Filters


This is what the Filters tab of
			the preferences dialog looks like.

This tab allows you to define various filters which should be applied before showing the headlines in the scroll text.

Note

These filters only affect the headlines which are shown in the scrolltext; the menu will always show all of the headlines.

The major part of the tab is occupied by a table which lists the currently configured filters. Each filter has a small checkable box - checking that box enables the filter, unchecking it temporarily disables it without removing it from the list.

By default there are no filters, so chances are that the table is completely empty for you. Of course, this dialog provides you with ways to add new filters, and manage them in general:

Filter Components

Each filter consists of four components:

Filter Components

  1. Action – this can be either Show or Hide and defines what should happen to a headline in case this filter matches.

  2. News sources – here you can define whether the filter affects only single news sources, or whether this filter should be applied to the headlines of all news sources.

  3. Condition – this is a verb which defines, together with the Expression, whether a filter matches. A condition can be for example, contains, doesn't equal or matches. See below for a more detailed description.

  4. Expression - this is a user-defined string which forms the body of the filter, together with the Condition. See below for a more detailed description of this component.

All these components can be configured using the facilities in the frame labeled Filter properties. The possible states of the Condition component deserve a special explanation:

  • contains, doesn't contain: this filter matches if the headline contains / doesn't contain the specified expression.

    Note

    The expression isn't treated case-sensitively, so the expressions “KDE”, “kDE” or “kde” will all match headlines which contain “KDE”.

  • equals, doesn't equal: this filter matches if the headline equals / doesn't equal the specified expression.

    Note

    The expression is treated case-sensitively, so of the expressions “Linux®”, “linux” or “LINUX”, only the first will match “Linux®”.

  • matches: using this condition will make KNewsTicker treat the given expression as a “regular expression”. For further information on regular expressions you might want to read this article which was published at www.evolt.org.
