[jaxx-interest] new blog entry: "Reinventing GridBagLayout"

[Anderson, Kelly]

>From your blog on Table...

<Table>
  <row>
    <cell><JLabel text='Username:'/></cell>
    <cell><JTextField id='username'/></cell>
  </row>
  
  <row>
    <cell><JLabel text='Password:'/></cell>
    <cell><JPasswordField id='password'/></cell>
  </row>

  <row>
    <cell columns='2'>
      <JPanel layout='{new GridLayout(1, 2, 6, 6)}'>
        <JButton text='OK'/>
        <JButton text='Cancel'/>
      </JPanel>
    </cell>
  </row>
</Table>

I don't know much about your Table XML, or GridBagLayout for that matter
but I wonder why you wouldn't just do something like this to layout that
dialog:

<Table>
	<column layout='Center'>
		<row layout='Center'> // meaning centered up and down.
			<JLabel text='Username:'/>
    			<JTextField id='username'/>
		</row>
  
		<row layout='Center'>
		    <JLabel text='Password:'/>
		    <JPasswordField id='password'/>
		</row>

		<row layout='Center'>
      		<JButton text='OK'/>
        		<JButton text='Cancel'/>
		</row>
	</column>
</Table>

Isn't that conceptually simpler? This uses the boxes and glue method
Donald Knuth pioneered in TeX for layout of mathematical formulas. I've
used it for dialog layout before, and it works very well (especially
once you add a 2D grid). I'm not certain of the reason for the <cell>
tag, but you could add it back in to such a scheme if you need it.

It also seems just to be good luck that the text boxes ended up being
the same width, how does that work?
