08 GDI练习

通过画一下表格练习GDI使用，函数都很简单，看名字就能知道用途，不懂的百度一下；直接贴效果图如下：

代码如下：

/*
 *HelloMFC.h
 */
#ifndef _HELLO_MFC_
#define _HELLO_MFC_

class CMyApp : public CWinApp{
public:
	virtual BOOL InitInstance();
};

class CMainWindow : public CFrameWnd{
public:
	CMainWindow();
	afx_msg void OnPaint();
	DECLARE_MESSAGE_MAP()
};

#endif

/*
 *HelloMFC.cpp
 */
#include <afxwin.h>
#include "HelloMFC.h"

CMyApp myApp;

BOOL CMyApp::InitInstance()
{
	m_pMainWnd = new CMainWindow;
	m_pMainWnd->ShowWindow(m_nCmdShow);
	m_pMainWnd->UpdateWindow();

	return TRUE;
}

BEGIN_MESSAGE_MAP(CMainWindow, CFrameWnd)
	ON_WM_PAINT()
END_MESSAGE_MAP()			  


CMainWindow::CMainWindow()
{
	Create(NULL, TEXT("画个表格"));
}

void CMainWindow::OnPaint()
{
	CPaintDC dc(this);
	CBrush brush;
	CString str;
	CRect rect(0, 0, 50, 30);
	brush.CreateStockObject(LTGRAY_BRUSH);
	dc.SelectObject(&brush);
	CRect rectTmp = rect;
	dc.SetBkMode(TRANSPARENT);
	for (int i = 0; i < 26; i++){
		dc.FillRect(&rectTmp, &brush);
		dc.Draw3dRect(&rectTmp, RGB(255, 255, 255), RGB(128, 128, 128));
		if (i != 0){
			str.Format(_T("%c"), 'A' + i - 1);
			dc.DrawText(str, &rectTmp, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
		}
		dc.MoveTo(rectTmp.right, 0);
		dc.LineTo(rectTmp.right, 30 * 20);
		rectTmp.left = rectTmp.right;
		rectTmp.right = rectTmp.right + 50;
	}
	rectTmp = rect;
	for (int i = 0; i < 20; i++){
		dc.FillRect(&rectTmp, &brush);
		dc.Draw3dRect(&rectTmp, RGB(255, 255, 255), RGB(128, 128, 128));
		if (i != 0){
			str.Format(_T("%d"), i - 1);
			dc.SetBkColor(RGB(128, 128, 128));
			dc.DrawText(str, &rectTmp, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
		}
		dc.MoveTo(0, rectTmp.bottom);
		dc.LineTo(50 * 26, rectTmp.bottom);
		rectTmp.top = rectTmp.bottom;
		rectTmp.bottom = rectTmp.bottom + 30;
	}

}
