How to force an ONEXIT Event from an Edit Box?

[Dan]

Overview: The user enters a date into an regular edit box. If the user
uses the TAB key, the OnExit event fires for the Edit Box (good). If the
user CLICKS the DEFAULT button, the OnExit event fires. However, if the
user hits the ENTER key, the Default button ONCLICK fires without the OnExit
firing first.

I do my validation routine with the Edit Box OnExit event - which works in
every case EXCEPT when the user hits ENTER and fires off the default button.

So, how can I make the OnExit event fire in the case that the user simply
presses ENTER?

Thank you!

Hi Dan,

in the onClick event of the button do a TButton(Sender).SetFocus.
That will move the focus to the default button and trigger the onExit of
the last component.

Because input focus is moving away from the TEdit to the next control in the
tab order.

Because input focus is moving away from the TEdit to the TButton.

Because input focus is NOT moving away from the TEdit. The TButton is not
being focused. Pressing ENTER simply calls the OnClick event handler
directly without any window messages involved on the button.

OnExit is not really a good place for that, especially when input focus is
concerned. if Windows is in the process of moving focus to another control,
and you try to force it back to the TEdit, Windows can freak out and weird
behaviors can occur.

You could have the TButton's OnClick handler check if the form's
ActiveControl is still pointing to the TEdit, and if so then perform the
validation.
