.h file

Qt Code: 
  1. #include"ui_titleForm2.h"
  2. #include<QDialog>
  3.  
  4. class TF2 : public QDialog, public Ui::TitleForm2
  5. {Q_OBJECT
  6. public:
  7. 	TF2(QWidget *parent=0);
  8. public slots:
  9. 	void hide(bool);
  10. };

and .cpp file
Qt Code: 
  1. #include "titleForm2.h"
  2. #include<QTableWidget>
  3. #include<iostream>
  4. TF2::TF2(QWidget *parent):QDialog(parent),TitleForm2()
  5. {	setupUi(this);
  6. 	tableWidget->setVisible(false);
  7. 	connect(pbnOk,SIGNAL(toggled(bool)),tableWidget,SLOT(setVisible(bool)));
  8. 	connect(pbnOk,SIGNAL(toggled(bool)),this,SLOT(hide(bool)));
  9.  
  10. }	
  11.  
  12. void TF2::hide(bool b)
  13. {	//control not reaching here
  14. 	tableWidget->setVisible(b);
  15. 	std::cout<<" "<<b<<" |";
  16. }

i has debugged that my code is not reaching to respective commented line. I has connected this signal in designer also.

and main is

Qt Code: 
  1. #include<QApplication>
  2. #include"titleForm2.h"
  3.  
  4. int main(int argc, char**argv)
  5. {
  6. 	QApplication a(argc,argv);
  7.  
  8. 	TF2 t;
  9. 	t.show();
  10.  
  11. 	return a.exec();
  12. }

In this i couldn't figure outt why this signal is not getting connected.
