<hr><a name="details"></a><h2>Detailed Description</h2>
The QListView class implements a list/tree view.
<p>
<p> It can display and control a hierarchy of multi-column items, and
provides the ability to add new items at any time. The user may
select one or many items (depending on the <a href="#SelectionMode-enum">SelectionMode</a>) and
sort the list in increasing or decreasing order by any column.
<p> The simplest pattern 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->addColumn( "Qualified name" );
table->addColumn( "Namespace" );
</pre><pre> element = new <a href="qlistviewitem.html">QListViewItem</a>( table, qName, namespaceURI );
</pre>
<p> Further nodes can be added to the list view object (the root of the
tree) or as child nodes to QListViewItems:
<p> <pre> <a name="x2105"></a> for ( int i = 0 ; i < attributes.<a href="qxmlattributes.html#length">length</a>(); i++ ) {
<a name="x2107"></a><a name="x2106"></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:
<center><table cellpadding="4" cellspacing="2" border="0">
<tr bgcolor="#a2c511"> <th valign="top">Function <th valign="top">Action
<tr bgcolor="#f0f0f0"> <td valign="top"><a href="#addColumn">addColumn</a>()
<td valign="top">Adds a column with a text label and perhaps width. Columns
are counted from the left starting with column 0.
<tr bgcolor="#d0d0d0"> <td valign="top"><a href="#setColumnWidthMode">setColumnWidthMode</a>()
<td valign="top">Sets the column to be resized automatically or not.
<tr bgcolor="#f0f0f0"> <td valign="top"><a href="#setAllColumnsShowFocus">setAllColumnsShowFocus</a>()
<td valign="top">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
just using column 0.
<tr bgcolor="#d0d0d0"> <td valign="top"><a href="#setRootIsDecorated">setRootIsDecorated</a>()
<td valign="top">Sets whether root items should show open/close decoration to their left.
The default is FALSE.
<tr bgcolor="#f0f0f0"> <td valign="top"><a href="#setTreeStepSize">setTreeStepSize</a>()
<td valign="top">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.
<tr bgcolor="#d0d0d0"> <td valign="top"><a href="#setSorting">setSorting</a>()
<td valign="top">Sets whether the items should be sorted, whether it should
be in ascending or descending order, and by what column
they 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).
</table></center>
<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 (whether it is
on-screen or not). <a href="#firstChild">firstChild</a>() returns the list view's first item
(not necessarily visible on-screen).
<p> You can iterate over visible items using
<a href="qlistviewitem.html#itemBelow">QListViewItem::itemBelow</a>(); over a list view's top-level items
using <a href="qlistviewitem.html#firstChild">QListViewItem::firstChild</a>() and
<a href="qlistviewitem.html#nextSibling">QListViewItem::nextSibling</a>(); or every item using a
<a href="qlistviewitemiterator.html">QListViewItemIterator</a>. See
the <a href="qlistviewitem.html">QListViewItem</a> documentation for examples of traversal.
<p> An item can be moved amongst its siblings using
<a href="qlistviewitem.html#moveItem">QListViewItem::moveItem</a>(). To move an item in the hierarchy use
<a href="#takeItem">takeItem</a>() and <a href="#insertItem">insertItem</a>(). Item's (and all their child items)
are deleted with <tt>delete</tt>; to delete all the list view's items
use <a href="#clear">clear</a>().
<p> There are a variety of selection modes described in the
QListView::SelectionMode documentation. The default is <a href="#SelectionMode-enum">Single</a>
selection, which you can change using <a href="#setSelectionMode">setSelectionMode</a>().
<p> Because QListView offers multiple selection it must 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 set 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 indicates selection. The first
group consists of <a href="#selectionChanged">selectionChanged</a>() (applicable to all list
views), selectionChanged(<a href="qlistviewitem.html">QListViewItem</a>*) (applicable only to a
<a href="#SelectionMode-enum">Single</a> selection list view), and <a href="#currentChanged">currentChanged</a>(QListViewItem*).
The second group consists of <a href="#doubleClicked">doubleClicked</a>(QListViewItem*),
<a href="#returnPressed">returnPressed</a>(QListViewItem*),
<a href="#rightButtonClicked">rightButtonClicked</a>(QListViewItem*, const <a href="qpoint.html">QPoint</a>&, int), etc.
<p> Note that changing the state of the list view in a slot connected
to a list view signal may cause unexpected side effects. If you
need to change the list view's state in response to a signal, use
a <a href="qtimer.html#singleShot">single shot timer</a> with a
time out of 0, and connect this timer to a slot that modifies the
list view's state.
<p> In <a href="motif-extension.html#Motif">Motif</a> 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 <a href="#SelectionMode-enum">Single</a> (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 list view can be navigated either using the mouse or the
keyboard. Clicking a <b>-</b> icon closes an item (hides its
children) and clicking a <b>+</b> icon opens an item (shows its
children). The keyboard controls are these:
<center><table cellpadding="4" cellspacing="2" border="0">
<tr bgcolor="#a2c511"> <th valign="top">Keypress <th valign="top">Action
<tr bgcolor="#f0f0f0"> <td valign="top">Home
<td valign="top">Make the first item current and visible.
<tr bgcolor="#d0d0d0"> <td valign="top">End
<td valign="top">Make the last item current and visible.
<tr bgcolor="#f0f0f0"> <td valign="top">Page Up
<td valign="top">Make the item above the top visible item current and visible.
<tr bgcolor="#d0d0d0"> <td valign="top">Page Down
<td valign="top">Make the item below the bottom visible item current and visible.
<tr bgcolor="#f0f0f0"> <td valign="top">Up Arrow
<td valign="top">Make the item above the current item current and visible.
<tr bgcolor="#d0d0d0"> <td valign="top">Down Arrow
<td valign="top">Make the item below the current item current and visible.
<tr bgcolor="#f0f0f0"> <td valign="top">Left Arrow
<td valign="top">If the current item is closed (<b>+</b> icon) or has no
children, make its parent item current and visible. If the
current item is open (<b>-</b> 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 list view will be scrolled left.
<tr bgcolor="#d0d0d0"> <td valign="top">Right Arrow
<td valign="top">If the current item is closed (<b>+</b> icon) and has
children, the item is opened. If the current item is
opened (<b>-</b> icon) and has children the item's first
child is made current and visible. If the current item has
no children the list view is scrolled right.
</table></center>
<p> If the user starts typing letters with the focus in the list view
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.

