<hr><a name="details"></a><h2>Detailed Description</h2>
The TQIconView class provides an area with movable labelled icons.
<p>
<p> A TQIconView can display and manage a grid or other 2D layout of
labelled icons. Each labelled icon is a <a href="tqiconviewitem.html">TQIconViewItem</a>. Items
(TQIconViewItems) can be added or deleted at any time; items can be
moved within the TQIconView. Single or multiple items can be
selected. Items can be renamed in-place. TQIconView also supports
<a href="#draganddrop">drag and drop</a>.
<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="#ItemTextPos-enum">ItemTextPos</a>).
<p> The simplest way to create a TQIconView is to create a TQIconView
object and create some TQIconViewItems with the TQIconView as their
parent, set the icon view's geometry and show it.
For example:
<pre>
TQIconView *iv = new TQIconView( this );
<a href="tqdir.html">TQDir</a> dir( path, "*.xpm" );
for ( uint i = 0; i < dir.<a href="tqdir.html#count">count</a>(); i++ ) {
(void) new <a href="tqiconviewitem.html">TQIconViewItem</a>( iv, dir[i], TQPixmap( path + dir[i] ) );
}
iv-><a href="tqwidget.html#resize">resize</a>( 600, 400 );
iv-><a href="tqwidget.html#show">show</a>();
</pre>
<p> The <a href="tqiconviewitem.html">TQIconViewItem</a> call passes a pointer to the TQIconView we wish to
populate, along with the label text and a <a href="tqpixmap.html">TQPixmap</a>.
<p> When an item is inserted the TQIconView allocates a position for it.
Existing items are rearranged if <a href="#autoArrange">autoArrange</a>() is TRUE. The
default arrangement is <a href="#Arrangement-enum">LeftToRight</a> -- the TQIconView fills up
the <em>left-most</em> column from top to bottom, then moves one column
<em>right</em> and fills that from top to bottom and so on. The
arrangement can be modified with any of the following approaches:
<ul>
<li> Call <a href="#setArrangement">setArrangement</a>(), e.g. with <a href="#Arrangement-enum">TopToBottom</a> which will fill
the <em>top-most</em> row from left to right, then moves one row <em>down</em>
and fills that row from left to right and so on.
<li> Construct each TQIconViewItem using a constructor which allows
you to specify which item the new one is to follow.
<li> Call <a href="#setSorting">setSorting</a>() or <a href="#sort">sort</a>() to sort the items.
</ul>
<p> The spacing between items is set with <a href="#setSpacing">setSpacing</a>(). Items can be
laid out using a fixed grid using <a href="#setGridX">setGridX</a>() and <a href="#setGridY">setGridY</a>(); by
default the TQIconView calculates a grid dynamically. The position
of items' label text is set with <a href="#setItemTextPos">setItemTextPos</a>(). The text's
background can be set with <a href="#setItemTextBackground">setItemTextBackground</a>(). The maximum
width of an item and of its text are set with <a href="#setMaxItemWidth">setMaxItemWidth</a>()
and <a href="#setMaxItemTextLength">setMaxItemTextLength</a>(). The label text will be word-wrapped if
it is too long; this is controlled by <a href="#setWordWrapIconText">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="#setShowToolTips">setShowToolTips</a>().
<p> Items which are <a href="tqiconviewitem.html#isSelectable">selectable</a> may be selected depending on the SelectionMode;
the default is <a href="#SelectionMode-enum">Single</a>. Because TQIconView offers multiple
selection it must display <a href="focus.html#keyboard-focus">keyboard focus</a> and selection state
separately. Therefore there are functions to set the selection
state of an item (<a href="#setSelected">setSelected</a>()) and to select which item displays
keyboard focus (<a href="#setCurrentItem">setCurrentItem</a>()). When multiple items may be
selected the icon view provides a rubberband, too.
<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="tqiconviewitem.html#setKey">TQIconViewItem::setKey</a>() the new text will also
serve as the key. (See <a href="tqiconviewitem.html#setRenameEnabled">TQIconViewItem::setRenameEnabled</a>().)
<p> You can control whether users can move items themselves with
<a href="#setItemsMovable">setItemsMovable</a>().
