DESCRIPTION
       The QListViewItem class implements a list view item.

       A list view item is a multi-column object capable of displaying itself
       in a QListView.

       The easiest way to use QListViewItem is to construct one with a few
       constant strings, and either a QListView or another QListViewItem as
       parent.

	       (void) new QListViewItem( listView, "Column 1", "Column 2" );
	       (void) new QListViewItem( listView->firstChild(), "A", "B", "C" );
       We've discarded the pointers to the items since we can still access
       them via their parent listView. By default, QListView sorts its items;
       this can be switched off with QListView::setSorting(-1).

       The parent must be another QListViewItem or a QListView. If the parent
       is a QListView, the item becomes a top-level item within that
       QListView. If the parent is another QListViewItem, the item becomes a
       child of that list view item.

       If you keep the pointer, you can set or change the texts using
       setText(), add pixmaps using setPixmap(), change its mode using
       setSelectable(), setSelected(), setOpen() and setExpandable(). You'll
       also be able to change its height using setHeight(), and traverse its
       sub-items. You don't have to keep the pointer since you can get a
       pointer to any QListViewItem in a QListView using
       QListView::selectedItem(), QListView::currentItem(),
       QListView::firstChild(), QListView::lastItem() and
       QListView::findItem().

       If you call delete on a list view item, it will be deleted as expected,
       and as usual for QObjects, if it has any child items (to any depth),
       all these will be deleted too.

       QCheckListItems are list view items that have a checkbox or radio
       button and can be used in place of plain QListViewItems.

       You can traverse the tree as if it were a doubly-linked list using
       itemAbove() and itemBelow(); they return pointers to the items directly
       above and below this item on the screen (even if none of them are
       actually visible at the moment).

       Here's how to traverse all of an item's children (but not its
       children's children, etc.): Example:

	       QListViewItem * myChild = myItem->firstChild();
	       while( myChild ) {
		   doSomething( myChild );
		   myChild = myChild->nextSibling();
	       }

       If you want to iterate over every item, to any level of depth use an
       iterator. To iterate over the entire tree, initialize the iterator with
       the list view itself; to iterate starting from a particular item,
       initialize the iterator with the item:

	       QListViewItemIterator it( listview );
	       while ( it.current() ) {
		   QListViewItem *item = it.current();
		   doSomething( item );
		   ++it;
	       }

       Note that the order of the children will change when the sorting order
       changes and is undefined if the items are not visible. You can,
       however, call enforceSortOrder() at any time; QListView will always
       call it before it needs to show an item.

       Many programs will need to reimplement QListViewItem. The most commonly
       reimplemented functions are: <center>.nf

       </center>

       Some subclasses call setExpandable(TRUE) even when they have no
       children, and populate themselves when setup() or setOpen(TRUE) is
       called. The dirview/dirview.cpp example program uses this technique to
       start up quickly: The files and subdirectories in a directory aren't
       inserted into the tree until they're actually needed.

MEMBER FUNCTION DOCUMENTATION
QListViewItem::QListViewItem ( QListView * parent )
       Constructs a new top-level list view item in the QListView parent.

QListViewItem::QListViewItem ( QListViewItem * parent )
       Constructs a new list view item that is a child of parent and first in
       the parent's list of children.

QListViewItem::QListViewItem ( QListView * parent, QListViewItem * after )
       Constructs an empty list view item that is a child of parent and is
       after item after in the parent's list of children. Since parent is a
       QListView the item will be a top-level item.

QListViewItem::QListViewItem ( QListViewItem * parent, QListViewItem * after )

       Constructs an empty list view item that is a child of parent and is
       after item after in the parent's list of children.

QListViewItem::QListViewItem ( QListView * parent, QString label1, QString
       label2 = QString::null, QString label3 = QString::null, QString label4
       = QString::null, QString label5 = QString::null, QString label6 =
       QString::null, QString label7 = QString::null, QString label8 =
       QString::null )
       Constructs a new top-level list view item in the QListView parent, with
       up to eight constant strings, label1, label2, label3, label4, label5,
       label6, label7 and label8 defining its columns' contents.

