Example

// Evénement "Rafraîchissement par tirer/Relâcher" du champ Table
// ---------------------------------------------------------
// Demande à contrôler l'affichage du bandeau de sélection car l'actualisation des
// données du champ Table va être effectuée dans un thread secondaire.
// Dans le cas contraire, le bandeau de rafraîchissement serait automatiquement masqué à la
// fin de l'exécution du traitement.
TableRefreshVisible(TABLE_Données, True)
// Exécute l'actualisation des données du champ Table dans un thread secondaire
ThreadExécute("threadMajTable", threadNormal, ProcThreadMajTable)

//----------------------------------------------------
// Procédure de mise à jour des données du champ Table
PROCÉDURE ProcThreadMajTable()
// Exécution d'une requête HTTP
HTTPRequest(...)
// Retourne dans le thread principal pour ajouter le contenu de la requête dans le champ Table
ExecuteMainThread(ProcMajTable, HTTPGetResult())
END

// ---------------------------------------------------
// Procédure de remplissage des données du champ Table
PROCÉDURE ProcMajTable(sDonnees is string)
// Traitement des données reçues pour remplissage du champ Table
...
// Les données du champ Table sont à jour, on masque le bandeau de rafraîchissement
TableRefreshVisible(TABLE_Données, False)
END

True to display the refresh bar,
False to hide it.

Finding out the visibility status of refresh bar Hide the details

<Result> = TableRefreshVisible(<Table control>)

<Result>: Boolean

True if the refresh bar is displayed,
False if the refresh bar is hidden.

<Table control>: Control name

Name of the control to be used. This control can correspond to:
a Table control.
a TreeView Table control.

Remarks

During a "Pull to refresh", the refresh bar corresponds to the area displayed above the rows of the Table control during the data refresh.
TableRefreshVisible is used for example to check the display of refresh bar when the data found in the Table control is refreshed in a secondary thread. This prevents the application from being locked (the example is using this method).
When the refresh bar is made visible by TableRefreshVisible, the event "Refreshing by pull/release" of the Table control is not run.
Remark: It is possible to force the execution of this event by using the ExecuteProcess function with the trtPullToRefreshconstant.
To hide the refresh banner, it is necessary to call TableRefreshVisible(False) as many times as TableRefreshVisible(True) has been executed.
