Syntax
Modifying the visibility status of internal wait window Hide the details
<Looper control>.AddInProgress(<Visible>)
<Looper control>: Control name Name of the Looper control to be used. <Visible>: Boolean - True to display the internal wait window,
- False to hide it.
Retrieving the visibility status of internal wait window Hide the details
<Result> = <Looper control>.AddInProgress()
<Result>: Boolean - True if the internal wait window is displayed,
- False otherwise.
<Looper control>: Control name Name of the Looper control to be used. Remarks - When using an infinite Looper control, an internal wait window (containing a Progress Bar control) is displayed above the rows of the Looper control while additional data is being added. This wait window is hidden at the end of the "Adding additional elements" event.
- <Looper>.AddInProgress is used for example to check the display of wait window when the data found in the Looper control is refreshed in a secondary thread. This prevents the application from freezing (the example uses this method).
- When <Looper>.AddInProgress makes the wait window visible, the "Adding additional elements" event of the Looper control is not run.
- To hide the refresh bar, <Looper>.AddInProgress(False) must be called as many times as <Looper>.AddInProgress(True) was run.
