怎样把button变成椭圆形的？

[qjhero]

在Initial....中加上 button->GetDlgItem(ID);
button->SetWindowRgn(...,TRUE);
为什么不行呢？正确该怎样做呢？

或许使用位图作按钮可以吧/
尝试一下有自制控件，也是可以有。我作过。。。
具体实现办法请自个去想吧。

SetWindowRgn

[freejacky]

CButton* button;
CEllipse r;

button=new CButton();
button->Creat(…………)

CButton* button;
CEllipse r;

button=new CButton();
button->Creat(…………)

在RESORCE中的dlg中建一按扭IDC_MYBUTTON,属性设为Variable(自绘)，
在ClassWizard中添加一变量m_Button(ID 为IDC_MYBUTTON，属性为Control)
自建一个CLASS(myButton)基于Cbutton，在dlg定义中把CButton m_Button改为
myButton m_Button.
在myButton 的定义中加上CRgn m_Rgn;
用ClassWizard给myButton消息映射WM_CREATE(OnCreate)．WM_PAINT(OnPaint)，
WM_LBUTTONDOWN(OnLButtonDown),WM_LBUTTONUP(OnLButtonUp),
在OnCreate中加上
CRect rc;
CRgn rgn;
this->GetwindowRect(rc);
rgn.CreateEllipseIndirect(rc);
m_Rgn.CreateRect(rc);
m_Rgn.CopyRgn(&rgn);
this->SetWindowRgn(m_Rgn);
给myButton加上一个绘制函数Draw(bool IsPush)
void myButton::Draw(bool IsPush)
{
CDC *pDC=GetDC(this);
CRgn rgn;
CRect rc;
this->GetWindowRgn(rgn);
this->GetwindowRect(rc);
rgn->OffSet(-rc.left,-rc.top);

COLORREF HiColor,GrayColor,FaceColor;
HiColor=GetSysColor(SC_BUTTONHIGH);
GrayColor=GetSysColor(SC_BUTTONGRAY);
FaceColor=GetSysColor(SC_BUTTONFACE);

CBrush HiBrush,GrayBrush,FaceBrush;
HiBrush.CreateSolidBrush(Hicolor);
GrayBrush.CreateSolidBrush(Graycolor);
FaceBrush.CreateSolidBrush(FaceColor);

CBrush *OldBrush;

rgn.OffSet(-1,-1);
if(IsPush)
OldBrush=pDC->SelectObject(&GrayBrush);
else
OldBrush=pDC->SelectObject(&HiBrush);
pDC->DrawFrameRgn(rgn);
rgn.Offset(2,2);
if(IsPush)
pDC->SelectObject(&HiBrush);
else
pDC->SelectObject(&GrayBrush);
pDC->DrawFrameRgn(rgn);
rgn.OffSet(-1,-1);
pDC->SelectObject(&FaceBrush);
pDC->FillRgn(rgn);
pDC->SelectObject(OldBrush);
}
在OnLButtonDown中加上
Draw(true);
在OnLButtonUp中加上
Draw(false);
在OnPaint中加上
Draw(false);

程序信手而写，定有不少错误，有意与我联系，有源码([e-mail])
