DESCRIPTION
       The QIconView class provides an area with movable labelled icons.

       A QIconView can display and manage a grid or other 2D layout of labelled icons. Each
       labelled icon is a QIconViewItem. Items (QIconViewItems) can be added or deleted at any
       time; items can be moved within the QIconView. Single or multiple items can be selected.
       Items can be renamed in-place. QIconView also supports drag and drop.

       Each item contains a label string, a pixmap or picture (the icon itself) and optionally a
       sort key. The sort key is used for sorting the items and defaults to the label string. The
       label string can be displayed below or to the right of the icon (see ItemTextPos).

       The simplest way to create a QIconView is to create a QIconView object and create some
       QIconViewItems with the QIconView as their parent, set the icon view's geometry and show
       it. For example:

	   QIconView *iv = new QIconView( this );
	   QDir dir( path, "*.xpm" );
	   for ( uint i = 0; i < dir.count(); i++ ) {
	       (void) new QIconViewItem( iv, dir[i], QPixmap( path + dir[i] ) );
	   }
	   iv->resize( 600, 400 );
	   iv->show();

       The QIconViewItem call passes a pointer to the QIconView we wish to populate, along with
       the label text and a QPixmap.

       When an item is inserted the QIconView allocates a position for it. Existing items are
       rearranged if autoArrange() is TRUE. The default arrangement is LeftToRight -- the
       QIconView fills up the left-most column from top to bottom, then moves one column right
       and fills that from top to bottom and so on. The arrangement can be modified with any of
       the following approaches:

       Call setArrangement(), e.g. with TopToBottom which will fill the top-most row from left to
       right, then moves one row down and fills that row from left to right and so on.

       Construct each QIconViewItem using a constructor which allows you to specify which item
       the new one is to follow.

       Call setSorting() or sort() to sort the items.

       The spacing between items is set with setSpacing(). Items can be laid out using a fixed
       grid using setGridX() and setGridY(); by default the QIconView calculates a grid
       dynamically. The position of items' label text is set with setItemTextPos(). The text's
       background can be set with setItemTextBackground(). The maximum width of an item and of
       its text are set with setMaxItemWidth() and setMaxItemTextLength(). The label text will be
       word-wrapped if it is too long; this is controlled by setWordWrapIconText(). If the label
       text is truncated, the user can still see the entire text in a tool tip if they hover the
       mouse over the item. This is controlled with setShowToolTips().

       Items which are selectable may be selected depending on the SelectionMode; the default is
       Single. Because QIconView offers multiple selection it must display keyboard focus and
       selection state separately. Therefore there are functions to set the selection state of an
       item (setSelected()) and to select which item displays keyboard focus (setCurrentItem()).
       When multiple items may be selected the icon view provides a rubberband, too.

       When in-place renaming is enabled (it is disabled by default), the user may change the
       item's label. They do this by selecting the item (single clicking it or navigating to it
       with the arrow keys), then single clicking it (or pressing F2), and entering their text.
       If no key has been set with QIconViewItem::setKey() the new text will also serve as the
       key. (See QIconViewItem::setRenameEnabled().)

       You can control whether users can move items themselves with setItemsMovable().

       Because the internal structure used to store the icon view items is linear, no iterator
       class is needed to iterate over all the items. Instead we iterate by getting the first
       item from the icon view and then each subsequent (QIconViewItem::nextItem()) from each
       item in turn:

	       for ( QIconViewItem *item = iv->firstItem(); item; item = item->nextItem() )
		   do_something( item );
       QIconView also provides currentItem(). You can search for an item using findItem()
       (searching by position or for label text) and with findFirstVisibleItem() and
       findLastVisibleItem(). The number of items is returned by count(). An item can be removed
       from an icon view using takeItem(); to delete an item use delete. All the items can be
       deleted with clear().

       The QIconView emits a wide range of useful signals, including selectionChanged(),
       currentChanged(), clicked(), moved() and itemRenamed().

