A base class for views of the KDE file selector
This class defines an interface to all file views. Its intent is to allow to switch the view of the files in the selector very easily. It defines some pure virtual functions, that must be implemented to make a file view working.
Since this class is not a widget, but it's meant to be added to other widgets, its most important function is widget. This should return a pointer to the implemented widget.
| KFileView ()
| KFileView |
| ~KFileView ()
| ~KFileView |
[virtual]
Destructor
| void addItemList (const KFileViewItemList &list)
| addItemList |
[virtual]
inserts a list of items.
| void addItemList ( const KFileItemList& list )
| addItemList |
Inserts a list of items. Use this method <b>only</b> if you are sure that the list really contains KFileViewItems or items subclassing KFileViewItem. You can use KDirLister to create a KFileItemList with any item, subclassing KFileItem. E.g. KFileReader creates KFileViewItems
See also: KDirLister::createFileItem
| QWidget * widget ()
| widget |
[pure virtual]
a pure virtual function to get a QWidget, that can be added to other widgets. This function is needed to make it possible for derived classes to derive from other widgets.
| void setCurrentItem (const QString &filename, const KFileViewItem * entry = 0)
| setCurrentItem |
[virtual]
set the current item in the view.
the normal use of this function is to use the parameter filename to set the highlight on this file.
the extend use of this function is to set filename to 0. In this case the KFileViewItem is used to find out the position of the file. Since this is faster, this way is used in case a view has other child views.
| void clear ()
| clear |
[virtual]
clears the view and all item lists
| void updateView (bool f = true)
| updateView |
[virtual]
does a repaint of the view.
The default implementation calls
widget()->repaint(f)</pre> |
| void updateView (const KFileViewItem*)
| updateView |
[virtual]
| void removeItem (const KFileViewItem *item)
| removeItem |
[virtual]
Remove an item from the list; has to be implemented by the view. Call KFileView::removeItem( item ) after removing it.
| QDir::SortSpec sorting ()
| sorting |
[const]
specifies the sorting of the internal list. Newly added files are added through this sorting.
| void setSorting (QDir::SortSpec sort)
| setSorting |
[virtual]
set the sorting of the view
Default is QDir::Name | QDir::IgnoreCase | QDir::DirsFirst Don't use QDir::Reversed, use sortReversed() if you want to reverse the sort order. Calling this method keeps the reversed-setting If your view wants to get notified about sorting-changes (e.g. to show a sorting indicator), override this method and call this implementation in the beginning of your method.
See also: setSortMode
| void setSortMode (KFile::SortMode mode)
| setSortMode |
set the sorting mode. Default mode is Increasing. Affects only newly added items.
See also: setSorting
| KFile::SortMode sortMode ()
| sortMode |
[const]
Returns: the current sort mode
See also: setSortMode, setSorting
| void sortReversed ()
| sortReversed |
[virtual]
Toggles the current sort order, i.e. the order is reversed.
See also: isReversed
| bool isReversed ()
| isReversed |
[const]
Tells whether the current items are in reversed order (= contrary to sortMode).
| uint count ()
| count |
[const]
Returns: the number of dirs and files
| uint numFiles ()
| numFiles |
[const]
Returns: the number of files.
| uint numDirs ()
| numDirs |
[const]
Returns: the number of directories
| void setSelectionMode ( KFile::SelectionMode sm )
| setSelectionMode |
[virtual]
| KFile::SelectionMode selectionMode ()
| selectionMode |
[const virtual]
| enum ViewMode {Files = 1, Directories = 2, All = Files | Directories } | ViewMode |
| void setViewMode ( ViewMode vm )
| setViewMode |
[virtual]
| ViewMode viewMode ()
| viewMode |
[const virtual]
| QString viewName ()
| viewName |
Returns: the localized name of the view, which could be displayed somewhere, e.g. in a menu, where the user can choose between views.
