I have to change my program's GUI implemented in Swing. Now I have many charts in seperate windows and I want to change it so they all display in only one. The constraction of the orginal version was that JFrame had a JPanel field. JFrame had no set layout.
private void initComponents() {// GEN-BEGIN:initComponents
getContentPane().setLayout(null);
setTitle("Wykres");
addComponentListener(new java.awt.event.ComponentAdapter() {
public void componentResized(java.awt.event.ComponentEvent evt) {
resizedWindow(evt);
}
});
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
exitForm(evt);
}
});
java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
setBounds((screenSize.width - MIN_WIDTH) / 2, (screenSize.height - MIN_HEIGHT) / 2, MIN_WIDTH, MIN_HEIGHT);
}
JPanel was declared as follows:
BorderLayout borderLayout = new BorderLayout();
borderLayout.setHgap(0);
borderLayout.setVgap(0);
drawPanel = new JDrawPanel();
drawPanel.setLayout(borderLayout);
drawPanel.setComponentOrientation(ComponentOrientation.UNKNOWN);
setContentPane(drawPanel);
If I remove inheritance by JFrame and add inheritance by JPanel, the method paintComponent is not called. I think the reason is bad layout settings. However program calculates the distances from the edges, and I don't want to change it. How can I easily edit this program?
I also generated new GUI in NETBEANS
public class ViewPanel extends javax.swing.JFrame {
public ViewPanel() {
// initComponents();
}
public ViewPanel(JPanel histo, JPanel dystrybu, JPanel time){
initComponents(histo, dystrybu, time);
}

setTitle("zaleznosc czasowa");
