[Lazarus] how to get Type of Sender or Components[i] in order to Cast?

[Péter Gábor]

Sorry!
I was "misreading" your mail... you want to know the type of them.

You can compare the type of them:

if Sender = TButton then { do something} ;

or you can get the name of the class

ShowMessage( Sender.classname );