See also: setViewName
| void setViewName ( const QString& name )
| setViewName |
Sets the name of the view, which could be displayed somewhere. E.g. "Image Preview".
| void setOperator (QObject *ops)
| setOperator |
[virtual]
| void insertItem ( KFileViewItem *i)
| insertItem |
[pure virtual]
The derived view must implement this function to add the file in the widget.
| void clearView ()
| clearView |
[pure virtual]
pure virtual function, that should be implemented to clear the view. At this moment the list is already empty
| void ensureItemVisible ( const KFileViewItem *i )
| ensureItemVisible |
[pure virtual]
pure virtual function, that should be implemented to make item i visible, i.e. by scrolling the view appropriately.
| void clearSelection ()
| clearSelection |
[pure virtual]
Clear any selection, unhighlight everything. Must be implemented by the view.
| void selectAll ()
| selectAll |
[virtual]
Selects all items. You may want to override this, if you can implement it more efficiently than calling setSelected() with every item. This works only in Multiselection mode of course.
| void invertSelection ()
| invertSelection |
[virtual]
Inverts the current selection, i.e. selects all items, that were up to now not selected and deselects the other.
| void setSelected (const KFileViewItem *, bool enable)
| setSelected |
[pure virtual]
Tells the view that it should highlight the item. This function must be implemented by the view
| bool isSelected ( const KFileViewItem * )
| isSelected |
[const pure virtual]
Returns: whether the given item is currently selected. Must be implemented by the view.
| const KFileViewItemList * selectedItems ()
| selectedItems |
[const]
Returns: all currently highlighted items.
| const KFileViewItemList * items ()
| items |
[const]
Returns: all items currently available in the current sort-order
| void insertSorted (KFileViewItem *tfirst, uint counter)
| insertSorted |
[virtual]
Inserts "counter" KFileViewItems and sorts them conforming to the current sort-order. If you override this method, you have to call setFirstItem() afterwards, to set the first item of your newly sorted items.
| KFileViewItem * firstItem ()
| firstItem |
[const]
Returns: the first (depending on sort order) item. It forms sort of a list, as each item holds a pointer to the next item. This is only public for internal reasons, DON'T call it unless you implement a View yourself and really need to.
| void setOnlyDoubleClickSelectsFiles ( bool enable )
| setOnlyDoubleClickSelectsFiles |
This is a KFileDialog specific hack: we want to select directories with single click, but not files. But as a generic class, we have to be able to select files on single click as well.
This gives us the opportunity to do both.
Every view has to decide when to call select( item ) when a file was single-clicked, based on onlyDoubleClickSelectsFiles().
| bool onlyDoubleClickSelectsFiles ()
| onlyDoubleClickSelectsFiles |
[const]
Returns: whether files (not directories) should only be select()ed by double-clicks.
See also: setOnlyDoubleClickSelectsFiles
| bool updateNumbers (const KFileViewItem *i)
| updateNumbers |
increases the number of dirs and files.
Returns: true if the item fits the view mode
| void select ( const KFileViewItem *item )
| select |
[protected: ]
Call this method when an item is selected (depends on single click / double click configuration). Emits the appropriate signal.
| void highlight ( const KFileViewItem *item)
| highlight |
[protected: ]
emits the highlighted signal for item. Call this in your subclass, whenever the selection changes.
| int compareItems (const KFileViewItem *fi1, const KFileViewItem *fi2)
| compareItems |
[protected: const]
compares two items in the current context (sortMode and others) returns -1, if i1 is before i2 and 1, if the other case is true in case, both are equal (in current context), the behaviour is undefined!
| void QuickSort (KFileViewItem* a[], int lo0, int hi0)
| QuickSort |
[protected: const]
this is a help function for sorting, since I can't use the libc version (because I have a variable sort function)
| KFileViewItem * mergeLists (KFileViewItem *list1, KFileViewItem *list2)
| mergeLists |
[protected: ]
| void activateMenu ( const KFileViewItem *i )
| activateMenu |
[protected: ]
| KFileViewSignaler * sig | sig |
[protected: ]
| void setFirstItem ( KFileViewItem * item )
| setFirstItem |
[protected: ]
Call this method to set the first item after you call your own insertSorted(). You only need to call it when you override insertSorted().
| void resort ()
| resort |
[protected: ]
Call this if you changed the sort order and want to perform the actual sorting and show the new items.
