DatePicker Display Dialog {( left ; top {; defaultDate})} -> Function result

Parameter	Type	Description
left	Longint	Location for left side of window
top	Longint	Location for top of window
defaultDate	Date	Date to select by default in the dialog
Function result	Date	Date selected by user

Description

The DatePicker Display Dialog command opens a DatePicker calendar in a pop-up window (a pop-up type window is automatically closed when the user clicks outside the window or hits the Enter or Esc key).

The two optional left and top parameters are used to specify the location of the top left corner of the window to be opened. These two parameters must be passed together; if only one is passed, it is ignored. If these parameters are omitted, the window is opened at the location of the click.

You can pass a defaultDate date as third parameter in order to set the DatePicker dialog have an associated date pre-selected when displayed to the user.

DatePicker Display Dialog returns the date selected by the user in the DatePicker calendar. If the window is closed without a date being selected by the user, the command returns a blank date (!00/00/00!), even if a defaultDate date was passed.

Example

This example displays a DatePicker calendar when a button is clicked:

 OBJECT GET COORDINATES(*;"MyCalendarButton";$x1;$y1;$x2;$y2)

 $MyLocalDate:=DatePicker Display Dialog($x1;$y1)

 If($MyLocalDate #!00/00/00!)

    [Event]DateRV:=$MyLocalDate

 End if
