<hr><a name="details"></a><h2>Detailed Description</h2>
The TQIconViewItem class provides a single item in a <a href="tqiconview.html">TQIconView</a>.
<p>
<p> A TQIconViewItem contains an icon, a string and optionally a sort
key, and can display itself in a TQIconView.
The class is designed to be very similar to <a href="ntqlistview.html">TQListView</a> and <a href="ntqlistbox.html">TQListBox</a>
in use, both via instantiation and subclassing.
<p> The simplest way to create a TQIconViewItem and insert it into a
TQIconView is to construct the item passing the constructor a
pointer to the icon view, a string and an icon:
<p> <pre>
(void) new TQIconViewItem(
iconView, // A pointer to a TQIconView
"This is the text of the item",
aPixmap );
</pre>
<p> By default the text of an icon view item may not be edited by the
user but calling <a href="#setRenameEnabled">setRenameEnabled</a>(TRUE) will allow the user to
perform in-place editing of the item's text.
<p> When the icon view is deleted all items in it are deleted
automatically.
<p> The <a href="tqiconview.html#firstItem">TQIconView::firstItem</a>() and <a href="#nextItem">TQIconViewItem::nextItem</a>() functions
provide a means of iterating over all the items in a TQIconView:
<p> <pre>
TQIconViewItem *item;
for ( item = iconView->firstItem(); item; item = item-><a href="#nextItem">nextItem</a>() )
do_something_with( item );
</pre>
<p> The item's icon view is available from <a href="#iconView">iconView</a>(), and its
position in the icon view from <a href="#index">index</a>().
<p> The item's selection status is available from <a href="#isSelected">isSelected</a>() and is
set and controlled by <a href="#setSelected">setSelected</a>() and <a href="#isSelectable">isSelectable</a>().
<p> The text and icon can be set with <a href="#setText">setText</a>() and <a href="#setPixmap">setPixmap</a>() and
retrieved with <a href="#text">text</a>() and <a href="#pixmap">pixmap</a>(). The item's sort key defaults
to text() but may be set with <a href="#setKey">setKey</a>() and retrieved with <a href="#key">key</a>().
The comparison function, <a href="#compare">compare</a>() uses key().
<p> Items may be repositioned with <a href="#move">move</a>() and <a href="#moveBy">moveBy</a>(). An item's
geometry is available from <a href="#rect">rect</a>(), <a href="#x">x</a>(), <a href="#y">y</a>(), <a href="#width">width</a>(), <a href="#height">height</a>(),
<a href="#size">size</a>(), <a href="#pos">pos</a>(), <a href="#textRect">textRect</a>() and <a href="#pixmapRect">pixmapRect</a>(). You can also test
against the position of a point with <a href="#contains">contains</a>() and <a href="#intersects">intersects</a>().
<p> To remove an item from an icon view, just delete the item. The
TQIconViewItem destructor removes it cleanly from its icon view.
<p> Because the icon view is designed to use drag-and-drop, the icon
view item also has functions for drag-and-drop which may be
reimplemented.
<p> <a name="pixmap-size-limit"></a>
<b>Note:</b> Pixmaps with individual dimensions larger than 300 pixels may
not be displayed properly, depending on the <a href="tqiconview.html#Arrangement-enum">arrangement in use</a>. For example, pixmaps wider than 300 pixels
will not be arranged correctly if the icon view uses a
<a href="tqiconview.html#Arrangement-enum">TQIconView::TopToBottom</a> arrangement, and pixmaps taller than 300 pixels
will not be arranged correctly if the icon view uses a
<a href="tqiconview.html#Arrangement-enum">TQIconView::LeftToRight</a> arrangement.

