问题
I have tried searching multiple time on how to format java swing elements multiple times, but I can't seem to find anything. I have tried to learn the grid bag layout but it is all too complicated. Could someone please tell me how to space swing components with Swing? Thanks!
EDIT
Code:
import javax.swing.*;
import java.awt.*;
public class Format_Swing_Elemnts {
public static void main(String[] args) {
JLabel title = new JLabel("Bridge Settings:");
title.setFont(font);
JLabel l1 = new JLabel("Number of Bars: ");
JLabel l2 = new JLabel("Deck Elevation: ");
JLabel l3 = new JLabel("Height of arch: ");
JLabel l4 = new JLabel("Height of Pier: ");
JLabel l5 = new JLabel("Cabel Anchorage: ");
JLabel l6 = new JLabel("Concrete Type: ");
final JLabel lM1 = new JLabel("meters");
final JLabel lM2 = new JLabel("meters");
final JLabel lM3 = new JLabel("meters");
final JRadioButton p1RB1 = new JRadioButton("Standard Abutments");
final JRadioButton p1RB2 = new JRadioButton("Arch Abutments");
final JRadioButton p2RB1 = new JRadioButton("No Pier (one span)");
final JRadioButton p2RB2 = new JRadioButton("Pier (two spans)");
final JRadioButton p3RB1 = new JRadioButton("No Cable Anchorage");
final JRadioButton p3RB2 = new JRadioButton("One Cable Anchorage");
final JRadioButton p3RB3 = new JRadioButton("Two Cable Anchorage");
final JRadioButton p4RB1 = new JRadioButton("Meduim Strength Concrete");
final JRadioButton p4RB2 = new JRadioButton("High Strength Concrete");
ButtonGroup p1 = new ButtonGroup();
p1.add(p1RB1);
p1.add(p1RB2);
ButtonGroup p2 = new ButtonGroup();
p2.add(p2RB1);
p2.add(p2RB2);
ButtonGroup p3 = new ButtonGroup();
p3.add(p3RB1);
p3.add(p3RB2);
p3.add(p3RB3);
ButtonGroup p4 = new ButtonGroup();
p4.add(p4RB1);
p4.add(p4RB2);
final SpinnerModel model = new SpinnerNumberModel(0, 0, 1000, 1);
final JSpinner numberBars = new JSpinner(model);
final JSpinner deckElevation = new JSpinner(new SpinnerNumberModel(24, 0, 24, 4));
final JSpinner archHeight = new JSpinner(new SpinnerNumberModel(4, 4, 24, 4));
final JSpinner pierHeight = new JSpinner(new SpinnerNumberModel(0, 0, 24, 4));
JFormattedTextField tf1 = ((JSpinner.DefaultEditor)deckElevation.getEditor()).getTextField();
tf1.setEditable(false);

tf2.setEditable(false);
JFormattedTextField tf3 = ((JSpinner.DefaultEditor)pierHeight.getEditor()).getTextField();
tf3.setEditable(false);
JButton quit = new JButton("Quit");
JButton continueB = new JButton("Continue");
JPanel format2 = new JPanel();
format2.add(title);
//New line
format2.add(l1);
format2.add(numberBars);
//New line
format2.add(l2);
format2.add(deckElevation);
format2.add(lM1);
//New line
format2.add(p1RB1);
format2.add(p1RB2);
format2.add(l3);
format2.add(archHeight);

//New line

format2.add(p3RB2);

//New line
format2.add(quit);
format2.add(continueB);
JFrame part2Window = new JFrame("Part 2 - Adjust your settings");
part2Window.add(format2);
part2Window.setSize(290, 365);
part2Window.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
part2Window.setVisible(true);

