Remarks

When using an infinite Table control, an internal loading window (containing a Progress Bar control) is displayed above the rows of the Table control while additional data is being added. This loading window is hidden at the end of the "Add additional elements" event.
<Table>.AddInProgress is used for example to check the display of the loading window 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>.AddInProgress makes the loading window visible, the "Adding additional elements" event of the Table control is not run.
To hide the refresh bar, the following code must be called
<Table control>.AddInProgress(False)
as many times as the code
<Table control>.AddInProgress(True)
was run.