<hr><h2>Member Type Documentation</h2>
<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>
<h3 class=fn><a name="ResizeMode-enum"></a>QListView::ResizeMode</h3>
<p> This enum describes how the list view's header adjusts to resize
events which affect the width of the list view.
<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 list view.
<li><tt>QListView::LastColumn</tt> - The last column is resized to fit the width of
the list view.
</ul>
<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.
<ul>
<li><tt>QListView::Single</tt> - When the user selects an item, any already-selected
item becomes unselected. The user can unselect the selected
item by clicking on some empty space within the view.
<li><tt>QListView::Multi</tt> - When the user selects an item in the usual way, 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>QListView::Extended</tt> - When the user selects an item in the usual 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
over them.
<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.
<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 that the column is always resized to the

<h3 class=fn><a name="QListView"></a>QListView::QListView ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 )
</h3>
Constructs a new empty list view called <em>name</em> with parent <em>parent</em>.
<p> Performance is boosted by modifying the widget flags <em>f</em> so that
only part of the <a href="qlistviewitem.html">QListViewItem</a> children is redrawn. This may be
unsuitable for custom QListViewItem classes, in which case <a href="qt.html#WidgetFlags-enum">WStaticContents</a> and <a href="qt.html#WidgetFlags-enum">WNoAutoErase</a> should be cleared.
<p> <p>See also <a href="qwidget.html#clearWFlags">QWidget::clearWFlags</a>() and <a href="qt.html#WidgetFlags-enum">Qt::WidgetFlags</a>.

