In this chapter, we will start developing the last application of this book–a spreadsheet program capable of calculating numerical expressions as well as cutting and pasting cells with relative references. Similar to the word processor in the previous chapters, the spreadsheet program cuts and pastes ASCII and Unicode text as well as application-specific information. Moreover, it is possible to change the font and color of the cells and their horizontal and vertical alignment.
In this chapter, we will look at the following:
Mouse and keyboard input
Drawing a spreadsheet
Saving and loading the spreadsheet
Cutting, copying, and pasting cell blocks
Fonts, colors, and alignments of cell blocks
