Delphi: Inheriting Parent Properties

The ability to inherit Parent properties is very convenient. Let's say you have a form with several controls on that form. If you wanted to change the default font from "Tahoma" to "Segoe UI" wouldn't it be nice to only have to make that change in one spot and voila, the change happens everywhere?

Well that is what inheriting the Parent properties is all about.

Unfortunately, not all the Parent properties get inherited. The font color is one of those properties that gets inherited by some controls but not all controls. I created this short video to show what happens to some of the most used VCL controls when you change the forms Font Color and Font Family.

So, be careful and don't assume that one single change to the forms properties will get propagated throughout your entire application.

Semper Fi,
