The default spacing for sublayouts, when the parent is a QLayout, will be determined by querying the spacing of the parent layout.Äocumentation contributions included herein are the copyrights of By using the AutoScrollPosition property of the FlowLayoutPanel: For instance, below, I have created a form with a button at the top and a FlowLayoutPanel docked to the bottom. The default spacing for top-level layouts, when the parent is a QWidget, will be determined by querying the style. SmartSpacing() is designed to get the default spacing for either the top-level layouts or the sublayouts. Return static_cast (parent) - >spacing() Return pw - >style() - >pixelMetric(pm, nullptr, pw) When one line is filled with the components, the next new component is added to the next line below. Int FlowLayout ::smartSpacing( QStyle ::PixelMetric pm) const FlowLayout manager class positions the components in a container within a line from left to right, starting from top to bottom. We start off by looking at the constructor: doLayout() lays out the layout items, while the smartSpacing() function calculates the spacing between them. 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.
