<hr><a name="_details"></a><h2>Detailed Description</h2>
A standard data model, which stores its data in memory.
<p>
The standard item model supports all features of <a class="el" href="classWt_1_1WAbstractItemModel.html" title="An abstract model for use with Wt's view classes.">WAbstractItemModel</a>, and can thus be used to represent tables, trees and tree tables.<p>
The data itself are organized in <a class="el" href="classWt_1_1WStandardItem.html" title="An item in a WStandardItemModel.">WStandardItem</a> objects. There is one invisible root object (<a class="el" href="classWt_1_1WStandardItemModel.html#5fdc79e8100020d98a77ad3543019477" title="Returns the invisible root item.">invisibleRootItem()</a>) that holds the toplevel data. Most methods in this class that access or manipulate data internally operate on this root item.<p>
If you want to use the model as a table, then you can use <a class="el" href="classWt_1_1WStandardItemModel.html#ef7ec1979605acf6a508989a3f93a05c" title="Creates a new standard item model with an initial geometry.">WStandardItemModel(int, int, WObject *)</a> to set the initial table size, and use the <a class="el" href="classWt_1_1WStandardItemModel.html#32d755ace793c2110b0fa5d650a0d577" title="Returns a toplevel item.">item()</a> and <a class="el" href="classWt_1_1WStandardItemModel.html#70852fa43e28b529193e9f9ffbf466b7" title="Sets a toplevel item.">setItem()</a> methods to set data. You can change the geometry by inserting rows (<a class="el" href="classWt_1_1WStandardItemModel.html#78fd43e608a944d6133d605a6093a9cf" title="Inserts a single row of top level items.">insertRow()</a>) or columns (<a class="el" href="classWt_1_1WStandardItemModel.html#e556b6aa88a3643e74cec7772901d28e" title="Inserts a single column of top level items.">insertColumn()</a>) or removing rows (<a class="el" href="classWt_1_1WAbstractItemModel.html#da64c5f4d4eba6cecab2c1e443372cb3" title="Removes one row.">removeRow()</a>) or columns (<a class="el" href="classWt_1_1WAbstractItemModel.html#7b46c63a32eb9ca9838a1a7cd5853552" title="Removes one column.">removeColumn()</a>).<p>
If you want to use the model as a tree (or tree table), then you can use the default constructor to start with an empty tree, and use the <a class="el" href="classWt_1_1WStandardItem.html" title="An item in a WStandardItemModel.">WStandardItem</a> API on <a class="el" href="classWt_1_1WStandardItemModel.html#5fdc79e8100020d98a77ad3543019477" title="Returns the invisible root item.">invisibleRootItem()</a> to manipulate the tree root. When you are building a tree, the column count at each node is 1. When you are building a tree table, you can add additional columns of data for each internal node. Only the items in the first column have children that result in a hierarchical tree structure.<p>
When using the model with a view class, you can use the <a class="el" href="classWt_1_1WStandardItemModel.html#145e32a4cbc3972eb96a4021710a8c3c" title="Returns the standard item that corresponds to a model index.">itemFromIndex()</a> and <a class="el" href="classWt_1_1WStandardItemModel.html#f12ec42f5800fce941b755e78ad12c9d" title="Returns the model index for a particular item.">indexFromItem()</a> models to translate between model indexes (that are used by the view class) and standard items.<p>
