Stored procedures
Opens a window whose result will be retrieved via a WLanguage procedure ("callback").
Example
// Open asynchronously without passing parameters
WIN_DateSelect.OpenAsynchronous((),CloseDateSelect)
INTERNAL PROCÉDURE CloseDateSelect(SelectedDate)
EDT_DATE = SelectedDate
END
// Open asynchronously without passing parameters and lambda
WIN_DateSelect.OpenAsynchronous((), (SelectedDate) => {EDT_DATE = SelectedDate})
// Open asynchronously with 2 parameters
WIN_DateSelect.OpenAsynchronous((DateSys(), "Select a date"), CloseDateSelect)
INTERNAL PROCÉDURE CloseDateSelect(SelectedDate)
EDT_DATE = SelectedDate
END
Syntax
<Window>.OpenAsynchronous(<Parameters> , <WLanguage procedure>)
<Window>: Window name
Name of the window to be opened.
<Parameters>: Character string
List of parameters to be passed to the window. This list of parameters has the following format:
(<Paramètre 1>, ..., <Paramètre N>)

where:
  • <Parameter 1>: First parameter that will be passed to the "Global declarations" event of the window to open. This parameter is passed by value and is considered a variable global to the window.
    This parameter cannot be a variable of type array (arrays can only be passed by reference).
  • <Parameter N>: Nth parameter that must be passed to the "Global declarations" event of the window to open. This parameter is passed by value and is considered a variable global to the window.
    This parameter cannot be a variable of type array (arrays can only be passed by reference).
<WLanguage procedure>: Name of the procedure or lambda procedure
Name of the WLanguage procedure ("callback") called after the window is closed. For more details on this procedure, see Parameters of the procedure used by <Window>.OpenAsynchronous.
This WLanguage procedure can correspond to:
  • a name of a global procedure,
  • a name of an internal procedure,
  • a lambda procedure.
Remarks
  • <Window>.OpenAsynchronous opens the window in modal and asynchronous mode:
    • code execution continues without waiting for the window to be closed,
    • the WLanguage procedure will be called when the window is closed.
    • the user cannot click the parent window of the calling window.
  • A window opened with <Window>.OpenAsynchronous will be automatically closed if the calling window is closed. However, the "Close a child window" event of the calling window will not be executed.
Component: wd280obj.dll
Minimum version required
  • Version 27
