I want check in my editor if files changed outside.
One way is check file time and size in Application.OnActivate, this
work on Windows but not in Linux Mint CInnamon, better is
Application.OnRestore which is called after each restoring from
minimization, but not after go to application by Alt+Tab.

Hi!

Application.OnActivate is fired only once in Linux: The first time the
app is shown.

If you only want to check after restoring from minimized use
Form.OnResize.
There you can check if the form was minimized and then check your
files.

MInimization I check by Allication.OnRestore,
but is possible check after Alt+Tab without minimization?
Is OK if I click on other appication window and again on my editor,
but not detect Alt+tab.
Similar is get Application.Active in timer, after go out with Alt+tab,
in Cinnamon Application think that is active.

As I told you:

use Form.OnResize.
