Inherits QWidget.
The QRubberBand class provides a rectangle or line that can indicate a selection or a boundary.
A rubber band is often used to show a new bounding area (as in a QSplitter or a QDockWindow that is undocking). Commonly this has been implemented using a QPainter and XOR, but this approach doesn't always work properly since rendering can happen in the window below the rubber band, but before the rubber band has been "erased".
You can create a QRubberBand whenever you need to render a rubber band around a given area (or to represent a single line), then call setGeometry(), move() or resize() to position and size it; hiding (or destroying) the widget will make the rubber band disappear. The rubber band can be a Rectangle or a Line, depending on the shape() it was given when constructed.
QRubberBand::Line | |
QRubberBand::Rectangle |
Destructor.
Virtual function that draws the contents of a QRubberBand using painter p.
The drawing is themed (using QStyle), but you can reimplement it to achieve custom effects.
Virtual function that draws the mask of a QRubberBand using painter p.
The drawing is themed (using QStyle), but you can reimplement it to achieve custom effects.
Moves the rubberband to point (x, y).
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Moves the rubberband to point p.
Resizes the rubberband so that its width is width, and its height is height.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Resizes the rubberband so that its new size is size.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Changes the rubberband's geometry to have a top-left corner of (x, y), a width of w, and a height of h.
Returns the shape of this rubber band. The shape can only be set upon construction.
