    Hi all,
    Using Qt designer i created a Scroll area, and in run, dynamically adding widgets inside it...
    But unfortunately, widgets are added but scroll bar not coming...Because of this only few widgets are visible....

    I searched in forum, many r unresolved problems...
    Please help me to sort out my problem

    @
    void MainWindow::on_pushButton_clicked()
    {
    QLabel *label =new QLabel;
    label->setText("hello");
    ui->verticalLayout->addWidget(label,10);

    ui->scrollArea->widgetResizable();

    }
    @
    i set scroll bar policy as always on

      If i recall correctly "this":http://developer.qt.nokia.com/doc/qt-4.8/qlayout.html#SizeConstraint-enum is what you need.

        I guess you didn't add a layout in the QScrollArea?

        Try adding the widgets to that layout at run time then.

              Is verticalLayout inside your scrollarea?

              This is how you can do it in Qt Designer:
              Add a QScrollArea in your form
              Add some labels inside it
              Select those labels and add a vertical layout. Remember it's name and add other labels at runtime like you did.

              Of course the QScrollArea should be in a layout too, but don't use this one. I guess that is what you do.
