How to add buttons to every row in my for-loop - java

I wish to implement a button to every row in my for-loop. But i have no idea how to do it.
I would like to be able to edit data in each row by pressing a button.
for(HentbestillingsordreRegistrer hentboregistrer: hbor){
if(status.equals("Leveret")){
temp.append("<html>");
temp.append("BestillingsID: ");
temp.append(hentboregistrer.BestillingsID);
temp.append("<br />");
temp.append("Ordre Status:");
temp.append(hentboregistrer.BestillingsStatus);
temp.append("<br />");
temp.append("LeverandoerID: ");
temp.append(hentboregistrer.Leverandoernavn);
temp.append("<br />");
temp.append("Modtaget af: ");
temp.append(hentboregistrer.ModtagetAf);
temp.append("<br />");
temp.append("<br />");
}else{
temp.append("<html>");
temp.append("BestillingsID: ");
temp.append(hentboregistrer.BestillingsID);
temp.append("<br />");
temp.append(hentboregistrer.BestillingsStatus);
temp.append("<br />");
temp.append("LeverandoerID: ");
temp.append(hentboregistrer.Leverandoernavn);
temp.append("<br />");
temp.append("Modtaget af: ");
temp.append(hentboregistrer.ModtagetAf);
temp.append("<br />");
temp.append("<br />");
}
}
return temp.toString();
}
public JPanel HentOrdreGUI(){
JPanel info = new JPanel();
info.setLayout(new BorderLayout());
JLabel labelprintdata = new JLabel(temp.toString());
JScrollPane scroll = new JScrollPane(labelprintdata);
info.add(scroll, BorderLayout.CENTER);
return info;
}

I would change the JLabel into a JTable, and add a JButton as the 3rd column of the table. Something like this...
// Create a container for all your table data.
// There are 3 columns (type, value, button) in the table.
// And each order has 4 items in it (BestillingsId, Status, LeverandoerID, Modtaget)
Object[][] tableData = new Object[numOrders*4][3];
for(int i=0;i<numOrders;i++){
HentbestillingsordreRegistrer hentboregistrer = hbor[i];
// For each order, we need to add 4 rows, each with 3 cells in it (to hold the type, value, and the button)
if(status.equals("Leveret")){
tableData[(i*4)+0] = new Object[]{"BestillingsID",hentboregistrer.BestillingsID,new JButton("Edit")};
tableData[(i*4)+1] = new Object[]{"Ordre Status",hentboregistrer.BestillingsStatus,new JButton("Edit")};
tableData[(i*4)+2] = new Object[]{"LeverandoerID",hentboregistrer.Leverandoernavn,new JButton("Edit")};
tableData[(i*4)+3] = new Object[]{"Modtaget af:",hentboregistrer.ModtagetAf,new JButton("Edit")};
}
else{
tableData[(i*4)+0] = new Object[]{"BestillingsID",hentboregistrer.BestillingsID,new JButton("Edit")};
tableData[(i*4)+1] = new Object[]{"Ordre Status",hentboregistrer.BestillingsStatus,new JButton("Edit")};
tableData[(i*4)+2] = new Object[]{"LeverandoerID",hentboregistrer.Leverandoernavn,new JButton("Edit")};
tableData[(i*4)+3] = new Object[]{"Modtaget af:",hentboregistrer.ModtagetAf,new JButton("Edit")};
}
}
// Headings for the table columns
String[] tableHeadings = new String[]{"Type","Value","Button"};
JPanel info = new JPanel();
info.setLayout(new BorderLayout());
// Create the table from the data above
JTable table = new JTable(tableData,tableHeadings);
JScrollPane scroll = new JScrollPane(table);
info.add(scroll, BorderLayout.CENTER);

Is it possible to change the height of each grid in a GridLayout?

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"};

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"};

extras.add(extrasHeader);
String[] extrasChoices = {"Mushroom", "Egg", "Broccoli", "Beansrpout", "Tofu"};
JCheckBox[] extrasBoxes = new JCheckBox[5];
for(int i = 0; i < extrasChoices.length; i++) {

GridLayout does not support that. All rectangles have the same size.
Take a look at the GridBagLayout, which supports dynamic resizing and much more.

Split labels in JTabbedPane

I need to change my label's distribution on a JTabbedPane.
I have this:
And I want to do this:
Can someone help me?
I post the code below:
tabbedResultsPane = new JTabbedPane(SwingConstants.TOP);
JPanel featurePanel = new JPanel(new GridLayout(TOTAL_FEATURES, 2, 3, 3));
estadoScroll = new JScrollPane(featurePanel,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
lblFeatureHdr = new JLabel[TOTAL_FEATURES];
lblFeature = new JLabel[TOTAL_FEATURES];
for(int i=0; i<TOTAL_FEATURES; i++)
{
lblFeatureHdr[i] = new JLabel(strHeader[i], JLabel.RIGHT);
lblFeatureHdr[i].setOpaque(true);
lblFeatureHdr[i].setBackground(new Color(220,255,220));//.lightGray);
lblFeature[i] = new JLabel("", JLabel.LEFT);
lblFeature[i].setForeground(Color.blue);// black);
featurePanel.add(lblFeatureHdr[i]);
featurePanel.add(lblFeature[i]);
}
Define 4 columns GridLayout (rather than 2 columns you have).
and correct your code yo add 2 more labels for each row.
for(int i=0; i<TOTAL_FEATURES; i++)
{
lblFeatureHdr[i] = new JLabel(strHeader[i], JLabel.RIGHT);
lblFeatureHdr[i].setOpaque(true);
lblFeatureHdr[i].setBackground(new Color(220,255,220));//.lightGray);
lblFeature[i] = new JLabel("", JLabel.LEFT);
lblFeature[i].setForeground(Color.blue);// black);
featurePanel.add(lblFeatureHdr[i]);
featurePanel.add(lblFeature[i]);
// add 2 more lables to the same row
JLabel l=new JLabel(strHeader[i], JLabel.RIGHT);
l.setBackground(new Color(220,255,220));//.lightGray);
featurePanel.add(l);
featurePanel.add(new JLabel("", JLabel.LEFT));
}

