duilib消息响应总结

Duilib类似MFC的消息响应如下：

DUI_DECLARE_MESSAGE_MAP()  
  
DUI_BEGIN_MESSAGE_MAP(CYmChatUI, CXMLWnd)  
    DUI_ON_MSGTYPE(DUI_MSGTYPE_CLICK, OnClick)  
DUI_END_MESSAGE_MAP()

绑定消息响应函数：

#define DUI_MSGTYPE_MENU                   (_T("menu"))  
#define DUI_MSGTYPE_LINK                   (_T("link"))  
  
#define DUI_MSGTYPE_TIMER                  (_T("timer"))  
#define DUI_MSGTYPE_CLICK                  (_T("click"))  
  
#define DUI_MSGTYPE_RETURN                 (_T("return"))  
#define DUI_MSGTYPE_SCROLL                 (_T("scroll"))  
  
#define DUI_MSGTYPE_DROPDOWN               (_T("dropdown"))  
#define DUI_MSGTYPE_SETFOCUS               (_T("setfocus"))  
  
#define DUI_MSGTYPE_KILLFOCUS              (_T("killfocus"))  
#define DUI_MSGTYPE_ITEMCLICK              (_T("itemclick"))  
#define DUI_MSGTYPE_TABSELECT              (_T("tabselect"))  
  
#define DUI_MSGTYPE_ITEMSELECT             (_T("itemselect"))  
#define DUI_MSGTYPE_ITEMEXPAND             (_T("itemexpand"))  
  
#define DUI_MSGTYPE_WINDOWINIT             (_T("windowinit"))  
#define DUI_MSGTYPE_BUTTONDOWN             (_T("buttondown"))  
#define DUI_MSGTYPE_MOUSEENTER             (_T("mouseenter"))  
#define DUI_MSGTYPE_MOUSELEAVE             (_T("mouseleave"))  
  
#define DUI_MSGTYPE_TEXTCHANGED            (_T("textchanged"))  
#define DUI_MSGTYPE_HEADERCLICK            (_T("headerclick"))  
#define DUI_MSGTYPE_ITEMDBCLICK            (_T("itemdbclick"))  
#define DUI_MSGTYPE_SHOWACTIVEX            (_T("showactivex"))  
  
#define DUI_MSGTYPE_ITEMCOLLAPSE           (_T("itemcollapse"))  
#define DUI_MSGTYPE_ITEMACTIVATE           (_T("itemactivate"))  
#define DUI_MSGTYPE_VALUECHANGED           (_T("valuechanged"))  
  
#define DUI_MSGTYPE_SELECTCHANGED          (_T("selectchanged"))

映射到的函数：

//定义消息类型--执行函数宏  
#define DUI_ON_MSGTYPE(msgtype, memberFxn)                                \  
    { msgtype, _T(""), DuiSig_vn, (DUI_PMSG)&memberFxn},                  \  
//定义消息类型--控件名称--执行函数宏  
#define DUI_ON_MSGTYPE_CTRNAME(msgtype,ctrname,memberFxn)                 \  
    { msgtype, ctrname, DuiSig_vn, (DUI_PMSG)&memberFxn },                \  
//定义click消息的控件名称--执行函数宏  
#define DUI_ON_CLICK_CTRNAME(ctrname,memberFxn)                           \  
    { DUI_MSGTYPE_CLICK, ctrname, DuiSig_vn, (DUI_PMSG)&memberFxn },      \  
//定义selectchanged消息的控件名称--执行函数宏  
#define DUI_ON_SELECTCHANGED_CTRNAME(ctrname,memberFxn)                   \  
    { DUI_MSGTYPE_SELECTCHANGED,ctrname,DuiSig_vn,(DUI_PMSG)&memberFxn }, \  
//定义killfocus消息的控件名称--执行函数宏  
#define DUI_ON_KILLFOCUS_CTRNAME(ctrname,memberFxn)                       \  
    { DUI_MSGTYPE_KILLFOCUS,ctrname,DuiSig_vn,(DUI_PMSG)&memberFxn },     \  
//定义menu消息的控件名称--执行函数宏  
#define DUI_ON_MENU_CTRNAME(ctrname,memberFxn)                            \  
    { DUI_MSGTYPE_MENU,ctrname,DuiSig_vn,(DUI_PMSG)&memberFxn },          \  
//定义与控件名称无关的消息宏  
  //定义timer消息--执行函数宏  
#define DUI_ON_TIMER()                                                    \  
    { DUI_MSGTYPE_TIMER, _T(""), DuiSig_vn,(DUI_PMSG)&OnTimer },          \

WindowImplBase也实现了一些常规消息的响应函数:

//点击事件  
virtual void OnClick(TNotifyUI& msg);  
//关闭窗口事件  
virtual LRESULT OnClose(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//销毁窗口事件  
virtual LRESULT OnDestroy(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//窗口尺寸改变时响应此事件  
virtual LRESULT OnSize(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);  
//拦截字符响应  
virtual LRESULT OnChar(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);  
//拦截系统消息响应  
virtual LRESULT OnSysCommand(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);  
//窗口创建时响应  
virtual LRESULT OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);  
//键盘按下时响应  
virtual LRESULT OnKeyDown(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//失去焦点时响应  
virtual LRESULT OnKillFocus(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//获得焦点时响应  
virtual LRESULT OnSetFocus(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//左键按下响应  
virtual LRESULT OnLButtonDown(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//左键抬起响应  
virtual LRESULT OnLButtonUp(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//鼠标移动响应  
virtual LRESULT OnMouseMove(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//鼠标滚轮响应  
virtual LRESULT OnMouseWheel(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& bHandled);  
//鼠标放在控件上响应  
virtual LRESULT OnMouseHover(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