Drag and Drop
       QIconView supports the drag and drop of items within the QIconView itself. It also
       supports the drag and drop of items out of or into the QIconView and drag and drop onto
       items themselves. The drag and drop of items outside the QIconView can be achieved in a
       simple way with basic functionality, or in a more sophisticated way which provides more
       power and control.

       The simple approach to dragging items out of the icon view is to subclass QIconView and
       reimplement QIconView::dragObject().

	   QDragObject *MyIconView::dragObject()
	   {
	       return new QTextDrag( currentItem()->text(), this );
	   }

       In this example we create a QTextDrag object, (derived from QDragObject), containing the
       item's label and return it as the drag object. We could just as easily have created a
       QImageDrag from the item's pixmap and returned that instead.

       QIconViews and their QIconViewItems can also be the targets of drag and drops. To make the
       QIconView itself able to accept drops connect to the dropped() signal. When a drop occurs
       this signal will be emitted with a QDragEvent and a QValueList of QIconDragItems. To make
       a QIconViewItem into a drop target subclass QIconViewItem and reimplement
       QIconViewItem::acceptDrop() and QIconViewItem::dropped().

	   bool MyIconViewItem::acceptDrop( const QMimeSource *mime ) const
	   {
	       if ( mime->provides( "text/plain" ) )
		   return TRUE;
	       return FALSE;
	   }
	   void MyIconViewItem::dropped( QDropEvent *evt, const QValueList<QIconDragItem>& )
	   {
	       QString label;
	       if ( QTextDrag::decode( evt, label ) )
		   setText( label );
	   }

       See iconview/simple_dd/main.h and iconview/simple_dd/main.cpp for a simple drag and drop
       example which demonstrates drag and drop between a QIconView and a QListBox.

       If you want to use extended drag-and-drop or have drag shapes drawn you must take a more
       sophisticated approach.

       The first part is starting drags -- you should use a QIconDrag (or a class derived from
       it) for the drag object. In dragObject() create the drag object, populate it with
       QIconDragItems and return it. Normally such a drag should offer each selected item's data.
       So in dragObject() you should iterate over all the items, and create a QIconDragItem for
       each selected item, and append these items with QIconDrag::append() to the QIconDrag
       object. You can use QIconDragItem::setData() to set the data of each item that should be
       dragged. If you want to offer the data in additional mime-types, it's best to use a class
       derived from QIconDrag, which implements additional encoding and decoding functions.

       When a drag enters the icon view, there is little to do. Simply connect to the dropped()
       signal and reimplement QIconViewItem::acceptDrop() and QIconViewItem::dropped(). If you've
       used a QIconDrag (or a subclass of it) the second argument to the dropped signal contains
       a QValueList of QIconDragItems -- you can access their data by calling
       QIconDragItem::data() on each one.

       For an example implementation of complex drag-and-drop look at the fileiconview example
       (qt/examples/fileiconview).

       See also QIconViewItem::setDragEnabled(), QIconViewItem::setDropEnabled(),
       QIconViewItem::acceptDrop(), QIconViewItem::dropped(), and Advanced Widgets.

   Member Type Documentation
QIconView::Arrangement
       This enum type determines in which direction the items flow when the view runs out of
       space.

       QIconView::LeftToRight - Items which don't fit into the view go further down (you get a
       vertical scrollbar)

       QIconView::TopToBottom - Items which don't fit into the view go further right (you get a
       horizontal scrollbar)

QIconView::ItemTextPos
       This enum type specifies the position of the item text in relation to the icon.

       QIconView::Bottom - The text is drawn below the icon.

       QIconView::Right - The text is drawn to the right of the icon.

QIconView::ResizeMode
       This enum type is used to tell QIconView how it should treat the positions of its icons
       when the widget is resized. The modes are:

       QIconView::Fixed - The icons' positions are not changed.

       QIconView::Adjust - The icons' positions are adjusted to be within the new geometry, if
       possible.

QIconView::SelectionMode
       This enumerated type is used by QIconView to indicate how it reacts to selection by the
       user. It has four values:

       QIconView::Single - When the user selects an item, any already-selected item becomes
       unselected and the user cannot unselect the selected item. This means that the user can
       never clear the selection. (The application programmer can, using
       QIconView::clearSelection().)

