Opening window by clicking Paint Area !

[Fidel Edwards]

Hi friends,


I am new to Java swing ! Any body can tell me that in this code

   class paintSSPanel extends JPanel {
    private int yy = 14;
    private int x1 = 15;
    
    
    
    paintSSPanel() {
      setPreferredSize(new Dimension(prefWW, (data.size() + 1) * 14));
      setBackground(VLG);
      setBorder(new LineBorder(bgclr, 5));
    } // end paintSSPanel()
// HERE I WANT TO CLICK , ON CLICK I WANT TO OPEN NEW WINDOW
    public void paintComponent(Graphics g) {
      super.paintComponent(g);

      String[] imn = null;
      int y2 = 0;
      g.setColor(Color.black);
      g.setFont(new Font("SanSerif", Font.PLAIN, MU.FONT_SIZE_PREF + 1));

      ListIterator it = data.listIterator();

      while (it.hasNext()) {
        g.drawString(((String) (it.next())), x1, ++y2 * yy);// #Paint  Area
      }
    } // end paintComponent()
  } // end paintSSPanel  

Whether is it possible to click on #Paint Area and open new window or frame or dialog ?

Thanks in advance !

You would never add code like that to the paintComponent() method.

You add a MouseListener to the panel. Read the section from the Swing tutorial on How to Write a Mouse Listener for more information.

Thanks Rob for reply!
But I want to open a new window as user click on the list item of Paint Area .Is is possible or not ?

I already gave the answer, there is no need to repeat myself.

Of course it would appear to me it would be easier to just use a JList so you don't reinvent the wheel.

Actually your approach is complicated since you want to detect the string drown on the panel by using a mouse click.
You can do that with the following approach ( not recommended; the recommended is to use a list on the panel)

for each String draw a rectangular boundary ( g.drawRect..) and over the rectangle location put you string ( g.drawString(...))
you add a mouse Listener to the panel
if mouse is being clicked, you get the X, and Y location of the mouse and determine if it is in the boundary of your String ( actually you define your boundary
for each string ), then you retrieve it from the definition store ( some kind of data structure which maps you String literal to location on the screen, this defintion store is build relatively w.r.t panel size; so any panel resizing, will re-map the String literal to new location so that you can draw them again)

Just an idea and thoughts
