Detailed Description

The PySide.QtGui.QPolygon class provides a vector of points using integer precision.

A PySide.QtGui.QPolygon object is a QVector < PySide.QtCore.QPoint >. The easiest way to add points to a PySide.QtGui.QPolygon is to use QVector ‘s streaming operator, as illustrated below:

polygon = QPolygon()
polygon << QPoint(10, 20) << QPoint(20, 30)

In addition to the functions provided by QVector , PySide.QtGui.QPolygon provides some point-specific functions.

Each point in a polygon can be retrieved by passing its index to the point() function. To populate the polygon, PySide.QtGui.QPolygon provides the setPoint() function to set the point at a given index, the setPoints() function to set all the points in the polygon (resizing it to the given number of points), and the putPoints() function which copies a number of given points into the polygon from a specified index (resizing the polygon if necessary).

PySide.QtGui.QPolygon provides the PySide.QtGui.QPolygon.boundingRect() and PySide.QtGui.QPolygon.translate() functions for geometry functions. Use the QMatrix.map() function for more general transformations of QPolygons.

The PySide.QtGui.QPolygon class is implicitly shared .

Constructs a polygon with no points.

See also

QVector.isEmpty()

Constructs a copy of the given polygon .

See also

setPoints()

Constructs a polygon from the given rectangle . If closed is false, the polygon just contains the four points of the rectangle ordered clockwise, otherwise the polygon’s fifth point is set to rectangle . topLeft() .

Note that the bottom-right corner of the rectangle is located at (rectangle. x() + rectangle. width() , rectangle. y() + rectangle. height() ).

See also

setPoints()

Constructs a polygon of the given size . Creates an empty polygon if size == 0.