       See also setText().

QListViewItem::QListViewItem ( QListViewItem * parent, QString label1, QString
       label2 = QString::null, QString label3 = QString::null, QString label4
       = QString::null, QString label5 = QString::null, QString label6 =
       QString::null, QString label7 = QString::null, QString label8 =
       QString::null )
       Constructs a new list view item as a child of the QListViewItem parent
       with up to eight constant strings, label1, label2, label3, label4,
       label5, label6, label7 and label8 as columns' contents.

       See also setText().

QListViewItem::QListViewItem ( QListView * parent, QListViewItem * after,
       QString label1, QString label2 = QString::null, QString label3 =
       QString::null, QString label4 = QString::null, QString label5 =
       QString::null, QString label6 = QString::null, QString label7 =
       QString::null, QString label8 = QString::null )
       Constructs a new list view item in the QListView parent that is
       included after item after and that has up to eight column texts,
       label1, label2, label3, label4, label5, label6, label7 andlabel8.

       Note that the order is changed according to QListViewItem::key() unless
       the list view's sorting is disabled using QListView::setSorting(-1).

       See also setText().

QListViewItem::QListViewItem ( QListViewItem * parent, QListViewItem * after,
       QString label1, QString label2 = QString::null, QString label3 =
       QString::null, QString label4 = QString::null, QString label5 =
       QString::null, QString label6 = QString::null, QString label7 =
       QString::null, QString label8 = QString::null )
       Constructs a new list view item as a child of the QListViewItem parent.
       It is inserted after item after and may contain up to eight strings,
       label1, label2, label3, label4, label5, label6, label7 and label8 as
       column entries.

       Note that the order is changed according to QListViewItem::key() unless
       the list view's sorting is disabled using QListView::setSorting(-1).

       See also setText().

QListViewItem::~QListViewItem () [virtual]
       Destroys the item, deleting all its children and freeing up all
       allocated resources.

bool QListViewItem::acceptDrop ( const QMimeSource * mime ) const [virtual]
       Returns TRUE if the item can accept drops of type QMimeSource mime;
       otherwise returns FALSE.

       The default implementation does nothing and returns FALSE. A subclass
       must reimplement this to accept drops.

void QListViewItem::activate () [virtual protected]
       This virtual function is called whenever the user presses the mouse on
       this item or presses Space on it.

       See also activatedPos().

       Reimplemented in QCheckListItem.

bool QListViewItem::activatedPos ( QPoint & pos ) [protected]
       When called from a reimplementation of activate(), this function gives
       information on how the item was activated. Otherwise the behavior is
       undefined.

       If activate() was caused by a mouse press, the function sets pos to
       where the user clicked and returns TRUE; otherwise it returns FALSE and
       does not change pos.

       pos is relative to the top-left corner of this item.

       Warning: We recommend that you ignore this function; it is scheduled to
       become obsolete.

       See also activate().

void QListViewItem::cancelRename ( int col ) [virtual protected]
       This function is called if the user cancels in-place renaming of this
       item in column col (e.g. by pressing Esc).

       See also okRename().

int QListViewItem::childCount () const
       Returns how many children this item has. The count only includes the
       item's immediate children.

int QListViewItem::compare ( QListViewItem * i, int col, bool ascending )
       const [virtual]
       Compares this list view item to i using the column col in ascending
       order. Returns < 0 if this item is less than i, 0 if they are equal and
       > 0 if this item is greater than i.

       This function is used for sorting.

       The default implementation compares the item keys (key()) using
       QString::localeAwareCompare(). A reimplementation can use different
       values and a different comparison function. Here is a reimplementation
       that uses plain Unicode comparison:

	   int MyListViewItem::compare( QListViewItem *i, int col,
					bool ascending ) const
	   {
	       return key( col, ascending ).compare( i->key( col, ascending) );
	   }
       We don't recommend using ascending so your code can safely ignore it.

       See also key(), QString::localeAwareCompare(), and QString::compare().

int QListViewItem::depth () const
       Returns the depth of this item.

       Example: dirview/dirview.cpp.

bool QListViewItem::dragEnabled () const
       Returns TRUE if this item can be dragged; otherwise returns FALSE.

       See also setDragEnabled().

void QListViewItem::dragEntered () [virtual protected]
       This function is called when a drag enters the item's bounding
       rectangle.

       The default implementation does nothing, subclasses may need to
       reimplement this function.

void QListViewItem::dragLeft () [virtual protected]
       This function is called when a drag leaves the item's bounding
       rectangle.

       The default implementation does nothing, subclasses may need to
       reimplement this function.

bool QListViewItem::dropEnabled () const
       Returns TRUE if this item accepts drops; otherwise returns FALSE.

       See also setDropEnabled() and acceptDrop().

void QListViewItem::dropped ( QDropEvent * e ) [virtual protected]
       This function is called when something was dropped on the item. e
       contains all the information about the drop.

       The default implementation does nothing, subclasses may need to
       reimplement this function.

void QListViewItem::enforceSortOrder () const [virtual protected]
       Makes sure that this object's children are sorted appropriately.

       This only works if every item from the root item down to this item is
       already sorted.

       See also sortChildItems().

QListViewItem * QListViewItem::firstChild () const
       Returns the first (top) child of this item, or 0 if this item has no
       children.

       Note that the children are not guaranteed to be sorted properly.
       QListView and QListViewItem try to postpone or avoid sorting to the
       greatest degree possible, in order to keep the user interface snappy.

       See also nextSibling() and sortChildItems().

       Example: checklists/checklists.cpp.

int QListViewItem::height () const
       Returns the height of this item in pixels. This does not include the
       height of any children; totalHeight() returns that.

void QListViewItem::insertItem ( QListViewItem * newChild ) [virtual]
       Inserts newChild into this list view item's list of children. You
       should not need to call this function; it is called automatically by
       the constructor of newChild.

       Warning: If you are using Single selection mode, then you should only
       insert unselected items.

void QListViewItem::invalidateHeight () [virtual]
       Invalidates the cached total height of this item, including all open
       children.

       See also setHeight(), height(), and totalHeight().

bool QListViewItem::isEnabled () const
       Returns TRUE if this item is enabled; otherwise returns FALSE.

       See also setEnabled().

bool QListViewItem::isExpandable () const
       Returns TRUE if this item is expandable even when it has no children;
       otherwise returns FALSE.

bool QListViewItem::isOpen () const
       Returns TRUE if this list view item has children and they are not
       explicitly hidden; otherwise returns FALSE.

       See also setOpen().

bool QListViewItem::isSelectable () const
       Returns TRUE if the item is selectable (as it is by default); otherwise
       returns FALSE

       See also setSelectable().

bool QListViewItem::isSelected () const
       Returns TRUE if this item is selected; otherwise returns FALSE.

       See also setSelected(), QListView::setSelected(), and
       QListView::selectionChanged().

       Example: listviews/listviews.cpp.

bool QListViewItem::isVisible () const
       Returns TRUE if the item is visible; otherwise returns FALSE.

       See also setVisible().

QListViewItem * QListViewItem::itemAbove ()
       Returns a pointer to the item immediately above this item on the
       screen. This is usually the item's closest older sibling, but it may
       also be its parent or its next older sibling's youngest child, or
       something else if anyoftheabove->height() returns 0. Returns 0 if there
       is no item immediately above this item.

       This function assumes that all parents of this item are open (i.e. that
       this item is visible, or can be made visible by scrolling).

       This function might be relatively slow because of the tree traversions
       needed to find the correct item.

       See also itemBelow() and QListView::itemRect().

QListViewItem * QListViewItem::itemBelow ()
       Returns a pointer to the item immediately below this item on the
       screen. This is usually the item's eldest child, but it may also be its
       next younger sibling, its parent's next younger sibling, grandparent's,
       etc., or something else if anyoftheabove->height() returns 0. Returns 0
       if there is no item immediately below this item.

       This function assumes that all parents of this item are open (i.e. that
       this item is visible or can be made visible by scrolling).

       See also itemAbove() and QListView::itemRect().

       Example: dirview/dirview.cpp.

int QListViewItem::itemPos () const
       Returns the y coordinate of this item in the list view's coordinate
       system. This function is normally much slower than QListView::itemAt(),
       but it works for all items whereas QListView::itemAt() normally only
       works for items on the screen.

       See also QListView::itemAt(), QListView::itemRect(), and
       QListView::itemPos().

QString QListViewItem::key ( int column, bool ascending ) const [virtual]
       Returns a key that can be used for sorting by column column. The
       default implementation returns text(). Derived classes may also
       incorporate the order indicated by ascending into this key, although
       this is not recommended.

       If you want to sort on non-alphabetical data, e.g. dates, numbers,
       etc., it is more efficient to reimplement compare().

       See also compare() and sortChildItems().

QListView * QListViewItem::listView () const
       Returns a pointer to the list view containing this item.

       Note that this function traverses the items to the root to find the
       listview. This function will return 0 for taken items - see
       QListViewItem::takeItem()

void QListViewItem::moveItem ( QListViewItem * after )
       Move the item to be after item after, which must be one of the item's
       siblings. To move an item in the hierarchy, use takeItem() and
       insertItem().

       Note that this function will have no effect if sorting is enabled in
       the list view.

bool QListViewItem::multiLinesEnabled () const
       Returns TRUE if the item can display multiple lines of text in its
       columns; otherwise returns FALSE.

QListViewItem * QListViewItem::nextSibling () const
       Returns the sibling item below this item, or 0 if there is no sibling
       item after this item.

       Note that the siblings are not guaranteed to be sorted properly.
       QListView and QListViewItem try to postpone or avoid sorting to the
       greatest degree possible, in order to keep the user interface snappy.

       See also firstChild() and sortChildItems().

       Example: xml/tagreader-with-features/structureparser.cpp.

void QListViewItem::okRename ( int col ) [virtual protected]
       This function is called if the user presses Enter during in-place
       renaming of the item in column col.

       See also cancelRename().

void QListViewItem::paintBranches ( QPainter * p, const QColorGroup & cg, int
       w, int y, int h ) [virtual]
       Paints a set of branches from this item to (some of) its children.

       Painter p is set up with clipping and translation so that you can only
       draw in the rectangle that needs redrawing; cg is the color group to
       use; the update rectangle is at (0, 0) and has size width w by height
       h. The top of the rectangle you own is at y (which is never greater
       than 0 but can be outside the window system's allowed coordinate
       range).

       The update rectangle is in an undefined state when this function is
       called; this function must draw on all of the pixels.

       See also paintCell() and QListView::drawContentsOffset().

void QListViewItem::paintCell ( QPainter * p, const QColorGroup & cg, int
       column, int width, int align ) [virtual]
       This virtual function paints the contents of one column of an item and
       aligns it as described by align.

       p is a QPainter open on the relevant paint device. p is translated so
       (0, 0) is the top-left pixel in the cell and width-1, height()-1 is the
       bottom-right pixel in the cell. The other properties of p (pen, brush,
       etc) are undefined. cg is the color group to use. column is the logical
       column number within the item that is to be painted; 0 is the column
       which may contain a tree.

       This function may use QListView::itemMargin() for readability spacing
       on the left and right sides of data such as text, and should honor
       isSelected() and QListView::allColumnsShowFocus().

       If you reimplement this function, you should also reimplement width().

       The rectangle to be painted is in an undefined state when this function
       is called, so you must draw on all the pixels. The painter p has the
       right font on entry.

       See also paintBranches() and QListView::drawContentsOffset().

       Example: listviews/listviews.cpp.

       Reimplemented in QCheckListItem.

void QListViewItem::paintFocus ( QPainter * p, const QColorGroup & cg, const
       QRect & r ) [virtual]
       Paints a focus indicator on the rectangle r using painter p and colors
       cg.

       p is already clipped.

       See also paintCell(), paintBranches(), and
       QListView::allColumnsShowFocus.

       Reimplemented in QCheckListItem.

QListViewItem * QListViewItem::parent () const
       Returns the parent of this item, or 0 if this item has no parent.

       See also firstChild() and nextSibling().

       Examples:

const QPixmap * QListViewItem::pixmap ( int column ) const [virtual]
       Returns the pixmap for column, or 0 if there is no pixmap for column.

       See also setText() and setPixmap().

       Example: dirview/dirview.cpp.

void QListViewItem::removeItem ( QListViewItem * item ) [virtual]
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

       This function has been renamed takeItem().

bool QListViewItem::renameEnabled ( int col ) const
       Returns TRUE if this item can be in-place renamed in column col;
       otherwise returns FALSE.

void QListViewItem::repaint () const
       Repaints this item on the screen if it is currently visible.

       Example: addressbook/centralwidget.cpp.

int QListViewItem::rtti () const [virtual]
       Returns 0.

       Make your derived classes return their own values for rtti(), so that
       you can distinguish between different kinds of list view items. You
       should use values greater than 1000 to allow for extensions to this
       class.

       Reimplemented in QCheckListItem.

void QListViewItem::setDragEnabled ( bool allow ) [virtual]
       If allow is TRUE, the list view starts a drag (see
       QListView::dragObject()) when the user presses and moves the mouse on
       this item.

void QListViewItem::setDropEnabled ( bool allow ) [virtual]
       If allow is TRUE, the list view accepts drops onto the item; otherwise
       drops are not allowed.

void QListViewItem::setEnabled ( bool b ) [virtual]
       If b is TRUE the item is enabled; otherwise it is disabled. Disabled
       items are drawn differently (e.g. grayed-out) and are not accessible by
       the user.

void QListViewItem::setExpandable ( bool enable ) [virtual]
       Sets this item to be expandable even if it has no children if enable is
       TRUE, and to be expandable only if it has children if enable is FALSE
       (the default).

       The dirview example uses this in the canonical fashion. It checks
       whether the directory is empty in setup() and calls setExpandable(TRUE)
       if not; in setOpen() it reads the contents of the directory and inserts
       items accordingly. This strategy means that dirview can display the
       entire file system without reading very much at startup.

       Note that root items are not expandable by the user unless
       QListView::setRootIsDecorated() is set to TRUE.

       See also setSelectable().

void QListViewItem::setHeight ( int height ) [virtual protected]
       Sets this item's height to height pixels. This implicitly changes
       totalHeight(), too.

       Note that a font change causes this height to be overwritten unless you
       reimplement setup().

       For best results in Windows style we suggest using an even number of
       pixels.

       See also height(), totalHeight(), and isOpen().

void QListViewItem::setMultiLinesEnabled ( bool b ) [virtual]
       If b is TRUE each of the item's columns may contain multiple lines of
       text; otherwise each of them may only contain a single line.

void QListViewItem::setOpen ( bool o ) [virtual]
       Opens or closes an item, i.e. shows or hides an item's children.

       If o is TRUE all child items are shown initially. The user can hide
       them by clicking the - icon to the left of the item. If o is FALSE, the
       children of this item are initially hidden. The user can show them by
       clicking the + icon to the left of the item.

       See also height(), totalHeight(), and isOpen().

       Examples:

void QListViewItem::setPixmap ( int column, const QPixmap & pm ) [virtual]
       Sets the pixmap in column column to pm, if pm is non-null and different
       from the current pixmap, and if column is non-negative.

       See also pixmap() and setText().

       Example: dirview/dirview.cpp.

void QListViewItem::setRenameEnabled ( int col, bool b ) [virtual]
       If b is TRUE, this item can be in-place renamed in the column col by
       the user; otherwise it cannot be renamed in-place.

void QListViewItem::setSelectable ( bool enable ) [virtual]
       Sets this item to be selectable if enable is TRUE (the default) or not
       to be selectable if enable is FALSE.

       The user is not able to select a non-selectable item using either the
       keyboard or the mouse. This also applies for the application programmer
       (e.g. setSelected() respects this value).

       See also isSelectable().

void QListViewItem::setSelected ( bool s ) [virtual]
       If s is TRUE this item is selected; otherwise it is deselected.

