PowerBuilder supports getting secured data from the OAuth 2.0 authorization server. The Bearer access token is supported, and the following grant types are supported:
This document provides an example on how to set up OAuth 2.0 authorization workflow using the Authorization Code grant type in a PowerBuilder application.
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)
Why enhance JSON handling?
Reading and writing JSON in PowerBuilder is simple using PowerBuilder’s RESTClient object; however, the JSON needs to be in a two-dimensional format. But there are times when the JSON you are working with has multiple nested levels, especially if working with data from an external interface not under your control.
The PowerBuilder objects JSONParser and JSONGenerator can be used to parse or generate such JSON with multiple nested levels. However, a key caveat is that the JSONParser and JSONGenerator require the JSON data to be accessed through “handles”. For example, the getItemObject() returns a handle rather than the full JSON object. Compared to an object-based approach, this handle-based approach requires more coding by the developer.
Did you know that Powerbuilder 2019 could run on Linux ?
