Par2: User control of locator types 2009-04-03 -- Dennis Evans If you mean can a locator on the screen change from an entry locator to
an incremental or maybe a filter locator and then to step locator then the
answer would be yes. I assume that you are looking to use only two types,
i.e. entry and incremental or incremental and filtered.
In a nutshell, all the locator classes are derived from a base locator
class, starting with the step, then entry, then incremental and finally
filtered. So if you want an entry, incremental combination on a screen
add the incremental, since it is derived from the entry, then when the user
wants an entry you would change the way the key strokes are handled. add
some code to the take Key method of the incremental before the parent call,
if (condition = entry locator)
return parent.takeKey()
end
that will return 0 so the browse is not updated until the control is
accepted, but it will put the key press in the entry control.
Ghange the control type from string to an entry control when the user
changes the condition.
