Add-on to [arsd.minigui] to provide date and time widgets.
|
||||
|
||||
History:
|
||||
Added March 22, 2022 (dub v10.7)
|
||||
|
||||
Bugs:
|
||||
The Linux implementation is currently extremely minimal. The Windows implementation has more actual graphical functionality.

A CalendarPicker is a rectangular input for picking a date or a range of dates on a
|
||||
calendar viewer.
|
||||
|
||||
The current value is an [Interval] of dates. Please note that the interval is non-inclusive,
|
||||
that is, the end day is one day $(I after) the final date the user selected.
|
||||
|
||||
If the user only selected one date, start will be the selection and end is the day after.
|
||||
+/
|
||||
/+
|
||||
Note the Windows control also supports bolding dates, changing the max selection count,
|
||||
week numbers, and more.
