最后界面
1、创建单文档exe,支持切分窗口。

2、新建对话框资源

ID为IDD_TREEVIEW,Style=CHILD,BORDER=NONE,
删掉按钮OK和CANCEL,添加Tree控件IDC_TREE,占满整个对话框
 
导入位图资源,ID为IDB_BITMAP

新建列表对话框IDD_LISTCTRLVIEW,Style=CHILD,BORDER=NONE,
添加LISTCONTROL控件IDC_LIST,占满蓝色边框,
 
和编辑视图的对话框资源IDD_EDITVIEW,Style=CHILD,BORDER=NONE,删掉上面的按钮。
添加EditBox控件IDC_EDIT,占满蓝色边界线
 
3、新建视图类并添加控件型变量和初始化函数
建立2 个View 的类,这里我们让这2个View 的类继承于FormView,
CListControlView 继承于FormView 关联对话框 IDD_LISTVIEW,为了后面可以new 将构造函数改为publlic属性(默认为protected)
-
class CListControlView : public CFormView
-
{
-
public:
-
CListControlView(); // protected constructor used by dynamic creation
-
DECLARE_DYNCREATE(CListControlView)
为列边框添加控件类型变量m_listCtrl

为对话框添加OnSize消息,使列表框与对话框等大
-
void CListControlView::OnSize(UINT nType, int cx, int cy)
-
{
-
CFormView::OnSize(nType, cx, cy);
-
-
// TODO: Add your message handler code here
-
CFormView::ShowScrollBar(SB_VERT,FALSE);
-
CFormView::ShowScrollBar(SB_HORZ,FALSE);
-
if (GetSafeHwnd())
-
{
-
if (m_listCtrl.GetSafeHwnd())
-
{
-
CRect rect(0,0,cx,cy);
-
m_listCtrl.MoveWindow(&rect);
-
}
-
}
-
}
添加虚函数,初始化列表框
-
void CListControlView::OnInitialUpdate()
-
{
-
CFormView::OnInitialUpdate();
-
-
// TODO: Add your specialized code here and/or call the base class
-
CRect rect;
-
m_listCtrl.GetClientRect(&rect);
-
-
m_listCtrl.InsertColumn(0, "From", LVCFMT_LEFT, rect.Width()/4);
-
m_listCtrl.InsertColumn(1, "Subject", LVCFMT_LEFT, rect.Width()/4);
-
m_listCtrl.InsertColumn(2, "Date", LVCFMT_LEFT, rect.Width()/4);
-
m_listCtrl.InsertColumn(3, "Size", LVCFMT_LEFT, rect.Width()/4);
-
}
CEditControlView 继承于FormView 关联对话框IDD_EDITVIEW,为了后面可以new 将构造函数改为publlic属性(默认为protected)
-
class CEditControlView : public CFormView
-
{
-
public:
-
CEditControlView(); // protected constructor used by dynamic creation
为CEditControlView上的编辑控件添加控件型变量m_editCtrl

为对话框添加OnSize消息,使编辑框与对话框等大
-
void CEditControlView::OnSize(UINT nType, int cx, int cy)
-
{
-
CFormView::OnSize(nType, cx, cy);
-
-
// TODO: Add your message handler code here
-
CFormView::ShowScrollBar(SB_VERT,FALSE);
-
CFormView::ShowScrollBar(SB_HORZ,FALSE);
-
//编辑框与窗口大小一样
-
if (GetSafeHwnd())
-
{
-
if (m_editCtrl.GetSafeHwnd())
-
{
-
CRect rect(0,0,cx,cy);
-
m_editCtrl.MoveWindow(&rect);
-
}
-
}
-
}
现在创建关联树控件的视图类
CLeftPaneView : public CFormView关联对话框 IDD_TREEVIEW。
为CLeftPaneView树控件关联一个控件类型的变量m_treeCtrl