       This function does not maintain any invariants or repaint anything --
       QListView::setSelected() does that.

       See also height() and totalHeight().

       Example: addressbook/centralwidget.cpp.

void QListViewItem::setText ( int column, const QString & text ) [virtual]
       Sets the text in column column to text, if column is a valid column
       number and text is different from the existing text.

       If text() has been reimplemented, this function may be a no-op.

       See also text() and key().

       Examples:

void QListViewItem::setVisible ( bool b )
       If b is TRUE, the item is made visible; otherwise it is hidden.

       If the item is not visible, itemAbove() and itemBelow() will never
       return this item, although you still can reach it by using e.g.
       QListViewItemIterator.

void QListViewItem::setup () [virtual]
       This virtual function is called before the first time QListView needs
       to know the height or any other graphical attribute of this object, and
       whenever the font, GUI style, or colors of the list view change.

       The default calls widthChanged() and sets the item's height to the
       height of a single line of text in the list view's font. (If you use
       icons, multi-line text, etc., you will probably need to call
       setHeight() yourself or reimplement it.)

       Example: dirview/dirview.cpp.

void QListViewItem::sort () [virtual]
       Sorts all this item's child items using the current sorting
       configuration (sort column and direction).

       See also enforceSortOrder().

void QListViewItem::sortChildItems ( int column, bool ascending ) [virtual]
       Sorts this item's children using column column. This is done in
       ascending order if ascending is TRUE and in descending order if
       ascending is FALSE.

       Asks some of the children to sort their children. (QListView and
       QListViewItem ensure that all on-screen objects are properly sorted but
       may avoid or defer sorting other objects in order to be more
       responsive.)

       See also key() and compare().

void QListViewItem::startRename ( int col ) [virtual]
       If in-place renaming of this item is enabled (see renameEnabled()),
       this function starts renaming the item in column col, by creating and
       initializing an edit box.

void QListViewItem::takeItem ( QListViewItem * item ) [virtual]
       Removes item from this object's list of children and causes an update
       of the screen display. The item is not deleted. You should not normally
       need to call this function because QListViewItem::~QListViewItem()
       calls it.

       The normal way to delete an item is to use delete.

       If you need to move an item from one place in the hierarchy to another
       you can use takeItem() to remove the item from the list view and then
       insertItem() to put the item back in its new position.

       If a taken item is part of a selection in Single selection mode, it is
       unselected and selectionChanged() is emitted. If a taken item is part
       of a selection in Multi or Extended selection mode, it remains
       selected.

       Warning: This function leaves item and its children in a state where
       most member functions are unsafe. Only a few functions work correctly
       on an item in this state, most notably insertItem(). The functions that
       work on taken items are explicitly documented as such.

       See also QListViewItem::insertItem().

QString QListViewItem::text ( int column ) const [virtual]
       Returns the text in column column, or QString::null if there is no text
       in that column.

       See also key() and paintCell().

       Examples:

int QListViewItem::totalHeight () const
       Returns the total height of this object, including any visible
       children. This height is recomputed lazily and cached for as long as
       possible.

       Functions which can affect the total height are, setHeight() which is
       used to set an item's height, setOpen() to show or hide an item's
       children, and invalidateHeight() to invalidate the cached height.

       See also height().

int QListViewItem::width ( const QFontMetrics & fm, const QListView * lv, int
       c ) const [virtual]
       Returns the number of pixels of width required to draw column c of list
       view lv, using the metrics fm without cropping. The list view
       containing this item may use this information depending on the
       QListView::WidthMode settings for the column.

       The default implementation returns the width of the bounding rectangle
       of the text of column c.

       See also listView(), widthChanged(), QListView::setColumnWidthMode(),
       and QListView::itemMargin.

void QListViewItem::widthChanged ( int c = -1 ) const
       Call this function when the value of width() may have changed for
       column c. Normally, you should call this if text(c) changes. Passing -1
       for c indicates that all columns may have changed. It is more efficient
       to pass -1 if two or more columns have changed than to call
       widthChanged() separately for each one.

       See also width().