       QIconView::Multi - When the user selects an item, e.g. by navigating to it with the
       keyboard arrow keys or by clicking it, the selection status of that item is toggled and
       the other items are left alone.

       QIconView::Extended - When the user selects an item the selection is cleared and the new
       item selected. However, if the user presses the Ctrl key when clicking on an item, the
       clicked item gets toggled and all other items are left untouched. If the user presses the
       Shift key while clicking on an item, all items between the current item and the clicked
       item get selected or unselected, depending on the state of the clicked item. Also,
       multiple items can be selected by dragging the mouse while the left mouse button stays
       pressed.

       QIconView::NoSelection - Items cannot be selected.

       To summarise: Single is a real single-selection icon view; Multi a real multi-selection
       icon view; Extended is an icon view in which users can select multiple items but usually
       want to select either just one or a range of contiguous items; and NoSelection mode is for
       an icon view where the user can look but not touch.

MEMBER FUNCTION DOCUMENTATION
QIconView::QIconView ( QWidget * parent = 0, const char * name = 0, WFlags f = 0 )
       Constructs an empty icon view called name, with parent parent and using the widget flags
       f.

QIconView::~QIconView () [virtual]
       Destroys the icon view and deletes all items.

void QIconView::adjustItems () [virtual protected slot]
       Adjusts the positions of the items to the geometry of the icon view.

void QIconView::arrangeItemsInGrid ( const QSize & grid, bool update = TRUE ) [virtual slot]
       This variant uses grid instead of (gridX(), gridY()). If grid is invalid (see
       QSize::isValid()), arrangeItemsInGrid() calculates a valid grid itself and uses that.

       If update is TRUE (the default) the viewport is repainted.

       Example: fileiconview/qfileiconview.h.

void QIconView::arrangeItemsInGrid ( bool update = TRUE ) [virtual slot]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Arranges all the items in the grid given by gridX() and gridY().

       Even if sorting() is enabled, the items are not sorted by this function. If you want to
       sort or rearrange the items, use iconview->sort(iconview->sortDirection()).

       If update is TRUE (the default), the viewport is repainted as well.

       See also QIconView::gridX, QIconView::gridY, and QIconView::sort().

Arrangement QIconView::arrangement () const
       Returns the arrangement mode of the icon view. See the "arrangement" property for details.

bool QIconView::autoArrange () const
       Returns TRUE if the icon view rearranges its items when a new item is inserted; otherwise
       returns FALSE. See the "autoArrange" property for details.

void QIconView::clear () [virtual]
       Clears the icon view. All items are deleted.

void QIconView::clearSelection () [virtual]
       Unselects all the items.

void QIconView::clicked ( QIconViewItem * item ) [signal]
       This signal is emitted when the user clicks any mouse button. If item is non-null, the
       cursor is on item. If item is null, the mouse cursor isn't on any item.

       See also mouseButtonClicked(), rightButtonClicked(), and pressed().

void QIconView::clicked ( QIconViewItem * item, const QPoint & pos ) [signal]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       This signal is emitted when the user clicks any mouse button on an icon view item. item is
       a pointer to the item that has been clicked.

       pos is the position of the mouse cursor in the global coordinate system
       (QMouseEvent::globalPos()). (If the click's press and release differ by a pixel or two,
       pos is the position at release time.)

       See also mouseButtonClicked(), rightButtonClicked(), and pressed().

void QIconView::contextMenuRequested ( QIconViewItem * item, const QPoint & pos ) [signal]
       This signal is emitted when the user invokes a context menu with the right mouse button or
       with special system keys, with item being the item under the mouse cursor or the current
       item, respectively.

       pos is the position for the context menu in the global coordinate system.

uint QIconView::count () const
       Returns the number of items in the icon view. See the "count" property for details.

void QIconView::currentChanged ( QIconViewItem * item ) [signal]
       This signal is emitted when a new item becomes current. item is the new current item (or 0
       if no item is now current).

