new MigLayout() ); JLabel lblEmission = new JLabel( "Show" ); JTextField txtEmission = new JTextField( 10 ); JTextF…

Accepted Answer

Try this for the "top alignment problem" :

```
// set global layout
this.setLayout(new MigLayout("wrap 3, debug", null, "[top]"));
```

and for "the texfield size problem" :

```
this.add(getSearchPanel(), "span 3, wrap, grow");
```

If you want to have the same result without an inner JPanel, you can do :

```
final JLabel lblEmission = new JLabel("Show");
final JTextField txtEmission = new JTextField(10);
final JTextField txtEM = new JTextField(5);

this.add(lblEmission, "width 2%, span 3, split 3");
this.add(txtEmission, "right,width 60%, growx");
this.add(txtEM, "width 38%, growx");
```

However, this is not my favorite solution. With an inner panel the code is much more simple and reusable. I think when you will add some listeners for user interaction on the component s and controllers for the interactions with the model, this code will be over-complicated. When this will occurs, you may want to extract the `SearchPanel` into a reusable top-level class with a single responsability. Without a simple inner panel, it will be much more difficult to extract this class.

This is why when i design swing gui, i prefer to use first the BorderLayout and then the MigLayout (for more complex panel).
