About controls
About window controls
You place controls in a window to request and receive information
from the user and to present information to the user. For a complete
list of standard window controls, open a window in the Window painter
and select Insert>Control.
If you often use a control or set of controls with certain
properties, such as a group of related radio buttons, you can create a
visual user object that contains the control or set of controls. For
more about user objects, see Working with User
Objects.
About events
All window controls have events so that users can act on the
controls. You write scripts that determine the processing that takes
place when an event occurs in the control.
Drawing controls are usually used only to make your window more
attractive or to group controls. Only constructor and destructor events
are defined for them, but you can define your own events if needed. The
drawing controls are Line, Oval, Rectangle, and RoundRectangle.
