    hLayout3 is not a widget, but a layout. Instead, do something like this:

    @
    scrollArea->widget()->setLayout(hLayout3);
    @

        Perhaps widget() returns 0, and you need to create such a widget first yourself.
        Try:
        @
        QWidget* baseArea = new QWidget(0);
        baseArea->setLayout(hLayout3);
        scrollArea->setWidget(baseArea);
        @

          I have written the following two lines too
          @

          QHBoxLayout *hLayoutScrollArea = new QHBoxLayout;
          hLayoutScrollArea->addWidget(scrollarea);

          @

            That will put the scroll area itself in a layout, but without something like this, will not do anything:

            @
            theParentWidgetOfYourScrollArea->setLayout(hLayoutScrollArea);
            @

                Found tht something is displayed, but its not legible.

                I have put the scroll area into another layout. and finally all the layouts are put into one single vLayout.
                I have done this so as to display in another class containing tabs, so the final vLayout goes into the another widget and then displayed on tabs

                  Make sure that the top level layout (there can be only one!) is actually set on the top level widget. Otherwise, your dialog will not properly layout at all.

                    the thing is, every other widget in the form, other than the scrollares is displayed. Its the jus the scrollarea which is messed up

                          :D i got it right. It was jus that the widgets were not stretched. There is a property called setWidgetResizable(true) which automatically adjusts the size of widgets. :)

                          solution:
                          after you create a scroll area jus add the following line
                          @
                          scrollarea->setWidgetResizable(true);
                          @

                          Au Revoir :D