<h3 class=fn><a href="qdragobject.html">QDragObject</a> * <a name="dragObject"></a>QListView::dragObject ()<tt> [virtual protected]</tt>
</h3>
If the user presses the mouse on an item and starts moving the
mouse, and the item allow dragging (see
<a href="qlistviewitem.html#setDragEnabled">QListViewItem::setDragEnabled</a>()), this function is called to get a
drag object and a drag is started unless <a href="#dragObject">dragObject</a>() returns 0.

<h3 class=fn>void <a name="dropped"></a>QListView::dropped ( <a href="qdropevent.html">QDropEvent</a> * e )<tt> [signal]</tt>
</h3>
<p> This signal is emitted, when a drop event occurred on the
viewport (not onto an item).
<p> <em>e</em> provides all the information about the drop.
<h3 class=fn>void <a name="ensureItemVisible"></a>QListView::ensureItemVisible ( const <a href="qlistviewitem.html">QListViewItem</a> * i )
</h3>
Ensures that item <em>i</em> is visible, scrolling the list view
vertically if necessary and opening (expanding) any parent items
if this is required to show the item.
<p> <p>See also <a href="#itemRect">itemRect</a>() and <a href="qscrollview.html#ensureVisible">QScrollView::ensureVisible</a>().

<p> This signal is emitted when <em>item</em> has been expanded, i.e. when
the children of <em>item</em> are shown.
<p> <p>See also <a href="#setOpen">setOpen</a>() and <a href="#collapsed">collapsed</a>().
<h3 class=fn><a href="qlistviewitem.html">QListViewItem</a> * <a name="findItem"></a>QListView::findItem ( const <a href="qstring.html">QString</a> & text, int column, ComparisonFlags compare = ExactMatch | CaseSensitive ) const
</h3>
Finds the first list view item in column <em>column</em>, that matches
<em>text</em> and returns the item, or returns 0 of no such item could
be found.
The search starts from the current item if the current item exists,
otherwise it starts from the first list view item. After reaching
the last item the search continues from the first item.
Pass OR-ed together <a href="qt.html#StringComparisonMode-enum">Qt::StringComparisonMode</a> values
in the <em>compare</em> flag, to control how the matching is performed.

</h3>
Returns the <a href="qheader.html">QHeader</a> object that manages this list view's columns.
Please don't modify the header behind the list view's back.
<p> You may safely call <a href="qheader.html#setClickEnabled">QHeader::setClickEnabled</a>(),
<a href="qheader.html#setResizeEnabled">QHeader::setResizeEnabled</a>(), <a href="qheader.html#setMovingEnabled">QHeader::setMovingEnabled</a>(),
<a href="qwidget.html#hide">QHeader::hide</a>() and all the const QHeader functions.

<h3 class=fn>void <a name="hideColumn"></a>QListView::hideColumn ( int column )
</h3>
Hides the column specified at <em>column</em>. This is a convenience
function that calls <a href="#setColumnWidth">setColumnWidth</a>( <em>column</em>, 0 ).
<p> Note: The user may still be able to resize the hidden column using
the header handles. To prevent this, call setResizeEnabled(FALSE,
<em>column</em>) on the list views header.

