Hi all.
I have a group that contains a number of objects, buttons, menus,
fuelds and groups. I just noticed that if I disable a group (so that
none of the objects in the group can be interacted with) I get the
desired effect. However when re-enabling the group, it *ALSO*
re-enables ALL the objects in that group, no matter what their status
was prior to disabling the group.
Is that the expected behavior? If not I will file a bug report. If so,
I will have to find another way to disable all the objects in a group,
or else trap for the action, and save the enabled property for every
containing object so I can reset them.
It has been like that forever - there is an anomaly for it:
https://quality.livecode.com/show_bug.cgi?id=14881
The 'disabled' property should be effectively computed as the logical
and of all the parent's property values (kind of like inherited
properties, but with a different operation merging parent and child
values), a bit like visible is - why it was never done that way
originally is a question to which I do not have an answer!
The problem with 'just' fixing it is that it is not possible to
determine with the current behavior what the 'disabled' setting of any
control is meant to be. If it is changed, then all controls in disabled
groups which exist now will remain disabled - everyone would have to go
through all their stacks and set the enablement of children
appropriately.
Warmest Regards,
Mark.
