I jus debugged this piece of code and the compiler said no signal generated..
here topic is QlineEdit and i wanna see if the line changes so i can save the values of line to my variable...

Qt Code: 
  1. if( connect(&topic,SIGNAL(textChanged(QString &)),this,SLOT(setText(QString &))))
  2. 		{topicValue = topic.text();}
  3.  
  4. if( connect(&date,SIGNAL(textChanged(QString &)),this,SLOT(setText(QString &))))
  5.    		{dateValue = date.text();}
  6.  
  7. if( connect(&data,SIGNAL(textChanged(QString &)),this,SLOT(setText(QString &))))
  8.    		{dataValue = data.text();
  9.    	 qDebug() << dateValue;
  10.  
  11. }
To copy to clipboard, switch view to plain text mode
