How to Define Events for RibbonBar Controls

Learning to define user events for items in the RibbonBar control feels like a lot of trial and error.
Different items support different events. Same event type requires different parameters.
My aim with this article is to take "... and error" out of your RibbonBar coding.
For each ribbon item type you get user event definitions that work.

 

 

      

Each ribbon item has its own XML element (here: Print Title is a CheckBox).
Each item binds specific user events via properties (here: Clicked on CheckBox binds to ue_PrintTitle)
Each user event must have the correct parameter list (here: Clicked event for CheckBox always requires al_handle while no other parameters allowed)
Each item type has its own PowerScript class and functions to obtain the object (here: Obtain class = RibbonCheckBoxItem via function GetCheckBox)

Implementing OAuth 2.0 Authorization with PowerBuilder 2019 R2

A Simple Methodology for Complex Resizing Scenarios Using the PFC

The Resize service included in the PowerBuilder Foundation Class (PFC) framework is a powerful, yet easy-to-use tool in the developer’s toolbox. Due to several factors, however, many PB developers struggle to make the Resize service perform as they would like, particularly when the layout of window controls and/or the desired resizing behavior steps become non-trivial… and often the developer ends up getting frustrated. As a result, the desired functionality is frequently omitted or severely curtailed.

The issue is not that the Resize service is unable to perform the desired task(s) – I believe it can, in many (perhaps not all) cases. The real issue is learning how to effectively utilize the functionality that already exists. There admittedly is not a lot of instructional material available on how to use the PFC in general and the Resize service in particular, so I’ve created an easy-to-follow methodology you can use to make the Resize service do what you want instead of the Resize service making you to do what it wants.

As you’ll soon see, the steps I describe in this tutorial are simple, yet they can be quickly applied to complex resizing scenarios. I’m also going to give you some free code that implements a couple of handy resize-related features you may want to add to your projects.

Quick start for contributing to Open Source PFC

Given that not everyone is fluent in using Git and or Github (where the Open Source PFC is hosted now), I put together a quick introduction in how to get started.  The video below walks through the steps, which in summary are:

  • Create a GitHub account if you don't already have one.  https://github.com/join
  • Navigate to the Open Source PFC and "Fork" a copy of the code into your account.  The 2019 version of the PFC can be found at: https://github.com/OpenSourcePFCLibraries/2019
  • Chose Code -> Clone and copy the HTTPS URL for your fork.
  • Open the PowerBuilder 2019 IDE and with no workspace open select File -> Connect to Workspace.
    • Source Control System:  Choose Git
    • Repository URL: Paste in the URL you copied above
    • Workspace File: Give it any name you choose
    • User ID:  Your Github user id (normally your email address)
    • Password:  Your Github password
    • Checkout Directory:  Select or create a new empty subdirectory on your local machine for the code to be copied to
  • Wait until the source code is downloaded and refreshed (12 to 15 minutes)
