I am migrating a VCL application to FMX. I need to know the class of a control that has focus. The application works with various dynamically created frames with numerous input controls.
In VCL I use the VCL.Forms.TScreen.OnActiveControlChange as this is the one place to consistently capture the active control. This event is not available in FMX.Forms.TScreen. What would be an alternative approach in FMX?
