How to capture the active control in Firemonkey?

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?

Solution

  • The most similar approach in FMX would be to listen to the TForm.OnFocusChanged event. From within the event handler you could then look up theTForm.Focused property.
