iPadx

Hi,

I quite like the iPad functionality in GridBagLayout as it means I can for example, set a JComboBox so that its minimum size will always be big enough to display all the text and not have "..."
I'm using a different layout manager and I want this iPad functionality. I guess I can get it by specifying a fixed minimum size, but then I have to specify a fixed Dimension - with iPadx I could just do iPadx = 10; and not have to worry about the component height, so if I'm never fixing any components height then it is just using the swing defaults which is what I want.

Badly worded question, but basically how do I have iPadx functionality using a different layout manager other than GridBagLayout??

Cheers,
Cathal.

I think that if you put the JComboBox in a simple FlowLayout you'll automatically have this behaviour.

perhaps, but if i want it to be a little bit bigger again eg, 5 or 10 pixels bigger (so that it doesnt appear squashed - a little bit of breathing room!)

That's something I solve by setting my own ListCellRenderer which has

this.setBorder(new EmptyBorder(0,5,0,5)); // top, left, bottom, right

in it's constructor.

i added this code but it doesnt seem to have had any effect ??

opCombo.setRenderer(new DefaultListCellRenderer());
((DefaultListCellRenderer)opCombo.getRenderer()).setBorder(new EmptyBorder(0,20,0,20));

I've re-read your question:

Try this in the above code:

public ComboDemo() {
initComponents();

DefaultComboBoxModel model = new DefaultComboBoxModel();
model.addElement("Element one");
model.addElement("Element two");
model.addElement("Element eleven");
model.addElement("This is a rather long one");
theComboBox.setModel(model);

Dimension d = theComboBox.getPreferredSize();
d.setSize( 250, d.getHeight() );
theComboBox.setMinimumSize(d);
theComboBox.setPreferredSize(d);
}

thankyou,
they both work - i quite like the renderer solution, i just modified the constructor a little.

Thanks :)
