InfoWithTimeoutAsynchronous (Function)

In french: InfoAvecDélaiAsynchrone

Displays a custom message in a non-blocking system information window for a given amount of time. After the timeout, the system window is automatically closed.

Remarks:

This is a non-blocking error window. The WLanguage code that follows the call to InfoWithTimeoutAsynchronous continues to run. To close the window, the user must validate the OK button or wait for the end of the timeout. When the user clicks "OK", the code of a WLanguage procedure can be run.
In the WLanguage code following the call to the function, another modal window cannot be opened before closing the dialog box.
WINDEV allows you to apply the skin template of your project to this dialog box. For more details, see Customizing dialog boxes.

Example

// Affiche une fenêtre d'information avec fermeture automatique après 10 secondes
InfoWithTimeoutAsynchronous(1000, "L'opération a réussi !", MaProcédure_Info)

	INTERNAL PROCEDURE MaProcédure_Info()
		ToastDisplay("Fermeture de l'info")
	END

Syntax

InfoWithTimeoutAsynchronous(<Timeout> , <Text> [, <WLanguage procedure>])

the duration in a readable format (e.g., 1 s or 1000 ms).

<Text>: Character string

<WLanguage procedure>: Optional name of procedure or lambda procedure

Name of the WLanguage procedure ("callback") called when the user clicks "OK" in the information window.
This WLanguage procedure can correspond to:

If this parameter is not specified, no procedure is run when the user clicks "OK" in the information window.

InfoWithTimeoutAsynchronous(500, "La fiche XXX a été modifiée." + CR + "Cette fiche va être sauvegardée.")

You also have the ability to use the syntax of multiline strings. For example:

InfoWithTimeoutAsynchronous(
[
La fiche XXX a été modifiée. 

Cette fiche va être sauvegardée.
])