This is my code to print the jtable on frame

I added MouseListener to select a particular row from table,the content of row is getting printed on console but I want to print this content on new frame what should I do for this.
I attached my code along with the screenshot of the table.
thanks for help.
This is my code.
final JTable table = new JTable(data, columnNames);
JScrollPane scrollPane = new JScrollPane( table );
cp.add(scrollPane,BorderLayout.CENTER);
frame.add(cp);
frame.setSize(300,300);
frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
frame.pack();
frame.setVisible(true);
table.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e){
if(e.getClickCount()==1){
JTable target = (JTable)e.getSource();
System.out.println(target);
int row = target.getSelectedRow();
System.out.println(row);
Object [] rowData = new Object[table.getColumnCount()];
Object [] colData = new Object[table.getRowCount()];
for(int j = 0;j < table.getRowCount();j++)
for(int i = 0;i < table.getColumnCount();i++)
{
rowData[i] = table.getValueAt(j, i);
System.out.println(rowData[i]);
}
}
}
});
}
First of all, if you make a graphical interface with swing, you can't use System.out.print.
You need to set every row in a Label and print it out that way. If it is a Label then you can select it with your mouse
In the Mouse Listener method, Call the new JFrame,
in that JFrame , put the Contents of selected Row to Constructor Parameters.
JFrame newframe=new JFrame("Selected Contents);
When you output the result (System.out.println(rowData[i]);) just create a new JFrame and place the text you want to output here :
...
JFrame secondFrame = new JFrame();
JPanel myPanel = new JPanel();
for(int j = 0;j < table.getRowCount();j++){
for(int i = 0;i < table.getColumnCount();i++){
rowData[i] = table.getValueAt(j, i);
JLabel label = new JLabel(rowData[i]);
myPanel.add(label);
}
}
secondFrame.add(myPanel);
secondFrame.setVisible(true);
....

Arrays not properly sorting

Good afternoon. I have created an application for an introductory java course that allows a user to sort their DVD collection by title, studio, or year. The application also allows the user to add additional DVD's to their collection, thus enlarging their arrays. The code properly compiles, but there is clearly something wrong as the titles, studio, and years are mixing themselves up. To be clear, this code is from a textbook and is part of a lab that requires the use of the exact methods, packages, etc. that you see in the code. I'm not asking for advice on how to make the code more efficient (although that is welcome as I am learning), but specifically what is wrong with the code provided causing the "scramble". Here is the code I have:

Here is a screenshot to give you a sense of what I mean be "scrambled".
Obviously, all of the titles should be in the title column, studios in studio, and years in year.
As always, I appreciate the guidance.
The problem is this line
doc.insertString(doc.getLength(), year[j] + "\t", textPane.getStyle("regular"));
where you put a tab ("\t") after the year but instead you want a newline ("\n"). So the line becomes
doc.insertString(doc.getLength(), year[j] + "\n", textPane.getStyle("regular"));
Do you simply miss a newline after adding the year of a DVD to the document? I.e.
doc.insertString(doc.getLength(), year[j] + "\n", textPane.getStyle("regular"));

table with buttons

I want to create a column and install a button in this last column in this table.
public JPanel pinakas(String[] pinaka) {
int sr = 0;
//int ari8mos =0;
String[] COLUMN_NAMES = {"Κωδικός", "Ποσότητα", "Τιμή", "Περιγραφή", "Μέγεθος", "Ράτσα"};
//pio panw mporoume na pros8esoume ws prwto column to "#", wste na deixnei ton ari8mo ths ka8e kataxwrhshs
DefaultTableModel modelM = new DefaultTableModel(COLUMN_NAMES, 0);
JTable tableM = new JTable(modelM);
JPanel mainPanel = new JPanel(new BorderLayout());
mainPanel.add(new JScrollPane(tableM), BorderLayout.CENTER);
Display disp = new Display();
while (pinaka[sr] != null) // !!!!tha ektupwsei kai mia parapanw "/n" logo ths kataxwrhshs prwtou h teleytaiou mahmatos
{
String[] temp5 = disp.lineDelimiter(pinaka[sr],6, "#");
Object[] doge = { temp5[0], temp5[1], temp5[2], temp5[3], temp5[4], temp5[5]};//edw mporoume sthn arxh na valoume to ari8mos gia na fainetai o ari8mos twn kataxwrhsewn
modelM.addRow(doge);
sr++;
//ari8mos++;
}
return mainPanel;
}
Table Button Column shows one possible solution.
