Detailed Description

Base class for spectrum widgets.

This class is the base class for the different MDI window types in the TOPPView application. For each type of spectrum view (such as 1D view, 2D view, 3D view etc.), there must exist a corresponding class derived from this class.

In TOPPView, each PlotWidget holds an enclosed PlotCanvas with which it is paired (e.g. a Plot1DWidget holds a Plot1DCanvas) which can retrieved with the canvas() function. While the PlotCanvas does the actual drawing, the PlotWidget holds information about the axes (axis widgets), scrolling (scrollbars) etc. The PlotWidget uses a grid layout (QGridLayout) with a default 3x3 grid where the upper right corner of the grid is the canvas and the spaces left and below the canvas are for the axes widget and scrollbars.

To integrate a new spectrum view (i.e. classes derived from PlotWidget and PlotCanvas) into the TOPPView application, a class must be derived from this class which holds an instance of the PlotCanvas class as a child widget.
