FMX is the equivalent of making a small operating system on the interface itself.

FMX self-painting interface I also do not look good, such as copy and paste, too ugly, the system has done a very fine copy paste interface, is unable to recall, such as MIUI, copy and paste can have a magnifying glass, you can choose to the edge of the screen text, you can choose a plurality of pasted text in the Clipboard; and that memo, Sometimes the line is not broken, and some of the text can not be seen. Text input box, hide the Clipboard, and then click on it will not play, the system itself text box does not have this problem. The input box at the bottom of the input automatically move the interface, as if the operating system itself has it, FMX also have to make a lot of code, it is not necessarily compiled well. It's another thing to code a bug yourself.
FMX gave me the feeling that I made a small operating system on the interface, and that the benefits of the operating system on the phone itself were discarded.
The only benefit of FMX is a set of code across platforms, dedicated to lazy people.
