Hello Everyone,

I am having a problem disabling 4th dimension buttons.  Is there a
specific place that I have to disable the buttons (ie. Only in layout
procedure).  Currently, i am using a global procedure an saying "DISABLE
BUTTON(button)", pretty standard stuff huh.  However, my button will not
become disabled.  I am 
currently using 4th Dimension v2.2.1.


If anyone out there could help me I would greatly appreciate it.

     Thanks in advanced,


            Jason Herman

I've tried disabling buttons from the startup script (since I didn't
find a way to set the button disabled by default). That didn't work
however, it seems that the layout must be displayed before the buttons
can be disabled. I don't think it should matter what kind of procedure
is doing the disabling, but then, you never know with 4D...

A related question, I guess there is no way to disable a popup menu?

The earliest point available for disabling a button is during the 'before'
state of the layout execution cycle.  You can test for this using 'IF (BEFORE)'
of placing ':(BEFORE)' in a case of.  'BEFORE' is a function that returns
true during the before part of the execution cycle and false otherwise.

Example:

if (before)

  disable button (<button name>)

end if
