isCOBOL Evolve : User Interface : Controls Reference : ENTRY-FIELD : Properties : Notify-Change-Delay
Notify-Change-Delay
This property specifies how many milliseconds the runtime has to wait before firing a NTF-CHANGED event when the user changes the content of the Entry-Field. In this way it’s possible to catch multiple changes in a single NTF-CHANGED event, increasing performance.
By default, the delay specified by the iscobol.gui.entryfield.notify_change_delay * configuration property is used. If iscobol.gui.entryfield.notify_change_delay * is not set or is set to 0, then an NTF-CHANGED event is fired for each single change made by the user.
 
Example - Define an entry-field control with a delay of half second for change notifications
