<h2>Detailed Description</h2>
223
<p>The Q3ListView class implements a list/tree view.</p>
224
<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 <tt>SelectionMode</tt>) and sort the list in increasing or decreasing order by any column.</p>
225
<p>The simplest pattern of use is to create a Q3ListView, add some column headers using <a href="q3listview.html#addColumn">addColumn</a>() and create one or more <a href="q3listviewitem.html">Q3ListViewItem</a> or <a href="q3checklistitem.html">Q3CheckListItem</a> objects with the Q3ListView as parent.</p>
226
<p>Further nodes can be added to the list view object (the root of the tree) or as child nodes to Q3ListViewItems.</p>
227
<p>The main setup functions are:</p>
228
<table align="center" cellpadding="2" cellspacing="1" border="0">
229
<tr valign="top" bgcolor="#a2c511"><th>Function</th><th>Action</th></tr>
230
<tr valign="top" bgcolor="#f0f0f0"><td><a href="q3listview.html#addColumn">addColumn</a>()</td><td>Adds a column with a text label and perhaps width. Columns are counted from the left starting with column 0.</td></tr>
231
<tr valign="top" bgcolor="#e0e0e0"><td><a href="q3listview.html#setColumnWidthMode">setColumnWidthMode</a>()</td><td>Sets the column to be resized automatically or not.</td></tr>
232
<tr valign="top" bgcolor="#f0f0f0"><td><a href="q3listview.html#allColumnsShowFocus-prop">setAllColumnsShowFocus</a>()</td><td>Sets whether items should show keyboard focus using all columns or just column 0. The default is to show focus just using column 0.</td></tr>
233
<tr valign="top" bgcolor="#e0e0e0"><td><a href="q3listview.html#rootIsDecorated-prop">setRootIsDecorated</a>()</td><td>Sets whether root items can be opened and closed by the user and have open/close decoration to their left. The default is false.</td></tr>
234
<tr valign="top" bgcolor="#f0f0f0"><td><a href="q3listview.html#treeStepSize-prop">setTreeStepSize</a>()</td><td>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.</td></tr>
235
<tr valign="top" bgcolor="#e0e0e0"><td><a href="q3listview.html#setSorting">setSorting</a>()</td><td>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 setSorting(-1).</td></tr>
237
<p>There are several functions for mapping between items and coordinates. <a href="q3listview.html#itemAt">itemAt</a>() returns the item at a position on-screen, <a href="q3listview.html#itemRect">itemRect</a>() returns the rectangle an item occupies on the screen, and <a href="q3listview.html#itemPos">itemPos</a>() returns the position of any item (whether it is on-screen or not). <a href="q3listview.html#firstChild">firstChild</a>() returns the list view's first item (not necessarily visible on-screen).</p>
238
<p>You can iterate over visible items using <a href="q3listviewitem.html#itemBelow">Q3ListViewItem::itemBelow</a>(); over a list view's top-level items using <a href="q3listviewitem.html#firstChild">Q3ListViewItem::firstChild</a>() and <a href="q3listviewitem.html#nextSibling">Q3ListViewItem::nextSibling</a>(); or every item using a <a href="q3listviewitemiterator.html">Q3ListViewItemIterator</a>. See the <a href="q3listviewitem.html">Q3ListViewItem</a> documentation for examples of traversal.</p>
239
<p>An item can be moved amongst its siblings using <a href="q3listviewitem.html#moveItem">Q3ListViewItem::moveItem</a>(). To move an item in the hierarchy use <a href="q3listview.html#takeItem">takeItem</a>() and <a href="q3listview.html#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="q3listview.html#clear">clear</a>().</p>
240
<p>There are a variety of selection modes described in the <a href="q3listview.html#SelectionMode-enum">Q3ListView::SelectionMode</a> documentation. The default is <tt>Single</tt> selection, which you can change using <a href="q3listview.html#selectionMode-prop">setSelectionMode</a>().</p>
241
<p>Because Q3ListView 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="q3listview.html#setSelected">setSelected</a>()) and to set which item displays keyboard focus (<a href="q3listview.html#setCurrentItem">setCurrentItem</a>()).</p>
242
<p>Q3ListView emits two groups of signals; one group signals changes in selection/focus state and one indicates selection. The first group consists of <a href="q3listview.html#selectionChanged">selectionChanged</a>() (applicable to all list views), selectionChanged(<a href="q3listviewitem.html">Q3ListViewItem</a>*) (applicable only to a <tt>Single</tt> selection list view), and currentChanged(<a href="q3listviewitem.html">Q3ListViewItem</a>*). The second group consists of doubleClicked(<a href="q3listviewitem.html">Q3ListViewItem</a>*), returnPressed(<a href="q3listviewitem.html">Q3ListViewItem</a>*), rightButtonClicked(<a href="q3listviewitem.html">Q3ListViewItem</a>*, const <a href="qpoint.html">QPoint</a>&, int), etc.</p>
243
<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>
244
<p>In Motif style, Q3ListView 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>
245
<p>If <a href="q3listview.html#selectionMode-prop">selectionMode</a>() is <tt>Single</tt> (the default) the user can select one item at a time, e.g. by clicking an item with the mouse, see <a href="q3listview.html#SelectionMode-enum">Q3ListView::SelectionMode</a> for details.</p>
246
<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:</p>
247
<table align="center" cellpadding="2" cellspacing="1" border="0">
248
<tr valign="top" bgcolor="#a2c511"><th>Keypress</th><th>Action</th></tr>
249
<tr valign="top" bgcolor="#f0f0f0"><td>Home</td><td>Make the first item current and visible.</td></tr>
250
<tr valign="top" bgcolor="#e0e0e0"><td>End</td><td>Make the last item current and visible.</td></tr>
251
<tr valign="top" bgcolor="#f0f0f0"><td>Page Up</td><td>Make the item above the top visible item current and visible.</td></tr>
252
<tr valign="top" bgcolor="#e0e0e0"><td>Page Down</td><td>Make the item below the bottom visible item current and visible.</td></tr>
253
<tr valign="top" bgcolor="#f0f0f0"><td>Up Arrow</td><td>Make the item above the current item current and visible.</td></tr>
254
<tr valign="top" bgcolor="#e0e0e0"><td>Down Arrow</td><td>Make the item below the current item current and visible.</td></tr>
255
<tr valign="top" bgcolor="#f0f0f0"><td>Left Arrow</td><td>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.</td></tr>
256
<tr valign="top" bgcolor="#e0e0e0"><td>Right Arrow</td><td>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.</td></tr>
258
<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>
259
<p>Note that the list view's size hint is calculated taking into account the height <i>and</i> width to produce a nice aspect ratio. This may mean that you need to reimplement <a href="q3listview.html#sizeHint">sizeHint</a>() in some cases.</p>
260
<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.</p>

