4 File Selector Use
Once a filter is set (such as a filename mask or a file attribute match/mismatch filter), you may wish to delete the filter. To remove a filter designated by a flag in an instance field, simply clear the flag with the appropriate message.
If the filter is applied via a variable data field, however, you will have to use
MSG_META_DELETE_VARDATA
. This message is detailed in
MetaClass
and must be passed the name of the variable data field to be removed. Removal of the field equates to removal of the filter.
