<h2>Detailed Description</h2>
<p>The Q3IconView class provides an area with movable labelled icons.</p>
<p>A Q3IconView can display and manage a grid or other 2D layout of labelled icons. Each labelled icon is a <a href="q3iconviewitem.html">Q3IconViewItem</a>. Items (Q3IconViewItems) can be added or deleted at any time; items can be moved within the Q3IconView. Single or multiple items can be selected. Items can be renamed in-place. Q3IconView also supports <a href="#draganddrop">drag and drop</a>.</p>
<p>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 <a href="q3iconview.html#ItemTextPos-enum">ItemTextPos</a>).</p>
<p>The simplest way to create a Q3IconView is to create a Q3IconView object and create some Q3IconViewItems with the Q3IconView as their parent, set the icon view's geometry and show it. For example:</p>
<pre> Q3IconView *iv = new Q3IconView(this);
QDir dir(path, "*.xpm");
for (uint i = 0; i < dir.count(); i++) {
(void) new Q3IconViewItem(iv, dir[i], QPixmap(path + dir[i]));
}
iv->resize(600, 400);
iv->show();</pre>
<p>The <a href="q3iconviewitem.html">Q3IconViewItem</a> call passes a pointer to the Q3IconView we wish to populate, along with the label text and a <a href="qpixmap.html">QPixmap</a>.</p>
<p>When an item is inserted the Q3IconView allocates a position for it. Existing items are rearranged if <a href="q3iconview.html#autoArrange-prop">autoArrange</a>() is true. The default arrangement is <a href="q3iconview.html#Arrangement-enum">LeftToRight</a> -- the Q3IconView fills up the <i>left-most</i> column from top to bottom, then moves one column <i>right</i> and fills that from top to bottom and so on. The arrangement can be modified with any of the following approaches:</p>
<ul>
<li>Call <a href="q3iconview.html#arrangement-prop">setArrangement</a>(), e.g. with <a href="q3iconview.html#Arrangement-enum">TopToBottom</a> which will fill the <i>top-most</i> row from left to right, then moves one row <i>down</i> and fills that row from left to right and so on.</li>
<li>Construct each <a href="q3iconviewitem.html">Q3IconViewItem</a> using a constructor which allows you to specify which item the new one is to follow.</li>
<li>Call <a href="q3iconview.html#setSorting">setSorting</a>() or <a href="q3iconview.html#sort">sort</a>() to sort the items.</li>
</ul>
<p>The spacing between items is set with <a href="q3iconview.html#spacing-prop">setSpacing</a>(). Items can be laid out using a fixed grid using <a href="q3iconview.html#gridX-prop">setGridX</a>() and <a href="q3iconview.html#gridY-prop">setGridY</a>(); by default the Q3IconView calculates a grid dynamically. The position of items' label text is set with <a href="q3iconview.html#itemTextPos-prop">setItemTextPos</a>(). The text's background can be set with <a href="q3iconview.html#itemTextBackground-prop">setItemTextBackground</a>(). The maximum width of an item and of its text are set with <a href="q3iconview.html#maxItemWidth-prop">setMaxItemWidth</a>() and <a href="q3iconview.html#maxItemTextLength-prop">setMaxItemTextLength</a>(). The label text will be word-wrapped if it is too long; this is controlled by <a href="q3iconview.html#wordWrapIconText-prop">setWordWrapIconText</a>(). 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 <a href="q3iconview.html#showToolTips-prop">setShowToolTips</a>().</p>
<p>Items which are <a href="q3iconviewitem.html#isSelectable">selectable</a> may be selected depending on the <a href="q3iconview.html#SelectionMode-enum">SelectionMode</a>; the default is <a href="q3iconview.html#SelectionMode-enum">Single</a>. Because Q3IconView offers multiple selection it must display keyboard focus and selection state separately. Therefore there are functions to set the selection state of an item (<a href="q3iconview.html#setSelected">setSelected</a>()) and to select which item displays keyboard focus (<a href="q3iconview.html#setCurrentItem">setCurrentItem</a>()). When multiple items may be selected the icon view provides a rubberband, too.</p>
<p>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 <a href="q3iconviewitem.html#setKey">Q3IconViewItem::setKey</a>() the new text will also serve as the key. (See <a href="q3iconviewitem.html#setRenameEnabled">Q3IconViewItem::setRenameEnabled</a>().)</p>
<p>You can control whether users can move items themselves with <a href="q3iconview.html#itemsMovable-prop">setItemsMovable</a>().</p>
<p>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 <i>icon view</i> and then each subsequent (<a href="q3iconviewitem.html#nextItem">Q3IconViewItem::nextItem</a>()) from each <i>item</i> in turn:</p>
<pre> for (Q3IconViewItem *item = iv->firstItem(); item; item = item->nextItem())
do_something(item);</pre>
