Chapter 6 - Creating Graphic Objects
Draw ing Ob jects
To display any graphics objects on the OIT screen you must either create them using the drawing tools included
with EasyBuilder, import them from another applications program, or select from the many choices available in the
graphics libraries included with EasyBuilder.
This chapter shows you how to create, use, and save graphics objects in EasyBuilder. You have learned from
previous chapters how graphics objects are placed onto windows. In this chapter, we concentrate on how to create
graphics objects.
Using the Draw ing Tools
Several drawing tools are provided in EasyBuilder to make it easier to create graphics objects. With these tools, you
can create simple geometric shapes such as straight lines, circles, rectangles, and polygonal shapes. You can also
combine several various geometric shapes to form complex shapes that can be stored into one of the graphics
libraries for later retrieval.
The Line Tool
Use the Line tool to create straight lines on a window. Each line that you create has three parameters associated
with it: length, thickness, and color.

5. Move the mouse cursor over to the work area of EasyBuilder onto the window that you are
currently editing. The mouse cursor has changed from an arrow to a crosshair cursor.
6. Click to mark the beginning of the line. Move the mouse to the location where the end of the
line should be. Click the mouse cursor again to mark the end of the line. The line object is
formed and displayed on the window screen with small white square blocks around the
boundaries of the line.
