I'm trying to build a GUI window in my application. What I'm trying to do is have a window, with a few buttons at the top, and a large text area. Something like this:
+--------------------------------------------------+
| [button1] [button2] [button3] |
| +----------------------------------------------+ |
| | text area | |
| | | |
| | | |
| | | |
| +----------------------------------------------+ |
+--------------------------------------------------+
I'm almost there, using GroupLayout:
layout.setHorizontalGroup(
layout.createParallelGroup()
.addGroup(layout.createSequentialGroup()
.addComponent(button1)
.addComponent(button2))
.addComponent(closeWindow))
.addComponent(textarea1)
);
layout.setVerticalGroup(
layout.createSequentialGroup()
.addGroup(layout.createParallelGroup()
.addComponent(button1)
.addComponent(button2)
.addComponent(button3))
.addComponent(textarea)
);
The problem is that this ends up with button3 aligned to the left, with the other two. I can't seem to figure out how I can specify the alignment on just that one button. I can do GroupLayout.Alignment.TRAILING on the entire button bar, but that hits all 3 buttons, which is also not quite right.
So what's the correct approach? Since the alignment only applies for Parallel Groups, I don't think having a HorizontalGroup with two Sequential Groups in it will help?
What am I missing?
