Hi guys
I'm having a little problem here. I've designed a bean with a Scrollpane and a panel inside it. Labels and Textfields are added to the panel continuosly, and I've currently set the Panel's layout to null. In one of the cases for the TextFields, I've added a mouseclicked event wherein a calendar pops up inside the bean when the user clicks inside the TextField which has the date. Now, the problem is that initially, the panel's layout was Gridlayout, but when I do the same, all the components get sized to that of a calendar and it looks bad and now that the layout is null, the scrollbar's not appearing. If I happen to size the calendar small , then the user will not be able to select the date. Please help me with this.
Thanks
Meghna

Hi Cindy
Thanks for the reply, but setting the Panel's layout to FlowLayout is aligning all the components horizontally. Basically, the look need is Labels on the Left side and TextFields on the right side of the panel. GridLayout was working perfectly until the Calendar came into existence. So,
Please let me know if you come up with some idea.
Thanks in advance
Meghna

I think you will have to use a gridBag layout to get the results you need. Check out Professional Java Programming (WROX) for a great discussion of the gridBag. In your case, if you just have 2 columns of data, you will want to set your constraints' gridwidth setting to 1 for the right column and constraints.gridwidth to REMAINDER before adding each left column object:
panel.setLayout(new GridBagLayout());
GridbagConstraints bag = new GridBagConstraints();
bag.gridwidth = 1;
panel.add(component1, bag);
bag.gridwidth = GridBagConstraints.REMAINDER;
panel.add(component2, bag);
etc, etc.

Not looking good. I think this might be the end. Wait! Is that a tiny ad?
