_**1.MFC如何设置背景颜色

**_

首先，为对话框添加WM_CTLCOLOR消息，方法为：右击Dialog窗口 --> Class Wizard --> Messages --> WM_CTLCOLOR --> Add Handler --> Edit Code

然后，在Dlg.h文件中添加成员变量CBrush m_brush;

接着，在之前Edit Code的位置，写上

HBRUSH CMFCInterfaceDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
return m_brush;
}

最后，在Dlg.cpp文件的OnInitDialog()函数后面加上m_brush.CreateSolidBrush(RGB(255, 255, 102));//设置背景颜色为黄色。编译运行函数即可。

2.MFC如何设置背景图片

首先在网上下载一张Bitmap的图片，放在res文件夹下

接着在OnInitDialog()后面加上如下代码

　　　CString strBmpPath = _T(".\\res\\backgroundone.jpg");

CImage img;

img.Load(strBmpPath);

MoveWindow(0, 0, img.GetWidth(), img.GetHeight());

CBitmap bmpTmp;

bmpTmp.Attach(img.Detach());

m\_brush.CreatePatternBrush(&bmpTmp);

3.MFC修改可执行文件和标题栏图标：

创建一个新工程，可以什么都不加。打开.rc，  创建或打开Icon资源（以下都以Icon为例）。    
单击工程窗口的资源视图标签，选中资源ID为IDR_MAINFRAME图标资源，然后按Delete键把它删除掉，当然也可以不删，具体后面会讲到。    
从资源菜单中选择Resource，然后选择Icon，添加资源，选中Icon类型，点击导入，此时会叫你选择本地的图片，记住必须选择.ioc格式的图片，否则导入失败。    
把新图标的资源ID改为IDI_ICON（也可以不改）。 具体做法如下：

有一点很重要，你改知道就是 打开Header Files下的Resource.h，找到Icon下的图标，系统默认是从128开始的，

#define IDR_MAINFRAME               128

#define IDR_ICONTETYPE             129(单/多文档程序的文档图标)

#define IDI_ICON1                            130

#define IDI_ICON2                            131

a.修改exe文件图标

VS2010生成的exe文件图标是用Icon下几个图标中value值最小的，顺序为IDR_MAINFRAME、IDR_ICONTETYPE、新加 的，所以想更改生成的exe文件图标，只要保证图标的value值是Icon下几个图标中最小的就可以了

　　1. 导入自己的.ioc图片，并在Resource.h中，将自己加的icon资源Value改为最小，如下，因此不一定要删除IDR_MAINFRAME

#define IDR_MAINFRAME                   129

#define IDI_ICON1                               128（自己添加的icon）

　　2. 然后编译运行，找到你的debug目录，你将看到图标已经更改的.exe执行文件，这种方法可以将任何你喜欢的图片做成.exe文件图标

b.修改标题栏图标

　　1. 如上操作，导入自己喜爱的ico图片，编辑新加icon的ID，比如我新加的Icon资源ID为 IDI_ICON1

　　22. 基于对话框的程序，在构造函数中有一句

　　 m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

　　  此时把IDR_MAINFRAME改为我的IDI_ICON1的图标名。

4. Button的绘制

首先，拖动几个Button到窗口，然后修改Button的Owner Draw属性为true

接着，右击Dialog窗口 --> Class Wizard --> Messages --> WM_DRAWITEM --> Add Handler --> Edit Code

void CMFCInterfaceDlg::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct)
{
// TODO: Add your message handler code here and/or call default

//获得button标题  
//CString btnCaption = \_T("Dialog");  
CDC\* pDC = CDC::FromHandle(lpDrawItemStruct->hDC);

CString btnCaption = L"";  
//设置标题  
switch (lpDrawItemStruct->CtlID)  
{  
case ID1:  
    btnCaption = "1";  
    break;  
case ID2:  
    btnCaption = "2";  
    break;  
case ID3:  
    btnCaption = "3";  
    break;  
default:  
    ;  
}

CRect drawRect;  
//获得绘图DC  
//得到原Button的矩形大小  
drawRect.CopyRect(&(lpDrawItemStruct->rcItem));  
//绘制控件框架  
pDC->DrawFrameControl(&drawRect, DFC\_BUTTON, lpDrawItemStruct->CtlType);

//创建画刷  
CBrush pBrush;  
pBrush.CreateSolidBrush(RGB(100, 130, 10));  
//画矩形  
pDC->FillRect(drawRect, &pBrush);

