<hr><a name="details"></a><h2>Detailed Description</h2>


The QListView class implements a list/tree view.


<p> It can display and control a hierarchy of multi-column items, and
provides the ability to add new items at any time. Among others the user
may select one or many items and sort the list in increasing or decreasing
order by any column.
<p> The simplest mode of use is to create a QListView, add some column
headers using <a href="#addColumn">addColumn</a>() and create one or more <a href="qlistviewitem.html">QListViewItem</a> or
<a href="qchecklistitem.html">QCheckListItem</a> objects with the QListView as parent:
<p> 

<pre>        QListView * table;
</pre>

<pre>        table-&gt;addColumn( "Qualified name" );
        table-&gt;addColumn( "Namespace" );
</pre><pre>            element = new <a href="qlistviewitem.html">QListViewItem</a>( table, qName, namespaceURI );
</pre>
<p> Further nodes can be added to the listview object (the root of the
tree) or as child nodes to QListViewItems:
<p> <pre>    <a name="x9"></a>        for ( int i = 0 ; i &lt; attributes.<a href="qxmlattributes.html#length">length</a>(); i++ ) {
    <a name="x11"></a><a name="x10"></a>            new <a href="qlistviewitem.html">QListViewItem</a>( element, attributes.<a href="qxmlattributes.html#qName">qName</a>(i), attributes.<a href="qxmlattributes.html#uri">uri</a>(i) );
            }
</pre>
<p> (From
<a href="tagreader-with-features-example.html">xml/tagreader-with-features/structureparser.cpp</a> )
<p> The main setup functions are
<ul>
<li> <a href="#addColumn">addColumn</a>() - adds a column with text and perhaps width.
<p> <li> <a href="#setColumnWidthMode">setColumnWidthMode</a>() - sets the column to be resized
automatically or not.
<p> <li> <a href="#setAllColumnsShowFocus">setAllColumnsShowFocus</a>() - sets whether items should show
<a href="focus.html#keyboard-focus">keyboard focus</a> using all columns or just column 0.  The default is
to show focus using just column 0.
<p> <li> <a href="#setRootIsDecorated">setRootIsDecorated</a>() - sets whether root items can be opened
and closed by the user and have open/close decoration to their left.
The default is FALSE.
<p> <li> <a href="#setTreeStepSize">setTreeStepSize</a>() - sets how many pixels an item's
children are indented relative to their parent.  The default is 20.
This is mostly a matter of taste.
<p> <li> <a href="#setSorting">setSorting</a>() - sets whether the items should be sorted,
whether it should be in ascending or descending order, and by what
column it should be sorted. By default the list view is sorted by
the first column; to switch this off call <a href="#setSorting">setSorting</a>( -1 ).
</ul>
<p> To handle events such as mouse presses on the list view, derived classes
can reimplement the <a href="qscrollview.html">QScrollView</a> functions
<a href="qscrollview.html#contentsMousePressEvent">contentsMousePressEvent</a>,
<a href="qscrollview.html#contentsMouseReleaseEvent">contentsMouseReleaseEvent</a>,
<a href="qscrollview.html#contentsMouseDoubleClickEvent">contentsMouseDoubleClickEvent</a>,
<a href="qscrollview.html#contentsMouseMoveEvent">contentsMouseMoveEvent</a>,
<a href="qscrollview.html#contentsDragEnterEvent">contentsDragEnterEvent</a>,
<a href="qscrollview.html#contentsDragMoveEvent">contentsDragMoveEvent</a>,
<a href="qscrollview.html#contentsDragLeaveEvent">contentsDragLeaveEvent</a>,
<a href="qscrollview.html#contentsDropEvent">contentsDropEvent</a>, and
<a href="qscrollview.html#contentsWheelEvent">contentsWheelEvent</a>.
<p> There are also several functions for mapping between items and
coordinates.  <a href="#itemAt">itemAt</a>() returns the item at a position on-screen,
<a href="#itemRect">itemRect</a>() returns the rectangle an item occupies on the screen, and
<a href="#itemPos">itemPos</a>() returns the position of any item (not on-screen in the
list view).  <a href="#firstChild">firstChild</a>() returns the item at the top of the view
(not necessarily on-screen) so you can iterate over the items using
either <a href="qlistviewitem.html#itemBelow">QListViewItem::itemBelow</a>() or a combination of
<a href="qlistviewitem.html#firstChild">QListViewItem::firstChild</a>() and <a href="qlistviewitem.html#nextSibling">QListViewItem::nextSibling</a>().
<p> If you need to move a list view item you can use <a href="#takeItem">takeItem</a>() and
<a href="#insertItem">insertItem</a>(). Item's are deleted with delete; to delete all items
use <a href="#clear">clear</a>(). See the <a href="qlistviewitem.html">QListViewItem</a> documentation for examples of
traversal.
<p> There are a variety of selection modes described in the
QListView::SelectionMode documentation. The default is
Single selection, which you can change using <a href="#setSelectionMode">setSelectionMode</a>().
<p> Because QListView offers multiple selection it has to display keyboard
focus and selection state separately.  Therefore there are functions
both 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>()).
<p> QListView emits two groups of signals; one group signals changes in
selection/focus state and one signals selection.  The first group
consists of <a href="#selectionChanged">selectionChanged</a>() (applicable to all list views),
selectionChanged( QListViewItem * ) (applicable only to Single
selection list view), and <a href="#currentChanged">currentChanged</a>( QListViewItem * ). The
second group consists of <a href="#doubleClicked">doubleClicked</a>( <a href="qlistviewitem.html">QListViewItem</a> * ),
<a href="#returnPressed">returnPressed</a>( QListViewItem * ) and <a href="#rightButtonClicked">rightButtonClicked</a>(
QListViewItem *, const <a href="qpoint.html">QPoint</a>&, int ), etc.
<p> In Motif style, QListView deviates fairly strongly from the look and
feel of the Motif hierarchical tree view.  This is done mostly to
provide a usable keyboard interface and to make the list view look
better with a white background.
<p> If <a href="#selectionMode">selectionMode</a>() is Single (the default) the user can select one
item at a time, e.g. by clicking an item with the mouse, see
<a href="#SelectionMode-enum">QListView::SelectionMode</a> for details.
<p> The listview can be navigated either using the mouse or the
keyboard. Clicking an <em>-</em> icon closes an item (hides its
children) and clicking an <em>+</em> icon opens an item (shows its
children). The keyboard controls are these:
<ul>
<li> <em>Home</em> - Make the first item current and visible.
<li> <em>End</em> - Make the last item current and visible.
<li> <em>Page Up</em> - Make the item above the top visible item current
and visible.
<li> <em>Page Down</em> - Make the item below the bottom visible item current
and visible.
<li> <em>Up Arrow</em> - Make the item above the current item current and
visible.
<li> <em>Down Arrow</em> - Make the item below the current item current and
visible.
<li> <em>Left Arrow</em> - If the current item is closed (<em>+</em> icon) or has
no children make its parent item current and visible. If the
current item is open (<em>-</em> icon) close it, i.e. hide its children.
Exception: if the current item is the first item and is closed and
the horizontal scrollbar is offset to the right the listview will
be scrolled left.
<li> <em>Right Arrow</em> - If the current item is closed (<em>+</em> icon) and
has children the item is opened. If the current item is opened (<em>-</em> icon) and has children the item's first child is made current and
visible. If the current item has no children the listview is
scrolled right.
</ul>
If the user starts typing letters with the focus in the listview an
incremental search will occur. For example if the user types 'd'
the current item will change to the first item that begins with the
letter 'd'; if they then type 'a', the current item will change to
the first item that begins with 'da', and so on. If no item begins
with the letters they type the current item doesn't change.
<p> <b>Warning:</b> The list view assumes ownership of all list view items
and will delete them when it does not need them any more.

