If you don't care about the layout manager, but only care about the layout, then you should use a GridLayout
, or if you don't want all component to be the same size, a GridBagLayout
. Here's how with a grid layout (only the modified method is shown):
public JPanel createPanel() {
JPanel panel = new JPanel();
panel.setLayout(new GridLayout());
okButton = new JButton("Ok");
cancellButton = new JButton("Cancel");
idTF = new JTextField(10);
nameTf = new JTextField(10);
idlbl = new JLabel("ID");
namelbl = new JLabel("Name");
panel.add(idlbl);
panel.add(idTF);
panel.add(namelbl);
panel.add(nameTf);
panel.add(okButton);
panel.add(cancellButton);
return panel;
}
And with a GridBagLayout
:
public JPanel createPanel() {
JPanel panel = new JPanel();
GridBagLayout gb = new GridBagLayout();
GridBagConstraints gbc = new GridBagConstraints();
panel.setLayout(gb);
okButton = new JButton("Ok");
cancellButton = new JButton("Cancel");
idTF = new JTextField(10);
nameTf = new JTextField(10);
idlbl = new JLabel("ID");
namelbl = new JLabel("Name");
add(panel, idlbl, 0, 0, 1, 1, gb, gbc, false);
add(panel, idTF, 0, 1, 1, 1, gb, gbc, true);
add(panel, namelbl, 1, 0, 1, 1, gb, gbc, false);
add(panel, nameTf, 1, 1, 1, 1, gb, gbc, true);
add(panel, okButton, 2, 0, 1, 1, gb, gbc, false);
add(panel, cancellButton, 2, 1, 1, 1, gb, gbc, true);
return panel;
}
private void add(Container outer, Component c, int x, int y, int w, int h, GridBagLayout gb, GridBagConstraints gbc, boolean wide) {
gbc.gridx = x;
gbc.gridy = y;
gbc.gridwidth = w;
gbc.gridheight = h;
if (wide) {
gbc.weightx = 100;
} else {
gbc.weightx = 0;
}
gb.setConstraints(c, gbc);
outer.add(c);
}
I believe that the extra GridBagLayout
complexity just might be worth it.
