5 碰撞测试

**QGraphicsScene**

QList<QGraphicsItem *> QGraphicsScene::collidingItems(const QGraphicsItem *item, Qt::ItemSelectionMode mode = Qt::IntersectsItemShape) const;

QGraphicsItem
    virtual bool QGraphicsItem::collidesWithItem(const QGraphicsItem *other, Qt::ItemSelectionMode mode = Qt::IntersectsItemShape) const;

virtual bool QGraphicsItem::collidesWithPath(const QPainterPath &path, Qt::ItemSelectionMode mode = Qt::IntersectsItemShape) const;

QList<QGraphicsItem *> QGraphicsItem::collidingItems(Qt::ItemSelectionMode mode = Qt::IntersectsItemShape) const;

**6 QGraphicsView - 总共有五种模式**

view.setViewportUpdateMode(QGraphicsView::BoundingRectViewportUpdate);

**总共有五种模式，很容易理解：**  
QGraphicsView::FullViewportUpdate 全视口更新，整体都更新的意思啦  
QGraphicsView::MinimalViewportUpdate 最小更新，哪里有变动更新哪里  
QGraphicsView::SmartViewportUpdate 智能选择，它要自己选  
QGraphicsView::BoundingRectViewportUpdate 来了，来了，它就是我们要注意的。  
QGraphicsView::NoViewportUpdate 不更新  
其中默认为QGraphicsView::MinimalViewportUpdate，也就是上例中我们没有进行设置的情况。事实上除了设置为FullViewportUpdate 其余四种皆会出现问题，不妨试一试。  
我们可以通过在MyView的构造函数中设置为FullViewportUpdate 的全视口更新得到我们想要的结果，但是却是以牺牲性能为代价的。

7 **setSceneRect**

小结:  
**不变性是scene 在视口的中央**.  
**x,y值将决定scene的坐标原点.**  
graphichItem 会参考scene坐标系.

**白话讲解QT中, setSceneRect**

**QGraphicsScene::setSceneRect（） 的使用**

[https://blog.csdn.net/fadbgfnbxb/article/details/88777835][https_blog.csdn.net_fadbgfnbxb_article_details_88777835]

**8 view和scene坐标转换   ？？？？setSceneRect**

**8.1 QGraphicsScene和QGraphicsView都有成员setSceneRect(),它们有什么区别**

This property holds the scene rectangle; the bounding rectangle of the scene.  
 The scene rectangle defines the extent of the scene. It is primarily used by QGraphicsView to determine the view's default scrollable area, and by QGraphicsScene to manage item indexing.  
 If unset, or if set to a null QRectF, sceneRect() will return the largest bounding rect of all items on the scene since the scene was created (i.e., a rectangle that grows when items are added to or moved in the scene, but never shrinks).

**11 图形项坐标**

*  QGraphicsItem的大多数函数都是在其局部坐标系上操作的
 *  例如一个图形项的边界矩形QGraphicsItem::boundingRect()使用局部坐标给出的，但是**QGraphicsItem::pos()是仅有的几个例外，它返回的是图形项在父项坐标系中的坐标，如果是顶层图形项，就是在场景中的坐标**

### 图形项坐标 ###

*  图形项是**局部逻辑坐标**，一般以图件的中心（0,0）为原点
 *  图形项的鼠标事件坐标使用局部坐标表示的
 *  创建自定义图形项，绘制图形项时只需考虑其局部坐标，QGraphicsScene和QGraphicsView会自动进行坐标转换
 *  **与父项的关系：**
    
     *  一个图形项的位置使其中心点在父坐标系统中的坐标，对于没有父图形项的图形项，其父对象就是场景，图形项的位置就是在场景中的坐标
     *  如果一个图形项还是其他图形项的父项，父项进行坐标变换时，子项也做同样的坐标变换
 *  **函数操作：**
    
     *  QGraphicsItem的大多数函数都是在其局部坐标系上操作的
     *  例如一个图形项的边界矩形QGraphicsItem::boundingRect()使用局部坐标给出的，但是QGraphicsItem::pos()是仅有的几个例外，它返回的是图形项在父项坐标系中的坐标，如果是顶层图形项，就是在场景中的坐标
 *      setFlag(QGraphicsItem::ItemIsSelectable, true);  -- 
        意思是可以相应item接收调用 - virtual QVariant itemChange(GraphicsItemChange change, const QVariant &value);

