CHAPTER 5

Stationery

Using Stationery 5-13

Set the slots of the newtLabelNumInputLine as follows:

■ Set the label slot to "How Much".

■ Set the path slot to [pathExpr: kDataSymbol, 'howMuch]. This path

slot must evaluate to a slot in your data entry frame that contains a number (or a

place to store one).

Add a

newtLabelDateInputLine at the top of the default template so that it

is aligned as shown. Then set the slots as follows:

■ Set the label slot to "Date Due".

■ Set the path slot to [pathExpr: kDataSymbol, 'dueDate]. This path

slot must evaluate to a slot in your data entry frame that contains a date (or a

place to store one).

Add a

newtLabelTimeInputLine at the top of the default template so that it

is aligned as shown. Then set the slots as follows:

■ Set the label slot to "Due Time".

■ Set the path slot to [pathExpr: kDataSymbol, 'dueDate]. This path

must evaluate to a slot in your data entry frame that contains a time (or a place

to store one).

Registering Stationery for an Auto Part 5

When your stationery is implemented in an auto part, you are responsible for

registering and removing it. The following code samples show

InstallScript

and RemoveScript functions that use the appropriate global functions to register

and unregister the viewDef and dataDef ﬁles in your auto part as it is installed and

removed, respectively. Note that the print format ﬁle is also registered as a viewDef

with the system.

InstallScript: func(partFrame,removeFrame)

begin

RegDataDef(kDataSymbol, GetLayout("iouDataDef"));

RegisterViewDef(GetLayout("iouDefaultViewDef"),

kDataSymbol);

RegisterViewDef(GetLayout("iouPrintFormat"),

kDataSymbol);

end;

RemoveScript: func(removeFrame)

begin

UnRegisterViewDef('default, kDataSymbol);

UnRegisterViewDef('iouPrintFormat, kDataSymbol);

UnRegDataDef(kDataSymbol);

end;
