First of all you are using the wrong mail list. And this cause you have
less answerts you could get.
Regards your question I suggest to look at TEditButton component - it
consists of TEdit and TButton (with image). I don't see what do you mean
by directly but there are somw ways to implement your task.
First - is to use TEdit and TButton internally. Second to use
TCustomControl and implement drawing, mouse, keyboard handling yourself.
The third way is to write your control using windows handles instead of
TEdit and TButton directly (not desired way since it is not
cross-platform). Everything is similar to how you would do thin in Delphi.
