end

Instance Method Details

- (Object) filter=(value)

Changes the regexp used to filter the files, then re-applies the filter calling the invalidate method. =Arguments value:: the new regexp. It can be nil or a regexp. In the first case, the filter won’t be applied. =TODO On Windows, allow to also use the ‘\’ character as pattern separator. The problem is that that character is also the escape character in a regexp, so things may become complicated.

def filter= value
  @filter = value
  # TODO This doesn't work
  #on windows, where one can also use \ as separator. The problem is that in regexp
  #it's the escape character, so one must use something like
  #value.include?(File::SEPARATOR) || (File::ALT_SEPARATOR and value.match(/\\{2}))
  @role = if @filter and !value.source.include?(File::SEPARATOR) then Qt::UserRole + 1 
  else Qt::DisplayRole
  end
  invalidate
end

- (Object) filterAcceptsRow(r, parent) (protected)

Reimplementation of Qt::SortFilterProxyModel#filterAcceptsRow which returns true if the file matches the regexp and false otherwise (if the regexp is nil, this method always returns true).

If the source of the regexp contains the pattern separator, the whole filename is tested, otherwise only the name of the file will be tested.
