60 \class QTreeView-
61 \brief The QTreeView class provides a default model/view implementation of a tree view.-
62-
63 \ingroup model-view-
64 \ingroup advanced-
65 \inmodule QtWidgets-
66-
67 A QTreeView implements a tree representation of items from a-
68 model. This class is used to provide standard hierarchical lists that-
69 were previously provided by the \c QListView class, but using the more-
70 flexible approach provided by Qt's model/view architecture.-
71-
72 The QTreeView class is one of the \l{Model/View Classes} and is part of-
73 Qt's \l{Model/View Programming}{model/view framework}.-
74-
75 QTreeView implements the interfaces defined by the-
76 QAbstractItemView class to allow it to display data provided by-
77 models derived from the QAbstractItemModel class.-
78-
79 It is simple to construct a tree view displaying data from a-
80 model. In the following example, the contents of a directory are-
81 supplied by a QFileSystemModel and displayed as a tree:-
82-
83 \snippet shareddirmodel/main.cpp 3-
84 \snippet shareddirmodel/main.cpp 6-
85-
86 The model/view architecture ensures that the contents of the tree view-
87 are updated as the model changes.-
88-
89 Items that have children can be in an expanded (children are-
90 visible) or collapsed (children are hidden) state. When this state-
91 changes a collapsed() or expanded() signal is emitted with the-
92 model index of the relevant item.-
93-
94 The amount of indentation used to indicate levels of hierarchy is-
95 controlled by the \l indentation property.-
96-
97 Headers in tree views are constructed using the QHeaderView class and can-
98 be hidden using \c{header()->hide()}. Note that each header is configured-
99 with its \l{QHeaderView::}{stretchLastSection} property set to true,-
100 ensuring that the view does not waste any of the space assigned to it for-
101 its header. If this value is set to true, this property will override the-
102 resize mode set on the last section in the header.-
103-
104 By default, all columns in a tree view are movable except the first. To-
105 disable movement of these columns, use QHeaderView's-
106 \l {QHeaderView::}{setSectionsMovable()} function. For more information-
107 about rearranging sections, see \l {Moving Header Sections}.-
108-
109 \section1 Key Bindings-
110-
111 QTreeView supports a set of key bindings that enable the user to-
112 navigate in the view and interact with the contents of items:-
113-
114 \table-
115 \header \li Key \li Action-
116 \row \li Up \li Moves the cursor to the item in the same column on-
117 the previous row. If the parent of the current item has no more rows to-
118 navigate to, the cursor moves to the relevant item in the last row-
119 of the sibling that precedes the parent.-
120 \row \li Down \li Moves the cursor to the item in the same column on-
121 the next row. If the parent of the current item has no more rows to-
122 navigate to, the cursor moves to the relevant item in the first row-
123 of the sibling that follows the parent.-
124 \row \li Left \li Hides the children of the current item (if present)-
125 by collapsing a branch.-
126 \row \li Minus \li Same as LeftArrow.-
127 \row \li Right \li Reveals the children of the current item (if present)-
128 by expanding a branch.-
129 \row \li Plus \li Same as RightArrow.-
130 \row \li Asterisk \li Expands all children of the current item (if present).-
131 \row \li PageUp \li Moves the cursor up one page.-
132 \row \li PageDown \li Moves the cursor down one page.-
133 \row \li Home \li Moves the cursor to an item in the same column of the first-
134 row of the first top-level item in the model.-
135 \row \li End \li Moves the cursor to an item in the same column of the last-
136 row of the last top-level item in the model.-
137 \row \li F2 \li In editable models, this opens the current item for editing.-
138 The Escape key can be used to cancel the editing process and revert-
139 any changes to the data displayed.-
140 \endtable-

142 \omit-
143 Describe the expanding/collapsing concept if not covered elsewhere.-

155 \section1 Improving Performance-
156-
157 It is possible to give the view hints about the data it is handling in order-
158 to improve its performance when displaying large numbers of items. One approach-
159 that can be taken for views that are intended to display items with equal heights-
160 is to set the \l uniformRowHeights property to true.-