<p>Q3IconView also provides <a href="q3iconview.html#currentItem">currentItem</a>(). You can search for an item using <a href="q3iconview.html#findItem">findItem</a>() (searching by position or for label text) and with <a href="q3iconview.html#findFirstVisibleItem">findFirstVisibleItem</a>() and <a href="q3iconview.html#findLastVisibleItem">findLastVisibleItem</a>(). The number of items is returned by <a href="q3iconview.html#count-prop">count</a>(). An item can be removed from an icon view using <a href="q3iconview.html#takeItem">takeItem</a>(); to delete an item use <tt>delete</tt>. All the items can be deleted with <a href="q3iconview.html#clear">clear</a>().</p>
<p>The Q3IconView emits a wide range of useful signals, including <a href="q3iconview.html#selectionChanged">selectionChanged</a>(), <a href="q3iconview.html#currentChanged">currentChanged</a>(), <a href="q3iconview.html#clicked">clicked</a>(), <a href="q3iconview.html#moved">moved</a>() and <a href="q3iconview.html#itemRenamed">itemRenamed</a>().</p>
<a name="draganddrop"></a><a name="drag-and-drop"></a>
<h3>Drag and Drop</h3>
<p>Q3IconView supports the drag and drop of items within the Q3IconView itself. It also supports the drag and drop of items out of or into the Q3IconView and drag and drop onto items themselves. The drag and drop of items outside the Q3IconView can be achieved in a simple way with basic functionality, or in a more sophisticated way which provides more power and control.</p>
<p>The simple approach to dragging items out of the icon view is to subclass Q3IconView and reimplement <a href="q3iconview.html#dragObject">Q3IconView::dragObject</a>().</p>
<pre> Q3DragObject *MyIconView::dragObject()
{
return new Q3TextDrag(currentItem()->text(), this);
}</pre>
<p>In this example we create a <a href="q3textdrag.html">Q3TextDrag</a> object, (derived from <a href="q3dragobject.html">Q3DragObject</a>), containing the item's label and return it as the drag object. We could just as easily have created a <a href="q3imagedrag.html">Q3ImageDrag</a> from the item's pixmap and returned that instead.</p>
<p>Q3IconViews and their Q3IconViewItems can also be the targets of drag and drops. To make the Q3IconView itself able to accept drops connect to the <a href="q3iconview.html#dropped">dropped</a>() signal. When a drop occurs this signal will be emitted with a QDragEvent and a <a href="qlinkedlist.html">QLinkedList</a> of Q3IconDragItems. To make a <a href="q3iconviewitem.html">Q3IconViewItem</a> into a drop target subclass <a href="q3iconviewitem.html">Q3IconViewItem</a> and reimplement <a href="q3iconviewitem.html#acceptDrop">Q3IconViewItem::acceptDrop</a>() and <a href="q3iconviewitem.html#dropped">Q3IconViewItem::dropped</a>().</p>
<pre> bool MyIconViewItem::acceptDrop(const QMimeSource *mime) const
{
if (mime->provides("text/plain"))
return true;
return false;
}
void MyIconViewItem::dropped(QDropEvent *evt, const Q3ValueList<Q3IconDragItem>&)
{
QString label;
if (Q3TextDrag::decode(evt, label))
setText(label);
}</pre>
<p>If you want to use extended drag-and-drop or have drag shapes drawn you must take a more sophisticated approach.</p>
<p>The first part is starting drags -- you should use a <a href="q3icondrag.html">Q3IconDrag</a> (or a class derived from it) for the drag object. In <a href="q3iconview.html#dragObject">dragObject</a>() create the drag object, populate it with Q3IconDragItems and return it. Normally such a drag should offer each selected item's data. So in <a href="q3iconview.html#dragObject">dragObject</a>() you should iterate over all the items, and create a <a href="q3icondragitem.html">Q3IconDragItem</a> for each selected item, and append these items with <a href="q3icondrag.html#append">Q3IconDrag::append</a>() to the <a href="q3icondrag.html">Q3IconDrag</a> object. You can use <a href="q3icondragitem.html#setData">Q3IconDragItem::setData</a>() 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 <a href="q3icondrag.html">Q3IconDrag</a>, which implements additional encoding and decoding functions.</p>
<p>When a drag enters the icon view, there is little to do. Simply connect to the <a href="q3iconview.html#dropped">dropped</a>() signal and reimplement <a href="q3iconviewitem.html#acceptDrop">Q3IconViewItem::acceptDrop</a>() and <a href="q3iconviewitem.html#dropped">Q3IconViewItem::dropped</a>(). If you've used a <a href="q3icondrag.html">Q3IconDrag</a> (or a subclass of it) the second argument to the dropped signal contains a <a href="qlinkedlist.html">QLinkedList</a> of Q3IconDragItems -- you can access their data by calling <a href="q3icondragitem.html#data">Q3IconDragItem::data</a>() on each one.</p>
<p>For an example implementation of complex drag-and-drop look at the fileiconview example (qt/examples/fileiconview).</p>
<p>See also <a href="q3iconviewitem.html#setDragEnabled">Q3IconViewItem::setDragEnabled</a>(), <a href="q3iconviewitem.html#setDropEnabled">Q3IconViewItem::setDropEnabled</a>(), <a href="q3iconviewitem.html#acceptDrop">Q3IconViewItem::acceptDrop</a>(), and <a href="q3iconviewitem.html#dropped">Q3IconViewItem::dropped</a>().</p>

<p>Takes the icon view item <i>item</i> 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 Q3IconViewItem::~Q3IconViewItem() calls it. The normal way to delete an item is to delete it.</p>