       See also currentItem().

QIconViewItem * QIconView::currentItem () const
       Returns a pointer to the current item of the icon view, or 0 if no item is current.

       See also setCurrentItem(), firstItem(), and lastItem().

void QIconView::doAutoScroll () [virtual protected slot]
       Performs autoscrolling when selecting multiple icons with the rubber band.

void QIconView::doubleClicked ( QIconViewItem * item ) [signal]
       This signal is emitted when the user double-clicks on item.

QDragObject * QIconView::dragObject () [virtual protected]
       Returns the QDragObject that should be used for drag-and-drop. This function is called by
       the icon view when starting a drag to get the dragobject that should be used for the drag.
       Subclasses may reimplement this.

       See also QIconDrag.

       Examples:

void QIconView::drawBackground ( QPainter * p, const QRect & r ) [virtual protected]
       This function is called to draw the rectangle r of the background using the painter p.

       The default implementation fills r with the viewport's backgroundBrush(). Subclasses may
       reimplement this to draw custom backgrounds.

       See also contentsX, contentsY, and drawContents().

void QIconView::drawRubber ( QPainter * p ) [virtual protected]
       Draws the rubber band using the painter p.

void QIconView::dropped ( QDropEvent * e, const QValueList<QIconDragItem> & lst ) [signal]
       This signal is emitted when a drop event occurs in the viewport (but not on any icon)
       which the icon view itself can't handle.

       e provides all the information about the drop. If the drag object of the drop was a
       QIconDrag, lst contains the list of the dropped items. You can get the data using
       QIconDragItem::data() on each item. If the lst is empty, i.e. the drag was not a
       QIconDrag, you have to decode the data in e and work with that.

       Note QIconViewItems may be drop targets; if a drop event occurs on an item the item
       handles the drop.

       Examples:

void QIconView::emitSelectionChanged ( QIconViewItem * i = 0 ) [protected]
       Emits a signal to indicate selection changes. i is the QIconViewItem that was selected or
       de-selected.

       You should never need to call this function.

void QIconView::ensureItemVisible ( QIconViewItem * item )
       Makes sure that item is entirely visible. If necessary, ensureItemVisible() scrolls the
       icon view.

       See also ensureVisible().

QIconViewItem * QIconView::findFirstVisibleItem ( const QRect & r ) const
       Finds the first item whose bounding rectangle overlaps r and returns a pointer to that
       item. r is given in content coordinates. Returns 0 if no item overlaps r.

       If you want to find all items that touch r, you will need to use this function and
       nextItem() in a loop ending at findLastVisibleItem() and test QIconViewItem::rect() for
       each of these items.

       See also findLastVisibleItem() and QIconViewItem::rect().

QIconViewItem * QIconView::findItem ( const QPoint & pos ) const
       Returns a pointer to the item that contains point pos, which is given in contents
       coordinates, or 0 if no item contains point pos.

QIconViewItem * QIconView::findItem ( const QString & text, ComparisonFlags compare = BeginsWith
       ) const
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Returns a pointer to the first item whose text begins with text, or 0 if no such item
       could be found. Use the compare flag to control the comparison behaviour. (See
       Qt::StringComparisonMode.)

QIconViewItem * QIconView::findLastVisibleItem ( const QRect & r ) const
       Finds the last item whose bounding rectangle overlaps r and returns a pointer to that
       item. r is given in content coordinates. Returns 0 if no item overlaps r.

       See also findFirstVisibleItem().

QIconViewItem * QIconView::firstItem () const
       Returns a pointer to the first item of the icon view, or 0 if there are no items in the
       icon view.

void QIconView::insertInGrid ( QIconViewItem * item ) [virtual protected]
       Inserts the QIconViewItem item in the icon view's grid. You should never need to call this
       function. Instead, insert QIconViewItems by creating them with a pointer to the QIconView
       that they are to be inserted into.

void QIconView::insertItem ( QIconViewItem * item, QIconViewItem * after = 0L ) [virtual]
       Inserts the icon view item item after after. If after is 0, item is appended after the
       last item.

