@veera If you don't want to open them as windows than don't do it. It looks like you're using dialogs - dialogs are per definition windows! Add those widgets to their parent widget.
Qt designer form class is widget .....after that how to add widgets to their parent widget ?
Well... every widget has the setParent(QWidget *parent) function. is that not working for you?
