Defined in:
lib/ruber/filtered_output_widget.rb

Overview

Filter model derived from Qt::SortFilterProxyModel which better integrate with FilteredOutputWidget.

The differences between this class and Qt::SortFilterProxyModel are the following

  • it has the ability to ignore the filter (see FilteredOutputWidget)

  • it provides an easy way to always accept some kind of items (see exclude and

exclude_from_filtering?)

  • it emits a signal when the filter reg exp is changed

Note: this class is meant to be used with a regexp filter, not with a string filter.

Signals

filter_changed(QString reg)

Signal emitted when the regexp used for filtering changes (including when the filter is removed). reg is a string containing the source of the regexp.
