JLabel is being shown in wrong place
I have a problem with GUI. In my drawing simulator, I created a JLabel that show mouseclicks coordinates. I put it on southwest of my JFrame but after each click, in addition to its first place, mouse coordinates also appear on northwest of the JFrame. I didn't understand what ths problem is.The code is here.
JLabel statusBar = new JLabel( "Mouse outside JPanel" );
Container panel;
JFrame frame = new JFrame();
panel = frame.getContentPane();
panel.add(this);
frame.setJMenuBar(jmb);
frame.add(statusBar, BorderLayout.SOUTH );
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(700,700);
frame.setVisible(true);
This is how I edit JLabel
statusBar.setText( String.format( "Clicked at [%d, %d]",
开发者_StackOverflow社区 e.getX(), e.getY() ) );
The whole code can be longer thats why iam copying some important parts
public class Tester extends JPanel implements MouseMotionListener, MouseListener {
....
This is how a draw a single line and I set the label's name here
else if(lineci == true){
if(mouseclicks == 0){
l1.point1.x = e.getX();
l1.point1.y = e.getY();
statusBar.setText( String.format( "Clicked at [%d, %d]",
e.getX(), e.getY() ) );
mouseclicks++;
}
else if(mouseclicks == 1){
l1.point2.x = e.getX();
l1.point2.y = e.getY();
statusBar.setText( String.format( "Clicked at [%d, %d]",
e.getX(), e.getY() ) );
mouseclicks = 0;
int a = l1.point2.y - l1.point1.y;
int b = l1.point1.x - l1.point2.x;
int c = (l1.point2.x * l1.point1.y) - (l1.point1.x * l1.point2.y);
l1.denklem[0] = a;
l1.denklem[1] = b;
l1.denklem[2] = c;
array.add(l1);
array3.add(l1);
repaint();
}
By the way, I 'm creating JLabel object outside the constructur of the class, just after creating class I mean.
Still same problem exists.
Instead of
frame.add(statusBar, BorderLayout.SOUTH );
Try
frame.getContentPane().add(statusBar, BorderLayout.SOUTH );
