Member Function Documentation

setGeometry()

void PixmapWidget::setGeometry ( const QRectF &  rect )

inlineoverridevirtual

This virtual function sets the geometry of the QGraphicsLayoutItem to rect, which is in parent coordinates (e.g., the top-left corner of rect is equivalent to the item's position in parent coordinates).

You must reimplement this function in a subclass of QGraphicsLayoutItem to receive geometry updates. The layout will call this function when it does a rearrangement.

If rect is outside of the bounds of minimumSize and maximumSize, it will be adjusted to its closest size so that it is within the legal bounds.

Reimplemented from QGraphicsLayoutItem.

Here is the caller graph for this function:

sizeHint()

QSizeF PixmapWidget::sizeHint ( Qt::SizeHint  which, const QSizeF &  constraint = QSizeF()  ) const

inlineoverrideprotectedvirtual

This pure virtual function returns the size hint for which of the QGraphicsLayoutItem, using the width or height of constraint to constrain the output.

Reimplement this function in a subclass of QGraphicsLayoutItem to provide the necessary size hints for your items.
