Example

// Traitement "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.
TABLE_Données.RafraîchissementVisible(Vrai)
// Exécute l'actualisation des données du champ Table dans un thread secondaire
ThreadExecute("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
PROCEDURE ProcMajTable(sDonnees est une chaîne)
// Traitement des données reçues pour remplissage du champ Table
...
// Les données du champ Table sont à jour, on masque le bandeau de rafraîchissement
TABLE_Données.RafraîchissementVisible(Faux)
FIN

Modifying the visibility status of refresh bar Hide the details

<Table control>.RefreshVisible(<Visible>)

False to hide it.

Finding out the visibility status of refresh bar Hide the details

<Result> = <Table control>.RefreshVisible()

<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.
<Table>.RefreshVisible 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 <Table>.RefreshVisible, 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 <Table>.RefreshVisible(False) as many times as <Table>.RefreshVisible(True) has been executed.
