' This program expands on the original AllGadgets program by making
'all the gadgets do something. This mainly entails connecting various
'gadgets so that they effect each other.
' For example, the listview gadget has been connected to the string gadget
'below it to allow you to change the entries in the listview, and the
'checkboxes now disable various other gadgets, but there are many other
'features, so have a play.
' This mainly demonstrates how easy it can be to set up an interesting
'program from a GadToolsBox framework. It also shows how to use the
'J Set Gadget Data command, along with the J Gadget Number/String commands
'(though for v39 upwards, it is more correct to use J Get Gadget Data).
' To help show how it was constructed, the changes made have been written
'below.
' Changes made:
'
' A handler has been added to interconnect the gadgets, this is in the
' wait loop. To do the actual processing, the _HANDLEGADGETS procedure has
' been added.
' The global variable _LISTSEL has been added to keep track of which item
' of the listview gadget has been selected.
' The size of the strings defined for the listview gadget in the _GUIDATA
' routine have been set to a standard length of 30. This is the same as the
' maximum string length for the attached string gadget. This allows us to
' edit the strings safely without the worry of writing out of the end of the
' string.
' The global variable MYASL has been added. Code for creating a file
' requester has been placed before the events loop, and a line to remove
' it in the cleanup routine
' The global variables DIS1-4 have been added to track which gadgets
' are disabled.
