So, I want to paint something on a Panel, using PaintComponent. But I want to do it in a Constructor. So, for example:
public class Interfata extends JPanel
{
public void paintComponent(Graphics g)
{
super.paintComponent(g);
g.setColor(Color.red);
g.drawOval(500, 500, 50, 40);
}
public Interfata()
{
// code here
}
public static void main(String[] args)
{
Interfata i = new Interfata();
}
The code should be like this model. The problem is that I don't know how to call the paintComponent method on a panel that create in the Constructor. ( Even though it may seem inefficient, I create the frame, panel and all the functions in the constructor, so, that I just have to instantiate that object in the main method). If I weren't clear enough, please do ask for any detail you may find suitable.
Edit: So to be more specific, this is how my Constructor looks like:
public Interfata()
{
// main interface
JFrame frame = new JFrame("Queue");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(1000, 450);
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
int x = (int) ((d.getWidth() - frame.getWidth()) / 2);
int y = (int) ((d.getHeight() - frame.getHeight()) / 2);
frame.setLocation(x, y);
//simulation interface
JFrame f = new JFrame("Simulare");
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f.setSize(900, 800);
int x1 = (int) ((d.getWidth() - frame.getWidth()) / 2);
int y1 = (int) ((d.getHeight() - frame.getHeight()) / 2);
f.setLocation(x1, y1);
JPanel panel = new JPanel();
panel.setLayout(null);
JPanel panel1 = new JPanel();
panel1.setLayout(null);
JLabel l1 = new JLabel("Intervalul minim de asteptare: ");
JTextArea tf1 = new JTextArea();
panel.add(l1);
l1.setBounds(5,10,200,25);
panel.add(tf1);
tf1.setBounds(200,10,300,20);
JLabel l2 = new JLabel("Intervalul maxim de asteptare: ");
JTextArea tf2 = new JTextArea();
panel.add(l2);
l2.setBounds(5,50,200,25);
panel.add(tf2);
tf2.setBounds(200,50,300,20);
JLabel l3 = new JLabel("Duarata minima pentru serviciu: ");
JTextArea tf3 = new JTextArea();
panel.add(l3);
l3.setBounds(5,90,200,25);
panel.add(tf3);
tf3.setBounds(200,90,300,20);
JLabel l4 = new JLabel("Durata maxima pentru serviciu: ");
JTextArea tf4 = new JTextArea();
panel.add(l4);
l4.setBounds(5,130,200,25);
panel.add(tf4);
tf4.setBounds(200,130,300,20);
JLabel l5 = new JLabel("Numarul de cozi: ");
JTextArea tf5 = new JTextArea();
panel.add(l5);
l5.setBounds(5,170,100,25);
panel.add(tf5);
tf5.setBounds(200,170,300,20);
JLabel l6 = new JLabel("Intervalul de simulare: ");
JTextArea tf6 = new JTextArea();
panel.add(l6);
l6.setBounds(5,210,150,25);
panel.add(tf6);
tf6.setBounds(200,210,300,20);
JButton b1 = new JButton("Simulare");
panel.add(b1);
b1.setBounds(700,100,100,35);
b1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
f.setVisible(true);
}
});
frame.setContentPane(panel);
frame.setVisible(true);
f.setContentPane(panel1);
}
What I want to do exactly, is paint something in the panel of the NEW FRAME, or more specificaly, in the frame f.

