The QGraphicsRectItem class provides a rectangle item that you can add to a QGraphicsScene.
- Since
- 4.2
\inmodule QtWidgets
To set the item's rectangle, pass a QRectF to QGraphicsRectItem's constructor, or call the setRect() function. The rect() function returns the current rectangle.
QGraphicsRectItem uses the rectangle and the pen width to provide a reasonable implementation of boundingRect(), shape(), and contains(). The paint() function draws the rectangle using the item's associated pen and brush, which you can set by calling the setPen() and setBrush() functions.
- Note
- The rendering of invalid rectangles, such as those with negative widths or heights, is undefined. If you cannot be sure that you are using valid rectangles (for example, if you are creating rectangles using data from an unreliable source) then you should use QRectF::normalized() to create normalized rectangles, and use those instead.
