1、图形编程（三）,1、微调按钮,设置属性: Auto Buddy(自动取关联控件为TAB顺序前一个) Set Buddy Interger(使控件设置关联控件数值，这个值可以是十进制或十六进制) Wrap(数值超过范围时循环) Arrow keys(当按下向上和向下方向键时，控件可以增加或减小) No thousands(不在每三位时加逗号),/ TODO: Add extra initialization here /设置红色值微调按钮 CSpinButtonCtrl *pSpinRed = (CSpinButtonCtrl*)GetDlgItem(IDC_SPIN_RED); ASSERT(
2、pSpinRed!=NULL); /设置伙伴窗口 pSpinRed-SetBuddy(GetDlgItem(IDC_EDT_RED); pSpinRed-SetRange(0,255); pSpinRed-SetPos(128); /设置绿色值微调按钮 CSpinButtonCtrl *pSpinGreen = (CSpinButtonCtrl*)GetDlgItem(IDC_SPIN_GREEN); ASSERT(pSpinGreen!=NULL); /设置伙伴窗口 pSpinGreen-SetBuddy(GetDlgItem(IDC_EDT_GREEN); pSpinGreen-SetRa
3、nge(0,255); pSpinGreen-SetPos(128); /设置蓝色值微调按钮 CSpinButtonCtrl *pSpinBlue = (CSpinButtonCtrl*)GetDlgItem(IDC_SPIN_BLUE); ASSERT(pSpinBlue!=NULL); /设置伙伴窗口 pSpinBlue-SetBuddy(GetDlgItem(IDC_EDT_BLUE); pSpinBlue-SetRange(0,255); pSpinBlue-SetPos(128);,2、滑动条,/设置红色值滑动条 CSliderCtrl *pSliderRed = (CSliderC

5、设置蓝色值滑动条 CSliderCtrl *pSliderBlue = (CSliderCtrl*)GetDlgItem(IDC_SLIDER_BLUE); ASSERT(pSliderBlue!=NULL); /设置滑动条取值范围 pSliderBlue-SetRange(0,255); pSliderBlue-SetPos(128);,int iRed,iGreen,iBlue; /得到红色、绿色和蓝色滑动条滚动事件 if (pScrollBar-GetDlgCtrlID() = IDC_SLIDER_RED) | (pScrollBar-GetDlgCtrlID() = IDC_SLID
