不用位图文件的电子钟表
实现步骤：
1 把CGCColorStatic.h/cpp和GCClock.h/cpp加入到工程中
2 在StaticDigitalClock2Dlg.h中添加
#include "GCClock.h"
3 添加如图所示的控件，并为第一个单选按钮IDC_RADIO_12HOURS添加一个变量
int m_iFormat;
4 在StaticDigitalClock2Dlg.h中添加
private:
CGCClock m_Clock;
CGCClock m_StyleExampleA;
CGCClock m_StyleExampleB;
CGCClock m_StyleExampleC;
CGCClock m_StyleExampleD;
5 在构造函数中加入
m_iFormat = 0;
在DoDataExchange(CDataExchange* pDX)的
//{{AFX_DATA_MAP(CStaticDigitalClock2Dlg)上面增加：
DDX_Control(pDX, IDC_STATIC_CLOCK, m_Clock);
DDX_Control(pDX, IDC_STATIC_STYLE_EXA, m_StyleExampleA);
DDX_Control(pDX, IDC_STATIC_STYLE_EXB, m_StyleExampleB);
DDX_Control(pDX, IDC_STATIC_STYLE_EXC, m_StyleExampleC);
DDX_Control(pDX, IDC_STATIC_STYLE_EXD, m_StyleExampleD);
6 在OnInitDialog()中加入：
// TODO: Add extra initialization here
m_StyleExampleA.SetOn(TRUE);
m_StyleExampleA.SetTextOffColor(RGB(0,180,255));
m_StyleExampleA.SetBackgroundOffColor(RGB(0,0,0));
m_StyleExampleA.SetBold();
m_StyleExampleA.SetSunken();
m_StyleExampleA.SetPointFont(12,"Comic Sans MS");
m_StyleExampleA.Start();
m_StyleExampleB.SetOn(FALSE);
m_StyleExampleB.SetTextOffColor(RGB(255,255,255));
m_StyleExampleB.SetPointFont(11,"Times New Roman");
// m_StyleExampleB.SetBold();
m_StyleExampleB.SetColorFrame(TRUE,2,RGB(190,0,0));
m_StyleExampleB.Start();
m_StyleExampleC.SetOn(FALSE);
m_StyleExampleC.SetTextOffColor(RGB(0,0,255));
m_StyleExampleC.SetBackgroundOffColor(RGB(0,0,0));
m_StyleExampleC.SetBold();
m_StyleExampleC.SetSunken();
m_StyleExampleC.SetPointFont(12,"幼圆");
m_StyleExampleC.Start();
m_StyleExampleD.SetOn(FALSE);
m_StyleExampleD.SetTextOffColor(RGB(0,255,0));
m_StyleExampleD.SetBackgroundOffColor(RGB(0,0,0));
m_StyleExampleD.SetBold();
m_StyleExampleD.SetSunken();
m_StyleExampleD.SetPointFont(12,"楷体GB2312");
m_StyleExampleD.Start();
m_Clock.SetOn(FALSE);
m_Clock.SetTextOffColor(RGB(0,180,255));
m_Clock.SetBackgroundOffColor(RGB(0,0,50));
m_Clock.SetBold();
m_Clock.SetPointFont(9,"Arial");
m_Clock.SetModalFrame();
m_Clock.Start();
7 写单选按钮响应函数
void CStaticDigitalClock2Dlg::OnRadio12hours()
...{
m_Clock.Format();
}
void CStaticDigitalClock2Dlg::OnRadio24hours()
...{
m_Clock.Format(TRUE);
}
