Introduction to PowerBuilder

Drawing Objects

You can make use of drawing objects to improve the appearance of the window you paint. You can notice from the picture that Drag-and-Drop properties are missing for controls that fall under the Drawing category. Make a note that Drawing controls don't have any events and moreover you can't define user-defined events (details in future sessions).

The only drawing control that has interesting properties is the RoundRectangle. The CornerHeight and CornerWidth properties allow you to specify the degree of roundness that should be applied to the corners. The CornerHeight property defines how far from the corner on the vertical edges should the curve begin, while the CornerWidth property affects the same, except that it affects the horizontal edges.

Given the starting points, two for each corner, PowerBuilder calculates the smoothest possible curve between the two points closest to each corner, to produce a rounded rectangle.
