PowerBuilder

PowerBuilder (Intermediate)

These concepts cover more advanced features and best practices in PowerBuilder. They are necessary for writing more complex and efficient PowerBuilder applications.

1. Creating a Menu Hierarchy
   • Learn to design and implement a hierarchical menu structure to organize application functions into a logical and user-friendly format.
   • Understand how to add and configure individual menu items to provide specific functionality and user actions within the application.
   • Reason: A well-organized menu hierarchy improves the navigation and usability of the application.
   • Example Task: Create a multi-level menu with file, edit, view options, and set up appropriate menu item actions.
2. Writing Code for Common Menu Items
   • Learn to write code that specifies what happens when a menu item is selected, such as opening a dialogue or performing a task.
   • Explore handling events triggered by menu item selections to execute specific code or update the application state.
   • Reason: Implementing actions for menu items ensures that user interactions trigger the correct application responses.
   • Example Task: Write code for the "Save" menu item to save the current document or data.
3. Building Application Windows
   • Learn to create MDI (Multiple Document Interface) windows that allow users to work with multiple documents within a single parent window.
   • Understand how to manage the resizing of MDI child windows to ensure they fit properly within the parent window
   • Reason: MDI applications enhance user productivity by enabling simultaneous document management.
   • Example Task: Create an MDI parent window and configure it to display multiple child windows.
4. Opening Windows and Resizing Controls
   • ​​​​​​​Learn to implement functionality for opening and displaying child windows within the MDI parent window.
   • Explore how to adjust the sizes of controls within a window to ensure they are appropriately displayed and aligned.
   • Reason: Opening child windows allows users to work with multiple documents or views simultaneously.
   • Example Task: Write code to open a new child window when a specific menu item or button is clicked.
5. Using the Application Database
   • ​​​​​​​Learn to establish a connection between your PowerBuilder application and the database to enable data operations.
   • Explore techniques for retrieving data from the database and displaying it in the application.
   • Reason: Implement a script to retrieve connection is required for retrieving, updating, and managing data.
   • Example Task: Implement a database connection and perform a test query to retrieve data from a sample table, update and delete data.
6. Creating DataWindow Objects and Managing Extended Attributes
   • ​​​​​​​Understand how to create and configure DataWindow objects to display data in various formats and styles.
   • Learn to manage and customize extended attributes for DataWindows to add additional functionality or style.
   • Reason: DataWindow objects are key components for displaying and managing data within PowerBuilder applications.
   • Example Task: Create a DataWindow object with a grid presentation style and bind it to a data source.
