1 Geometry Manager Overview
One of the more difficult aspects of programming a graphically oriented application is positioning the user interface components on the screen. Developers often have to manually place buttons, size dialog boxes, and draw frames and titles. The GEOS Geometry Manager lets you ignore most of these issues.
The geometry manager allows you to ignore position, size, and spacing of your generic UI components; if you use visual objects, the geometry manager can calculate object sizes and positions, dynamically changing them as necessary. Because the geometry manager works at run-time, you have to do very little in the way of screen management. Instead, you can set various attributes and hints to fine-tune your UI's appearance.
