// end of process execution.
TableRefreshVisible(TABLE_Data, True)
// Refreshes the data of Table control in a secondary thread
ThreadExecute("ThreadUpdTable", threadNormal, ProcThreadUpdTable)

//----------------------------------------------------
// Procedure used to update the data in the Table control
PROCEDURE ProcThreadTableUpdate()
// Run an HTTP request
HTTPRequest(...)
// Goes back to the main thread to add the request content into the Table control
ExecuteMainThread(ProcUpdTable, HTTPGetResult())
END

// ---------------------------------------------------
// Procedure for filling data in the Table control
PROCEDURE ProcUpdateTable(sData is string)

False to hide it.

Finding out the visibility status of refresh bar Hide the details

<Result> = TableRefreshVisible(<Table control>)

<Result>: Boolean

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.
Note: To force the execution of this event, use ExecuteProcess with the constant trtPullToRefresh.
To hide the refresh bar, TableRefreshVisible(False) must be called as many times as TableRefreshVisible(True) was run.
