Syntax

Modifying the visibility status of refresh bar Hide the details

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

Finding out the visibility status of 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 control to use. 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.
  • 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.
    Remark: It is possible to force the execution of this event by using function ExecuteProcess with the constant trtPullToRefresh.
  • To hide the refresh banner, it is necessary to call TableRefreshVisible(False) as many times as TableRefreshVisible(True) has been executed.
