<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>A view class that displays a model as a tree or tree table. </p>
<p>The view displays data from a <a class="el" href="classWt_1_1WAbstractItemModel.html" title="An abstract model for use with Wt's view classes.">WAbstractItemModel</a> in a tree or tree table. It provides incremental rendering, allowing the display of data models of any size efficiently, without excessive use of client- or serverside resources.</p>
<p>The rendering (and editing) of items is handled by a <a class="el" href="classWt_1_1WAbstractItemDelegate.html" title="Abstract delegate class for rendering an item in an item view.">WAbstractItemDelegate</a>, by default it uses <a class="el" href="classWt_1_1WItemDelegate.html" title="Standard delegate class for rendering a view item.">WItemDelegate</a> which renders data of all predefined roles (see also <a class="el" href="group__modelview.html#ga0ae864e12320f9f89172735e075ed068" title="Enumeration that indicates a role for a data item.">Wt::ItemDataRole</a>), including text, icons, checkboxes, and tooltips.</p>
<p>The view may support editing of items, if the model indicates support (see the <a class="el" href="group__modelview.html#gga1d77c4de293aebfacbdde124de06b8b0a8664c482d721bbcb73539a924c7a9fab" title="Item can be edited.">Wt::ItemIsEditable</a> flag). You can define triggers that initiate editing of an item using <a class="el" href="classWt_1_1WAbstractItemView.html#a93d2efc8642a6b9c55b35b7665a13da5" title="Configures what actions should trigger editing.">setEditTriggers()</a>. The actual editing is provided by the item delegate (you can set an appropriate delegate for one column using <a class="el" href="classWt_1_1WAbstractItemView.html#a574bc36ec752012ba4a613e0e11e064e" title="Sets the delegate for a column.">setItemDelegateForColumn()</a>). Using <a class="el" href="classWt_1_1WAbstractItemView.html#a9a5506e031a514696c4050ccc1521b6c" title="Configures editing options.">setEditOptions()</a> you can customize if and how the view deals with multiple editors.</p>
<p>By default, all but the first columns are given a width of 150px, and the first column takes the remaining size. <b>Note that this may have as consequence that the first column's size is reduced to 0.</b> Column widths of all columns, including the first column, can be set through the API method <a class="el" href="classWt_1_1WTreeView.html#a33ba5111945bc0ec4745a536d52adec5" title="Sets the column width.">setColumnWidth()</a>, and also by the user using handles provided in the header.</p>
<p>Optionally, the treeview may be configured so that the first column is always visible while scrolling through the other columns, which may be convenient if you wish to display a model with many columns. Use <a class="el" href="classWt_1_1WAbstractItemView.html#a714e455f9881ef17b779713f6bba295a" title="Configures whether horizontal scrolling includes the first column (deprecated)">setColumn1Fixed()</a> to enable this behaviour.</p>
<p>If the model supports sorting (<a class="el" href="classWt_1_1WAbstractItemModel.html#a133931424d4daa8422bcdea911cda713" title="Sorts the model according to a particular column.">WAbstractItemModel::sort()</a>), such as the <a class="el" href="classWt_1_1WStandardItemModel.html" title="A standard data model, which stores its data in memory.">WStandardItemModel</a>, then you can enable sorting buttons in the header, using <a class="el" href="classWt_1_1WAbstractItemView.html#ae1c86a0f37f97f63aed3b00fd8ffad7c" title="Enables or disables sorting for all columns.">setSortingEnabled()</a>.</p>
<p>You can allow selection on row or item level (using <a class="el" href="classWt_1_1WAbstractItemView.html#ad59b47cf9a1c5a65c5adc3e1900ceb5c" title="Changes the selection behaviour.">setSelectionBehavior()</a>), and selection of single or multiple items (using <a class="el" href="classWt_1_1WAbstractItemView.html#af6fcd9761e2f7a3b497d3563c849d320" title="Sets the selection mode.">setSelectionMode()</a>), and listen for changes in the selection using the <a class="el" href="classWt_1_1WAbstractItemView.html#ada37ffbe2d470dd227c8714645f150f0" title="Signal emitted when the selection is changed.">selectionChanged()</a> signal.</p>
<p>You may enable drag & drop support for this view, whith awareness of the items in the model. When enabling dragging (see <a class="el" href="classWt_1_1WAbstractItemView.html#a0ca99b835708d990b90000917045738e" title="Enables the selection to be dragged (drag & drop).">setDragEnabled()</a>), the current selection may be dragged, but only when all items in the selection indicate support for dragging (controlled by the <a class="el" href="group__modelview.html#gga1d77c4de293aebfacbdde124de06b8b0a2b0edddfd15d67a84723c9043479ced1">ItemIsDragEnabled</a> flag), and if the model indicates a mime-type (controlled by <a class="el" href="classWt_1_1WAbstractItemModel.html#a4c62d2cc18d133d7926a91b4f2eebe62" title="Returns a mime-type for dragging a set of indexes.">WAbstractItemModel::mimeType()</a>). Likewise, by enabling support for dropping (see <a class="el" href="classWt_1_1WAbstractItemView.html#a1eda46c8e9a21af7f6281e7096af8fbe" title="Enables drop operations (drag & drop).">setDropsEnabled()</a>), the treeview may receive a drop event on a particular item, at least if the item indicates support for drops (controlled by the <a class="el" href="group__modelview.html#gga1d77c4de293aebfacbdde124de06b8b0a95d23063251001545d4bfab1308879a3">ItemIsDropEnabled</a> flag).</p>
<p>You may also react to mouse click events on any item, by connecting to one of the <a class="el" href="classWt_1_1WAbstractItemView.html#a3b72d5f8e5b0afdea83e224354d3e91b" title="Signal emitted when an item is clicked.">clicked()</a> or <a class="el" href="classWt_1_1WAbstractItemView.html#a14ac099f58621d66834aa5674ea8ecb5" title="Signal emitted when an item is double clicked.">doubleClicked()</a> signals.</p>
<p>Usage example: </p>
<div class="fragment"><pre class="fragment"> <span class="comment">// WTreeView will display the data of a model</span>
<a class="code" href="classWt_1_1WAbstractItemModel.html" title="An abstract model for use with Wt's view classes.">Wt::WAbstractItemModel</a> *model = ...

</pre></div><h3>Graceful degradation</h3>
<p>The view provides a virtual scrolling behavior which relies on Ajax availability. When Ajax is not available, a page navigation bar is used instead, see <a class="el" href="classWt_1_1WAbstractItemView.html#a22303f489d5081d70b5bb8e8ff059948" title="Returns a page navigation widget.">createPageNavigationBar()</a>. In that case, the widget needs to be given an explicit height using <a class="el" href="classWt_1_1WTreeView.html#a482314306c8404d7ed941fd986e32623" title="Resizes the widget.">resize()</a> which determines the number of rows that are displayed at a time.</p>
<h3>CSS</h3>
<p>The treeview is styled by the current CSS theme. The look can be overridden using the <code>Wt-treeview</code> CSS class and the following selectors.</p>
