I declair CursorMouseDownCwgraph1/CursorMouseUpCwgraph1/CursorMouseMoveCwgraph1 functions in my app.
by they do not response. While I also declaired OnValueChangedCwbooleanLock and CursorChangeCwgraph1 and
they work well. It seems that there are no difference between the above two times of declairation as follows:
1, .h
protected:
// 自定义消息，2010-4-21
afx_msg LRESULT OnSelectedLineChanged(WPARAM wParam, LPARAM lParam);
// Cwgraph图像的光标处理函数。
afx_msg void CursorChangeCwgraph1(long* CursorIndex, VARIANT* XPos, VARIANT* YPos, BOOL* bTracking);
afx_msg void ValueChangedCwboolean1(BOOL Value);
afx_msg void PanCwgraph1();
afx_msg void ZoomCwgraph1();
afx_msg void CursorMouseDownCwgraph1(short* Button, short* Shift, VARIANT* XPos, VARIANT* YPos, short* CursorIndex, long* CursorPart);
afx_msg void CursorMouseMoveCwgraph1(short* Button, short* Shift, VARIANT* XPos, VARIANT* YPos, short* CursorIndex, long* CursorPart);
afx_msg void CursorMouseUpCwgraph1(short* Button, short* Shift, VARIANT* XPos, VARIANT* YPos, short* CursorIndex, long* CursorPart);
DECLARE_MESSAGE_MAP()
DECLARE_EVENTSINK_MAP()
2, .cpp
BEGIN_EVENTSINK_MAP(CResultView, CFormView)
ON_EVENT(CResultView, IDC_CWGRAPH1, 1, CResultView::CursorChangeCwgraph1, VTS_PI4 VTS_PVARIANT VTS_PVARIANT VTS_PBOOL)
ON_EVENT(CResultView, IDC_CWBOOLEAN1, 1, CResultView::ValueChangedCwboolean1, VTS_BOOL)
ON_EVENT(CResultView, IDC_CWGRAPH1, 16, CResultView::PanCwgraph1, VTS_NONE)
ON_EVENT(CResultView, IDC_CWGRAPH1, 15, CResultView::ZoomCwgraph1, VTS_NONE)
ON_EVENT(CResultView, IDC_CWGRAPH1, 4, CResultView::CursorMouseDownCwgraph1, VTS_PI2 VTS_PI2 VTS_PVARIANT VTS_PVARIANT VTS_PI2 VTS_PI4)
ON_EVENT(CResultView, IDC_CWGRAPH1, 2, CResultView::CursorMouseMoveCwgraph1, VTS_PI2 VTS_PI2 VTS_PVARIANT VTS_PVARIANT VTS_PI2 VTS_PI4)
ON_EVENT(CResultView, IDC_CWGRAPH1, 3, CResultView::CursorMouseUpCwgraph1, VTS_PI2 VTS_PI2 VTS_PVARIANT VTS_PVARIANT VTS_PI2 VTS_PI4)
END_EVENTSINK_MAP()
Moreover, How to use short* Button parameter in CursorMouseDownCwgraph1?
I go through Ni sample code "Multiple Cursors.2005" and so so, but don't find sample segment for CursorMouseDownCwgraph1/CursorMouseUpCwgraph1/CursorMouseMoveCwgraph1. Are there sample codes ?