<h3 class=fn>bool <a name="acceptDrop"></a>TQIconViewItem::acceptDrop ( const <a href="tqmimesource.html">TQMimeSource</a> * mime ) const<tt> [virtual]</tt>
</h3>
<p> Returns TRUE if you can drop things with a <a href="tqmimesource.html">TQMimeSource</a> of <em>mime</em>
onto this item; otherwise returns FALSE.
<p> The default implementation always returns FALSE. You must subclass
TQIconViewItem and reimplement <a href="#acceptDrop">acceptDrop</a>() to accept drops.
<p>Examples: <a href="fileiconview-example.html#x836">fileiconview/tqfileiconview.cpp</a> and <a href="simple_dd-example.html#x2822">iconview/simple_dd/main.cpp</a>.
<h3 class=fn>void <a name="calcRect"></a>TQIconViewItem::calcRect ( const <a href="tqstring.html">TQString</a> & text_ = TQString::null )<tt> [virtual protected]</tt>
</h3>
This virtual function is responsible for calculating the
rectangles returned by <a href="#rect">rect</a>(), <a href="#textRect">textRect</a>() and <a href="#pixmapRect">pixmapRect</a>().
setRect(), <a href="#setTextRect">setTextRect</a>() and <a href="#setPixmapRect">setPixmapRect</a>() are provided mainly
for reimplementations of this function.
<p> <em>text_</em> is an internal parameter which defaults to <a href="tqstring.html#TQString-null">TQString::null</a>.
<h3 class=fn>int <a name="compare"></a>TQIconViewItem::compare ( <a href="tqiconviewitem.html">TQIconViewItem</a> * i ) const<tt> [virtual]</tt>
</h3>
Compares this icon view item to <em>i</em>. Returns -1 if this item is
less than <em>i</em>, 0 if they are equal, and 1 if this icon view item
is greater than <em>i</em>.
<p> The default implementation compares the item keys (<a href="#key">key</a>()) using
<a href="tqstring.html#localeAwareCompare">TQString::localeAwareCompare</a>(). A reimplementation may use
different values and a different comparison function. Here is a
reimplementation that uses plain Unicode comparison:
<p> <pre>
int MyIconViewItem::compare( TQIconViewItem *i ) const
{
return key().compare( i-><a href="#key">key</a>() );
}
</pre>
<p> <p>See also <a href="#key">key</a>(), <a href="tqstring.html#localeAwareCompare">TQString::localeAwareCompare</a>(), and <a href="tqstring.html#compare">TQString::compare</a>().
<h3 class=fn>bool <a name="contains"></a>TQIconViewItem::contains ( const <a href="ntqpoint.html">TQPoint</a> & pnt ) const
</h3>
Returns TRUE if the item contains the point <em>pnt</em> (in contents
coordinates); otherwise returns FALSE.
<h3 class=fn>bool <a name="dragEnabled"></a>TQIconViewItem::dragEnabled () const
</h3>
Returns TRUE if the user is allowed to drag the icon view item;
otherwise returns FALSE.
<p> <p>See also <a href="#setDragEnabled">setDragEnabled</a>().
<h3 class=fn>void <a name="dragEntered"></a>TQIconViewItem::dragEntered ()<tt> [virtual protected]</tt>
</h3>
This function is called when a drag enters the item's bounding
rectangle.
<p> The default implementation does nothing; subclasses may
reimplement this function.
<p>Example: <a href="fileiconview-example.html#x837">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn>void <a name="dragLeft"></a>TQIconViewItem::dragLeft ()<tt> [virtual protected]</tt>
</h3>
This function is called when a drag leaves the item's bounding
rectangle.
<p> The default implementation does nothing; subclasses may
reimplement this function.
<p>Example: <a href="fileiconview-example.html#x838">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn>bool <a name="dropEnabled"></a>TQIconViewItem::dropEnabled () const
</h3>
Returns TRUE if the user is allowed to drop something onto the
item; otherwise returns FALSE.
<p> <p>See also <a href="#setDropEnabled">setDropEnabled</a>().
<h3 class=fn>void <a name="dropped"></a>TQIconViewItem::dropped ( <a href="tqdropevent.html">TQDropEvent</a> * e, const <a href="tqvaluelist.html">TQValueList</a><TQIconDragItem> & lst )<tt> [virtual protected]</tt>
</h3>
<p> This function is called when something is dropped on the item. <em>e</em> provides all the information about the drop. If the drag object
of the drop was a <a href="tqicondrag.html">TQIconDrag</a>, <em>lst</em> contains the list of the
dropped items. You can get the data by calling
<a href="tqicondragitem.html#data">TQIconDragItem::data</a>() on each item. If the <em>lst</em> is empty, i.e.
the drag was not a TQIconDrag, you must decode the data in <em>e</em> and
work with that.
<p> The default implementation does nothing; subclasses may
reimplement this function.
<p>Examples: <a href="fileiconview-example.html#x839">fileiconview/tqfileiconview.cpp</a> and <a href="simple_dd-example.html#x2823">iconview/simple_dd/main.cpp</a>.

