Java – arrange swing components by edge
•
Java
Can swing components be arranged?
You can see a subtle difference that I find very annoying I know that all jlabels [Blue / Purple rectangles have the same size, so I think it may be because of "and" * ", but I'm not sure because the left boxes of the first two don't line up
panel
JPanel panel2 = new JPanel(new GridLayout(4,1)); JPanel panel2a = new JPanel(new FlowLayout()); JPanel panel2b = new JPanel(new FlowLayout());
First two rectangles (purple)
add1 = new JLabel("",JLabel.CENTER); add1.setTransferHandler(new TransferHandler("text")); add1.setBorder(b2); add2 = new JLabel("",JLabel.CENTER); add2.setTransferHandler(new TransferHandler("text")); add2.setBorder(b2);
Two blue rectangles
textFieldA = new JTextField(); textFieldA.setHorizontalAlignment(JTextField.CENTER); textFieldA.setEditable(false); textFieldA.setBorder(new LineBorder(Color.blue)); textFieldM = new JTextField(); textFieldM.setHorizontalAlignment(JTextField.CENTER); textFieldM.setEditable(false); textFieldM.setBorder(new LineBorder(Color.blue));
And*
opA = new JLabel("+",JLabel.CENTER); opS = new JLabel("*",JLabel.CENTER);
The display rectangle is the same size
Dimension d = card1.getPreferredSize(); int width = d.width + 100; int height = d.height + 50; add1.setPreferredSize(new Dimension(width,height)); add2.setPreferredSize(new Dimension(width,height)); mult1.setPreferredSize(new Dimension(width,height)); mult2.setPreferredSize(new Dimension(width,height)); textFieldA.setPreferredSize(new Dimension(width,height)); textFieldM.setPreferredSize(new Dimension(width,height));
Add to panel
panel2a.add(add1); panel2a.add(opA); panel2a.add(add2); panel2a.add(enterA); panel2a.add(textFieldA); panel2c.add(mult1); panel2c.add(opM); panel2c.add(mult2); panel2c.add(enterM); panel2c.add(textFieldM); panel2.add(panel2a); panel2.add(panel2c);
Solution
Afaiu can be implemented using grouplayout This layout requires five horizontal groups and two vertical groups
For an example, see how to use grouplayout, including a discussion of the image
