|
|
* This effect was written for a talk at Akademy 2010 to have the current
|
|
* score of the 2010 World Cup Quarterfinal Argentina vs Germany on screen
|
|
* during the presentation.
|
|
*
|
|
* The effect connects to the German football website "kicker.de" and parses
|
|
* the returned website. This explains the name of the effect - it is unrelated
|
|
* to the panel of KDE 3.
|
|
*
|
|
* The effect is a nice illustration on how to use EffectFrames and animations.
|
|
* Therefore it was imported into the test directory in SVN to provide a small
|
|
* example.
|
|
*
|
|
* The effect consists of two parts:
|
|
* displaying the current score and showing a goal animation when a goal is
|
|
* scored. The first uses a Plasma styled EffectFrame, while the latter uses
|
|
* an unstyled effect frame.
