I'm working on my very first GUI app.
I have an ArrayList of the Parent Class Plant of which I have four child classes.
I have some JTextFields with some information and some JCheckBoxs with other information...
The JTextFields should be converted into Strings and the JCheckBoxs into boolean.
I need to add all of these components to an ArrayList and then display the list of the Plants.
How can I do that?
Example:
public class Flower extends Plant{
private boolean thorns;
private boolean smell;
public Flower(String name, String id, String color, boolean blnThorns, boolean blnSmell){
super(name, id, color);
thorns = blnThorns;
smell = blnSmell;
}
public boolean isThorns(){
return thorns;
}
public void setThorns(boolean blnThorns){
thorns = blnThorns;
}
public boolean isSmell(){
return smell;
}
public void setSmell(boolean blnSmell){
smell = blnSmell;
}
}
This is my ArrayList
ArrayList<Plant> plantList = new ArrayList<Plant>();
Here I try to add the parameters for the Flower:
private void addFlower(ArrayList<Plant> plantList){
//Adding window
JFrame addingFrame = new JFrame();
addingFrame.setTitle("Plant Database Interface");
addingFrame.setSize(600, 200);
addingFrame.setLocationRelativeTo(null);
addingFrame.setVisible(true);
//ADDING FRAME LAYOUT
addingFrame.setLayout(new BorderLayout());
//TRAITS
JPanel fields = new JPanel();
addingFrame.add(fields, BorderLayout.NORTH);
JLabel nameLabel = new JLabel("Name:");
JTextField nameField = new JTextField(15);
String name = nameField.getText();
JLabel idLabel = new JLabel("ID:");
JTextField idField = new JTextField(10);
String id = idField.getText();
JLabel colorLabel = new JLabel("Color:");
JTextField colorField = new JTextField(10);
String color = colorField.getText();
fields.add(nameLabel);
fields.add(nameField);
fields.add(idLabel);
fields.add(idField);
fields.add(colorLabel);
fields.add(colorField);
JPanel traits = new JPanel();
addingFrame.add(traits , BorderLayout.CENTER );
JCheckBox thornsBox = new JCheckBox("Thorns Present");
thornsBox.setSelected(false);
traits.add(thornsBox);
JCheckBox smellBox = new JCheckBox("Smell Present");
smellBox.setSelected(false);
traits.add(smellBox);
JPanel southPanel = new JPanel();
addingFrame.add(southPanel, BorderLayout.SOUTH);
JButton addPlantBtn = new JButton("Add Plant");
southPanel.add(addPlantBtn, BorderLayout.EAST);
JButton cancelBtn = new JButton("Cancel");
southPanel.add(cancelBtn, BorderLayout.WEST);
boolean blnThorns;
boolean blnSmell;
//I REALLY DON'T KNOW HOW TO DO THIS PART
thornsBox.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e){
if(e.getStateChange() == ItemEvent.SELECTED){
blnThorns =true;
}
else{
blnThorns = false;
}
}
});
smellBox.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e){
if(e.getStateChange() == ItemEvent.SELECTED){
blnSmell =true;
}
else{
blnSmell = false;
}
}
});
addPlantBtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//plantList.add(new Flower(name, id, color, blnThorns, blnSmell)); //HOW TO DO????................
}
});
cancelBtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
addingFrame.dispatchEvent(new WindowEvent(addingFrame, WindowEvent.WINDOW_CLOSING));
}
});
}
Use your addPlantBtn ActionListener to gather the information you need when it's called
addPlantBtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Flower flower = new Flower(nameField.getText(), idField.getText(), colorField.getText(), thornsBox.isSelected(), smellBox.isSelected());
plantList.add(flower);
You would, also, find it easier, if you created a dedicated JPanel, designed to gather the user details and generate a Flower when you requested it to (from the values of the fields). You could then use this panel on some kind of dialog when ever you needed it.
Have a look at How to Make Dialogs for more details
For example...
public class FlowerPane extends JPanel {
JTextField nameField = new JTextField(15);
JTextField idField = new JTextField(10);
JTextField colorField = new JTextField(10);
JCheckBox smellBox = new JCheckBox("Smell Present");
JCheckBox thornsBox = new JCheckBox("Thorns Present");
public FlowerPane() {
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(2, 2, 2, 2);
JLabel nameLabel = new JLabel("Name:");
JLabel idLabel = new JLabel("ID:");
JLabel colorLabel = new JLabel("Color:");
add(nameLabel, gbc);
gbc.gridy++;
add(idLabel, gbc);
gbc.gridy++;
add(idLabel, gbc);
gbc.gridx++;
gbc.gridy = 0;
add(nameField, gbc);
gbc.gridy++;
add(idField, gbc);
gbc.gridy++;
add(colorField, gbc);
gbc.gridx = 0;
gbc.gridwidth = GridBagConstraints.REMAINDER;
add(thornsBox, gbc);
gbc.gridy++;
add(smellBox, gbc);
}
public Flower create() {
return new Flower(nameField.getText(), idField.getText(), colorField.getText(), thornsBox.isSelected(), smellBox.isSelected());
}
}
Which you could then use by doing something like...
FlowerPane flowerPane = new FlowerPane();
switch (JOptionPane.showConfirmDialog(null, flowerPane, "Flower", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE)) {
case JOptionPane.OK_OPTION:
Flower flower = flowerPane.create();
plantList.add(flower);
break;
}
Or add it to some other container
