怎样做不规则按纽？

[xiaofk]

在vc中按纽缺省是方的，怎么做圆形或不规则的按纽，用MFC和不用MFC，只用api
怎样实现？？？

[jisheng]

用mfc嘛，呵呵，继承一个新按钮类，然后create。
纯api好象比较难了。

[rationalMath]

use WinAPI
SetWindowRGN
look out MSDN for detail

很多书中有现成例子

[tg123]

给你3角类
class CTriangleButton : public CButton
{
public:
enum POINTDIRECTION {POINT_UP, POINT_DOWN, POINT_LEFT, POINT_RIGHT};

// Construction
public:
CTriangleButton();
virtual ~CTriangleButton();

// Attributes
public:

protected:
POINTDIRECTION PointDirection;
CRgn CurrentRegion;

// Operations
public:

// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CTriangleButton)
public:
virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
protected:
virtual void PreSubclassWindow();
//}}AFX_VIRTUAL

public:
//note: SetWindowPos decreases the cx, cy parameter to nearest number dividable by two
BOOL SetWindowPos(const CWnd* pWndInsertAfter, int x, int y, int cx, int cy, UINT nFlags );

// Implementation
public:
void SetDirection(POINTDIRECTION PointDirection); //sets the direction of triangle
POINTDIRECTION GetDirection(); //gets the direction of triangle

// Generated message map functions
protected:
//{{AFX_MSG(CTriangleButton)
//}}AFX_MSG

DECLARE_MESSAGE_MAP()
};

[MoreBug]

在创建按钮时调用SetWindowRgn函数指定窗口形状.

[prog_st]

若需要，给例程！Email

[三水良子]

自己定义一个类，继承按钮类，重载drawim什么的函数，我计不清了，
