Hi to all,
I solve this problem by myself. Steps to solve it are as:

1> Declare a in header file of calling class.
QVector "<"classNameOfWidgetToUse *> m_ptr;

2> In cpp file of calling class (in constructor or any function where u want to use) define

classNameOfWidgetToUse *obj = new classNameOfWidgetToUse;
m_ptr << obj;
ui.objOfCallingClassWhereUWantToWidget->addWidget(m_ptr[i]);

where i is an integer value.
