自定义wxStaticBitmap的鼠标移动事件(或消息)

先在testwx1Main.cpp中定义一个函数如下,显示坐标:

void testwx1Frame::OnStaticBitmap1Move(wxMouseEvent& event)
{
    int X=event.GetX();
    int Y=event.GetY();
    TextCtrl1->SetLabel(wxString::Format(wxT("X:%i,Y:%i"),X,Y));
}

然后在头文件  testwx1Main.h 中声明这个函数:

void OnStaticBitmap1Move(wxMouseEvent& event);

接着在testwx1Frame类初始化函数里面,关联控件和消息函数:

testwx1Frame::testwx1Frame(wxWindow* parent,wxWindowID id)
{
    //...........................(*Initialize(testwx1Frame)
   
    StaticBitmap1->Connect(ID_STATICBITMAP1,wxEVT_MOTION,(wxObjectEventFunction)&testwx1Frame::OnStaticBitmap1Move,NULL, this);
}

有图有真相:
