Member Function Documentation

◆ actionCollection()

TDEActionCollection * KFilePreview::actionCollection ( ) const

virtual

This overrides KFileView::actionCollection() by returning the actionCollection() of the KFileView (member left) it contains.

This means that KFilePreview will never create a TDEActionCollection object of its own.

Reimplemented from KFileView.

Definition at line 257 of file tdefilepreview.cpp.

◆ clear()

void KFilePreview::clear ( )

virtual

Clears the view and all item lists.

Reimplemented from KFileView.

Definition at line 174 of file tdefilepreview.cpp.

◆ clearSelection()

void KFilePreview::clearSelection ( )

virtual

Clears any selection, unhighlights everything.

Must be implemented by the view.

Implements KFileView.

Definition at line 180 of file tdefilepreview.cpp.

◆ clearView()

void KFilePreview::clearView ( )

virtual

pure virtual function, that should be implemented to clear the view.

At this moment the list is already empty

Implements KFileView.

Definition at line 142 of file tdefilepreview.cpp.

◆ currentFileItem()

KFileItem * KFilePreview::currentFileItem ( ) const

virtual

Returns: the "current" KFileItem, e.g. where the cursor is. Returns 0L when there is no current item (e.g. in an empty view). Subclasses have to implement this.

Implements KFileView.

Definition at line 214 of file tdefilepreview.cpp.

◆ ensureItemVisible()

void KFilePreview::ensureItemVisible ( const KFileItem * i )

virtual

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

by scrolling the view appropriately.

Implements KFileView.

Definition at line 237 of file tdefilepreview.cpp.

◆ fileView()

KFileView * KFilePreview::fileView ( ) const

inline

Returns: the current fileview

Definition at line 60 of file tdefilepreview.h.

◆ firstFileItem()

KFileItem * KFilePreview::firstFileItem ( ) const

virtual

Implements KFileView.

Definition at line 242 of file tdefilepreview.cpp.

◆ insertItem()

void KFilePreview::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 from KFileView.

Definition at line 130 of file tdefilepreview.cpp.

◆ invertSelection()

void KFilePreview::invertSelection ( )

virtual

Inverts the current selection, i.e.

selects all items, that were up to now not selected and deselects the other.

Reimplemented from KFileView.

Definition at line 191 of file tdefilepreview.cpp.

◆ isSelected()

bool KFilePreview::isSelected ( const KFileItem * ) const

virtual

Returns: whether the given item is currently selected. Must be implemented by the view.

Implements KFileView.

Definition at line 196 of file tdefilepreview.cpp.

◆ listingCompleted()

void KFilePreview::listingCompleted ( )

virtual

This hook is called when all items of the currently listed directory are listed and inserted into the view, i.e.

there won't come any new items anymore.

Reimplemented from KFileView.

Definition at line 169 of file tdefilepreview.cpp.

◆ nextItem()

KFileItem * KFilePreview::nextItem ( const KFileItem * item ) const

virtual

Implements KFileView.

Definition at line 247 of file tdefilepreview.cpp.

◆ prevItem()

KFileItem * KFilePreview::prevItem ( const KFileItem * item ) const

virtual

Implements KFileView.

Definition at line 252 of file tdefilepreview.cpp.

◆ readConfig()

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

virtual

Reimplemented from KFileView.

Definition at line 267 of file tdefilepreview.cpp.

◆ removeItem()

void KFilePreview::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 from KFileView.

Definition at line 160 of file tdefilepreview.cpp.

◆ selectAll()

void KFilePreview::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.

Reimplemented from KFileView.

Definition at line 186 of file tdefilepreview.cpp.

◆ setCurrentItem()

void KFilePreview::setCurrentItem ( const KFileItem * item )

virtual

Reimplement this to set item the current item in the view, e.g.

the item having focus.

Implements KFileView.

Definition at line 209 of file tdefilepreview.cpp.

◆ setFileView()

void KFilePreview::setFileView ( KFileView * view )

Delets the current view and sets the view to the given view.

The view is reparented to have this as parent, if necessary.

Definition at line 81 of file tdefilepreview.cpp.

◆ setPreviewWidget()

void KFilePreview::setPreviewWidget	(	const TQWidget *	w,
		const KURL &	u
	)

Definition at line 108 of file tdefilepreview.cpp.

◆ setSelected()

void KFilePreview::setSelected	(	const KFileItem *	,
		bool	enable
	)

virtual

Tells the view that it should highlight the item.

This function must be implemented by the view.

Implements KFileView.

Definition at line 205 of file tdefilepreview.cpp.

◆ setSelectionMode()

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

virtual

Reimplemented from KFileView.

Definition at line 201 of file tdefilepreview.cpp.

◆ setSorting()

void KFilePreview::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.

Reimplemented from KFileView.

Definition at line 136 of file tdefilepreview.cpp.

◆ slotHighlighted

void KFilePreview::slotHighlighted ( const KFileItem * item )

protectedvirtualslot

Definition at line 219 of file tdefilepreview.cpp.

◆ updateView() [1/2]

void KFilePreview::updateView ( bool f )

virtual

does a repaint of the view.

The default implementation calls

widget()->repaint(f)

KFilePreview::widget

virtual TQWidget * widget()

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

Definition: tdefilepreview.h:48

Reimplemented from KFileView.

Definition at line 148 of file tdefilepreview.cpp.

◆ updateView() [2/2]

void KFilePreview::updateView ( const KFileItem * i )

virtual

Reimplemented from KFileView.

Definition at line 155 of file tdefilepreview.cpp.

◆ virtual_hook()

void KFilePreview::virtual_hook	(	int	id,
		void *	data
	)

protectedvirtual

Reimplemented from KFileView.

Definition at line 277 of file tdefilepreview.cpp.

◆ widget()

virtual TQWidget * KFilePreview::widget ( )

inlinevirtual

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

This function is needed to make it possible for derived classes to derive from other widgets.

Implements KFileView.

Definition at line 48 of file tdefilepreview.h.

◆ writeConfig()

void KFilePreview::writeConfig	(	TDEConfig *	config,
		const TQString &	group = `TQString::null`
	)
