67 \class QTreeView-
68 \brief The QTreeView class provides a default model/view implementation of a tree view.-
69-
70 \ingroup model-view-
71 \ingroup advanced-
72 \inmodule QtWidgets-
73-
74 A QTreeView implements a tree representation of items from a-
75 model. This class is used to provide standard hierarchical lists that-
76 were previously provided by the \c QListView class, but using the more-
77 flexible approach provided by Qt's model/view architecture.-
78-
79 The QTreeView class is one of the \l{Model/View Classes} and is part of-
80 Qt's \l{Model/View Programming}{model/view framework}.-
81-
82 QTreeView implements the interfaces defined by the-
83 QAbstractItemView class to allow it to display data provided by-
84 models derived from the QAbstractItemModel class.-
85-
86 It is simple to construct a tree view displaying data from a-
87 model. In the following example, the contents of a directory are-
88 supplied by a QFileSystemModel and displayed as a tree:-
89-
90 \snippet shareddirmodel/main.cpp 3-
91 \snippet shareddirmodel/main.cpp 6-
92-
93 The model/view architecture ensures that the contents of the tree view-
94 are updated as the model changes.-
95-
96 Items that have children can be in an expanded (children are-
97 visible) or collapsed (children are hidden) state. When this state-
98 changes a collapsed() or expanded() signal is emitted with the-
99 model index of the relevant item.-
100-
101 The amount of indentation used to indicate levels of hierarchy is-
102 controlled by the \l indentation property.-
103-
104 Headers in tree views are constructed using the QHeaderView class and can-
105 be hidden using \c{header()->hide()}. Note that each header is configured-
106 with its \l{QHeaderView::}{stretchLastSection} property set to true,-
107 ensuring that the view does not waste any of the space assigned to it for-
108 its header. If this value is set to true, this property will override the-
109 resize mode set on the last section in the header.-
110-
111 By default, all columns in a tree view are movable except the first. To-
112 disable movement of these columns, use QHeaderView's-
113 \l {QHeaderView::}{setSectionsMovable()} function. For more information-
114 about rearranging sections, see \l {Moving Header Sections}.-
115-
116 \section1 Key Bindings-
117-
118 QTreeView supports a set of key bindings that enable the user to-
119 navigate in the view and interact with the contents of items:-
120-
121 \table-
122 \header \li Key \li Action-
123 \row \li Up \li Moves the cursor to the item in the same column on-
124 the previous row. If the parent of the current item has no more rows to-
125 navigate to, the cursor moves to the relevant item in the last row-
126 of the sibling that precedes the parent.-
127 \row \li Down \li Moves the cursor to the item in the same column on-
128 the next row. If the parent of the current item has no more rows to-
129 navigate to, the cursor moves to the relevant item in the first row-
130 of the sibling that follows the parent.-
131 \row \li Left \li Hides the children of the current item (if present)-
132 by collapsing a branch.-
133 \row \li Minus \li Same as LeftArrow.-
134 \row \li Right \li Reveals the children of the current item (if present)-
135 by expanding a branch.-
136 \row \li Plus \li Same as RightArrow.-
137 \row \li Asterisk \li Expands all children of the current item (if present).-
138 \row \li PageUp \li Moves the cursor up one page.-
139 \row \li PageDown \li Moves the cursor down one page.-
140 \row \li Home \li Moves the cursor to an item in the same column of the first-
141 row of the first top-level item in the model.-
142 \row \li End \li Moves the cursor to an item in the same column of the last-
143 row of the last top-level item in the model.-
144 \row \li F2 \li In editable models, this opens the current item for editing.-
145 The Escape key can be used to cancel the editing process and revert-
146 any changes to the data displayed.-
147 \endtable-

162 \section1 Improving Performance-
163-
164 It is possible to give the view hints about the data it is handling in order-
165 to improve its performance when displaying large numbers of items. One approach-
166 that can be taken for views that are intended to display items with equal heights-
167 is to set the \l uniformRowHeights property to true.-
