Palm OS Platform Screen Painting


This option lets the Sourcerer draw various graphics objects on the screen. They include

Each object will require a location as well as some additional information to draw it on the screen. All of these parts have an option for the draw mode. For the line, filled rectangle, filled rounded rectangle and border, the "gray" draw mode produces dotted graphics, and the "invert" mode will draw black on green and green on black. For text strings, the "gray" draw mode is identical to plain text, and the "invert" mode always draws green text on a black background.

When the screen is cleared, no parts are removed from the program, but they will become invisible until the next time they are painted.

The option to paint all parts may also be available, if it is appropriate.
