Detailed Description
template<class IconItem, class Parent>
class KMimeTypeResolver< IconItem, Parent >
This class implements the "delayed-mimetype-determination" feature, for konqueror's directory views (and KFileDialog's :).
It determines the mimetypes of the icons in the background, but giving preferrence to the visible icons.
It is implemented as a template, so that it can work with both QPtrListViewItem and QIconViewItem, without requiring hacks such as void * or QPtrDict lookups.
Here's what the parent must implement :
- void mimeTypeDeterminationFinished();
- QScrollView * scrollWidget();
- void determineIcon( IconItem * item ), which should call KFileItem::determineMimeType on the fileItem, and update the icon, etc.
