Detailed Description

The PySide.QtGui.QLinearGradient class is used in combination with PySide.QtGui.QBrush to specify a linear gradient brush.

Linear gradients interpolate colors between start and end points. Outside these points the gradient is either padded, reflected or repeated depending on the currently set spread method:

PadSpread (default)	ReflectSpread	RepeatSpread

The colors in a gradient is defined using stop points of the QGradientStop type, i.e. a position and a color. Use the QGradient.setColorAt() or the QGradient.setStops() function to define the stop points. It is the gradient’s complete set of stop points that describes how the gradient area should be filled. If no stop points have been specified, a gradient of black at 0 to white at 1 is used.

In addition to the functions inherited from PySide.QtGui.QGradient , the PySide.QtGui.QLinearGradient class provides the PySide.QtGui.QLinearGradient.finalStop() function which returns the final stop point of the gradient, and the PySide.QtGui.QLinearGradient.start() function returning the start point of the gradient.
