Method Detail

doit

public int doit()
         throws java.lang.Exception

Presents the user with the selected list of element files to delete from disk using SelectFilesPanel.showDialog(). Any files selected by the user are then removed from their containing folders and deleted from disk. Note that although the Action associated with this command is enabled (otherwise we should never get here), it has been enabled with a quick check version of canRemove() called on each selected element's folder. A more thorough version of canRemove() check is performed here prior to actually performing the remove().
