It doesn't know ANYTHING until you tell it.  A pushbutton actually does absolutely nothing except sit on a form and look pretty. :-) The pushbutton does have some events that the user can trigger.  The event probably used most often is the onClick event.  The problem is that even triggering an event does absolutely nothing unless the programmer has assigned an event handler (function or codeblock) to the event.  This is true whether one is using a standard pushbutton or a custom pushbutton. With a custom pushbutton there is a possibility that in the .cc file event handlers have been assigned to events.  If no event handler has been assigned in the .cc file to an event you want to use then simply assign you own event handler exactly as you would with a standard pushbutton. If an event handler has been assigned to an event in the .cc file you have two choices.  You can completely bypass the event handler in the .cc file by assigning your own event handler as with a standard pushbutton.  Alternatively you can set up your own event handler with additional code and execute the event handler in the .cc file. Depending on the actual code you may need to execute the event handler in the .cc file before or after you execute your own code.     function cust_but1_onClick        cust_but_classname::onclick()         //additional code        return or     function cust_but1_onClick         //additional code        return cust_but_classname::onclick() Mervyn.
