User Objects

Applications often have features in common. If you find you are repeatedly using the same application feature, define a user object in the User Object painter; you can then use the object in multiple places.

For example, you might often reuse features like the following:

• A processing package that calculates commissions or performs statistical analysis
• A Close button that performs a certain set of operations and then closes the window
• DataWindow controls that perform standard error checking
• A list that includes all departments
• A predefined file viewer that you plug into a window

Creating and using class and visual user objects are discussed in the PowerBuilder Users Guide. PowerBuilder .NET also allows you to use customized or third-party WPF controls. See Third-Party and Custom Controls.

• Third-Party and Custom Controls
  You can use custom and third-party WPF controls in PowerBuilder .NET, in WPF windows and DataWindow object. Using custom and third-party controls allows you to extend the software system to support a wider range of applications.
