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.
