Modifies or returns the visibility status of refresh bar in a Table or TreeView Table control.
This function can be used when the Table control supports the "Pull-to-refresh" option. To enable this option in a Table control:
  1. Open the Table control description window.
  2. On the "Details" tab, in the "Moves and gestures" area, check "Pull to refresh".
  3. Validate.
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
ThreadExecute("threadMajTable", threadNormal, ProcThreadMajTable)
//----------------------------------------------------
// Procédure de mise à jour des données du champ Table
PROCEDURE 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 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
Syntax

Changing the state of the refresh bar Hide the details

TableRefreshVisible(<Table control> , <Visible>)
<Table control>: Control name
Name of the control to be used. This field may correspond to:
  • a Table control.
  • a TreeView Table control.
<Visible>: Boolean
  • True to display the refresh bar,
  • False to hide it.

Getting the state of the 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 field may 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 freezing (the example uses this method).
  • When TableRefreshVisible makes the refresh bar visible, the "Pull to refresh" event of the Table control is not executed.
    Note: It is possible to force execution of this event by using the ExecuteProcess function with the constant trtPullToRefresh.
  • To hide the refresh bar, TableRefreshVisible(False) must be called as many times as TableRefreshVisible(True) was run.
