Recuce boundary space in QGroupBox/QFrame

[prashant]

How to reduce boundary space (horizontal/vertical) in QGroupBox?

The button are added in a horizontal layout and then layout has been set for GroupBox.

self.horizontalGroupBox.setLayout(layout)

self.horizontalGroupBox.setLayout(layout)

To copy to clipboard, switch view to plain text mode 

This is also relevant for QFrame. It also takes some extra space as visible in the image.

QLayout::setContentsMargins() and QWidget::setContentsMargins().
