PySide.QtGui.QAbstractItemView class provides the basic functionality for item view classes.
PySide.QtGui.QAbstractItemView class is the base class for every standard view that uses a PySide.QtCore.QAbstractItemModel . PySide.QtGui.QAbstractItemView is an abstract class and cannot itself be instantiated. It provides a standard interface for interoperating with models through the signals and slots mechanism, enabling subclasses to be kept up-to-date with changes to their models. This class provides standard support for keyboard and mouse navigation, viewport scrolling, item editing, and selections. The keyboard navigation implements this functionality:
| 键 | 功能 |
| 方向键 | 改变当前项并选择它。 |
| Ctrl + 方向键 | 改变当前项但不选择它。 |
| Shift + 方向键 | 更改当前项并选择它。先前选中项不会被取消选择。 |
| Ctr+Space | 切换当前项的选定。 |
| Tab/Backtab | 将当前项更改为下一/上一项。 |
| Home/End | 选择模型中的第一/最后项。 |
| Page up/Page down | 按视图中的可见行数向上/向下卷动展示行。 |
| Ctrl+A | 选择模型中的所有项。 |
注意，上表假定 selection mode 允许操作。例如，无法选择项，若选定模式为 QAbstractItemView.NoSelection .
PySide.QtGui.QAbstractItemView class is one of the 模型/视图类 且属于 Qt 的 模型/视图框架 .
The view classes that inherit PySide.QtGui.QAbstractItemView only need to implement their own view-specific functionality, such as drawing items, returning the geometry of items, finding items, etc.
PySide.QtGui.QAbstractItemView provides common slots such as PySide.QtGui.QAbstractItemView.edit() and PySide.QtGui.QAbstractItemView.setCurrentIndex() . Many protected slots are also provided, including PySide.QtGui.QAbstractItemView.dataChanged() , PySide.QtGui.QAbstractItemView.rowsInserted() , PySide.QtGui.QAbstractItemView.rowsAboutToBeRemoved() , PySide.QtGui.QAbstractItemView.selectionChanged() ，和 PySide.QtGui.QAbstractItemView.currentChanged() .
根项的返回通过 PySide.QtGui.QAbstractItemView.rootIndex() , and the current item by PySide.QtGui.QAbstractItemView.currentIndex() . To make sure that an item is visible use PySide.QtGui.QAbstractItemView.scrollTo() .
Some of PySide.QtGui.QAbstractItemView ‘s functions are concerned with scrolling, for example PySide.QtGui.QAbstractItemView.setHorizontalScrollMode() and PySide.QtGui.QAbstractItemView.setVerticalScrollMode() . To set the range of the scroll bars, you can, for example, reimplement the view's PySide.QtGui.QAbstractItemView.resizeEvent() 函数：
def resizeEvent(self, event):
horizontalScrollBar().setRange(0, realWidth - width())
...
注意，范围不更新，直到小部件被展示为止。
几个其它函数涉及选定控制；例如 PySide.QtGui.QAbstractItemView.setSelectionMode() ，和 PySide.QtGui.QAbstractItemView.setSelectionBehavior() . This class provides a default selection model to work with ( PySide.QtGui.QAbstractItemView.selectionModel() ), but this can be replaced by using PySide.QtGui.QAbstractItemView.setSelectionModel() with an instance of PySide.QtGui.QItemSelectionModel .
要完全控制项的显示和编辑，可以指定委托采用 PySide.QtGui.QAbstractItemView.setItemDelegate() .
PySide.QtGui.QAbstractItemView provides a lot of protected functions. Some are concerned with editing, for example, PySide.QtGui.QAbstractItemView.edit() ，和 PySide.QtGui.QAbstractItemView.commitData() , whilst others are keyboard and mouse event handlers.
注意
If you inherit PySide.QtGui.QAbstractItemView and intend to update the contents of the viewport, you should use viewport-> PySide.QtGui.QAbstractItemView.update() 而不是 PySide.QtGui.QWidget.update() 因为所有描绘操作都发生在视口中。

| 返回类型： | PySide.QtCore.QModelIndex |
|---|
Returns the model index of the current item.
| 参数： |

This property holds the drop action that will be used by default in QAbstractItemView::drag().
If the property is not set, the drop action is CopyAction when the supported actions support CopyAction.
| 返回类型： | PySide.QtCore.QPoint |
|---|
Returns the offset of the dirty regions in the view.
若使用 PySide.QtGui.QAbstractItemView.scrollDirtyRegion() and implement a PySide.QtGui.QAbstractScrollArea.paintEvent() in a subclass of PySide.QtGui.QAbstractItemView , you should translate the area given by the paint event with the offset returned from this function.
This function is intended to lay out the items in the view. The default implementation just calls PySide.QtGui.QAbstractItemView.updateGeometries() and updates the viewport.
| 参数： | index – PySide.QtCore.QModelIndex |
|---|
| 返回类型： | PySide.QtGui.QAbstractItemView.DragDropMode |
|---|
This property holds the drag and drop event the view will act upon.

