最后界面
1、創(chuàng)建單文檔exe,支持切分窗口。
2、新建對話框資源
ID為IDD_TREEVIEW,Style=CHILD,BORDER=NONE,
刪掉按鈕OK和CANCEL,添加Tree控件IDC_TREE,占滿整個對話框
導(dǎo)入位圖資源,ID為IDB_BITMAP
新建列表對話框IDD_LISTCTRLVIEW,Style=CHILD,BORDER=NONE,
添加LISTCONTROL控件IDC_LIST,占滿藍色邊框,
和編輯視圖的對話框資源IDD_EDITVIEW,Style=CHILD,BORDER=NONE,刪掉上面的按鈕。
添加EditBox控件IDC_EDIT,占滿藍色邊界線
3、新建視圖類并添加控件型變量和初始化函數(shù)
建立2 個View 的類,這里我們讓這2個View 的類繼承于FormView,
CListControlView 繼承于FormView 關(guān)聯(lián)對話框 IDD_LISTVIEW,為了后面可以new 將構(gòu)造函數(shù)改為publlic屬性(默認為protected)
[cpp]
view plaincopyclass CListControlView : public CFormView
{
public:
CListControlView(); // protected constructor used by dynamic creation
DECLARE_DYNCREATE(CListControlView)
[cpp]
view plaincopy};
為列邊框添加控件類型變量m_listCtrl
為對話框添加OnSize消息,使列表框與對話框等大
[html]
view plaincopyvoid 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);
}
}
}
添加虛函數(shù),初始化列表框
[cpp]
view plaincopyvoid 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 繼承于FormView 關(guān)聯(lián)對話框IDD_EDITVIEW,為了后面可以new 將構(gòu)造函數(shù)改為publlic屬性(默認為protected)
[cpp]
view plaincopyclass CEditControlView : public CFormView
{
public:
CEditControlView(); // protected constructor used by dynamic creation
為CEditControlView上的編輯控件添加控件型變量m_editCtrl
為對話框添加OnSize消息,使編輯框與對話框等大
[cpp]
view plaincopyvoid 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);
//編輯框與窗口大小一樣
if (GetSafeHwnd())
{
if (m_editCtrl.GetSafeHwnd())
{
CRect rect(0,0,cx,cy);
m_editCtrl.MoveWindow(&rect);
}
}
}
現(xiàn)在創(chuàng)建關(guān)聯(lián)樹控件的視圖類
CLeftPaneView : public CFormView關(guān)聯(lián)對話框 IDD_TREEVIEW。
為CLeftPaneView樹控件關(guān)聯(lián)一個控件類型的變量m_treeCtrl
為對話框添加OnSize消息,使樹控件與對話框等大
[cpp]
view plaincopyvoid 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()虛函數(shù),初始化樹控件
[cpp]
view plaincopyvoid 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、創(chuàng)建一個切分窗口類
其實質(zhì)是在切分窗口添加編輯視圖和列表視圖對象。
源文件中添加
[cpp]
view plaincopy#include "ListControlView.h"
#include "EditControlView.h"
為了后面可以new CSplitterView將構(gòu)造函數(shù)改為publlic屬性(默認為protected)
[html]
view plaincopyclass CSplitterView : public CView
{
public: // changed from protected
CSplitterView(); // protected constructor used by dynamic creation
//
//
};
[cpp]
view plaincopyint 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;
}
添加成員變量
[cpp]
view plaincopy// Attributes
public:
CSplitterWnd m_wndSplitter;
添加WM_CREATE、WM_SIZE消息響應(yīng)
[cpp]
view plaincopyint 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、創(chuàng)建右側(cè)切分窗口的框架類
因為所有視圖都要放在框架窗口中,所以,右面板需要一個框架窗口。
新建框架窗口類CRightPaneFrame,繼承自CFrameWnd。
為了在框架中調(diào)用不同視圖類,添加成員變量,并定義視圖ID
[cpp]
view plaincopy#include "SplitterView.h"
#include "ListControlView.h"
#include "EditControlView.h"
#define VIEW_SPLITTER 1
#define VIEW_LISTCTRL 2
#define VIEW_EDIT 3
[cpp]
view plaincopypublic:
CSplitterView* m_pSplitterView;
CListControlView* m_pListCtrlView;
CEditControlView* m_pEditCtrlView;
UINT m_nCurrentViewID;
添加虛函數(shù)
[cpp]
view plaincopyBOOL 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);
}
添加切換視圖的函數(shù)
public:
void SwitchToView(UINT nView);
[cpp]
view plaincopyvoid 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;//不變
SetActiveView(pNewActiveView);//改變活動的視圖
pNewActiveView->ShowWindow(SW_SHOW);//顯示新的視圖
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
pOldActiveView->ShowWindow(SW_HIDE);//隱藏舊的視圖
pOldActiveView->SetDlgCtrlID(m_nCurrentViewID);
m_nCurrentViewID = nView;
RecalcLayout();//調(diào)整框架窗口
}
}
注意:
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
實際上AFX_IDW_PANE_FIRST是為了解決多個VIEW的情況下消息轉(zhuǎn)發(fā)的問題,這是MFC內(nèi)部使用的一個固定的值,所有當前的活動視圖都會切換到AFX_IDW_PANE_FIRST這個ID,主窗口收到的一些消息(比如命令、通知等等消息)會轉(zhuǎn)發(fā)給活動視圖來處理,框架通過這個ID來定位活動視圖。
當在某個SDI應(yīng)用程序中使用多個視圖并支持視圖切換時,很容易忽略這點,造成某些消息得不到正確的響應(yīng),
因此當激活某個視圖時也要把這個視圖的ID改成AFX_IDW_PANE_FIRST。
當主框架調(diào)整窗口布局時,即調(diào)用RecalcLayout()這個函數(shù)時,會將ID為AFX_IDW_PANE_FIRST的窗口/視(必須可見)作為最后一個視圖進行拉伸以填充剩余的區(qū)域。
6.左面版添加視圖類成員變量
在左面版也即樹視中添加成員變量,包含右面板和樹項
[cpp]
view plaincopy// Attributes
public:
CImageList m_ImageList;
HTREEITEM m_hSplitterView;
HTREEITEM m_hListCtrlView;
HTREEITEM m_hEditView;
CRightPaneFrame* m_pRightPaneFrame;
頭文件class CLeftPaneView : public CFormView前加前置聲明,以便使用VIEW_SPLITTER等宏定義
[cpp]
view plaincopyclass CRightPaneFrame;
在源文件加
[html]
view plaincopy#include "RightPaneFrame.h"
添加當樹形控件選項改變時消息響應(yīng),右邊視圖變化
[cpp]
view plaincopyvoid 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,創(chuàng)建靜態(tài)切分窗口
在源文件中添加
[cpp]
view plaincopy#include "LeftPaneView.h"
#include "RightPaneFrame.h"
修改OnCreateClient函數(shù)
[cpp]
view plaincopyBOOL 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;
}
