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
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: fileiconview/qfileiconview.cpp and iconview/simple_dd/main.cpp.
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: iconview/main.cpp and iconview/simple_dd/main.cpp.
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.

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 the index of item, or -1 if item doesn't exist in
this 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.

are no items in the icon view.
See also firstItem() and currentItem().
QIconViewItem * QIconView::makeRowLayout ( QIconViewItem * begin, int & y, bool & changed ) [protected]
Lays out a row of icons (if Arrangement == TopToBottom this is
a column). Starts laying out with the item begin. y is the
starting coordinate. Returns the last item of the row (column) and
sets the new starting coordinate to y. The changed parameter
is used internally.
Warning: This function may be made private in a future version of
Qt. We do not recommend calling it.

coordinate system (QMouseEvent::globalPos()).
See also rightButtonClicked() and pressed().
void QIconView::moved () [signal]
This signal is emitted after successfully dropping one (or more)
items of the icon view. If the items should be removed, it's best
to do so in a slot connected to this signal.
Example: iconview/main.cpp.
void QIconView::onItem ( QIconViewItem * item ) [signal]
This signal is emitted when the user moves the mouse cursor onto
an item, similar to the QWidget::enterEvent() function.
void QIconView::onViewport () [signal]

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]
Sets the space in pixels between icon view items to sp.
See the "spacing" property for details.

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.

int spacing
This property holds the space in pixels between icon view items.
The default is 5 pixels.
Negative values for spacing are illegal.

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

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().
