Hi Friends I am newbie in this form .I have question in qt software development. i want to know how to connect one form to another form on pushbutton clicked with connect signal.

@vivekyuvan I assume you execute the code bellow in one of both forms which has the button you want to connect.

MyForm2 *form2 = new MyForm2();
connect(this, pushButton, SIGNAL(clicked()), form2, SLOT(doSomething()));