<h3 class=fn><a name="RenameAction-enum"></a>QListView::RenameAction</h3> 
<p> This enum describes whether a rename operation is accepted if the
rename editor loses focus without the user pressing Enter.
<ul>
<li><tt>QListView::Accept</tt> - Rename if Enter is pressed or focus is lost.
<li><tt>QListView::Reject</tt> - Discard the rename operation if focus is lost (and
Enter has not been pressed).
</ul><p> 
<h3 class=fn><a name="ResizeMode-enum"></a>QListView::ResizeMode</h3> 
<p> This enum describes how the header adjusts to resize events which
affect the width of the listview.
<ul>
<li><tt>QListView::NoColumn</tt> - The columns do not get resized in resize events.
<li><tt>QListView::AllColumns</tt> - All columns are resized equally to fit the width
of the listview.
<li><tt>QListView::LastColumn</tt> - The last columns is resized to fit the with of the
listview.
</ul><p> 
<h3 class=fn><a name="SelectionMode-enum"></a>QListView::SelectionMode</h3> 
<p> This enumerated type is used by QListView to indicate how it reacts
to selection by the user.  It has four values:
<ul>
<li><tt>QListView::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, even
though the selection may be cleared by the application programmer
using <a href="#clearSelection">QListView::clearSelection</a>().
<li><tt>QListView::Multi</tt> - When the user selects an item in the most ordinary
way, the selection status of that item is toggled and the other
items are left alone.
<li><tt>QListView::Extended</tt> - When the user selects an item in the most
ordinary way, 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. And
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>QListView::NoSelection</tt> - Items cannot be selected.
</ul><p> In other words, <a href="#SelectionMode-enum">Single</a> is a real single-selection list view, <a href="#SelectionMode-enum">Multi</a> a real multi-selection list view, <a href="#SelectionMode-enum">Extended</a> is a list view
where 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>
is a list view where the user can look but not touch.

