<Table>.RefreshVisible (Function)

In french: <Table>.RafraîchissementVisible

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:

Open the Table control description window.
On the "Details" tab, in the "Moves and gestures" area, check "Pull to refresh".
Validate.

This function is available in WINDEV only in order to be used in simulator mode. Used in a WINDEV application, this function has no effect.

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(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
TABLE_Données.RafraîchissementVisible(False)
END

False to hide it.

Getting the state of the 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 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.
<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 freezing (the example uses this method).
When <Table>.RefreshVisible 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, <Table>.RefreshVisible(False) must be called as many times as <Table>.RefreshVisible(True) was run.
