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
.
