CHAPTER 19

Built-in Applications and System Data

Dates 19-21

■ OpenMeetingSlip opens the meeting slip for a specific meeting or event.

■ RegInfoItem adds and UnRegInfoItem or deletes an item in the Info picker

in the base view of the Dates application. This example shows how to add a

command that displays the next day’s To Do List to the Info button:

GetRoot().calendar:RegInfoItem('|NextDayToDo:MyApp|,

{ item: "Next Day's To Do",

doAction: func()

begin

local cal := GetRoot().calendar;

cal:DisplayDate

(cal:GetSelectedDates() [0]

+(24*60),'ToDoList);

end;

});

Controlling the Dates Display 19

There are two system variables you can set to control speciﬁc features of the Dates

display:

firstDayOfWeek and useWeekNumber.

The Dates variable

firstDayOfWeek speciﬁes what the ﬁrst day of the week

should be, for display purposes. It holds an integer value from 0 to 6, where 0

means Sunday, 1 means Monday, and so on. The default value is 0, which means

that by default all months show Sunday as the ﬁrst day of the week.

Once this value has been set, all new views of the class

clMonthView and views

that display meeting frequency reﬂect the new value, but existing views must be

closed and reopened to reﬂect the new value. This variable is part of the

system-stored user conﬁguration data (the Dates application checks there ﬁrst), or

in the locale bundle frame (Dates checks there next).

The Dates variable

useWeekNumber controls display of a week number in the

upper-left corner of the Dates view. If this slot is non-

nil, the Dates application

displays the week number there. The ﬁrst week of the year is number 1 and the last

week is number 52. This variable is a slot in the locale bundle frame.

To get and set the value of user conﬁguration variables, use the functions

GetUserConfig and SetUserConfig; this frame and the two functions are

described in “System Data” (page 19-44). To return the current locale bundle

frame, use the global function

GetLocale.
