I have been playing with the calendar sample code posted in the Share Your Code section. I was wondering if anyone had figured out how to add an event to a specific day or select a specific day? I am sure it is simple, but I just cant seem to figure it out. Here is the code:
local widget = require( “widget” )
local storyboard = require( “storyboard” )
local scene = storyboard.newScene()
– Our scene
function scene:createScene( event )
local group = self.view
local date = os.date( “*t” )
local curMonth = date.month
local curYear = date.year
– Creates a background
local function create_bg()
local background = display.newImage( “assets/background.png”, true )
group:insert( background )
end
--Returns name of month[i]
local get_month_name =
{
“January”, “February”, “March”, “April”, “May”, “June”, “July”, “August”, “September”, “October”, “November”, “December”
}
--Returns short name of month[i]
local get_short_month_name =
{
“jan”, “feb”, “mar”, “apr”, “may”, “jun”, “jul”, “aug”, “sep”, “oct”, “nov”, “dec”
}
--Returns days in a month, including for leap year
local function get_days_in_month(month, year)
local days_in_month = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 }
local d = days_in_month[month]
--Check for leap year
if (month == 2) then
if year%4==0 and (year%100~=0 or year%400==0) then
d = 29
end
end
return d
end
--Returns day of week
local get_day_of_week =
{
“sun”, “mon”, “tue”, “wed”, “thu”, “fri”, “sat”
}
--Get the first day of the month
local function get_start_day( cur_month, cur_year )
local temp = os.time{year = cur_year, month=cur_month, day=1}
return tonumber(os.date("%w", temp))
end
--Get the last day of the month
local function get_end_day( cur_month, cur_year )
return tonumber(get_days_in_month(cur_month, curYear))
end
– Creates the calendar
local function create_calender( year, month )
--Create previous month
local prevMonth = month - 1
local prevYear = year
if prevMonth < 1 then
prevMonth = 12
prevYear = prevYear - 1
end
local prevDays = false
local prevStartDay
local prevEndDay
--Create selected month
local selMonth = month
local selYear = year
local selDays = false
local selStartDay = get_start_day( month, year ) + 1 --Adds 1 because table index starts at 1.
local selEndDay = get_end_day( month, year )
--Create next month
local nextMonth = month + 1
local nextYear = year
if nextMonth == 13 then
nextMonth = 1
nextYear = nextYear + 1
end
local nextDays = false
local nextStartDay = 1
local nextEndDay
--Check if there is a previous month on the screen
local daysToSelMonth = 1 - selStartDay
if daysToSelMonth < 0 then
prevDays = true
end
if prevDays then
daysToSelMonth = daysToSelMonth + 1
prevEndDay = get_days_in_month( prevMonth, year )
prevStartDay = prevEndDay + daysToSelMonth
end
--Creates a “calender box” which shows selected month, year and the weekdays.
