Show TEdit in FireMonkey has an error in it with red border
I'm working on a mobile application where the user needs to login.
The server is returning me if the e-mail is invalid, or subdomain or password and I want to focus the TEdit that has the error. Focus is easy but I would also like to mark the edit as invalid like many web applications do.
What is the best way to do this is a consistent way so it will look correct on both Android as iOS. Is something like this built-in? I'm using Delphi 10.1
Solution
Loki's suggestion is a possible solution.
A solution which takes advantage of FMX features would be to use a TGlowEffect for the red frame around the TEdit and then use a TPopup to create the hint.
