Hello,

In my code I'm overriding "Form.ActiveChanged" to catch when control focus changes and perform some global checks, it works fine except when focus is changed with mouse.

As a test I've added a handler in Screen.ActiveControlChanged and in this case it works with both mouse and keyboard.

Is this behaviour intented ? I'm testing in Windows 7 with SVN fpc and Lazarus. I do not know how Delphi works.

Attached there is a small test program, change the TEdit focus using both mouse and keyboard (Tab) and see the differences.

Saludos,
José Mejuto

In D7 TForm.ActiveChanged is not fired if I change the focus with the mouse, but it is if I change focus with Tab.

Hello,

Thank you, so it is Delphi compatible and nothing to be changed. Thank you for your tests.

Hello,

Just for the record I get the same effect as Screen if I override:

function SetFocusedControl(Control: TWinControl): Boolean; override;
