\title Simple Anchor Layout Example

|
\brief Demonstrates anchor layout on a graphics view scene.
|
|
|
|
The Simple Anchor Layout example shows the basic use of the
|
|
QGraphicsAnchorLayout class.
|
|
|
|
\image graphicssimpleanchorlayout-example.png
|
|
|
|
The example starts by creating a QGraphicsScene (\c scene), 3 widgets
|
|
(\c a, \c b, and \c c), and a QGraphicsAnchorlayout (\c layout).
|
|
|
|
\quotefromfile graphicsview/simpleanchorlayout/main.cpp
|
|
\skipto QGraphicsScene
|
|
\printuntil QGraphicsAnchorLayout
|
|
|
|
First it anchors the top left corner of item \c a to the top left
|
|
corner of \c layout. This can be done in two steps:
|
|
|
|
\skipto layout->addAnchor(a
|
|
\printto adding
|
|
|
|
Or in one step:
|
|
|
|
\skipuntil [adding a corner anchor]
|
|
\printline layout->addCornerAnchors(a, Qt::T
|
|
|
|
Then the right anchor of \c a is anchored to the left anchor of
|
|
\c b, and the top of item \c b is anchored to the bottom of \c a.
|
|
|
|
\skipuntil [adding anchors]
|
|
\printto adding anchors
|
|
|
|
Place a third widget \c c under widget \c b:
|
|
|
|
\skipuntil third widget
|
|
\printline AnchorBottom
|
|
|
|
Items \c b and \c c are anchored to each other horizontally:
|
|
|
|
\skipto Qt::Horizontal
|
|
\printline Qt::Horizontal
|
|
|
|
Item c is anchored to the bottom right point of \c layout
|
|
|
|
\skipuntil corner of the layout
|
|
\printline Qt::BottomRightCorner
|
|
|
|
Finally, QGraphicsWidget \c w is displayed in QGraphicsView \c view.
|
|
|
|
\skipto QGraphicsWidget
|
|
\printuntil app.exec()
|
|
