/**
|
|
* @brief Abstract class to implement item effects for a Dolphin view.
|
|
*
|
|
* Derived classes must implement the following pure virtual methods:
|
|
* - ItemEffectsManager::setContextPixmap()
|
|
* - ItemEffectsManager::contextPixmap()
|
|
* - ItemEffectsManager::firstContext()
|
|
* - ItemEffectsManager::nextContext()
|
|
* - ItemEffectsManager::contextFileInfo()
|
|
*
|
|
* The item effects manager highlights currently active items and also
|
|
* respects cutted items. A 'context' is defined as abstract data type,
|
|
* which usually is represented by a KFileListViewItem or
|
|
* a KFileIconViewItem.
|
|
*
|
|
* In TQt4 the item effects manager should get integrated as part of Interview
|
|
* and hence no abstract context handling should be necessary anymore. The main
|
|
* purpose of the current interface is to prevent code duplication as there is
|
|
* no common model shared by TQListView and TQIconView of TQt3.
