AfterFolderChangeData

If a script add-in implements the OnAfterFolderChange event, the method receives an AfterFolderChangeData object once the folder read is complete.

Property Name	Return Type	Description
action	string	Returns a string indicating the action that triggered the folder read. The string will be one of the following: normal, refresh, refreshsearch, refreshsub, parent, root, back, forward, dblclk. The refreshsub actions means the folder (and sub-folders) are being refreshed while Flat View is on. The other action names should be self-explanatory.
path	object:Path	If the read failed, this will return a Path object representing the path that Opus tried to read. If the read was successful, this property is not provided - instead, the tab property provides access to this information. Use the result property to know if the read was a success.
qualifiers	string	Returns a string indicating any qualifier keys that were held down by the user when the event was triggered. The string can contain any or all of the following: shift ctrl, alt, lwin, rwin If no qualifiers were down, the string will be: none
result	bool	Returns True if the folder was read successfully, or False on failure.
tab	object:Tab	Returns a Tab object representing the tab that read the folder.