### 视图坐标（view） ###

*  视图坐标就是窗口界面的物理坐标，单位是像素
 *  视图坐标置于widget或视口有关，而与观察的场景无关
 *  QGraphicsView视口的左上角坐标总是(0,0)
 *  所有的鼠标事件、拖放事件的坐标首先是由视图坐标定义的，然后用户需要将这些坐标映射为场景坐标，以便和图形项交互

### 场景坐标（scene） ###

*  场景是所有图形项的基础坐标，场景坐标描述了每个顶层图形项的位置
 *  创建场景时可以定位场景矩形区的坐标范围，例如：

![20190825172758166.png][]

*  这样定义的scene是左上角坐标为(-400,-300)，宽度为800，高度为600的矩形区域，单位是像素
 *  与图形项的关系：
    
     *  每个图形项在场景里都有一个位置坐标，由函数**QGraphicsItem::scenePos()**给出
     *  还有一个图形项边界矩形，有**QGrpahicsItem::sceneBoundingRect()**函数给出。
     *  边界矩形可以使用QGraphicsScene指导场景的那个区域发生了变化。场景发生变化时会发生**QGraphicsScene::changed()信号**，参数是一个场景的矩形列表，表示发生变化的矩形区

### 坐标映射 ###

*  在场景中操作图形项时，进行场景到图形项、图形项到图形项，或视图到场景之间的坐标变换是比较有用的，即坐标映射
 *  **例如：**
    
     *  **在QGraphicsView的视口上单击鼠标时，通过函数QGraphicsView::maoToScene()可以将视图坐标映射为场景坐标，然后用QGraphicsScene::itemAt()函数可以获取场景中鼠标光标处的图形项**

**12  Graphics View相关函数**

> ### 视图类（QGraphicsView类） ###
> 
>  *  QGraphicsView用于观察一个场景的物理窗口，
>  *  当场景小于视图时，整个场景在视图中可见；当场景大于视图时，视图自动提供卷滚条
>  *  QGraphicsView的视口坐标等于显示设备的物理坐标，但是也可以对QGraphicsView的坐标进行平移、旋转、缩放等变换
>  *  **下面的set函数都有对应的读取函数，**如setScene()有对应的读取函数scene()，下面只列出设置函数(省略了参数)**：**
> 
> ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNDUzMjg1_size_16_color_FFFFFF_t_70][]

> ### 场景类（QGraphicsScene类） ###
> 
>  *  QGraphicsScene适用于管理图形项的场景，是图形项的容器，有添加、删除图形项的函数，管理图形项的各种函数
>  *  **下面是一些主要函数（省略了参数）：**
> 
> ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNDUzMjg1_size_16_color_FFFFFF_t_70 1][]

> ### 图形项 ###
> 
>  *  QGraphicsItem是所有图形项的基类，用户也可以从QGraphicsItem继承定义自己的图形项
>  *  Qt定义了一些常见的图形项，常见的图形项的类的继承关系如下图
> 
> ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNDUzMjg1_size_16_color_FFFFFF_t_70 2][]
> 
>  *  下面是QGraphicsItem类供的图形项操作函数（省略了参数）
> 
> ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNDUzMjg1_size_16_color_FFFFFF_t_70 3][]
> 
>  *  setFlags()函数：可以设置一个图形项的操作标志，包括可选择、可移动、可获取焦点等，例如下图
> 
> ![20190825174834675.png][]
> 
>  *  setPos()函数：设置图形项在父项中的坐标，如果没有父项，就是在场景中的坐标
>  *  setZValue()函数：控制图形项的叠放次序，当有多个图形项有重叠时，zValue越大，越显示在前面
>  *  setRotation()函数：对图形项进行旋转
>  *  setScale()函数：对图形项进行缩放
> 
> 图形项还可以与其他图形项、父项、场景之间进行坐标转换，在后面讲解