</h3>
Moves the item to position (<em>x</em>, <em>y</em>) in the icon view (these
are contents coordinates).
<h3 class=fn>bool <a name="move-2"></a>TQIconViewItem::move ( const <a href="ntqpoint.html">TQPoint</a> & pnt )<tt> [virtual]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Moves the item to the point <em>pnt</em>.
<h3 class=fn>void <a name="moveBy"></a>TQIconViewItem::moveBy ( int dx, int dy )<tt> [virtual]</tt>
</h3>
Moves the item <em>dx</em> pixels in the x-direction and <em>dy</em> pixels in
the y-direction.
<h3 class=fn>void <a name="moveBy-2"></a>TQIconViewItem::moveBy ( const <a href="ntqpoint.html">TQPoint</a> & pnt )<tt> [virtual]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Moves the item by the x, y values in point <em>pnt</em>.
<h3 class=fn><a href="tqiconviewitem.html">TQIconViewItem</a> * <a name="nextItem"></a>TQIconViewItem::nextItem () const
</h3>
Returns a pointer to the next item, or 0 if this is the last item
in the icon view.
<p> To find the first item use <a href="tqiconview.html#firstItem">TQIconView::firstItem</a>().
<p> Example:
<pre>
TQIconViewItem *item;
for ( item = iconView->firstItem(); item; item = item-><a href="#nextItem">nextItem</a>() )
do_something_with( item );
</pre>
<p> <p>See also <a href="#prevItem">prevItem</a>().
<p>Example: <a href="fileiconview-example.html#x841">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn>void <a name="paintFocus"></a>TQIconViewItem::paintFocus ( <a href="ntqpainter.html">TQPainter</a> * p, const <a href="qcolorgroup.html">TQColorGroup</a> & cg )<tt> [virtual protected]</tt>
</h3>
Paints the focus rectangle of the item using the painter <em>p</em> and
the color group <em>cg</em>.
<h3 class=fn>void <a name="paintItem"></a>TQIconViewItem::paintItem ( <a href="ntqpainter.html">TQPainter</a> * p, const <a href="qcolorgroup.html">TQColorGroup</a> & cg )<tt> [virtual protected]</tt>
</h3>
Paints the item using the painter <em>p</em> and the color group <em>cg</em>.
If you want the item to be drawn with a different font or color,
reimplement this function, change the values of the color group or
the painter's font, and then call the <a href="#paintItem">TQIconViewItem::paintItem</a>()
with the changed values.
<p>Example: <a href="fileiconview-example.html#x842">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn><a href="ntqpicture.html">TQPicture</a> * <a name="picture"></a>TQIconViewItem::picture () const<tt> [virtual]</tt>
</h3>
Returns the icon of the icon view item if it is a picture, or 0 if
it is a pixmap. In the latter case use <a href="#pixmap">pixmap</a>() instead. Normally
you set the picture of the item with <a href="#setPicture">setPicture</a>(), but sometimes
it's inconvenient to call setPicture() for every item. So you can
subclass TQIconViewItem, reimplement this function and return a
pointer to the item's picture. If you do this, you <em>must</em> call
<a href="#calcRect">calcRect</a>() manually each time the size of this picture changes.
<p> <p>See also <a href="#setPicture">setPicture</a>().
<h3 class=fn><a href="ntqpixmap.html">TQPixmap</a> * <a name="pixmap"></a>TQIconViewItem::pixmap () const<tt> [virtual]</tt>
</h3>
Returns the icon of the icon view item if it is a pixmap, or 0 if
it is a picture. In the latter case use <a href="#picture">picture</a>() instead.
Normally you set the pixmap of the item with <a href="#setPixmap">setPixmap</a>(), but
sometimes it's inconvenient to call setPixmap() for every item. So
you can subclass TQIconViewItem, reimplement this function and
return a pointer to the item's pixmap. If you do this, you <em>must</em>
call <a href="#calcRect">calcRect</a>() manually each time the size of this pixmap
changes.
<p> <p>See also <a href="#setPixmap">setPixmap</a>().
<p>Example: <a href="fileiconview-example.html#x843">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn><a href="ntqrect.html">TQRect</a> <a name="pixmapRect"></a>TQIconViewItem::pixmapRect ( bool relative = TRUE ) const
</h3>
Returns the bounding rectangle of the item's icon.
<p> If <em>relative</em> is TRUE, (the default), the rectangle is relative to
the origin of the item's rectangle. If <em>relative</em> is FALSE, the
returned rectangle is relative to the origin of the icon view's
contents coordinate system.
<p>Example: <a href="fileiconview-example.html#x844">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn><a href="ntqpoint.html">TQPoint</a> <a name="pos"></a>TQIconViewItem::pos () const

</h3>
Removes the editbox that is used for in-place renaming.
<h3 class=fn>void <a name="rename"></a>TQIconViewItem::rename ()
</h3>
Starts in-place renaming of an icon, if allowed.
<p> This function sets up the icon view so that the user can edit the
item text, and then returns. When the user is done, <a href="#setText">setText</a>() will
be called and <a href="tqiconview.html#itemRenamed">TQIconView::itemRenamed</a>() will be emitted (unless the
user canceled, e.g. by pressing the Escape key).
<p> <p>See also <a href="#setRenameEnabled">setRenameEnabled</a>().
<p>Example: <a href="fileiconview-example.html#x845">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn>bool <a name="renameEnabled"></a>TQIconViewItem::renameEnabled () const