<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 <em>icon view</em>
and then each subsequent (<a href="tqiconviewitem.html#nextItem">TQIconViewItem::nextItem</a>()) from each
<em>item</em> in turn:
<pre>
for ( <a href="tqiconviewitem.html">TQIconViewItem</a> *item = iv->firstItem(); item; item = item-><a href="tqiconviewitem.html#nextItem">nextItem</a>() )
do_something( item );
</pre>
TQIconView also provides <a href="#currentItem">currentItem</a>(). You can search for an item
using <a href="#findItem">findItem</a>() (searching by position or for label text) and
with <a href="#findFirstVisibleItem">findFirstVisibleItem</a>() and <a href="#findLastVisibleItem">findLastVisibleItem</a>(). The number
of items is returned by <a href="#count">count</a>(). An item can be removed from an
icon view using <a href="#takeItem">takeItem</a>(); to delete an item use <tt>delete</tt>. All
the items can be deleted with <a href="#clear">clear</a>().
<p> The TQIconView emits a wide range of useful signals, including
<a href="#selectionChanged">selectionChanged</a>(), <a href="#currentChanged">currentChanged</a>(), <a href="#clicked">clicked</a>(), <a href="#moved">moved</a>() and
<a href="#itemRenamed">itemRenamed</a>().
<p> <a name="draganddrop"></a>
<h3> Drag and Drop
</h3>
<a name="1"></a><p> TQIconView supports the drag and drop of items within the TQIconView
itself. It also supports the drag and drop of items out of or into
the TQIconView and drag and drop onto items themselves. The drag and
drop of items outside the TQIconView can be achieved in a simple way
with basic functionality, or in a more sophisticated way which
provides more power and control.
<p> The simple approach to dragging items out of the icon view is to
subclass TQIconView and reimplement <a href="#dragObject">TQIconView::dragObject</a>().
<p> <pre>
TQDragObject *MyIconView::dragObject()
{
return new <a href="tqtextdrag.html">TQTextDrag</a>( <a href="#currentItem">currentItem</a>()->text(), this );
}
</pre>
<p> In this example we create a <a href="tqtextdrag.html">TQTextDrag</a> object, (derived from
<a href="tqdragobject.html">TQDragObject</a>), containing the item's label and return it as the drag
object. We could just as easily have created a <a href="tqimagedrag.html">TQImageDrag</a> from the
item's pixmap and returned that instead.
<p> TQIconViews and their TQIconViewItems can also be the targets of drag
and drops. To make the TQIconView itself able to accept drops connect
to the <a href="#dropped">dropped</a>() signal. When a drop occurs this signal will be
emitted with a TQDragEvent and a <a href="tqvaluelist.html">TQValueList</a> of TQIconDragItems. To
make a <a href="tqiconviewitem.html">TQIconViewItem</a> into a drop target subclass TQIconViewItem and
reimplement <a href="tqiconviewitem.html#acceptDrop">TQIconViewItem::acceptDrop</a>() and
<a href="tqiconviewitem.html#dropped">TQIconViewItem::dropped</a>().
<p> <pre>
bool MyIconViewItem::acceptDrop( const <a href="tqmimesource.html">TQMimeSource</a> *mime ) const
{
if ( mime-><a href="tqmimesource.html#provides">provides</a>( "text/plain" ) )
return TRUE;
return FALSE;
}
void MyIconViewItem::dropped( <a href="tqdropevent.html">TQDropEvent</a> *evt, const <a href="tqvaluelist.html">TQValueList</a><TQIconDragItem>& )
{
<a href="tqstring.html">TQString</a> label;
if ( TQTextDrag::<a href="tqtextdrag.html#decode">decode</a>( evt, label ) )
setText( label );
}
</pre>
<p> See <a href="iconview-simple_dd-main-h.html">iconview/simple_dd/main.h</a> and <a href="iconview-simple_dd-main-cpp.html">iconview/simple_dd/main.cpp</a> for a simple drag and drop example
which demonstrates drag and drop between a TQIconView and a
<a href="ntqlistbox.html">TQListBox</a>.
<p> If you want to use extended drag-and-drop or have drag shapes drawn
you must take a more sophisticated approach.
