OpenAsynchronous (Function)

In french: OuvreAsynchrone

Opens a window whose result will be retrieved via a WLanguage procedure ("callback").

Example

// Ouverture asynchrone sans passage de paramètres 
OpenAsynchronous(FEN_FenChoixDate, (), onFermeChoixDate)
INTERNAL PROCEDURE onFermeChoixDate(DateChoisie)
	SAI_DATE = DateChoisie
END

// Ouverture asynchrone sans passage de paramètres et lambda
OpenAsynchronous(FEN_FenChoixDate, (), (DateChoisie) => {SAI_DATE = DateChoisie})

// Ouverture asynchrone avec 2 paramètres
OpenAsynchronous(FEN_FenChoixDate, (DateSys(), "Sélectionner une date"), onFermeChoixDate)
INTERNAL PROCEDURE onFermeChoixDate(DateChoisie)
	SAI_DATE = DateChoisie
END

Syntax

OpenAsynchronous(<Window> [, <Parameters>] [, <Optional WLanguage procedure>])

<Window>: Window name

Name of the window to be opened.

<Parameters>: Optional character string

List of parameters to be passed to the window. This list of parameters has the following format:
(<Parameter 1>, ..., <Parameter N>)

where:
<Paramètre 1> First parameter to be passed to the "Global declarations" event of the window to be opened.. 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).
<Paramètre N> Nth parameter to be passed to the "Global declarations" event of the window to be opened. 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).

<Optional WLanguage procedure>: Optional procedure name 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 OpenAsynchronous.
This WLanguage procedure can correspond to:
a name of a global procedure,
a name of an internal procedure,
a lambda procedure.

Remarks

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 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.
