Flowlayout margins
A flow layout works with the collection view’s delegate object to determine the size. Cells can be the same sizes or different sizes. setLayout (new FlowLayout (FlowLayout. The FlowLayout class (along with a few other layout classes) allows you to set the horizontal and vertical gaps in its constructor, like so: private static final int PADDING 3 // for example. Items in the collection view flow from one row or column (depending on the scrolling direction) to the next, with each row containing as many cells as will fit. Swing tends to call margins or borders 'gaps'. doLayout() lays out the layout items, while the smartSpacing() function calculates the spacing between them. A flow layout is a type of collection view layout.

We also declare two private methods, doLayout() and smartSpacing(). These functions add items to the layout and handle their orientation and geometry. We reimplement functions inherited from QLayout. PixelMetric pm ) *> = QList < QLayoutItem () m_hSpace = int () m_vSpace = int ()

Configuration of a flow layout is very simple.
