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)

Since PowerBuilder 2017 R2, we have a new HTTPClient object, which is a base object for sending HTTP requests and receiving HTTP responses from a resource identified by a URI. Compared to the Inet object, the HTTPClient object is easier to use and supports more methods (Get/Post/Put/Delete) and more SSL protocols (TLS 1.0, TLS 1.1, TLS 1.2, SSL 2.0, and SSL 3.0).

Among other things, the HTTPClient can be also used to consume SOAP Web services. This is particularly useful as the Web Service Proxy has many limitations and defects calling SOAP Web services such as not supporting TLS 1.2. This article is to show how you can use the new HTTPClient to call your existing SOAP Web services instead.
