Detailed Description

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.

[virtual]

Start the mimetype-determination. Call this when the listing is completed.

Parameters:

delayNonVisibleIcons

the delay to use between icons not on screen. Usually 10, but should be set to 0 when the image preview feature is activated, because image preview can only start once we know the mimetypes
