鼠标移动到CStatic上改变图标??

[Nirvana0]

我添加了一个基于CStatic类的新类,重载了
OnMouseMove方法
基本代码如:
CMyStatic.cpp
ON_WM_MOUSEMOVE()
...
void CMyStatic::OnMouseMove( UINT nFlags, CPoint point )
{
::SetCursor(AfxGetApp()->LoadCursor(IDI_ICON1));
或者
::SetCursor(LoadCursor(NULL, MAKEINTRESOURCE(IDI_ICON1)));
}
...

XXX.h
CStatic myStatic;

XXX.cpp
myStatic.Create(_T("测试"), SS_CENTER | SS_NOTIFY,CRect(50,80,305,125),this,IDS_TEST);
调试的时候鼠标移动到myStatic上的时候,能够进入OnMouseMove方法,但是鼠标的光标没有改变,为什么?

你要把它设成Notity

[Nirvana0]

myStatic.Create(_T("测试"), SS_CENTER | SS_NOTIFY(这里)
已经设了呀.

::SetCursor(AfxGetApp()->LoadCursor(IDI_ICON1));
或者
::SetCursor(LoadCursor(NULL, MAKEINTRESOURCE(IDI_ICON1)));

I think here you get some problems. Absolutely you use a ICON here. What you are supposed to set is a Cursor, but not a Icon!!!
You should import a file resource with the extended file name *.cur or *. ani, but not *.ico
Please check this factor!!!

Mark!!!

看看
HCURSOR h_icon = NULL;
h_icon= SetCursor( HCURSOR hCursor );
if(h_icon == NULL)
AfxMessageBox("failed");
else
AfxMessageBox("success");

如果没有对话框弹出，说明button没有接受到这个消息。

CStatic类似乎把WM_MOUSEMOVE消息给屏蔽了

[薛定谔之死猫]

模仿对话框上的超级链接，由CStatic类派生，参考了www.vckbase.com上的程序，中就有用到

BOOL CLinker::OnSetCursor(CWnd* pWnd,UINT nHitTest,UINT message)
{
if(t_hc==NULL)
{
t_hc=::LoadCursor(NULL,MAKEINTRESOURCE(32649));
}
::SetCursor(t_hc);
return FALSE;
}

整个类的代码粘给你算了，使用方法是在对话框上放一个CStatic的静态文本，然后在对话框中添加此类的成员，然后用该类subclassing CStatic对象窗口。

头文件：
#ifndef _LINKER_H
#define _LINKER_H

class CLinker:public CStatic
{
private:
CString m_strlink; //存储链接文件的路径(URL)
public:
DECLARE_DYNAMIC(CLinker)

CLinker();
void SetLinkObject(CString str); //设置链接文件的路径(URL)
~CLinker(){}
static COLORREF t_unvclr; //存储标题颜色
static COLORREF t_vdclr; //同上
static HCURSOR t_hc; //鼠标句柄
protected:
CFont m_font; //字体
COLORREF m_color; //实时标题颜色
DECLARE_MESSAGE_MAP()

afx_msg UINT OnNcHitTest(CPoint point);
afx_msg void OnLButtonDown(UINT nFlags,CPoint point);
afx_msg HBRUSH CtlColor(CDC* pDC,UINT nCtlColor);
afx_msg BOOL OnSetCursor(CWnd* pWnd,UINT nHitTest,UINT message);
};

}
}

UINT CLinker::OnNcHitTest(CPoint point)
{
return HTCLIENT; //返回客户区鼠标
}

HBRUSH CLinker::CtlColor(CDC* pDC, UINT nCtlColor)
{
ASSERT(nCtlColor==CTLCOLOR_STATIC);
DWORD dwStyle=GetStyle();
HBRUSH hbr=NULL;
if((dwStyle & 0xFF)<=SS_RIGHT) //判断是否为文本
{
if(!(HFONT)m_font)
{
LOGFONT lf;
GetFont()->GetObject(sizeof(lf),&lf);
lf.lfUnderline = TRUE; //可选择下划线字体
m_font.CreateFontIndirect(&lf);
}
pDC->SelectObject(&m_font); //应用字体
pDC->SetTextColor(m_color); //应用文本前景色
pDC->SetBkMode(TRANSPARENT); //背景为透明

hbr=(HBRUSH)::GetStockObject(HOLLOW_BRUSH);
}
return hbr;
}

BOOL CLinker::OnSetCursor(CWnd* pWnd,UINT nHitTest,UINT message)
{
if(t_hc==NULL)
{
t_hc=::LoadCursor(NULL,MAKEINTRESOURCE(32649));
}
::SetCursor(t_hc);
return FALSE;
}

使用例子：
link.SubclassDlgItem(IDC_STATICLINK,this);
