Return the item ID of field at the cursor position (Screen class)


This callable function returns the numeric item ID of the ScreenField where the cursor is located. A ScreenField is assigned an item ID either when it is instantiated by the AddField method (“AddField” on page 894), or if it is specified with the Screenfield Itemid method.

Syntax

[%number =] screen:CursorItemId

Syntax terms

%num
A numeric variable to contain the returned item ID. If no item ID was assigned to the screenField, zero is returned.
%screen
A reference to an instance of a Screen object.
