In this post, you’ll learn how the HandleException method, also known as DelphiVCL.Application.HandleException, works. It’s used to provide the application with default exception handling. If an exception passes through all the try blocks in the application code, the application automatically calls HandleException, which displays a dialog box indicating an error has occurred. Unless the exception object is EAbort, HandleException calls the OnException event handler, if one exists. Otherwise, it calls ShowException to display a message dialog box indicating an error has occurred.
To assign other exception handling codes for the application, use the OnException event handler. Learning more about the HandleException method will help you build a Python project more easily in the future with Delphi VCL Applications.