//定义一个CRect用于绘制文本  
CRect textRect;  
//拷贝矩形区域  
textRect.CopyRect(&drawRect);  
//获得字符串尺寸  
CSize sz = pDC->GetTextExtent(btnCaption);  
//调整文本位置 居中  
textRect.top += (textRect.Height() - sz.cy) / 2;  
//设置文本背景透明  
pDC->SetBkMode(TRANSPARENT);  
//设置文本颜色  
pDC->SetTextColor(RGB(0, 0, 255));  
//绘制文本内容  
pDC->DrawText(btnCaption, &textRect, DT\_RIGHT | DT\_CENTER | DT\_BOTTOM);

CDialogEx::OnDrawItem(nIDCtl, lpDrawItemStruct);

}

当然，对于不想要改变的Button，将Owner Draw属性设为false就行。

5.static text字体及颜色的绘制

颜色绘制：

在OnCTLColor中

HBRUSH CMFCInterfaceDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
//HBRUSH hbr = CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);

HBRUSH hbr = CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);

if (pWnd == this)  
{  
    return m\_brush;  
}

if (pWnd->GetDlgCtrlID() == (IDC\_STATIC\_TITLE))//IDC\_STATIC\_TITLE:标题ID  
{  
    pDC->SetBkMode(TRANSPARENT);  
    pDC->SetTextColor(RGB(255, 251, 240));  
    return HBRUSH(GetStockObject(HOLLOW\_BRUSH));  
}

if (pWnd->GetDlgCtrlID() == (IDC\_STATIC))//IDC\_STATIC:文本ID  
{  
    pDC->SetBkMode(TRANSPARENT);  
    pDC->SetTextColor(RGB(0, 225, 225));  
    return HBRUSH(GetStockObject(HOLLOW\_BRUSH));  
}

return hbr;

//return m\_brush;

}

额外提示：pDC->SetBkMode(TRANSPARENT);是设置文本背景透明。

字体绘制：

首先，在Dlg.h文件中声明Font变量CFont newFont;

然后，在OnInitDialog()函数后面加上以下代码

    CFont\* font;  
font = static\_title.GetFont();//获取CFont对象  
LOGFONT lf;  
font->GetLogFont(&lf);//获取LOGFONT结构体  
lf.lfHeight = -15;    //修改字体大小  
lf.lfItalic = TRUE;        //倾斜  
lf.lfWeight = 400;   //修改字体的粗细  
newFont.CreateFontIndirectW(&lf);//创建一个新的字体  
static\_title.SetFont(&newFont);

6.MFC取消标题栏，以及自制标题栏

首先，去掉原本的标题栏，将属性Border设置为NONE。

然后，观察上面那张图片，上面那个矩形区域就可以当做标题栏。首先要做的就是为它添加一个退出按钮，就是那个叉叉。

1. 拖动一个button到矩形区域，自行调整大小以及位置，设置它的Caption为大写的X，哈哈哈，其实可以为Button贴图，不过本人为了方便，写个X冒充。将其ID设置为IDC_BUTTON_CLOSE。

2. 为这个Button添加函数，实现单击时关闭程序。双击Button进入代码编辑页面，输入以下代码

void CMFCInterfaceDlg::OnBnClickedButtonClose()
{
CDialog::OnOK();
}

此时，它的退出功能已经完成。但是运行时，可能发现Button的位置偏左，这时候，就可以用代码微调Button的位置，在OnInitDialog()函数后面加上以下代码

CRect rect;
GetDlgItem(IDC_BUTTON_CLOSE)->GetWindowRect(&rect);//获得空间的绝对坐标
ScreenToClient(&rect);//获得相对于主窗体的坐标
rect.OffsetRect(CSize(15, 0));//这里要是要移动的相对位置
GetDlgItem(IDC_BUTTON_CLOSE)->MoveWindow(rect);//移动到目标位置

数字可以自己调节。

另外关于Button贴图的，附上此链接：https://blog.csdn.net/u011711997/article/details/52551106

7. 如何实现标题栏的拖动功能

需要添加三个函数

void CTestDllDlg::OnLButtonUp(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
ReleaseCapture();

CDialogEx::OnLButtonUp(nFlags, point);

}

void CTestDllDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
SetCapture();

CDialogEx::OnLButtonDown(nFlags, point);

}

void CTestDllDlg::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default

static CPoint PrePoint = CPoint(0, 0);  
if (MK\_LBUTTON == nFlags)  
{  
    if (point != PrePoint)  
    {  
        CPoint ptTemp = point - PrePoint;  
        CRect rcWindow;  
        GetWindowRect(&rcWindow);  
        rcWindow.OffsetRect(ptTemp.x, ptTemp.y);  
        MoveWindow(&rcWindow);  
        return;  
    }  
}  
PrePoint = point;

CDialogEx::OnMouseMove(nFlags, point);

}

亲测可用，捕捉鼠标按下与释放。