<p> The first part is starting drags -- you should use a <a href="tqicondrag.html">TQIconDrag</a> (or a
class derived from it) for the drag object. In <a href="#dragObject">dragObject</a>() create the
drag object, populate it with TQIconDragItems 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 <a href="tqicondragitem.html">TQIconDragItem</a> for
each selected item, and append these items with <a href="tqicondrag.html#append">TQIconDrag::append</a>() to
the TQIconDrag object. You can use <a href="tqicondragitem.html#setData">TQIconDragItem::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
TQIconDrag, which implements additional encoding and decoding
functions.
<p> When a drag enters the icon view, there is little to do. Simply
connect to the <a href="#dropped">dropped</a>() signal and reimplement
<a href="tqiconviewitem.html#acceptDrop">TQIconViewItem::acceptDrop</a>() and <a href="tqiconviewitem.html#dropped">TQIconViewItem::dropped</a>(). If you've
used a <a href="tqicondrag.html">TQIconDrag</a> (or a subclass of it) the second argument to the
dropped signal contains a <a href="tqvaluelist.html">TQValueList</a> of TQIconDragItems -- you can
access their data by calling <a href="tqicondragitem.html#data">TQIconDragItem::data</a>() on each one.
<p> For an example implementation of complex drag-and-drop look at the
fileiconview example (qt/examples/fileiconview).
<p> <p>See also <a href="tqiconviewitem.html#setDragEnabled">TQIconViewItem::setDragEnabled</a>(), <a href="tqiconviewitem.html#setDropEnabled">TQIconViewItem::setDropEnabled</a>(), <a href="tqiconviewitem.html#acceptDrop">TQIconViewItem::acceptDrop</a>(), <a href="tqiconviewitem.html#dropped">TQIconViewItem::dropped</a>(), and <a href="advanced.html">Advanced Widgets</a>.

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Arrangement-enum"></a>TQIconView::Arrangement</h3>
<p> This enum type determines in which direction the items flow when
the view runs out of space.
<ul>
<li><tt>TQIconView::LeftToRight</tt> - Items which don't fit into the view cause the
viewport to extend vertically (you get a vertical scrollbar).
<li><tt>TQIconView::TopToBottom</tt> - Items which don't fit into the view cause the
viewport to extend horizontally (you get a horizontal scrollbar).
</ul>
<h3 class=fn><a name="ItemTextPos-enum"></a>TQIconView::ItemTextPos</h3>
<p> This enum type specifies the position of the item text in relation
to the icon.
<ul>
<li><tt>TQIconView::Bottom</tt> - The text is drawn below the icon.
<li><tt>TQIconView::Right</tt> - The text is drawn to the right of the icon.
</ul>
<h3 class=fn><a name="ResizeMode-enum"></a>TQIconView::ResizeMode</h3>
<p> This enum type is used to tell TQIconView how it should treat the
positions of its icons when the widget is resized. The modes are:
<ul>
<li><tt>TQIconView::Fixed</tt> - The icons' positions are not changed.
<li><tt>TQIconView::Adjust</tt> - The icons' positions are adjusted to be within the
new geometry, if possible.
</ul>
<h3 class=fn><a name="SelectionMode-enum"></a>TQIconView::SelectionMode</h3>
<p> This enumerated type is used by TQIconView to indicate how it
reacts to selection by the user. It has four values:
<ul>
<li><tt>TQIconView::Single</tt> - 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 <a href="#clearSelection">TQIconView::clearSelection</a>().)
<li><tt>TQIconView::Multi</tt> - 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. Also, multiple items can be selected by dragging the
mouse while the left mouse button stays pressed.
<li><tt>TQIconView::Extended</tt> - 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.
<li><tt>TQIconView::NoSelection</tt> - Items cannot be selected.
</ul><p> To summarise: <a href="#SelectionMode-enum">Single</a> is a real single-selection icon view; <a href="#SelectionMode-enum">Multi</a> a real multi-selection icon view; <a href="#SelectionMode-enum">Extended</a> 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 <a href="#SelectionMode-enum">NoSelection</a> mode is for an icon view where the user can look but
not touch.

</h3>
<p> 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.
<p> <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 using
<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 have to decode the data in <em>e</em>
and work with that.
<p> Note TQIconViewItems may be drop targets; if a drop event occurs on
an item the item handles the drop.

