The QHeaderView class provides a header row or header column for item views.
A QHeaderView displays the headers used in item views such as the QTableView and QTreeView classes. It takes the place of Qt3's QHeader class previously used for the same purpose, but uses the Qt's model/view architecture for consistency with the item view classes.
The QHeaderView class is one of the Model/View Classes and is part of Qt's Model/View Programming{model/view framework}.
The header gets the data for each section from the model using the QAbstractItemModel::headerData() function. You can set the data by using QAbstractItemModel::setHeaderData().
Each header has an orientation() and a number of sections, given by the count() function. A section refers to a part of the header - either a row or a column, depending on the orientation.
Sections can be moved and resized using moveSection() and resizeSection(); they can also be hidden and shown with hideSection() and showSection().
Each section of a header is described by a section ID, specified by its section(), and can be located at a particular visualIndex() in the header. A section can have a sort indicator set with setSortIndicator(); this indicates whether the items in the associated item view will be sorted in the order given by the section.
For a horizontal header the section is equivalent to a column in the model, and for a vertical header the section is equivalent to a row in the model.
A header can be fixed in place, or made movable with setMovable(). It can be made clickable with setClickable(), and has resizing behavior in accordance with setResizeMode().
A header will emit sectionMoved() if the user moves a section, sectionResized() if the user resizes a section, and sectionClicked() as well as sectionHandleDoubleClicked() in response to mouse clicks. A header will also emit sectionCountChanged() and sectionAutoResize().
You can identify a section using the logicalIndex() and logicalIndexAt() functions, or by its index position, using the visualIndex() and visualIndexAt() functions. The visual index will change if a section is moved, but the logical index will not change.
QTableWidget and QTableView create default headers. If you want the headers to be visible, you can use QFrame::setVisible().
Not all Qt::ItemDataRole will have an effect on a QHeaderView. If you need to draw other roles, you can subclass QHeaderView and reimplement QHeaderView::paintEvent(). QHeaderView respects the following item data roles: Qt::TextAlignmentRole, Qt::DisplayRole, Qt::FontRole, Qt::DecorationRole, Qt::ForegroundRole, and Qt::BackgroundRole.

The resize mode specifies the behavior of the header sections.
It can be set on the entire header view or on individual sections using setResizeMode().

| void QHeaderView::setResizeMode | ( | int | logicalIndex, |
| ResizeMode | mode | ||
| ) |
Sets the constraints on how the section specified by logicalIndex in the header can be resized to those described by the given mode.
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
The logical index should exist at the time this function is called.

| void QHeaderView::setSectionHidden | ( | int | logicalIndex, |

If hide is true the section specified by logicalIndex is hidden; otherwise the section is shown.

| void QHeaderView::setSortIndicator | ( | int | logicalIndex, |
| Qt::SortOrder | order | ||
| ) |
Sets the sort indicator for the section specified by the given logicalIndex in the direction specified by order, and removes the sort indicator from any other section that was showing it.
logicalIndex may be -1, in which case no sort indicator will be shown and the model will return to its natural, unsorted order. Note that not all models support this and may even crash in this case.
