1.10 开发技巧与难点分析（2）
（7）在自定义函数DrawDialog中添加代码，用于绘制对话框的右边标题。代码如下：
if(Flags & FRIGHTTITLE) //绘制右标题
{
DeleteObject(LeftLine);
LeftLine.LoadBitmap(IDB_RIGHTTITLE); //加载右标题位图资源
//获取位图大小
LeftLine.GetObject(sizeof(bitinfo),&bitinfo);
OldObj = memDC.SelectObject(&LeftLine);
x = bitinfo.bmiHeader.biWidth; //获取位图宽
y = bitinfo.bmiHeader.biHeight; //获取位图高
m_TitleDrawHeight = (m_CaptionHeight+4 > y) m_
CaptionHeight+4 : y; //计算右标题高度
m_RTitleRc.CopyRect(CRect(FactRC.right-x,0,FactRC.right,
m_TitleDrawHeight)); //右标题区域
WindowDC.StretchBlt(m_RTitleRc.left,m_RTitleRc.top,m_RTitleRc.Width(),
m_RTitleRc.Height(),&memDC,0,0,x,y,SRCCOPY); //绘制右标题
DeleteObject( memDC.SelectObject(OldObj));
LeftLine.Detach();
} | （8）在自定义函数DrawDialog中添加代码，用于绘制对话框的中间标题。代码如下：
if(Flags & FMIDTITLE) //绘制中间标题
{
DeleteObject(LeftLine);
LeftLine.LoadBitmap(IDB_MIDTITLE); //加载中间标题位图资源
//获取位图大小
LeftLine.GetObject(sizeof(bitinfo),&bitinfo);
OldObj = memDC.SelectObject(&LeftLine);
x = bitinfo.bmiHeader.biWidth; //获取位图宽
y = bitinfo.bmiHeader.biHeight; //获取位图高
m_TitleDrawHeight = (m_CaptionHeight+4 > y) m_
CaptionHeight+4 : y ; //计算中间标题高度
m_MTitleRc.CopyRect(CRect(m_LTitleRc.right,0,m_
RTitleRc.left,m_TitleDrawHeight));
WindowDC.StretchBlt(m_MTitleRc.left,m_MTitleRc.
top,m_MTitleRc.Width(),
m_MTitleRc.Height(),&memDC,0,0,x,y,SRCCOPY); //绘制中间标题
LeftLine.Detach();
memDC.SelectObject(OldObj);
}
| （9）在自定义函数DrawDialog中添加代码，用于绘制对话框的右边框。代码如下：
if(Flags & FRIGHTBAR) //绘制右边框
{
DeleteObject(LeftLine);
LeftLine.LoadBitmap(IDB_RIGHTBAR); //加载右边框位图资源
//获取位图大小
LeftLine.GetObject(sizeof(bitinfo),&bitinfo);
OldObj = memDC.SelectObject(&LeftLine);
x = bitinfo.bmiHeader.biWidth; //获取位图宽
y = bitinfo.bmiHeader.biHeight; //获取位图高
rLineWidth = m_FrameWidth + m_BorderWidth;
rLineWidth = rLineWidth>x rLineWidth:x;
WindowDC.StretchBlt(m_RTitleRc.right-rLineWidth,m_
TitleDrawHeight,rLineWidth,
FactRC.Height()-m_TitleDrawHeight,&memDC,0,0,x,y,
SRCCOPY) //绘制右边框
memDC.SelectObject(OldObj);
LeftLine.Detach();
}
| （10）自定义函数DrawDialog添加代码，用于绘制对话框的底边框。代码如下：
if(Flags & FBOTTOMBAR) //绘制底边框
{
DeleteObject(LeftLine);
LeftLine.LoadBitmap(IDB_BOTTOMBAR); //加载底边框位图资源
//获取位图大小
LeftLine.GetObject(sizeof(bitinfo),&bitinfo);
OldObj = memDC.SelectObject(&LeftLine);
x = bitinfo.bmiHeader.biWidth; //获取位图宽
y = bitinfo.bmiHeader.biHeight; //获取位图高
bLineHeight = m_BorderHeight + m_FrameHeight;
bLineHeight = bLineHeight>y bLineHeight:y;
WindowDC.StretchBlt(leftlinewidth,FactRC.Height
()-bLineHeight,m_RTitleRc.right
-rLineWidth-leftlinewidth, bLineHeight,&memDC,
0,0,x,y,SRCCOPY); //绘制底边框
memDC.SelectObject(OldObj);
LeftLine.Detach();
}
| （11）在自定义函数DrawDialog中添加代码，用于绘制对话框的最小化按钮。代码如下：
if(Flags & FMINBUTTON) //绘制最小化按钮
{
DeleteObject(LeftLine);
LeftLine.LoadBitmap(IDB_MINBT); //加载最小化按钮
//获取位图大小
LeftLine.GetObject(sizeof(bitinfo),&bitinfo);
OldObj = memDC.SelectObject(&LeftLine);
x = bitinfo.bmiHeader.biWidth; //获取位图宽
y = bitinfo.bmiHeader.biHeight; //获取位图高
WindowDC.StretchBlt(m_MinRect.left,m_MinRect.top,m_MinRect.right,
m_MinRect.bottom,&memDC,0,0,x,y,SRCCOPY); //绘制最小化按钮
memDC.SelectObject(OldObj);
LeftLine.Detach();
}
| （12）在自定义函数DrawDialog中添加代码，用于绘制对话框的最大化按钮。代码如下：
if ( Flags & FMAXBUTTON) //绘制最大化按钮
{
DeleteObject(LeftLine);
LeftLine.LoadBitmap(IDB_MAXBT);
//获取位图大小
LeftLine.GetObject(sizeof(bitinfo),&bitinfo);
OldObj = memDC.SelectObject(&LeftLine);
x = bitinfo.bmiHeader.biWidth; //获取位图宽
y = bitinfo.bmiHeader.biHeight; //获取位图高
WindowDC.StretchBlt(m_MaxRect.left,m_MaxRect.top,m_MaxRect.right,
m_MaxRect.bottom,&memDC,0,0,x,y,SRCCOPY); //绘制最大化按钮
memDC.SelectObject(OldObj);
LeftLine.Detach();