回答1:
I improvised a bit with that spacer label. I hope that some experienced users won't be mad ;). But I hope this is what you are looking for:
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JSpinner;
import javax.swing.SpinnerModel;
import javax.swing.SpinnerNumberModel;
import javax.swing.SwingUtilities;
import net.miginfocom.swing.MigLayout;
public class MyFormat extends JFrame {
JPanel panel = new JPanel();
JLabel spacer, bridgeSet, numOfBars, deckElev, meters, heightOfArch, heightOfPier,
cabelAnch, concreteType;
SpinnerModel model = new SpinnerNumberModel(0, 0, 1000, 1);
JSpinner numberBars = new JSpinner(model);
JSpinner deckElevation = new JSpinner(new SpinnerNumberModel(24, 0, 24, 4));
JSpinner archHeight = new JSpinner(new SpinnerNumberModel(4, 4, 24, 4));
JSpinner pierHeight = new JSpinner(new SpinnerNumberModel(0, 0, 24, 4));
JRadioButton standAbut = new JRadioButton("Standard Abutments");
JRadioButton archAbut = new JRadioButton("Arch Abutments");
JRadioButton noPier = new JRadioButton("No Pier (one span)");
JRadioButton pier = new JRadioButton("Pier (two spans)");
JRadioButton noCabAnch = new JRadioButton("No Cable Anchorage");
JRadioButton oneCabAnch = new JRadioButton("One Cable Anchorage");
JRadioButton twoCabAnch = new JRadioButton("Two Cable Anchorage");
JRadioButton medStrCon = new JRadioButton("Meduim Strength Concrete");
JRadioButton highStrCon = new JRadioButton("High Strength Concrete");
JButton continueBtn = new JButton("Continue");
JButton quitBtn = new JButton("Quit");
public MyFormat() {
super("Adjust your settings");
panel.setLayout(new MigLayout());
panel.add(bridgeSet = new JLabel("Bridge settings:"), "wrap");
panel.add(spacer = new JLabel(" "),"span, grow");
panel.add(numberBars, "span, grow");
panel.add(numOfBars = new JLabel("Number of bars:"));
panel.add(numberBars, "span, grow");
panel.add(deckElev = new JLabel("Deck elevation: "));
panel.add(deckElevation);
panel.add(meters = new JLabel("meters"), "wrap");
panel.add(spacer = new JLabel(" "),"span, grow");
panel.add(standAbut, "span, grow");
panel.add(archAbut, "span, grow");
panel.add(heightOfArch = new JLabel("Height of arch: "));
panel.add(archHeight);
panel.add(meters = new JLabel("meters"), "wrap");
panel.add(spacer = new JLabel(" "),"span, grow");
panel.add(noPier, "span, grow");
panel.add(pier, "span, grow");
panel.add(heightOfPier = new JLabel("Height of pier: "));
panel.add(pierHeight);
panel.add(meters = new JLabel("meters"), "wrap");
panel.add(spacer = new JLabel(" "),"span, grow");
panel.add(cabelAnch = new JLabel("Cable anchorage:"),"wrap");
panel.add(noCabAnch,"span, grow");
panel.add(oneCabAnch,"span, grow");
panel.add(twoCabAnch,"span, grow");
panel.add(spacer = new JLabel(" "),"span, grow");
panel.add(concreteType = new JLabel("Concrete type: "),"wrap");
panel.add(medStrCon,"span, grow");
panel.add(highStrCon,"span, grow");
panel.add(spacer = new JLabel(" "),"span, grow");
panel.add(continueBtn);
panel.add(quitBtn);
add(panel);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
MyFormat mf = new MyFormat();
mf.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
mf.pack();
mf.setLocationByPlatform(true);
mf.setVisible(true);
}
});
}
}
P.S. Used layout: MigLayout
回答2:
Have you tried it with a GUI editor like netbeans or WindowBuilderPro from google for eclipse? It's a lot easyer with an editor like this and also a good way to learn how the different layouts work out together. Hope this helps.
回答3:
I use a Box with vertical orientation when GridBag feels like overkill.
回答4:
I have also found an easier way using the Grid Layout that is much simpler than the Mig Layout. Sorry for the trouble!
