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

pure virtual function, that should be implemented to make item i visible, i.e.

by scrolling the view appropriately.

Implemented in KCombiView, KFileDetailView, KFileIconView, and KFilePreview.

◆ insertItem()

void KFileView::insertItem ( KFileItem * i )

virtual

The derived view must implement this function to add the file in the widget.

Make sure to call this implementation, i.e. KFileView::insertItem( i );

Reimplemented in KFilePreview, KCombiView, KFileDetailView, and KFileIconView.

Definition at line 147 of file tdefileview.cpp.

Definition at line 329 of file tdefileview.h.

◆ readConfig()

void KFileView::readConfig	(	TDEConfig *	,
		const TQString &	group = `TQString::null`
	)

virtual

Definition at line 372 of file tdefileview.cpp.

◆ removeItem()

void KFileView::removeItem ( const KFileItem * item )

virtual

Removes an item from the list; has to be implemented by the view.

Call KFileView::removeItem( item ) after removing it.

Reimplemented in KCombiView, KFileDetailView, KFileIconView, and KFilePreview.

Definition at line 346 of file tdefileview.cpp.

◆ selectAll()

void KFileView::selectAll ( )

Definition at line 312 of file tdefileview.cpp.

virtual

Definition at line 336 of file tdefileview.cpp.

◆ setCurrentItem() [1/2]

void KFileView::setDropOptions_impl ( int options )

protected

Definition at line 402 of file tdefileview.cpp.

◆ setOnlyDoubleClickSelectsFiles()

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 320 of file tdefileview.h.

◆ setParentView()

void KFileView::setParentView ( KFileView * parent )

virtual

Definition at line 90 of file tdefileview.cpp.

		bool	enable
	)

pure virtual

Tells the view that it should highlight the item.

This function must be implemented by the view.

Implemented in KCombiView, KFileDetailView, KFileIconView, and KFilePreview.

◆ setSelectionMode()

void KFileView::setSelectionMode ( KFile::SelectionMode sm )

virtual

Definition at line 331 of file tdefileview.cpp.

◆ setSorting()

void KFileView::setSorting ( TQDir::SortSpec sort )

virtual

Sets the sorting order of the view.

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

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

See also: sortingKey

Reimplemented in KCombiView, KFileIconView, KFilePreview, and KFileDetailView.

Definition at line 151 of file tdefileview.cpp.

◆ setViewMode()

void KFileView::setViewMode ( ViewMode vm )

virtual

Definition at line 341 of file tdefileview.cpp.

◆ setViewName()

void KFileView::setViewName ( const TQString & name )

inline

Sets the name of the view, which could be displayed somewhere.

E.g. "Image Preview".

Definition at line 239 of file tdefileview.h.

◆ signaler()

KFileViewSignaler * KFileView::signaler ( ) const

inline

Definition at line 346 of file tdefileview.h.

◆ sorting()

TQDir::SortSpec KFileView::sorting ( ) const

inline

Returns the sorting order of the internal list.

Newly added files are added through this sorting.

Definition at line 176 of file tdefileview.h.

◆ sortingKey() [1/2]

TQString KFileView::sortingKey	(	const TQString &	value,
		bool	isDir,
		int	sortSpec
	)

static

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

TQIconView or TQListView. Their Item-classes usually have a setKey( const TQString& ) method or a virtual method TQString 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 TQDir::SortSpec flags. Currently, the values IgnoreCase, Reversed and DirsFirst are taken into account.

Definition at line 380 of file tdefileview.cpp.

◆ sortingKey() [2/2]

TQString KFileView::sortingKey	(	TDEIO::filesize_t	value,
		bool	isDir,
		int	sortSpec
	)

static

An overloaded method that takes not a TQString, 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 TDEIO::filesize_t because of ambiguity problems.

Definition at line 389 of file tdefileview.cpp.

◆ sortReversed()

void KFileView::sortReversed ( )

Definition at line 164 of file tdefileview.cpp.

◆ updateNumbers()

bool KFileView::updateNumbers ( const KFileItem * i )

Returns: true if the item fits the view mode

Definition at line 110 of file tdefileview.cpp.

◆ updateView() [1/2]

void KFileView::updateView ( bool f = true )

virtual

does a repaint of the view.

The default implementation calls

widget()->repaint(f)

KFileView::widget

virtual TQWidget * widget()=0

a pure virtual function to get a TQWidget, that can be added to other widgets.

Reimplemented in KCombiView, KFileDetailView, KFileIconView, and KFilePreview.

Definition at line 259 of file tdefileview.cpp.

◆ updateView() [2/2]

void KFileView::updateView ( const KFileItem * )
