![]() ![]() 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. Int smartSpacing( QStyle ::PixelMetric pm) const Int doLayout( const QRect &rect, bool testOnly) const QLayoutItem *takeAt( int index) override Void setGeometry( const QRect &rect) override QLayoutItem *itemAt( int index) const override Qt ::Orientations expandingDirections() const override Void addItem( QLayoutItem *item) override class FlowLayout : public QLayoutĮxplicit FlowLayout( QWidget *parent, int margin = - 1, int hSpacing = - 1, int vSpacing = - 1) Įxplicit FlowLayout( int margin = - 1, int hSpacing = - 1, int vSpacing = - 1) It is a custom layout class that arranges its child widgets horizontally and vertically. For more information, visit Building and Running an Example. To run the example from Qt Creator, open the Welcome mode and select the example from Examples. The Flowlayout class mainly uses QLayout and QWidgetItem, while the Window uses QWidget and QLabel.įor more information, visit the Layout Management page.