<p> <a href="tqiconviewitem.html#compare">TQIconViewItem::compare</a>() 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.
<p> <p>See also <a href="#autoArrange-prop">TQIconView::autoArrange</a>, <a href="#autoArrange-prop">TQIconView::autoArrange</a>, <a href="#sortDirection-prop">sortDirection</a>, <a href="#sort">sort</a>(), and <a href="tqiconviewitem.html#setKey">TQIconViewItem::setKey</a>().
<h3 class=fn>void <a name="setSpacing"></a>TQIconView::setSpacing ( int sp )<tt> [virtual]</tt>
</h3><p>Sets the space in pixels between icon view items to <em>sp</em>.
See the <a href="tqiconview.html#spacing-prop">"spacing"</a> property for details.
<h3 class=fn>void <a name="setWordWrapIconText"></a>TQIconView::setWordWrapIconText ( bool b )<tt> [virtual]</tt>
</h3><p>Sets whether the item text will be word-wrapped if it is too long to <em>b</em>.
See the <a href="tqiconview.html#wordWrapIconText-prop">"wordWrapIconText"</a> property for details.
<h3 class=fn>bool <a name="showToolTips"></a>TQIconView::showToolTips () const
</h3><p>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 <a href="tqiconview.html#showToolTips-prop">"showToolTips"</a> property for details.
<h3 class=fn>void <a name="slotUpdate"></a>TQIconView::slotUpdate ()<tt> [virtual protected slot]</tt>
</h3>
This slot is used for a slightly-delayed update.
<p> The icon view is not redrawn immediately after inserting a new item
but after a very small delay using a <a href="tqtimer.html">TQTimer</a>. 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.
<h3 class=fn>void <a name="sort"></a>TQIconView::sort ( bool ascending = TRUE )<tt> [virtual]</tt>
</h3>
Sorts and rearranges all the items in the icon view. If <em>ascending</em> is TRUE, the items are sorted in increasing order,
otherwise they are sorted in decreasing order.
<p> <a href="tqiconviewitem.html#compare">TQIconViewItem::compare</a>() 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.
<p> Note that this function sets the sort order to <em>ascending</em>.
<p> <p>See also <a href="tqiconviewitem.html#key">TQIconViewItem::key</a>(), <a href="tqiconviewitem.html#setKey">TQIconViewItem::setKey</a>(), <a href="tqiconviewitem.html#compare">TQIconViewItem::compare</a>(), <a href="#setSorting">TQIconView::setSorting</a>(), and <a href="#sortDirection-prop">TQIconView::sortDirection</a>.
<h3 class=fn>bool <a name="sortDirection"></a>TQIconView::sortDirection () const
</h3><p>Returns TRUE if the sort direction for inserting new items is ascending;; otherwise returns FALSE.
See the <a href="tqiconview.html#sortDirection-prop">"sortDirection"</a> property for details.
<h3 class=fn>bool <a name="sorting"></a>TQIconView::sorting () const
</h3><p>Returns TRUE if the icon view sorts on insertion; otherwise returns FALSE.
See the <a href="tqiconview.html#sorting-prop">"sorting"</a> property for details.
<h3 class=fn>int <a name="spacing"></a>TQIconView::spacing () const
</h3><p>Returns the space in pixels between icon view items.
See the <a href="tqiconview.html#spacing-prop">"spacing"</a> property for details.
<h3 class=fn>void <a name="startDrag"></a>TQIconView::startDrag ()<tt> [virtual protected]</tt>
</h3>
Starts a drag.
<h3 class=fn>void <a name="takeItem"></a>TQIconView::takeItem ( <a href="tqiconviewitem.html">TQIconViewItem</a> * item )<tt> [virtual]</tt>
</h3>
Takes the icon view item <em>item</em> 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
<a href="tqiconviewitem.html#~TQIconViewItem">TQIconViewItem::~TQIconViewItem</a>() calls it. The normal way to delete
an item is to delete it.
<h3 class=fn>bool <a name="wordWrapIconText"></a>TQIconView::wordWrapIconText () const
</h3><p>Returns TRUE if the item text will be word-wrapped if it is too long; otherwise returns FALSE.
See the <a href="tqiconview.html#wordWrapIconText-prop">"wordWrapIconText"</a> property for details.
