- This program is a demo of both object oriented programming and using
- the GRAPH unit. The program should be fairly self explanatory with a
- couple of small points:
- 1) You must have a mouse and mouse driver installed.
- 2) You must have a copy of the appropriate BGI driver file for your
- display type in the current directory (e.g. EGAVGA.BGI).
- 3) Click in the 'Q' box to quit.
- 4) The 'C' box clears the drawing area.
- 5) Clicking in the lower left window changes the type of style that
- can be modified in the lower right window.
- 6) Clicking in the 'ABC' box selects text entry. You must then go to
- the drawing window and use the mouse to enter a text box. This
- box represents the size of a single character. Note you may
- adjust both the height and width of characters drawn. Typing a
- character displays it on the screen, no editting of any sort is
- provided.
- 7) To compile the program, simply do a make or build on PAINT.EXE.
- I've written an equivalent program using Microsoft's Quick Pascal
- and the MSGRAPH unit that comes with it. The design is identical and
- the functionality is just a matter of the differences in how the two
- graphics packages are written. It does provide an interesting
- comparison of the object oriented approaches in Turbo Pascal and Quick
- Pascal. The Quick Pascal version may be found in the Quick Pascal
- section of Microsoft's Programming forum on Compuserve.
- Have fun!