This property holds the view's drag and drop behavior.
If its value is true , the selected data will overwrite the existing item data when dropped, while moving the data will clear the item. If its value is false , the selected data will be inserted as a new item when the data is dropped. When the data is moved, the item is removed as well.
默认值为 false , as in the PySide.QtGui.QListView and PySide.QtGui.QTreeView subclasses. In the PySide.QtGui.QTableView subclass, on the other hand, the property has been set to true .
Note: This is not intended to prevent overwriting of items. The model's implementation of flags() should do that by not returning Qt.ItemIsDropEnabled .
| 返回类型： | PySide.QtCore.bool |
|---|
This property holds whether the view supports dragging of its own items.

Editing can be forced by specifying the trigger to be QAbstractItemView.AllEditTriggers .
| 参数： | index – PySide.QtCore.QModelIndex |
|---|
Starts editing the item corresponding to the given index 若它可编辑。
Note that this function does not change the current index. Since the current index defines the next and previous items to edit, users may find that keyboard navigation does not work as expected. To provide consistent navigation behavior, call PySide.QtGui.QAbstractItemView.setCurrentIndex() before this function with the same model index.

| 参数： |
|
|---|
This slot is called when rows are inserted. The new rows are those under the given parent from start to end inclusive. The base class implementation calls fetchMore() on the model to check for more data.
Schedules a layout of the items in the view to be executed when the event processing starts.
Even if PySide.QtGui.QAbstractItemView.scheduleDelayedItemsLayout() is called multiple times before events are processed, the view will only do the layout once.

若 index is invalid (e.g., if you pass the root index), this function will do nothing.
给定 widget ‘s autoFillBackground property must be set to true, otherwise the widget's background will be transparent, showing both the model data and the item at the given index .
If index widget A is replaced with index widget B, index widget A will be deleted. For example, in the code snippet below, the PySide.QtGui.QLineEdit object will be deleted.
setIndexWidget(index, QLineEdit())
...
setIndexWidget(index, QTextEdit())
This function should only be used to display static content within the visible area corresponding to an item of data. If you want to display custom dynamic content or implement a custom editor widget, subclass PySide.QtGui.QItemDelegate 代替。
| 参数： | delegate – PySide.QtGui.QAbstractItemDelegate |
|---|
Sets the item delegate for this view and its model to delegate . This is useful if you want complete control over the editing and display of items.
任何现有委托将被移除，但不被删除。 PySide.QtGui.QAbstractItemView 未拥有所有权对于 delegate .
警告
You should not share the same instance of a delegate between views. Doing so can cause incorrect or unintuitive editing behavior since each view connected to a given delegate may receive the PySide.QtGui.QAbstractItemDelegate.closeEditor() signal, and attempt to access, modify or close an editor that has already been closed.
| 参数： |
|
|---|
Sets the given item delegate used by this view and model for the given column . All items on column will be drawn and managed by delegate instead of using the default delegate (i.e., PySide.QtGui.QAbstractItemView.itemDelegate() ).
Any existing column delegate for column will be removed, but not deleted. PySide.QtGui.QAbstractItemView 未拥有所有权对于 delegate .
注意
If a delegate has been assigned to both a row and a column, the row delegate will take precedence and manage the intersecting cell index.

Sets the given item delegate used by this view and model for the given row . All items on row will be drawn and managed by delegate instead of using the default delegate (i.e., PySide.QtGui.QAbstractItemView.itemDelegate() ).
Any existing row delegate for row will be removed, but not deleted. PySide.QtGui.QAbstractItemView 未拥有所有权对于 delegate .
注意
If a delegate has been assigned to both a row and a column, the row delegate (i.e., this delegate) will take precedence and manage the intersecting cell index.

Doing so can cause incorrect or unintuitive editing behavior since each view connected to a given delegate may receive the PySide.QtGui.QAbstractItemDelegate.closeEditor() signal, and attempt to access, modify or close an editor that has already been closed.
| 参数： | model – PySide.QtCore.QAbstractItemModel |
|---|
设置 model for the view to present.
This function will create and set a new selection model, replacing any model that was previously set with PySide.QtGui.QAbstractItemView.setSelectionModel() . However, the old selection model will not be deleted as it may be shared between several views. We recommend that you delete the old selection model if it is no longer required. This is done with the following code:
m = view->selectionModel()
view->setModel(model())
del m
If both the old model and the old selection model do not have parents, or if their parents are long-lived objects, it may be preferable to call their deleteLater() functions to explicitly delete them.
The view does not take ownership of the model unless it is the model's parent object because the model may be shared between many different views.
| 参数： | index – PySide.QtCore.QModelIndex |
|---|
Sets the root item to the item at the given index .
| 参数： |
|
|---|
| 参数： | behavior – PySide.QtGui.QAbstractItemView.SelectionBehavior |

QAbstractItemView.SelectionMode QAbstractItemView.SelectionBehavior
| 参数： | selectionModel – PySide.QtGui.QItemSelectionModel |
|---|
Sets the current selection model to the given selectionModel .
Note that, if you call PySide.QtGui.QAbstractItemView.setModel() after this function, the given selectionModel will be replaced by one created by the view.
注意
It is up to the application to delete the old selection model if it is no longer needed; i.e., if it is not being used by other views. This will happen automatically when its parent object is deleted. However, if it does not have a parent, or if the parent is a long-lived object, it may be preferable to call its deleteLater() function to explicitly delete it.
| 参数： | state – PySide.QtGui.QAbstractItemView.State |
|---|
Sets the item view's state to the given state .