</h3>
Repaints the item.
<h3 class=fn>int <a name="rtti"></a>TQIconViewItem::rtti () const<tt> [virtual]</tt>
</h3>
Returns 0.
<p> Make your derived classes return their own values for <a href="#rtti">rtti</a>(), so
that you can distinguish between icon view item types. You should
use values greater than 1000, preferably a large random number, to
allow for extensions to this class.
<h3 class=fn>void <a name="setDragEnabled"></a>TQIconViewItem::setDragEnabled ( bool allow )<tt> [virtual]</tt>
</h3>
If <em>allow</em> is TRUE, the icon view permits the user to drag the
icon view item either to another position within the icon view or
to somewhere outside of it. If <em>allow</em> is FALSE, the item cannot
be dragged.
<h3 class=fn>void <a name="setDropEnabled"></a>TQIconViewItem::setDropEnabled ( bool allow )<tt> [virtual]</tt>
</h3>
If <em>allow</em> is TRUE, the icon view lets the user drop something on
this icon view item.

Sets <em>icon</em> as the item's icon in the icon view. This function
might be a no-op if you reimplement <a href="#picture">picture</a>().
<p> <p>See also <a href="#picture">picture</a>().
<h3 class=fn>void <a name="setPixmap"></a>TQIconViewItem::setPixmap ( const <a href="ntqpixmap.html">TQPixmap</a> & icon )<tt> [virtual]</tt>
</h3>
Sets <em>icon</em> as the item's icon in the icon view. This function
might be a no-op if you reimplement <a href="#pixmap">pixmap</a>().
<p> <b>Note:</b> Pixmaps with individual dimensions larger than 300 pixels may

</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Sets <em>icon</em> as the item's icon in the icon view. If <em>recalc</em> is
TRUE, the icon view's layout is recalculated. If <em>redraw</em> is TRUE
(the default), the icon view is repainted.

</h3>
If <em>allow</em> is TRUE, the user can rename the icon view item by
clicking on the text (or pressing F2) while the item is selected
(in-place renaming). If <em>allow</em> is FALSE, in-place renaming is
not possible.
<p>Examples: <a href="fileiconview-example.html#x848">fileiconview/tqfileiconview.cpp</a>, <a href="iconview-example.html#x1459">iconview/main.cpp</a>, and <a href="simple_dd-example.html#x2824">iconview/simple_dd/main.cpp</a>.
<h3 class=fn>void <a name="setSelectable"></a>TQIconViewItem::setSelectable ( bool enable )<tt> [virtual]</tt>
</h3>
Sets this item to be selectable if <em>enable</em> is TRUE (the default)
or unselectable if <em>enable</em> is FALSE.
<p> The user is unable to select a non-selectable item using either
the keyboard or the mouse. (The application programmer can select
an item in code regardless of this setting.)
<p> <p>See also <a href="#isSelectable">isSelectable</a>().
<h3 class=fn>void <a name="setSelected"></a>TQIconViewItem::setSelected ( bool s, bool cb )<tt> [virtual]</tt>
</h3>
Selects or unselects the item, depending on <em>s</em>; it may also
unselect other items, depending on <a href="tqiconview.html#selectionMode">TQIconView::selectionMode</a>() and
<em>cb</em>.
<p> If <em>s</em> is FALSE, the item is unselected.
<p> If <em>s</em> is TRUE and TQIconView::selectionMode() is <tt>Single</tt>, the
item is selected and the item previously selected is unselected.
<p> If <em>s</em> is TRUE and TQIconView::selectionMode() is <tt>Extended</tt>, the
item is selected. If <em>cb</em> is TRUE, the selection state of the
other items is left unchanged. If <em>cb</em> is FALSE (the default) all
other items are unselected.
<p> If <em>s</em> is TRUE and TQIconView::selectionMode() is <tt>Multi</tt>, the
item is selected.
<p> Note that <em>cb</em> is used only if TQIconView::selectionMode() is <tt>Extended</tt>; cb defaults to FALSE.
<p> All items whose selection status changes repaint themselves.
<p>Example: <a href="fileiconview-example.html#x849">fileiconview/tqfileiconview.cpp</a>.
<h3 class=fn>void <a name="setSelected-2"></a>TQIconViewItem::setSelected ( bool s )<tt> [virtual]</tt>
