SynEdit Accessibility Support

[pyscripter 583]

Firstly, let me say that my work on SynEdit has moved back to pyscripter/SynEdit for reasons explained here.

 

The newest enhancement to SynEdit is accessibility support.  Now, SynEdit fully supports screen readers such as Windows Narrator and NVDA. The support is much better than, for instance, in Visual Studio Code.  The implementation is not based on the older Microsoft Active Accessibility (MSAA), but on the newer Microsoft UI Automation. Microsoft UI Automation has been around since 2005 and is available to all Windows versions, since Windows XP. In addition to making applications accessible, it can also be used by automated UI testing tools.

 

Despite been available for almost 20 years, Delphi does not provide the relevant header translations (See RSP-41898), which complicated the implementation. I also could not find any other complete Delphi implementation of UI automation. So, the SynEdit implementation may serve as a guide to how to implement UI Automation in other controls.  Further details can be found here.
