Introduction
Graphical output is performed using the following objects:
Graphical Output | |
---|---|
Circle | draws circles, arcs and pie charts |
Ellipse | draws ellipses |
Marker | draws a series of polymarkers |
Poly | draws lines |
Rect | draws rectangles |
Image | displays or prints Bitmaps, Icons and Metafiles |
Text | displays or prints graphical text |
These graphical objects can be drawn in (that is, be the children of) a wide range of other objects including a Form, Static, Printer and Bitmap.
Additional graphical resources are provided by the following objects. These are unusual in that they are not visible except when referenced as the property of another object:
Resource | |
---|---|
Font | loads a font |
Bitmap | defines a bitmap |
Icon | defines an icon |
Metafile | loads a Windows Metafile |
Graphical objects are created, like any other object, using ⎕WC
and have properties that can be changed using ⎕WS
and queried using ⎕WG
. Graphical objects also generate certain events.
