Longint

Description
The command DR Last event returns the code of the last event that occurred in area.
DR Last event can be used in the object method of a 4D Draw area or in an event method installed with DR ON EVENT. DR Last event identifies the event that caused the object or project method to execute. When used with the DR EVENT FILTER command, DR Last event allows you to take action based on a user's actions. See Appendix C, Event Codes, for a complete list of event codes.
Example
The following example is the object method for a 4D Draw area. It first tests to see if the object method ran because of a Command-click (or Ctrl-click in Windows) and then tests to see if only one object is selected. If both criteria are met, it passes the object's reference number to a project method.
If (DR Last event (Area) = 64) `Was there a Command-Click If (DR Count (Area;0) = 1) `How many objects are selected PART INFO (DR GET ID(Area;0;1)) `Pass ref number to PART INFO. End if End if
The following is the PART INFO method. This method searches for the part, calls a project method that opens a centered window, and then displays the record for modification.
QUERY ([Parts];[Parts]ID=$1) `Search for record that goes with object CENTER WINDOW (400;300) `Open a centered window MODIFY RECORD ([Parts];*) `Allow the user to make modifications CLOSE WINDOW `Close the window
