    <p>I have a problem with an action listener after I draw a line, basicly it works just one time, for example, my application is downloading an image, than u pick two points, first with left button mouse, second with right button, than u click "connect points" button, and it is drawing a line. And this works, I can do it with many lines etc. BUT when I close an window with image and reload it the "connect points" button stops working. Dk what to do with it. Here is the code:</p> <p>the painting line part:</p> <pre><code>public void paint(Graphics g) { super.paint(g); myPaint(g); } private void myPaint(Graphics g) { g.drawLine(lx1, ly1, px2, py2); } } </code></pre> <p>ActionListener part:</p> <pre><code>public void actionPerformed(ActionEvent e) { if(e.getSource()==painterka){ Graphics g = imadzysko.getGraphics(); paint(g); lx1=0; ly1=0; px2=0; py2=0; } } </code></pre> <p>Panel with graphic part:</p> <pre><code>void diagramKY (JFrame windower, String tyt, String content) { Listener listener = new Listener(); panelik.setLayout(null); painterka = new JButton("Connect Points"); windower = new JFrame(""); windower.setTitle(tyt+" - diagram"); windower.setSize(800, 600); windower.setVisible(true); windower.setLocationRelativeTo(null); URLdownloader.fileUrl("http://stooq.pl/c/?s="+content+"&amp;c=1d&amp;t=l&amp;a=lg", content+".png",""); imadzysko = new ImagePanel(new ImageIcon(content+".png").getImage()); panelik.add(imadzysko); panelik.add(painterka); imadzysko.addMouseListener(new MyMouseListener()); painterka.addActionListener(listener); Insets insets = panelik.getInsets(); Dimension size = imadzysko.getPreferredSize(); imadzysko.setBounds(20 + insets.left, 20 + insets.top, size.width, size.height); size = painterka.getPreferredSize(); painterka.setBounds(630 + insets.left, 20 + insets.top, size.width, size.height); panelik.repaint(); imadzysko.repaint(); windower.add(panelik); </code></pre> <p>well, any suggestions? :)</p>

    2. COAlso, in code snippets *or* self-contained examples. 1) Use the code formatting button. 2) Use a consistent & logical indent. Code indenting is intended to help people understand the flow or a program, and that source reads like a dog's breakfast. 3) remove redundant white space lines. E.G. there is no need for 3 blank lines after `py2=0;`.

    3. COAny reason you have windower as a parameter? The first thing you do is to overwrite it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
