-=======
-
-Here is the result of a long discussion between the kfile developers
-(Carsten) and the konqueror developers (Simon and David), about the plans
-for more integration between kfile and konqueror. 16/08/2000.

- KFileIconView KFileListView
- (4) (5)
-
-
-(1) Gives items found when listing, and the key for each item
- (KDirLister has all the sorting code)
-(2) KFileView inherited classes emit requests for listing a new
- directory (with a bool for treeviews), and emit requests for
- the mimetype of a given item. If all KFileView inherited classes
- are QScrollViews, then it could even implement the "ask for mimetype
- of the visible icons first" algorithm, currently in KonqIconView.
-(3) KFileView, the base class for any view, knows about KFileItem, has
- signals for dropped(), popupMenu(list of actions provided by the view),
- has a QWidget * canvas() method, xOffset() and yOffset()
-(4) KFileIconView holds a QPtrDict to look up a QIconViewItem quickly from a
- given KFileItem. This will help for e.g. deleteItems and refreshItems.
-(5) KFileListView holds a QPtrDict to find the QListViewItem for a
- KFileItem. It implements different modes if we want the tree view in
- kfile ?
-
-
- KFileChooserWidget
-
-This (base) class is the container widget that can contain any kfileview and
-switch between them. It is embeddable into an application that wants a widget
-for choosing a file or directory. Features listing, selecting, popupmenu for
-switching modes, and a virtual createView( viewmode ) method, which
-only knows about the builtin views, in this class.
-It knows the current URL, has setURL(), and triggers the listing, connecting
-KFileView's requests to KDirLister's methods.
-
- KFileManagerWidget
-
-This class inherits from KFileChooserWidget and adds the file management
-operations. It uses a KFileOperations class (taken from the current
-KonqOperations) for all KIO operations, and it uses KFileUndo, taken from
-the KonqUndo stuff. The popupMenu method is reimplemented to add those
-operations to it.
-
- KFileWidget
-
-This class is the full widget that can be seen in the dialog. It has the
-toolbar buttons, the combo, etc. It embeds a KFileChooserWidget or a
-KFileManagerWidget, the latter being a specialisation of the former.
-
-The Konqueror side of things
-============================
-
- KonqFileIconView
-
-Inherits KFileIconView and adds image preview - unless we want it in
-KFileIconView, and the line-up-icons algorithm, etc.
-
- KonqFileListView
-
-Inherits KFileListView to add more stuff if needed. The mc-like text view
-could be implemented here as well, unless we want it in kfile. Same for the
-tree view.
-
- KonqFileManagerWidget
-
-This class inherits KFileManagerWidget and adds the konqueror stuff, like
-the enableAction signal. It also reimplements createView to create the
-konqueror versions of the views.
-
- KonqDirPart
-
-This class inherits KParts::ReadOnlyPart, and provides a BrowserExtension.
-It integrates KonqFileManagerWidget as its KParts widget, and provides
-KActions for it.
-
-Important :
-
-Make sure to take kfind into account. It would be nice if it could use the
-same views as konqueror, to have access to all the view modes, as well as
-image preview, etc.