       You should never need to call this function. Instead create QIconViewItem's and associate
       them with your icon view like this:

	       (void) new QIconViewItem( myIconview, "The text of the item", aPixmap );

void QIconView::invertSelection () [virtual]
       Inverts the selection. Works only in Multi and Extended selection mode.

void QIconView::itemRenamed ( QIconViewItem * item, const QString & name ) [signal]
       This signal is emitted when item has been renamed to name, usually by in-place renaming.

       See also QIconViewItem::setRenameEnabled() and QIconViewItem::rename().

void QIconView::itemRenamed ( QIconViewItem * item ) [signal]
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       This signal is emitted when item has been renamed, usually by in-place renaming.

       See also QIconViewItem::setRenameEnabled() and QIconViewItem::rename().

       Returns the position where the text of each item is drawn. See the "itemTextPos" property
       for details.

bool QIconView::itemsMovable () const
       Returns TRUE if the user is allowed to move items around in the icon view; otherwise
       returns FALSE. See the "itemsMovable" property for details.

QIconViewItem * QIconView::lastItem () const
       Returns a pointer to the last item of the icon view, or 0 if there are no items in the
       icon view.

       See also firstItem() and currentItem().

QIconViewItem * QIconView::makeRowLayout ( QIconViewItem * begin, int & y, bool & changed )
       [protected]

void QIconView::setSelected ( QIconViewItem * item, bool s, bool cb = FALSE ) [virtual]
       Selects or unselects item depending on s, and may also unselect other items, depending on
       QIconView::selectionMode() and cb.

       If s is FALSE, item is unselected.

       If s is TRUE and QIconView::selectionMode() is Single, item is selected, and the item
       which was selected is unselected.

       If s is TRUE and QIconView::selectionMode() is Extended, item is selected. If cb is TRUE,
       the selection state of the icon view's other items is left unchanged. If cb is FALSE (the
       default) all other items are unselected.

       If s is TRUE and QIconView::selectionMode() is Multi item is selected.

       Note that cb is used only if QIconView::selectionMode() is Extended. cb defaults to FALSE.

       All items whose selection status is changed repaint themselves.

void QIconView::setSorting ( bool sort, bool ascending = TRUE )
       If sort is TRUE, this function sets the icon view to sort items when a new item is
       inserted. If sort is FALSE, the icon view will not be sorted.

       Note that autoArrange() must be TRUE for sorting to take place.

       If ascending is TRUE (the default), items are sorted in ascending order. If ascending is
       FALSE, items are sorted in descending order.

       QIconViewItem::compare() is used to compare pairs of items. The sorting is based on the
       items' keys; these default to the items' text unless specifically set to something else.

       See also QIconView::autoArrange, QIconView::autoArrange, sortDirection, sort(), and
       QIconViewItem::setKey().

void QIconView::setSpacing ( int sp ) [virtual]

       "wordWrapIconText" property for details.

bool QIconView::showToolTips () const
       Returns TRUE if the icon view will display a tool tip with the complete text for any
       truncated item text; otherwise returns FALSE. See the "showToolTips" property for details.

void QIconView::slotUpdate () [virtual protected slot]
       This slot is used for a slightly-delayed update.

       The icon view is not redrawn immediately after inserting a new item but after a very small
       delay using a QTimer. This means that when many items are inserted in a loop the icon view
       is probably redrawn only once at the end of the loop. This makes the insertions both
       flicker-free and faster.

void QIconView::sort ( bool ascending = TRUE ) [virtual]
       Sorts and rearranges all the items in the icon view. If ascending is TRUE, the items are
       sorted in increasing order, otherwise they are sorted in decreasing order.

       QIconViewItem::compare() is used to compare pairs of items. The sorting is based on the
       items' keys; these default to the items' text unless specifically set to something else.

       Note that this function sets the sort order to ascending.

