在MFC9(在vc2008和vc2010中,已经有了CTabView的现成类)以前的版本中,有CListView,CTreeView,CEditView,CRichEditView等控件视图类,但就是没有类似的CTabView类,因工作需要,最近在做一个简单的多标签IE浏览器,开发环境是vs2005,基本框架是sdi + chtmlview + ctabview,因此自行封装实现了CTabView,并把它作为一个重要的基础类来维护使用。先来说下我这个CTabView类的特点及功能:
1)CTabView本质上就是一种窗口容器,基于CCtrlView实现,能够容纳类型为CWnd的所有窗口,并作为它的子窗口(为描述方便,在这特称为视图页面),每个标签对应一个视图页面。
2)扩展了标准的标签项数据结构TC_ITEM,即自定义了一个TC_EXTRA_ITEM扩展数据结构,该结构除包含标准的数据结构(第1个成员)外,还包括视图页面对象、内部标志、视图页面标题、视图页面关联数据4种类型数据,扩展数据大小需要在创建后插入标签前调用SetItemExtra设定。
3)支持容纳外部窗口和创建内部窗口,前者是指容纳外面已经创建好的窗口;后者是根据窗口类型信息,由CTabView自己来管理创建视图页面。
4)对于内部窗口的管理,为方便区分并有利于消息映射处理,因此窗口ID是唯一的,即在创建时分派一个新的不同的ID,销毁时回收到ID数组中。而外部窗口ID则由外部管理。
5)提供激活视图页面后的自定义处理,表现为OnViewActivated虚函数。
6)提供右键单击Tab标签后的自定义处理,表现为OnTabContextMenu虚函数。
7)提供Tab标签提示信息的自定义处理,表现为UpdateTooltipText虚函数。
8)提供CTabView视图类的自绘处理(须设定TCS_OWNERDRAWFIXED样式),表现为DrawItem虚函数。
9)Tab标签的文本默认是简写的,即当长度超过最大值时,多余部分用省略号...代替,同时也支持自定义处理,表现为ShortenTitle虚函数。
10)对上述特点7,为了能支持派生类自定义处理,由于提示文本消息的发送者是CToolTipCtrl窗口,而不是CTabView本身,所以不能像TCN_SELCHANGE,NM_RCLICK等通知消息可以使用反射宏来实现,因此使用了窗口子类化来捕获父窗口的TTN_GETDISPINFO通知消息实现的。这一行为也可以通过UpdateTooltipText来定制,当其返回值是TRUE时,表示允许消息默认被父窗口接收处理,否则,反之。
11)对上述特点8,本可以重载OnChildNotify来实现WM_DRAWITEM消息的回调,但为了简洁,如同TTN_GETDISPINFO通知消息,也是使用窗口子类化来捕获实现的。
12)对上述10和11的消息捕获处理,使用了CBasicSubClassWnd类来实现,表现为重写其SubWindowProc虚函数。

#endif 从上可知,CTabView主要包括2大类操作方法,一是针对视图页面窗口,二是针对Tab标签扩展数据。说明如下
1)增加视图页面:AddIView,有2个重载形式,其中带CRuntimeClass和CCreateConext类型参数的用于创建内部窗口,成功返回对应的窗口,否则为NULL;带CWnd参数的用于容纳外部窗口,成功返回TRUE,否则返回FALSE。
2)插入视图页面:InsertView,有2个重载形式,其中带CRuntimeClass和CCreateConext类型参数的用于创建内部窗口,成功返回对应的窗口,否则为NULL;带CWnd参数的用于容纳外部窗口,成功返回TRUE,否则返回FALSE。
3)移除某个视图页面:RemoveView,有2个重载形式,其中int类型参数的用于按索引移除,CWnd类型的用于按窗口对象移除。
4)移除所有视图页面:RemoveAllView。5)获取活动视图页面:有2个方法,GetActiveView如果无活动视图页面,则返回NULL,否则返回对应的窗口;GetActiveViewIndex如果无活动视图页面,则返回-1,否则返回>=0的索引值。
5)设置活动视图页面:有2个方法:SetActiveView按窗口来设置,SetActiveViewIndex按索引来设置。
6)视图页面窗口与索引的相互转换:GetView由窗口得到其索引,操作失败返回-1,否则返回>=0的索引值。GetIndex由索引得到窗口,失败返回NULL,否则返回对应的窗口。
7)获取视图页面的数量:GetViewCount。
8)设置视图页面的标题:SetViewTitle,有2个重载形式,int类型参数的按索引设置,CWnd类型参数的按窗口设置,成功返回TRUE,否则返回FALSE。
9)获取视图页面的标题:GetViewTitle,有2个重载形式,int类型参数的按索引获取,CWnd类型参数的按窗口获取,成功返回TRUE,否则返回FALSE。
10)设置图像列表:SetImageList。
11)获取图像列表:GetImageList。
12)设置视图页面的图像:有2个重载形式,int类型参数的按索引设置,CWnd类型参数的按窗口设置,成功返回TRUE,否则返回FALSE。
13)获取视图页面的图像:有2个重载形式,int类型参数的按索引获取,CWnd类型参数的按窗口获取,成功返回TRUE,否则返回FALSE。
14)设置视图页面的数据:有2个重载形式,int类型参数的按索引设置,CWnd类型参数的按窗口设置,成功返回TRUE,否则返回FALSE。
15)获取视图页面的数据:有2个重载形式,int类型参数的按索引获取,CWnd类型参数的按窗口获取,成功返回TRUE,否则返回FALSE。
16)视图页面内部标志查询:有2个重载形式,int类型参数的按索引查询,CWnd类型参数的按窗口查询,成功返回TRUE,否则返回FALSE,当操作成功时,参数bInner为TRUE表示为CTabView内部创建的窗口,否则表示外部窗口。
