Hi

I have a basic question for TCheckBox which has been irritating me for
many years.
For me it seems to be both onClick and onChanges are executed when
checked is changes by code.
onClick should only be run by a user click.

Test:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.CheckBox1Change(Sender: TObject);begin  CheckBox2.Checked :=
CheckBox1.Checked;end; procedure TForm1.Button1Click(Sender:
TObject);begin  CheckBox1.Checked := not
CheckBox1.Checked;end; procedure TForm1.CheckBox1Click(Sender:
TObject);begin  CheckBox3.Checked := CheckBox1.Checked;end;         
Or have I overlooked something?

Hi!

The common sense says: you are right!

But that does not matter:
This behaviour is Delphi compatible.