       See also QIconViewItem::key(), QIconViewItem::setKey(), QIconViewItem::compare(),
       QIconView::setSorting(), and QIconView::sortDirection.

bool QIconView::sortDirection () const
       Returns TRUE if the sort direction for inserting new items is ascending;; otherwise
       returns FALSE. See the "sortDirection" property for details.

bool QIconView::sorting () const
       Returns TRUE if the icon view sorts on insertion; otherwise returns FALSE. See the
       "sorting" property for details.

int QIconView::spacing () const
       Returns the space in pixels between icon view items. See the "spacing" property for
       details.

void QIconView::startDrag () [virtual protected]
       Starts a drag.

void QIconView::takeItem ( QIconViewItem * item ) [virtual]
       Takes the icon view item item out of the icon view and causes an update of the screen
       display. The item is not deleted. You should normally not need to call this function
       because QIconViewItem::~QIconViewItem() calls it. The normal way to delete an item is to
       delete it.

bool QIconView::wordWrapIconText () const
       Returns TRUE if the item text will be word-wrapped if it is too long; otherwise returns
       FALSE. See the "wordWrapIconText" property for details.

       This can be LeftToRight or TopToBottom. The default is LeftToRight.

       Set this property's value with setArrangement() and get this property's value with
       arrangement().

bool autoArrange
       This property holds whether the icon view rearranges its items when a new item is
       inserted.

       The default is TRUE.

       Note that if the icon view is not visible at the time of insertion, QIconView defers all
       position-related work until it is shown and then calls arrangeItemsInGrid().

       Set this property's value with setAutoArrange() and get this property's value with
       autoArrange().

uint count
       This property holds the number of items in the icon view.

       Get this property's value with count().

int gridX
       This property holds the horizontal grid of the icon view.

       If the value is -1, (the default), QIconView computes suitable column widths based on the

       Note that setting a grid width overrides setMaxItemWidth().

       Set this property's value with setGridX() and get this property's value with gridX().

int gridY
       This property holds the vertical grid of the icon view.

       If the value is -1, (the default), QIconView computes suitable column heights based on the

       The default is 100 pixels.

       Note that if the gridX() value is set QIconView will ignore this property.

       Set this property's value with setMaxItemWidth() and get this property's value with
       maxItemWidth().

ResizeMode resizeMode
       This property holds the resize mode of the icon view.

       This can be Fixed or Adjust. The default is Fixed. See ResizeMode.

       Set this property's value with setResizeMode() and get this property's value with
       resizeMode().

SelectionMode selectionMode
       This property holds the selection mode of the icon view.

       This can be Single (the default), Extended, Multi or NoSelection.

       Set this property's value with setSelectionMode() and get this property's value with
       selectionMode().

bool showToolTips
       This property holds whether the icon view will display a tool tip with the complete text
       for any truncated item text.

       The default is TRUE. Note that this has no effect if setWordWrapIconText() is TRUE, as it
       is by default.

       Set this property's value with setShowToolTips() and get this property's value with
       showToolTips().

bool sortDirection
       This property holds whether the sort direction for inserting new items is ascending;.

       The default is TRUE (i.e. ascending). This sort direction is only meaningful if both
       sorting() and autoArrange() are TRUE.

       To set the sort direction, use setSorting()

       Get this property's value with sortDirection().

bool sorting
       This property holds whether the icon view sorts on insertion.

       The default is FALSE, i.e. no sorting on insertion.

       To set the sorting, use setSorting().

       Get this property's value with sorting().

int spacing
       This property holds the space in pixels between icon view items.

       The default is 5 pixels.

       Negative values for spacing are illegal.

       Set this property's value with setSpacing() and get this property's value with spacing().

bool wordWrapIconText
       This property holds whether the item text will be word-wrapped if it is too long.

       The default is TRUE.

       If this property is FALSE, icon text that is too long is truncated, and an ellipsis (...)
       appended to indicate that truncation has occurred. The full text can still be seen by the
       user if they hover the mouse because the full text is shown in a tooltip; see
       setShowToolTips().

       Set this property's value with setWordWrapIconText() and get this property's value with
       wordWrapIconText().
