MFC基礎知識(七)——停靠視窗添加工具條

先建立工具條，設ID為IDR_Object，修改程式如下：

ObjectWnd.h修改：

#pragma once
#include "stdafx.h"
#include "afxdockablepane.h"
#include "ObjectDlg.h"
#include "afxwin.h"

//添加繼承類
class CObjectToolBar : public CMFCToolBar
{
public:
    virtual void OnUpdateCmdUI(CFrameWnd* /*pTarget*/, BOOL bDisableIfNoHndler)
    {
        CMFCToolBar::OnUpdateCmdUI((CFrameWnd*) GetOwner(), bDisableIfNoHndler);
    }

    virtual BOOL AllowShowOnList() const { return FALSE; }
};


class CObjectWnd :
    public CDockablePane
{
public:
    CObjectWnd(void);
    ~CObjectWnd(void);
    DECLARE_MESSAGE_MAP()
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    afx_msg void OnSize(UINT nType, int cx, int cy);
    afx_msg void OnDestroy();


    CObjectToolBar m_wndToolBar;//工具條對象
    CObjectDlg m_objectDlg; //對話框類

    void AdjustLayout();

};
           

ObjectWnd.cpp修改：

#include "stdafx.h"
#include "ObjectWnd.h"
#include "resource.h"
#include "MainFrm.h"
#include "CSDNtest.h"//添加此頭檔案（工程名.h）

CObjectWnd::CObjectWnd(void)
{
}


CObjectWnd::~CObjectWnd(void)
{
}

BEGIN_MESSAGE_MAP(CObjectWnd, CDockablePane)
    ON_WM_CREATE()
    ON_WM_SIZE()
    ON_WM_DESTROY()
END_MESSAGE_MAP()


void CObjectWnd::AdjustLayout()
{
    if (GetSafeHwnd () == NULL || (AfxGetMainWnd() != NULL && AfxGetMainWnd()->IsIconic()))
    {
        return;
    }
    CRect rectClient;
    GetClientRect(rectClient);

    //設定工具條位置
    int cyTlb = m_wndToolBar.CalcFixedLayout(FALSE, TRUE).cy;
    m_wndToolBar.SetWindowPos(NULL, rectClient.left, rectClient.top, rectClient.Width(),cyTlb, SWP_NOACTIVATE | SWP_NOZORDER);

    //控件在視窗中所占空間大小
    m_objectDlg.SetWindowPos(this,rectClient.left,rectClient.top+cyTlb,rectClient.Width(),rectClient.Height()-cyTlb,SWP_NOACTIVATE | SWP_NOZORDER);

}

int CObjectWnd::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CDockablePane::OnCreate(lpCreateStruct) == -)
        return -1;

    CRect rectDummy;
    rectDummy.SetRectEmpty();

    // 建立組合:
    const DWORD dwViewStyle = WS_CHILD | WS_VISIBLE | CBS_DROPDOWNLIST | WS_BORDER | CBS_SORT | WS_CLIPSIBLINGS | WS_CLIPCHILDREN;


    //建立工具條
    m_wndToolBar.Create(this, AFX_DEFAULT_TOOLBAR_STYLE, IDR_Object);
    m_wndToolBar.LoadToolBar(IDR_Object, , , TRUE /* 已鎖定*/);
    m_wndToolBar.CleanUpLockedImages();
    m_wndToolBar.LoadBitmap(theApp.m_bHiColorIcons ? IDR_Object : IDR_Object, , , TRUE /* 鎖定*/);

    m_wndToolBar.SetPaneStyle(m_wndToolBar.GetPaneStyle() | CBRS_TOOLTIPS | CBRS_FLYBY);
    m_wndToolBar.SetPaneStyle(m_wndToolBar.GetPaneStyle() & ~(CBRS_GRIPPER | CBRS_SIZE_DYNAMIC | CBRS_BORDER_TOP | CBRS_BORDER_BOTTOM | CBRS_BORDER_LEFT | CBRS_BORDER_RIGHT));
    m_wndToolBar.SetOwner(this);

    // 所有指令将通過此控件路由，而不是通過主架構路由:
    m_wndToolBar.SetRouteCommandsViaFrame(FALSE);




    // 建立對話框視窗:
    if (!m_objectDlg.Create(IDD_ObjectDlg,this))
    {
        TRACE0("未能建立對話框視窗\n");
        return -1;      // 未能建立
    }
    m_objectDlg.ShowWindow(SW_SHOW);
    AdjustLayout();


    return 0;
}


void CObjectWnd::OnSize(UINT nType, int cx, int cy)
{
    CDockablePane::OnSize(nType, cx, cy);

    AdjustLayout();
}

void CObjectWnd::OnDestroy()
{
    CDockablePane::OnDestroy();
    m_objectDlg.DestroyWindow();
    // TODO: 在此處添加消息處理程式代碼
}

           

運作結果：