546
<p>Note that you also get the pointer to the item if <i>viewPos</i> points to the root decoration (see <a href="q3listview.html#rootIsDecorated-prop">setRootIsDecorated</a>()) of the item.

547
<pre> Q3ListViewItem *i = itemAt(p);
549
if (p.x() > header()->sectionPos(header()->mapToIndex(0)) +
550
treeStepSize() * (i->depth() + (rootIsDecorated() ? 1 : 0)) + itemMargin() ||

<p>Returns the rectangle on the screen that item <i>item</i> occupies in <a href="q3scrollview.html#viewport">viewport</a>()'s coordinates, or an invalid rectangle if <i>item</i> is 0 or is not currently visible.</p>
564
<p>The rectangle returned does not include any children of the rectangle (i.e. it uses <a href="q3listviewitem.html#height">Q3ListViewItem::height</a>(), rather than <a href="q3listviewitem.html#totalHeight">Q3ListViewItem::totalHeight</a>()). If you want the rectangle to include children you can use something like this:</p>
565
<pre> QRect r(listView->itemRect(item));
566
r.setHeight(qMin(item->totalHeight(),
567
listView->viewport->height() - r.y()))</pre>
568
<p>Note the way it avoids too-high rectangles. totalHeight() can be much larger than the window system's coordinate system allows.</p>
569
<p>itemRect() is comparatively slow. It's best to call it only for items that are probably on-screen.</p>
