I am trying to create a simple menu interface with 4 rows of various buttons and labels using GridLayout
with FlowLayout
inside each grid for organising the elements. However the space for the buttons and labels which should only take 1 line takes up a huge amount of space.
This is what my interface looks like minimized:
This is what it looks like maximized:
I am looking to set the maximum size of the labels panels/grid so that it only takes a small amount of space.
I am trying to make all the elements visible without anything being hidden with as small a window size as possible like this:
This is my code:
public class Window extends JFrame{
public Window() {
super("TastyThai Menu Ordering");
}
public static void main(String[] args) {
Window w = new Window();
w.setSize(500, 500);
w.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel title = new JLabel("TastyThai Menu Order", SwingConstants.CENTER);
title.setFont(title.getFont().deriveFont(32f));
//generate page title
Container titlePanel = new JPanel(); // used as a container
titlePanel.setBackground(Color.WHITE);
FlowLayout flow = new FlowLayout(); // Create a layout manager
titlePanel.setLayout(flow);// assign flow layout to panel
titlePanel.add(title); // add label to panel
w.getContentPane().add(BorderLayout.NORTH,titlePanel);
//generate row containers
Container r1 = new JPanel(new FlowLayout());
Container r2 = new JPanel(new FlowLayout());
Container r3 = new JPanel(new FlowLayout());
Container r4 = new JPanel(new FlowLayout());
//generate mains radio buttons
Container mains = new JPanel(new GridLayout(7, 0));
mains.setBackground(Color.RED);
JLabel mainsHeader = new JLabel("Mains");
mains.add(mainsHeader);
String[] mainsChoices = {"Vegetarian", "Chicken", "Beef", "Pork", "Duck", "Seafood Mix"};
JRadioButton[] mainsRadioButton = new JRadioButton[6];
ButtonGroup mainsButtons = new ButtonGroup();
for(int i = 0; i < mainsChoices.length; i++) {
mainsRadioButton[i] = new JRadioButton(mainsChoices[i]);
mains.add(mainsRadioButton[i]);
mainsButtons.add(mainsRadioButton[i]);
}
//generate noodles radio buttons
Container noodles = new JPanel(new GridLayout(7, 0));
noodles.setBackground(Color.GREEN);
JLabel noodlesHeader = new JLabel("Noodles");
noodlesHeader.setFont(noodlesHeader.getFont().deriveFont(24f));
noodles.add(noodlesHeader);
String[] noodlesChoices = {"Pad Thai", "Pad Siew", "Ba Mee"};
JRadioButton[] noodlesRadioButton = new JRadioButton[3];
ButtonGroup noodlesButtons = new ButtonGroup();
for(int i = 0; i < noodlesChoices.length; i++) {
noodlesRadioButton[i] = new JRadioButton(noodlesChoices[i]);
noodles.add(noodlesRadioButton[i]);
noodlesButtons.add(noodlesRadioButton[i]);
}
//generate sauces radio buttons
Container sauces = new JPanel(new GridLayout(7, 0));
sauces.setBackground(Color.BLUE);
JLabel saucesHeader = new JLabel("Sauce");
saucesHeader.setFont(saucesHeader.getFont().deriveFont(24f));
sauces.add(saucesHeader);
String[] saucesChoices = {"Soy Sauce", "Tamarind Sauce"};
JRadioButton[] saucesRadioButton = new JRadioButton[2];
ButtonGroup saucesButtons = new ButtonGroup();
for(int i = 0; i < saucesChoices.length; i++) {
saucesRadioButton[i] = new JRadioButton(saucesChoices[i]);
sauces.add(saucesRadioButton[i]);
saucesButtons.add(saucesRadioButton[i]);
}
//generate extras check boxes
Container extras = new JPanel(new GridLayout(7, 0));
extras.setBackground(Color.YELLOW);
JLabel extrasHeader = new JLabel("Extra");
extrasHeader.setFont(extrasHeader.getFont().deriveFont(24f));
extras.add(extrasHeader);
String[] extrasChoices = {"Mushroom", "Egg", "Broccoli", "Beansrpout", "Tofu"};
JCheckBox[] extrasBoxes = new JCheckBox[5];
for(int i = 0; i < extrasChoices.length; i++) {
extrasBoxes[i] = new JCheckBox(extrasChoices[i]);
extras.add(extrasBoxes[i]);
}
JLabel selectionPrice = new JLabel("Selection Price: $ ");
JLabel selectionPriceVal = new JLabel("_______________");
JButton addToOrder = new JButton("Add to Order");
JLabel totalPrice = new JLabel("Total Price: $ ");
JLabel totalPriceVal = new JLabel("_______________");
JButton clearOrder = new JButton("Clear Order");
JRadioButton pickUp = new JRadioButton("Pick Up");
JRadioButton delivery = new JRadioButton("Delivery");
ButtonGroup pickupDelivery = new ButtonGroup();
pickupDelivery.add(pickUp);
pickupDelivery.add(delivery);
JButton completeOrder = new JButton("Complete Order");
Container menuSelection = new JPanel(new GridLayout(4,0));
menuSelection.add(r1);
r1.add(mains);
r1.add(noodles);
r1.add(sauces);
r1.add(extras);
menuSelection.add(r2);
r2.add(selectionPrice);
r2.add(selectionPriceVal);
r2.add(addToOrder);
menuSelection.add(r3);
r3.add(totalPrice);
r3.add(totalPriceVal);
r3.add(clearOrder);
menuSelection.add(r4);
r4.add(pickUp);
r4.add(delivery);
r4.add(completeOrder);
w.getContentPane().add(BorderLayout.CENTER, menuSelection);
w.setVisible(true);
}
}
GridLayout does not support that. All rectangles have the same size.
Take a look at the GridBagLayout, which supports dynamic resizing and much more.
