About windows
Windows form the interface between the user and a PowerBuilder application.
Windows can display information, request information from a user,
and respond to the user’s mouse or keyboard actions.
A window consists of:
-
Properties that define
the window’s appearance and behaviorFor example, a window might have a title bar or a minimize
box. -
Events
Windows have events like other PowerBuilder objects.
-
Controls placed in the window
At the window level
When you create a window, you specify its properties in the
Window painter’s Properties view. You can also dynamically
change window properties in scripts during execution.
You can write scripts for window events that specify what
happens when a window is manipulated. For example, you can connect
to a database when a window is opened by coding the appropriate
statements in the script for the window’s Open event.
At the control level
You place PowerBuilder controls, such as CheckBox, CommandButton,
or MultiLineEdit controls, in the window to request and receive
information from the user and to present information to the user.
After you place a control in the window, you can define the
style of the control, move and resize it, and build scripts to determine
how the control responds to events.
