Detailed Description

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.

A base class for views of the KDE file selector

Definition at line 147 of file kfileview.cpp.

Reimplemented in KCombiView.

Definition at line 402 of file kfileview.cpp.

void KFileView::setOnlyDoubleClickSelectsFiles ( bool  enable  )  [inline]

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().

Definition at line 321 of file kfileview.h.

void KFileView::setParentView ( KFileView *  parent  )  [virtual]

Definition at line 90 of file kfileview.cpp.

virtual void KFileView::setSelected ( const KFileItem *  ,

This function must be implemented by the view.

Implemented in KCombiView, KFileDetailView, KFileIconView, and KFilePreview.

void KFileView::setSelectionMode ( KFile::SelectionMode  sm  )  [virtual]

Reimplemented in KCombiView, KFileDetailView, KFileIconView, and KFilePreview.

Definition at line 331 of file kfileview.cpp.

void KFileView::setSorting ( QDir::SortSpec  sort  )  [virtual]

Sets the sorting order of the view.

Default is QDir::Name | QDir::IgnoreCase | QDir::DirsFirst Override this in your subclass and sort accordingly (usually by setting the sorting-key for every item and telling QIconView or QListView to sort.

A view may choose to use a different sorting than QDir::Name, Time or Size. E.g. to sort by mimetype or any possible string. Set the sorting to QDir::Unsorted for that and do the rest internally.

KFileViewSignaler* KFileView::signaler (  )  const [inline]

Definition at line 347 of file kfileview.h.

QDir::SortSpec KFileView::sorting (  )  const [inline]

QString KFileView::sortingKey ( KIO::filesize_t  value,
bool  isDir,
int  sortSpec 
) [static]

An overloaded method that takes not a QString, but a number as sort criterion.

You can use this for file-sizes or dates/times for example. If you use a time_t, you need to cast that to KIO::filesize_t because of ambiguity problems.

Definition at line 389 of file kfileview.cpp.

QString KFileView::sortingKey ( const QString &  value,
bool  isDir,
int  sortSpec 
) [static]

This method calculates a QString from the given parameters, that is suitable for sorting with e.g.

QIconView or QListView. Their Item-classes usually have a setKey( const QString& ) method or a virtual method QString key() that is used for sorting.

Parameters:
value Any string that should be used as sort criterion
isDir Tells whether the key is computed for an item representing a directory (directories are usually sorted before files)
sortSpec An ORed combination of QDir::SortSpec flags. Currently, the values IgnoreCase, Reversed and DirsFirst are taken into account.

Definition at line 380 of file kfileview.cpp.

void KFileView::sortReversed (  ) 

Definition at line 164 of file kfileview.cpp.

bool KFileView::updateNumbers ( const KFileItem *  i  )

true if the item fits the view mode

Definition at line 110 of file kfileview.cpp.

void KFileView::updateView ( const KFileItem *   )  [virtual]

Definition at line 264 of file kfileview.cpp.

void KFileView::updateView ( bool  f = true  )  [virtual]

does a repaint of the view.

The default implementation calls

 widget()->repaint(f)
