Detailed Description

A hierarchical tree-like model of checkable items.

After construction, the structure remains fixed; The only part of state that can be modified by the user is the checked/unchecked state of items.

Constructor & Destructor Documentation

SimShell::Gui::CheckableTreeModel::CheckableTreeModel	(	const boost::property_tree::ptree &	tree,
		QObject *	parent = `nullptr`
	)

Create model.

The items are constructed from a ptree with the following structure:

<some_item0>
        <checked>false</checked>
        <children>
                <some_item1>
                        <checked>true</checked>
                </some_item1>
        </children>
</some_item0>
<some_item2>
        <checked>true</checked>
        <children/>
</some_other_item2>

The <checked> node must be present for every item, the <children> node is optional.

At a later moment, the checked/unchecked state of items can be retrieved by the method ToPTree(). The returned ptree will have the same structure, only the (boolean) values in the <checked> nodes may differ.

Parameters

tree	A Ptree of form discussed above.
parent	Qt parent object that will take ownership of this object.

Exceptions

ptree_bad_path	if malformed ptree.
ptree_bad_data	if malformed ptree.
