Mouse Clicked gets lost some times.

Question

Hello All,
The scenario is that i have a tree and the doubleclick on the tree node openes a view with some information. Also the node has some childrens. Sometimes when i double click the node, the tree node gets expanded but my view does not get opened. This was due to mouseclicked does not arrive with click count as 2.
In my code double click handling is done in the mouseclicked event. The code looks like
public void mouseclicked(MouseEvent ev) {
if(ev.getClickCount() == 2) {
.......//Opens a view
In some cases when i double click, mouse clicked is triggered only once with click count as one. But the mousepressed and mousereleased is triggered twice with clickcount 1 and 2 resp. I am not sure is this a valid behaviour. Please find below the traces of events.

Can anybody help me out to figure out to find what is the problem?
Thanks in advance

Answer 1

I just checked mouseClicked.. and its working fine for me.
tree.addMouseListener(new MouseListener(){
               public void mouseClicked(MouseEvent e) {
                    // TODO Auto-generated method stub
                    if(e.getClickCount() == 2)
                         System.out.println("mouseClicked");
               public void mouseEntered(MouseEvent e) {
                    // TODO Auto-generated method stub
               public void mouseExited(MouseEvent e) {
                    // TODO Auto-generated method stub
               public void mousePressed(MouseEvent e) {
                    // TODO Auto-generated method stub
               public void mouseReleased(MouseEvent e) {
                    // TODO Auto-generated method stub
});If we double click on a node which is having child nodes, then it will collapse/expand when double click on it.
In all cases I am getting the display "mouseClicked" when doing double click.
