43 \class QGraphicsGridLayout -
44 \brief The QGraphicsGridLayout class provides a grid layout for managing -
45 widgets in Graphics View. -
46 \since 4.4 -
47 -
48 \ingroup graphicsview-api -
49 \inmodule QtWidgets -
50 -
51 The most common way to use QGraphicsGridLayout is to construct an object -
52 on the heap with no parent, add widgets and layouts by calling addItem(), -
53 and finally assign the layout to a widget by calling -
54 QGraphicsWidget::setLayout(). QGraphicsGridLayout automatically computes -
55 the dimensions of the grid as you add items. -
56 -
57 \snippet code/src_gui_graphicsview_qgraphicsgridlayout.cpp 0 -
58 -
59 The layout takes ownership of the items. In some cases when the layout -
60 item also inherits from QGraphicsItem (such as QGraphicsWidget) there will be a -
61 ambiguity in ownership because the layout item belongs to two ownership hierarchies. -
62 See the documentation of QGraphicsLayoutItem::setOwnedByLayout() how to handle -
63 this. -
64 You can access each item in the layout by calling count() and itemAt(). Calling -
65 removeAt() will remove an item from the layout, without -
66 destroying it. -
67 -
68 \section1 Size Hints and Size Policies in QGraphicsGridLayout -
69 -
70 QGraphicsGridLayout respects each item's size hints and size policies, -
71 and when a cell in the grid has more space than the items can fill, each item -
72 is arranged according to the layout's alignment for that item. You can set -
73 an alignment for each item by calling setAlignment(), and check the -
74 alignment for any item by calling alignment(). You can also set the alignment -
75 for an entire row or column by calling setRowAlignment() and setColumnAlignment() -
76 respectively. By default, items are aligned to the top left. -