My expected result is the circle will be changed after the user input the centre coordinate of the circle and clicked redraw btn.
The problem is that you are not using never your variable drawCircle (line:
DrawPanel drawCircle = new DrawPanel();)
And when you use inside actionPerformed method, you never use that variable because it's created another instance of Circle Project. (line: CircleProject frame2 = new CircleProject();)
The drawCircle variable is from the current class you are running,so, when you instance again CircleProject, the changes inside that variabe will not have effect.
To fix that, it's not necessary to instance again, you only must use that variable.
The first thing you will have to do inside the Constructor CircleProject():
....
userInputPanel.add(gridPanel);
contentPanel.add(drawCircle);
contentPanel.add(userInputPanel);
....
The change here was only one, because you have contentPanel.add(new DrawPanel()); and that's not correct (as I said, you never are using the variable drawCircle), so, instead, you have to change it for contentPanel.add(drawCircle);
On the other hand, to avoid instancing the CircleProject you will have to remove some lines in the actionPerformed method, like:
#Override
public void actionPerformed(ActionEvent e) {
if (e.getSource() == redraw) {
String text = xTextField1.getText();
int x1 = Integer.parseInt(text);
String text1 = xTextField2.getText();
int x2 = Integer.parseInt(text1);
String text2 = yTextField1.getText();
int y1 = Integer.parseInt(text2);
String text3 = yTextField2.getText();
int y2 = Integer.parseInt(text3);
String text4 = textFieldRadiusLeft.getText();
int r1 = Integer.parseInt(text4);
String text5 = textFieldRadiusRight.getText();
int r2 = Integer.parseInt(text5);
drawCircle.setCenterColumn1(x1, y1, r1);
drawCircle.setCenterColumn2(x2, y2, r2);
}
}
I tried the program and it worked for me! I hope this also works for you :D
I'm trying to build my own calculator from scratch.
When i run my program as it is now, some of the buttons don't show up, until i hover over them with my cursor, and my bounds are all f'ed up. However when i move window.setVisible(true); to the beginning of my constructer, every bound of all the objects are placed correctly, but all my objects only show once moused-over.

How it is supposed to look. (i've hovered over all my objects manually.)
I changed your code and use layouts instead of setBouds().
Swing provide different LayoutManagers and these are used to arrange components in a particular manner. following classes are used to represents the layout managers in Swing:
1) java.awt.BorderLayout
2) java.awt.FlowLayout
3) java.awt.GridLayout
4) java.awt.CardLayout
5) java.awt.GridBagLayout
6) javax.swing.BoxLayout
7) javax.swing.GroupLayout
8) javax.swing.ScrollPaneLayout
9) javax.swing.SpringLayout etc.
each of them will arrange your components in specific order, which you can read more about it in here (more details...)

so im kinda new to programming and I'm having a weird problem. So I'm trying to add my 'Info' panel with labels in them to my 'JFrame' but when I run the program the panel doesn't show up. Also how would I make it to where the panel would appear in the top Left of the JFrame.

{
imgBackground[i] = new ImageIcon("Stage\\Forest.gif");
}
xPos = new int[] {0, imgBackground[0].getIconWidth()};
// sets the amount of time for each timer

// creates a label that displays "TIME"

I am trying to get a text input from a JTextField and displaying it on a JTextField when a button is clicked. Can anyone help please?
I know I am supposed to use getText and setText but not quite sure how I can implement this when the button is clicked. Please have a look at the code below.

You have the eventHandler, so just call responseArea.setText(textField.getText()) when handling the click on the appropriate button.

Basically change size: for panelForTextFields. From 350 to 500 for example.
To make code a bit generic I would write something like:
panelForTextFields.setSize(100, 6*80);
where 6 is count of JTextFields.
If we will go further, I would create list of JTextField like:
List<JTextField> list = new ArrayList<JTextField>();
list.add(quiz_1);
list.add(quiz_2);
list.add(quiz_3);
list.add(quiz_4);
list.add(quiz_5);
list.add(quiz_6);
and after would write:
final int GAP = 40;
panelForTextFields.setSize(100, 6*( quiz_1.getHeight() + GAP));
Since you used the same logic to configure JTextfields you can use now list like:
quiz_1 = new JTextField(8);
panelForTextFields.add(quiz_1);
quiz_2 = new JTextField(8);
panelForTextFields.add(quiz_2);
quiz_3 = new JTextField(8);
panelForTextFields.add(quiz_3);
quiz_4 = new JTextField(8);
panelForTextFields.add(quiz_4);
quiz_5 = new JTextField(8);
panelForTextFields.add(quiz_5);
quiz_6 = new JTextField(8);
panelForTextFields.add(quiz_6);
quiz_7 = new JTextField(8);
panelForTextFields.add(quiz_7);
list.add(quiz_1);
list.add(quiz_2);
list.add(quiz_3);
list.add(quiz_4);
list.add(quiz_5);
list.add(quiz_6);
list.add(quiz_7);
for(int k = 0; k<list.size(); k++){
JTextField f = list.get(k);
f.setLocation(0, k*60);
f.setSize(100, 30);
}
final int GAP = 40;
panelForTextFields.setSize(100, 6*( quiz_1.getHeight() + GAP));
