遇到怪问题了,请教! 我做了七个按钮,想改变按钮的颜色,结果运行时编译显示没有错误,运行的主界面却出不来,但如果只改变三个按钮的话却可以,第四个时主界面就出不来了,你们遇到过这种问题没有,是什么原因呢?(代码应该没有出错) 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 colorbtn.h文件:class CColorButton : public CButton{DECLARE_DYNAMIC(CColorButton)public: CColorButton(); virtual ~CColorButton(); BOOL Attach(const UINT nID, CWnd* pParent, const COLORREF BGColor = RGB(192, 192, 192), // gray button const COLORREF FGColor = RGB(1, 1, 1), // black text const COLORREF DisabledColor = RGB(128, 128, 128), // dark gray disabled text const UINT nBevel = 2 ); protected: virtual void DrawItem(LPDRAWITEMSTRUCT lpDIS); void DrawFrame(CDC *DC, CRect R, int Inset); void DrawFilledRect(CDC *DC, CRect R, COLORREF color); void DrawLine(CDC *DC, CRect EndPoints, COLORREF color); void DrawLine(CDC *DC, long left, long top, long right, long bottom, COLORREF color); void DrawButtonText(CDC *DC, CRect R, const char *Buf, COLORREF TextColor); COLORREF GetFGColor() { return m_fg; } COLORREF GetBGColor() { return m_bg; } COLORREF GetDisabledColor() { return m_disabled; } UINT GetBevel() { return m_bevel; }private: COLORREF m_fg, m_bg, m_disabled; UINT m_bevel;};#endif colorbtn.cpp文件:#include "stdafx.h"#include "colorbtn.h" #ifdef _DEBUG#undef THIS_FILEstatic char BASED_CODE THIS_FILE[] = __FILE__;#endif// no automatic class substitution for this file!#ifdef CColorButton#undef CColorButton CColorButton#endif// CColorButtonIMPLEMENT_DYNAMIC(CColorButton, CButton)CColorButton::CColorButton() { #if (_MFC_VER < 0x0250) hwndOwner = NULL; // initialize hwndOwner for GetOwner() and SetOwner() support in MFC < 2.5#endif } CColorButton::~CColorButton(){} BOOL CColorButton::Attach(const UINT nID, CWnd* pParent, const COLORREF BGColor, const COLORREF FGColor, const COLORREF DisabledColor, const UINT nBevel){ if (!SubclassDlgItem(nID, pParent)) return FALSE; m_fg = FGColor; m_bg = BGColor; m_disabled = DisabledColor; m_bevel = nBevel; return TRUE;} void CColorButton::DrawItem(LPDRAWITEMSTRUCT lpDIS){ CDC* pDC = CDC::FromHandle(lpDIS->hDC); UINT state = lpDIS->itemState; CRect focusRect, btnRect; focusRect.CopyRect(&lpDIS->rcItem); btnRect.CopyRect(&lpDIS->rcItem); // // Set the focus rectangle to just past the border decoration // focusRect.left += 4; focusRect.right -= 4; focusRect.top += 4; focusRect.bottom -= 4; // // Retrieve the button's caption // const int bufSize = 512; TCHAR buffer[bufSize]; GetWindowText(buffer, bufSize); // // Draw and label the button using draw methods // DrawFilledRect(pDC, btnRect, GetBGColor()); DrawFrame(pDC, btnRect, GetBevel()); DrawButtonText(pDC, btnRect, buffer, GetFGColor()); // // Now, depending upon the state, redraw the button (down image) if it is selected, // place a focus rectangle on it, or redisplay the caption if it is disabled // if (state & ODS_FOCUS) { DrawFocusRect(lpDIS->hDC, (LPRECT)&focusRect); if (state & ODS_SELECTED){ DrawFilledRect(pDC, btnRect, GetBGColor()); DrawFrame(pDC, btnRect, -1); DrawButtonText(pDC, btnRect, buffer, GetFGColor()); DrawFocusRect(lpDIS->hDC, (LPRECT)&focusRect); } } else if (state & ODS_DISABLED) { //COLORREF disabledColor = bg ^ 0xFFFFFF; // contrasting color DrawButtonText(pDC, btnRect, buffer, GetDisabledColor()); }} void CColorButton::DrawFrame(CDC *DC, CRect R, int Inset){ COLORREF dark, light, tlColor, brColor; int i, m, width; width = (Inset < 0)?
