Detailed Description

Allows filtering of text in a text edit. This will keep track of the 'original' text so that changes to the filter will be redone on that text. Example:

FilterTextEdit fte;
fte.setPlainText("This is a first line\nThis is a second line");

It now shows:

This is a first line
This is a second line

One can for example filter on the word 'first'

fte.setFilter("first");

It now shows:

This is a first line

If another filter is set the 'original' text is re-filtered:

fte.setFilter("second");

It now shows:

This is a second line
