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:
