WA GET PREFERENCE and WA SET PREFERENCE
Originally introduced in 4D v14 R2
For security reasons, changing a Web area contents by dropping a file or a URL in the area is disallowed by default starting with 4D v15. The mouse cursor now displays a forbidden icon 
when the user tries to drop a file or a URL in the area.
In previous releases, it was necessary to install a specific filter, using WA SET URL FILTERS for example, to prevent such actions.
If you want to allow this feature in 4D applications, you now need to set a new Web area preference: wa enable url drop.
A new preference is available in the selector parameter for the WA SET PREFERENCE command to enable a URL or file drop in the Web Area:
| Constant | Type | Value | Comment |
| WA enable URL drop | Longint | 101 | Allow the drop of a URL or file in the Web area (default = False) |
If you want to enable a URL drop in the Web area, this preference must be set before loading a URL, preferably during the On load form event.
To enable URL drops in the 'myarea' Web area:
WA SET PREFERENCE(*;"myarea";WA enable URL drop;True)
