The 'Big Picture'

+ + +

The chart program allows users to create, save, load and visualise +simple data sets. Each data element that the user enters can be given +a color and pattern for the pie segment or bar, some label text and +the text's position and color. The Element class is used to +represent data elements. +

The program consists of a simple main.cpp that loads the chart +form. The chart form has a menubar and toolbar which provide access to +the program's functionality. The program provides two dialogs, one to +set options, and the other to create and edit a data set. Both dialogs +are launched from chart form menu options or toolbar buttons. +

The chart form's main widget is a QCanvasView which displays the +QCanvas on which we draw the pie chart or bar graph. We subclass +QCanvasView to obtain some specialised behaviour. Similarly we +subclass the QCanvasText class (used to place text items on a canvas) +since we require slightly more than the standard class provides. +

The project file, chart.pro, is used to create the Makefile that is +used to build the application. +
