Hi John,
I don't know about elegant, and it's been a while since I last did
something like this, but I used to have a variable in the form class
called bSystem (boolean, of course).
In the OnExit event I check if this is true, and then just return if it is.
Then anywhere that I don't want the event to "execute", I just set
bSystem to true before I do anything else.
Remember to reset it to false again afterwards though! ;)
Regards,
Bevan

On an edit box (TEdit), in the exit event I often will have some
verification code for any alteration made to the text.
However sometimes I don't want it to fire, for example if elsewhere on the
form is an unrelated button eg "Setup Options" and the user clicks there in
this case I just want focus to go to the other control, without firing the
exit event. (I don't mind losing the contents or the checking of the Tedit
in this case, as the user has elected to do something unrelated). However
the exit event on the Tedit fires before any event code on the Tbutton
(Setup Options) fires.
It seems to me to require code in the Tedit exit event checking how the exit
has been fired...whether by Tab key, or by clicking elsewhere. But this
gets quite tedious if there is a screen of Tedits. And it has to be smart -
if the user has just clicked on the next Tedit field, in that case I would
want the exit event on the previous one to still fire.
How do others do this - is there an elegant way?
John