为对话框添加OnSize消息,使树控件与对话框等大
-
void CLeftPaneView::OnSize(UINT nType, int cx, int cy)
-
{
-
CFormView::OnSize(nType, cx, cy);
-
-
// TODO: Add your message handler code here
-
if (GetSafeHwnd())
-
{
-
CRect rect;
-
GetClientRect(&rect);
-
if (m_treeCtrl.GetSafeHwnd())
-
m_treeCtrl.MoveWindow(&rect);
-
}
-
}
添加OnInitialUpdate()虚函数,初始化树控件
-
void CLeftPaneView::OnInitialUpdate()
-
{
-
CFormView::OnInitialUpdate();
-
-
// TODO: Add your specialized code here and/or call the base class
-
m_ImageList.Create(IDB_BITMAP, 16, 1, RGB(255, 0, 255));
-
m_treeCtrl.SetImageList(&m_ImageList, LVSIL_NORMAL);
-
-
m_hSplitterView = m_treeCtrl.InsertItem("Splitter View", 0, 0);
-
m_hListCtrlView = m_treeCtrl.InsertItem("ListCtrl View", 1, 1);
-
m_hEditView = m_treeCtrl.InsertItem("EditCtrl View", 2, 2);
-
}
-
4、创建一个切分窗口类
其实质是在切分窗口添加编辑视图和列表视图对象。
源文件中添加
-
#include "ListControlView.h"
-
#include "EditControlView.h"
为了后面可以new CSplitterView将构造函数改为publlic属性(默认为protected)
-
class CSplitterView : public CView
-
{
-
public: // changed from protected
-
CSplitterView(); // protected constructor used by dynamic creation
-
//
-
//
-
};
-
int CSplitterView::OnCreate(LPCREATESTRUCT lpCreateStruct)
-
{
-
if (CView::OnCreate(lpCreateStruct) == -1)
-
return -1;
-
-
// TODO: Add your specialized creation code here
-
m_wndSplitter.CreateStatic(this, 2, 1);
-
-
CCreateContext *pContext = (CCreateContext*) lpCreateStruct->lpCreateParams;
-
-
m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CListControlView), CSize(150,0), pContext);
-
m_wndSplitter.CreateView(1,0,RUNTIME_CLASS(CEditControlView), CSize(0,0), pContext);
-
-
return 0;
-
}
添加成员变量
-
// Attributes
-
public:
-
CSplitterWnd m_wndSplitter;
-
添加WM_CREATE、WM_SIZE消息响应
-
int CSplitterView::OnCreate(LPCREATESTRUCT lpCreateStruct)
-
{
-
if (CView::OnCreate(lpCreateStruct) == -1)
-
return -1;
-
-
// TODO: Add your specialized creation code here
-
m_wndSplitter.CreateStatic(this, 2, 1);
-
-
CCreateContext *pContext = (CCreateContext*) lpCreateStruct->lpCreateParams;
-
-
m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CListCtrlView), CSize(150,0), pContext);
-
m_wndSplitter.CreateView(1,0,RUNTIME_CLASS(CEditCtrlView), CSize(0,0), pContext);
-
-
return 0;
-
}
-
-
void CSplitterView::OnSize(UINT nType, int cx, int cy)
-
{
-
CView::OnSize(nType, cx, cy);
-
-
// TODO: Add your message handler code here
-
m_wndSplitter.MoveWindow(-2,-2,cx+4,cy+4);
-
m_wndSplitter.SetRowInfo(0, cy-(cy/4), 0);
-
m_wndSplitter.SetRowInfo(1, cy/4, 20);
-
m_wndSplitter.RecalcLayout();
-
-
}
-
5、创建右侧切分窗口的框架类
因为所有视图都要放在框架窗口中,所以,右面板需要一个框架窗口。
新建框架窗口类CRightPaneFrame,继承自CFrameWnd。
为了在框架中调用不同视图类,添加成员变量,并定义视图ID
-
#include "SplitterView.h"
-
#include "ListControlView.h"
-
#include "EditControlView.h"
-
-
#define VIEW_SPLITTER 1
-
#define VIEW_LISTCTRL 2
-
#define VIEW_EDIT 3
-
public:
-
CSplitterView* m_pSplitterView;
-
CListControlView* m_pListCtrlView;
-
CEditControlView* m_pEditCtrlView;
-
UINT m_nCurrentViewID;
添加虚函数
-
BOOL CRightPaneFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
-
{
-
// TODO: Add your specialized code here and/or call the base class
-
// TODO: Add your specialized code here and/or call the base class
-
-
m_pSplitterView = new CSplitterView;
-
m_pSplitterView->Create(NULL, NULL, 0L, CFrameWnd::rectDefault, this, VIEW_SPLITTER, pContext);
-
SetActiveView(m_pSplitterView);
-
m_pSplitterView->ShowWindow(SW_SHOW);
-
m_pSplitterView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
-
m_nCurrentViewID = VIEW_SPLITTER;
-
-
m_pListCtrlView = new CListControlView;
-
((CView*) m_pListCtrlView)->Create(NULL, NULL, 0L, CFrameWnd::rectDefault, this, VIEW_LISTCTRL, pContext);
-
m_pListCtrlView->ShowWindow(SW_HIDE);
-
m_pListCtrlView->SetDlgCtrlID(VIEW_LISTCTRL);
-
-
m_pEditCtrlView = new CEditControlView;
-
((CView*) m_pEditCtrlView)->Create(NULL, NULL, 0L, CFrameWnd::rectDefault, this, VIEW_EDIT, pContext);
-
m_pEditCtrlView->ShowWindow(SW_HIDE);
-
m_pEditCtrlView->SetDlgCtrlID(VIEW_EDIT);
-
-
-
RecalcLayout();
-
-
return TRUE;
-
// return CFrameWnd::OnCreateClient(lpcs, pContext);
-
}
添加切换视图的函数
public:
void SwitchToView(UINT nView);
-
void CRightPaneFrame::SwitchToView(UINT nView)
-
{
-
CView* pOldActiveView = GetActiveView();
-
CView* pNewActiveView = NULL;
-
-
switch (nView)
-
{
-
case VIEW_SPLITTER:
-
pNewActiveView = (CView*) m_pSplitterView;
-
break;
-
-
case VIEW_LISTCTRL:
-
pNewActiveView = (CView*) m_pListCtrlView;
-
break;
-
case VIEW_EDIT:
-
pNewActiveView = (CView*) m_pEditCtrlView;
-
break;
-
}
-
-
if (pNewActiveView)
-
{
-
// don't switch when views are the same
-
if (pOldActiveView == pNewActiveView) return;//不变
-
-
SetActiveView(pNewActiveView);//改变活动的视图
-
pNewActiveView->ShowWindow(SW_SHOW);//显示新的视图
-
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
-
pOldActiveView->ShowWindow(SW_HIDE);//隐藏旧的视图
-
pOldActiveView->SetDlgCtrlID(m_nCurrentViewID);
-
m_nCurrentViewID = nView;
-
-
RecalcLayout();//调整框架窗口
-
}
-
}
-
-
注意:
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
实际上AFX_IDW_PANE_FIRST是为了解决多个VIEW的情况下消息转发的问题,这是MFC内部使用的一个固定的值,所有当前的活动视图都会切换到AFX_IDW_PANE_FIRST这个ID,主窗口收到的一些消息(比如命令、通知等等消息)会转发给活动视图来处理,框架通过这个ID来定位活动视图。
当在某个SDI应用程序中使用多个视图并支持视图切换时,很容易忽略这点,造成某些消息得不到正确的响应,
因此当激活某个视图时也要把这个视图的ID改成AFX_IDW_PANE_FIRST。
当主框架调整窗口布局时,即调用RecalcLayout()这个函数时,会将ID为AFX_IDW_PANE_FIRST的窗口/视(必须可见)作为最后一个视图进行拉伸以填充剩余的区域。
6.左面版添加视图类成员变量
在左面版也即树视中添加成员变量,包含右面板和树项
-
// Attributes
-
public:
-
CImageList m_ImageList;
-
HTREEITEM m_hSplitterView;
-
HTREEITEM m_hListCtrlView;
-
HTREEITEM m_hEditView;
-
-
CRightPaneFrame* m_pRightPaneFrame;
头文件class CLeftPaneView : public CFormView前加前置声明,以便使用VIEW_SPLITTER等宏定义
在源文件加
-
#include "RightPaneFrame.h"
添加当树形控件选项改变时消息响应,右边视图变化

