TObject |
A descendant of the FPC TComponent class. It adds a location where we can extend the TComponent, without having to make changes to each and every class in fpGUI.
For example: We added the TagPointer property (which is now largely obsolete) because a while back the Tag property of TComponent could only store a 32bit value. Many developers used it to store a pointer reference to a object under 32-bit system, but this was not possible under 64-bit systems. After some time, FPC finally updated the type of the Tag property to support 64-bit addresses too.
