Get Specific Day Of Week From Popup Calendar

I need to capture the Sunday of a particular week selected with the Popup Calendar object and can’t find a script function to subtract days from the selected day. Basically, if a user clicks on Wednesday, February 11, 2015, I need to capture Sunday, February 8, 2015.

You can use java.util.Calendar to get the day of week:

Here’s a window to play with. Take note of the propertyChange script and custom properties of the calendar component. :slight_smile:

StartOfWeek_2015-02-11_1005.proj (9.74 KB)

EDIT: Sorry for the way short answer. I got pressed for time and I wanted to have something ready for you. :laughing:

The propertyChange script grabs the date, sets it to a java.util.Calendar object, and extracts the day of week. It then pops the result back out to the DOW custom property (minus 1-- more on that in a bit…).

if event.propertyName=='date': from java.util import Calendar d=event.source.latchedDate c=Calendar.getInstance() c.setTime(d) event.source.DOW=c.get(Calendar.DAY_OF_WEEK)-1
The StartOfWeek custom property uses the expression:

dateArithmetic({Root}, -({Root Container.Calendar.DOW}), "day")
Now, to explain the ‘minus 1’ thing. In the java.util.Calendar, Sunday has a value of one. If we left it that way it was, would actually be taking away one more day than needed. So we subtract on up front to give us a true offset to the day of week.

Thanks Jordan. I did go back and add a custom property and used an expression to capture it.

switch({Root Container.Popup Calendar.DaySelected}, "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", dateArithmetic({Root Container.Popup},-1,"day"), dateArithmetic({Root Container.Popup},-2,"day"), dateArithmetic({Root Container.Popup},-3,"day"), dateArithmetic({Root Container.Popup},-4,"day"), dateArithmetic({Root Container.Popup},-5,"day"), dateArithmetic({Root Container.Popup},-6,"day"), {Root Container.Popup})

DaySelected is another custom property that is the day of week:

dateFormat({Root Container.Popup},"E")