-
void CLeftPaneView::OnSelchangedTree(NMHDR* pNMHDR, LRESULT* pResult)
-
{
-
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
-
// TODO: Add your control notification handler code here
-
UINT nView = 0;
-
HTREEITEM hSelectedItem = m_treeCtrl.GetSelectedItem();
-
-
if (hSelectedItem == m_hSplitterView)
-
nView = VIEW_SPLITTER;
-
else
-
if (hSelectedItem == m_hListCtrlView)
-
nView = VIEW_LISTCTRL;
-
else
-
if (hSelectedItem == m_hEditView)
-
nView = VIEW_EDIT;
-
-
if (nView) m_pRightPaneFrame->SwitchToView(nView);
-
-
*pResult = 0;
-
}
7、修改MainFrame,创建静态切分窗口
在源文件中添加
-
#include "LeftPaneView.h"
-
#include "RightPaneFrame.h"
-
修改OnCreateClient函数
-
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
-
{
-
// TODO: Add your specialized code here and/or call the base class
-
if (!m_wndSplitter.CreateStatic(this, 1, 2))
-
{
-
TRACE0("Failed to create splitter window\n");
-
return FALSE;
-
}
-
-
// Get the client rect first for calc left pane size
-
CRect rect;
-
GetClientRect(&rect);
-
-
// create the left tree view first.
-
if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CLeftPaneView), CSize(rect.Width()/3, 0), pContext))
-
{
-
TRACE0("Failed to create left pane view\n");
-
return FALSE;
-
}
-
-
// The right pane is a frame which and contain several different views.
-
// The is can be set to active or non-active
-
if (!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CRightPaneFrame), CSize(0, 0), pContext))
-
{
-
TRACE0("Failed to create right pane frame\n");
-
return FALSE;
-
}
-
-
CLeftPaneView* pLeftPaneView = (CLeftPaneView*) m_wndSplitter.GetPane(0,0);
-
pLeftPaneView->m_pRightPaneFrame = (CRightPaneFrame*) m_wndSplitter.GetPane(0,1);
-
-
// Set the left pane as the active view
-
SetActiveView((CView*) m_wndSplitter.GetPane(0, 0));
-
-
return TRUE;
-
}
-
