.h file



#include"ui_titleForm2.h"
#include<QDialog>

class TF2 : public QDialog, public Ui::TitleForm2
{Q_OBJECT
public:
TF2(QWidget *parent=0);
public slots:
void hide(bool);
};


and .cpp file


#include "titleForm2.h"
#include<QTableWidget>
#include<iostream>
TF2::TF2(QWidget *parent):QDialog(parent),TitleForm2()
{ setupUi(this);
tableWidget->setVisible(false);
connect(pbnOk,SIGNAL(toggled(bool)),tableWidget,SL OT(setVisible(bool)));
connect(pbnOk,SIGNAL(toggled(bool)),this,SLOT(hide (bool)));

}

void TF2::hide(bool b)
{ //control not reaching here
tableWidget->setVisible(b);
std::cout<<" "<<b<<" |";
}


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

and main is




#include<QApplication>
#include"titleForm2.h"

int main(int argc, char**argv)
{
QApplication a(argc,argv);

TF2 t;
t.show();

return a.exec();
}


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

Hide does not take a boolean as an argument.

[jacek]

Is that button checkable?

[quickNitin]

i redefined hide() again in my class unknowingly but i think its going to create any isssues. is it?
About checkable nature of button , i hadnot set that explicititly. I will try to set that.

[quickNitin]

yes, makeing button checkable did helped and it is working.
