Sir,
I have a textedit which is the child widget of another parent. I have implemented the mouseDoubleClickEvent on the text edit and my requirement is that when I doubleclick on a line, I should get that entire line. Here is a part of my code:
Qt Code: 
  1. if( e->type() == QEvent::MouseButtonDblClick )             // Mouse Double clicked 
  2.    {
  3.       int  *para1,*para2,*index1,*index2; 
  4.       if( te->hasSelectedText() )
  5.       {
  6.        system("echo mouse clicked");
  7.        te->getSelection(para1,index1,para2,index2,0);
  8.       }
  9.  
  10.       QString line=te->text(*para1);
  11.      // print line in another widget for testing purpose
  12.      //call to another function      
  13.       return true;
  14.     }
To copy to clipboard, switch view to plain text mode 
Now, when I doubleclick the mouse, I could not see the output on console. And when I remove the if -condition inside, I could see the output on console.But the program is exiting itself by reporting "Bus error" on the console. Kindly help me in solving this problem.
Thanks and regards,
Sarma.
