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();
}

#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.
