A simple sliding control CSLIDetAb class

Seeing some people in the forum need a universal sliding control, considering it, inheriting a CSLIDetAb class from CWND, implementing some demo functions.

Instructions:

1. #include "slideTab.h" // In the header file of the window class you need to use, the 2. cslideTab m_slideTab; // Declare a CSLIDetab member variable 3. m_slideTab.createTab (CRECT (-1, -1, 50 , 50), ID_slideTab, this); // Call CSLideTab :: CreateTab (CRECT & RCTAB, UINT NID, CWND * PWNDParent) method during window initialization, where id_slideTab is the control ID and needs to be defined in the resource file. 4. m_slideTab.SetHeight (400); // Set to expand down, expand the height of 400 or m_slideTab.SetWidth (400); // set to the right to unfold, the unfolded width is more than 400 or more only the last call is valid. 5. You can overload this type of DrawTab (CDC * PDC) virtual member function to achieve the required interface effect. Double buffers have been implemented inside, directly drawn on the PDC. SlideTab.h

SlideTab.h

#pragma once #include "atltypes.h" // CSlideTab typedef enum _SLIDE_TAB_ACTION {SLIDE_TAB_UP = -1, SLIDE_TAB_STOP, SLIDE_TAB_DOWN} SLIDE_TAB_ACTION; class CSlideTab: public CWnd {DECLARE_DYNAMIC (CSlideTab) public: CSlideTab (); virtual ~ CSlideTab (); protected: DECLARE_MESSAGE_MAP () public: void CreateTab (CRect & rcTab, UINT nID, CWnd * pWndParent); afx_msg void OnPaint (); afx_msg void OnMouseMove (UINT nFlags, CPoint point); virtual BOOL PreTranslateMessage (MSG * pMsg); public: static void CALLBACK OpenTab (UINT uID, UINT uMsg, DWORD dwUser, DWORD dw1, DWORD dw2); int SetHeight (int nHeight); int SetWidth (int nWidth); afx_msg BOOL OnEraseBkgnd (CDC * pDC); virtual void DrawTab (CDC * pDC ); AFX_MSG Void OnDestroy (); AFX_MSG Void Onmove (int X, int y); private: uint m_ntimerid; int m_nhem; slide_tab_action m_naction; crect m_rcwnd; BOOL M_FVERT;};
