Area Control, Introduction
Area Control, Introduction
The commands and functions of the theme "WR Area Control" allow you to control the display and the operation of your 4D Write areas.
You can control the screen updates by using the WR SCROLL TO SELECTION, WR UPDATE MODE and WR REDRAW commands.
The WR ON COMMAND and WR Get on command method commands allow you to control the behavior of the menu items of your areas.
You can retrieve menu status info (WR GET COMMAND INFO), as well as activate or lock menu items (WR EXECUTE COMMAND, WR LOCK COMMAND).
Also, the WR SET DOC PROPERTY and WR Get doc property commands provide you with information and control options on interface objects in your 4D Write areas.
A 4D Write area included in a form and associated with a 4D field is loaded before the control events of the form such as On Load. If the area contains references, it is necessary to recalculate them using the WR REDRAW command.