<h3 class=fn>void <a name="insertItem"></a>QListView::insertItem ( <a href="qlistviewitem.html">QListViewItem</a> * i )<tt> [virtual]</tt>
</h3>
Inserts item <em>i</em> into the list view as a top-level item. You do
not need to call this unless you've called <a href="#takeItem">takeItem</a>(<em>i</em>) or
<a href="qlistviewitem.html#takeItem">QListViewItem::takeItem</a>(<em>i</em>) and need to reinsert <em>i</em> elsewhere.
<p> <p>See also <a href="qlistviewitem.html#takeItem">QListViewItem::takeItem</a>() and <a href="#takeItem">takeItem</a>().
<h3 class=fn>void <a name="invertSelection"></a>QListView::invertSelection ()<tt> [virtual slot]</tt>
</h3>
Inverts the selection. Only works in <a href="#SelectionMode-enum">Multi</a> and <a href="#SelectionMode-enum">Extended</a>
selection modes.
<h3 class=fn>bool <a name="isMultiSelection"></a>QListView::isMultiSelection () const
</h3><p>Returns TRUE if the list view is in multi-selection or extended-selection mode; otherwise returns FALSE.
See the <a href="qlistview.html#multiSelection-prop">"multiSelection"</a> property for details.
<h3 class=fn>bool <a name="isOpen"></a>QListView::isOpen ( const <a href="qlistviewitem.html">QListViewItem</a> * item ) const
</h3>
Identical to <em>item</em>->isOpen(). Provided for completeness.
<p> <p>See also <a href="#setOpen">setOpen</a>().
<h3 class=fn>bool <a name="isRenaming"></a>QListView::isRenaming () const
</h3>

<h3 class=fn>bool <a name="isSelected"></a>QListView::isSelected ( const <a href="qlistviewitem.html">QListViewItem</a> * i ) const
</h3>
Returns TRUE if the list view item <em>i</em> is selected; otherwise
returns FALSE.

<h3 class=fn><a href="qlistviewitem.html">QListViewItem</a> * <a name="itemAt"></a>QListView::itemAt ( const <a href="qpoint.html">QPoint</a> & viewPos ) const
</h3>
Returns the list view item at <em>viewPos</em>. Note that <em>viewPos</em> is
in the <a href="qscrollview.html#viewport">viewport</a>()'s coordinate system, 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:
<p> <pre>
<a href="qlistviewitem.html">QListViewItem</a> *i = <a href="#itemAt">itemAt</a>( p );
if ( i ) {
if ( p.x() > header()->sectionPos( <a href="#header">header</a>()->mapToIndex( 0 ) ) +
<a href="#treeStepSize">treeStepSize</a>() * ( i-><a href="qlistviewitem.html#depth">depth</a>() + ( <a href="#rootIsDecorated">rootIsDecorated</a>() ? 1 : 0) ) + itemMargin() ||
p.x() < header()->sectionPos( <a href="#header">header</a>()->mapToIndex( 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).
<p> <p>See also <a href="#itemPos">itemPos</a>(), <a href="#itemRect">itemRect</a>(), and <a href="qscrollview.html#viewportToContents">viewportToContents</a>().
<h3 class=fn>int <a name="itemMargin"></a>QListView::itemMargin () const
</h3><p>Returns the advisory item margin that list items may use.
See the <a href="qlistview.html#itemMargin-prop">"itemMargin"</a> property for details.
<h3 class=fn>int <a name="itemPos"></a>QListView::itemPos ( const <a href="qlistviewitem.html">QListViewItem</a> * 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>().
<h3 class=fn><a href="qrect.html">QRect</a> <a name="itemRect"></a>QListView::itemRect ( const <a href="qlistviewitem.html">QListViewItem</a> * i ) const
</h3>
Returns the rectangle on the screen that item <em>i</em> occupies in
<a href="qscrollview.html#viewport">viewport</a>()'s coordinates, or an invalid rectangle if <em>i</em> is 0 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->itemRect( item ) );
r.<a href="qrect.html#setHeight">setHeight</a>( (QCOORD)(QMIN( item->totalHeight(),
listView->viewport->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.
<h3 class=fn>void <a name="itemRenamed"></a>QListView::itemRenamed ( <a href="qlistviewitem.html">QListViewItem</a> * item, int col, const <a href="qstring.html">QString</a> & text )<tt> [signal]</tt>