<h3 class=fn><a name="WidthMode-enum"></a>QListView::WidthMode</h3> 
<p> This enum type describes how the width of a column in the view
changes.  The currently defined modes are:
<ul>
<li><tt>QListView::Manual</tt> - the column width does not change automatically.
<li><tt>QListView::Maximum</tt> - the column is automatically sized according to the
widths of all items in the column.  (Note: The column never shrinks
in this case.) This means the column is always resized to the
width of the item with the largest width in the column.
</ul><p> <p>See also <a href="#setColumnWidth">setColumnWidth</a>(), <a href="#setColumnWidthMode">setColumnWidthMode</a>() and <a href="#columnWidth">columnWidth</a>().

</h3>  Returns a pointer to the <a href="qlistviewitem.html">QListViewItem</a> at <em>viewPos</em>.  Note
that <em>viewPos</em> is in the coordinate system of <a href="qscrollview.html#viewport">viewport</a>(), not in
the list view's own, much larger, coordinate system.
<p> <a href="#itemAt">itemAt</a>() returns 0 if there is no such item.
<p> Note that you also get the pointer to the item if <em>viewPos</em> points
to the root decoration (see <a href="#setRootIsDecorated">setRootIsDecorated</a>()) of the item. To
check whether or not <em>viewPos</em> is on the root decoration of the
item, you can do something like this:

  <a href="qlistviewitem.html">QListViewItem</a> *i = <a href="#itemAt">itemAt</a>( p );
  if ( i ) {
      if ( p.x() &gt; header()-&gt;cellPos( <a href="#header">header</a>()-&gt;mapToActual( 0 ) ) +

          ; // p is not on root decoration
      else
          ; // p is on the root decoration
  }
  </pre>
 
<p> This might be interesting if you use this function to find out where the user
clicked and if you want to start a drag (which you do not want to do if the
user clicked onto the root decoration of an item).

</h3>  Returns the y-coordinate of <em>item</em> in the list view's
coordinate system.  This function is normally much slower than
<a href="#itemAt">itemAt</a>() but it works for all items, whereas itemAt() normally works
only for items on the screen.
<p> This is a thin wrapper around <a href="qlistviewitem.html#itemPos">QListViewItem::itemPos</a>().
<p> <p>See also <a href="#itemAt">itemAt</a>() and <a href="#itemRect">itemRect</a>().

pointer or is not currently visible.
<p> The rectangle returned does not include any children of the
rectangle (i.e. it uses <a href="qlistviewitem.html#height">QListViewItem::height</a>(), rather than
<a href="qlistviewitem.html#totalHeight">QListViewItem::totalHeight</a>()).  If you want the rectangle to include
children you can use something like this:
<p> <pre>
    <a href="qrect.html">QRect</a> r( listView-&gt;itemRect( item ) );
    r.<a href="qrect.html#setHeight">setHeight</a>( (QCOORD)(QMIN( item-&gt;totalHeight(),
                                listView-&gt;viewport-&gt;height() - r.<a href="qrect.html#y">y</a>() ) ) )
  </pre>
 
<p> Note the way it avoids too-high rectangles.  totalHeight() can be
much larger than the window system's coordinate system allows.
<p> <a href="#itemRect">itemRect</a>() is comparatively slow.  It's best to call it only for
items that are probably on-screen.
