基于GDI的简单界面框架

在工作中经常需要为C++的对话框绘制界面，特别是按钮和背景等需要使用图片重新制成，而且这些绘制出来的“控件”都需要对点击等操作进行响应。为了方便大量的类似操作，自己动手写了一个简单的类，可实现对类似“控件”接近自动化的管理。

主要的想法如下：

1、实现对图片的自动管理，主要是销毁。

2、简化在对话框类中反复填写的代码工作量。

3、需要考虑常用的几种不同的控件及工作模式。

4、需要考虑控件在对话框上绘制时的层次问题。

5、文本可调整字体。

6、即使有大量控件，也可方便的对任意控件消息进行接收和处理。

实际使用时，首先在目标对话框类中声明一个变量

cyfGUIPlus m_gui;

然后进行初始化设置

m_gui.Initialize(this, 10086, 9001);m_gui.SetDefaultFont(10, false, true, 254, 1, 1, 1);

设置相应的控件

Gdiplus::Bitmap *imgbackround = m_gui.LoadImg(IDR_PNG_DLG_MEMBER, "PNG");m_gui.PushBackround("背景", imgbackround, 0, 0);

Gdiplus::Bitmap *imgbtnlogin = m_gui.LoadImg(IDR_PNG_BTN_LOGIN, "PNG");m_gui.PushClickButton("登录按钮", imgbtnlogin, 77, 155, gui_clickbtn_modelthree);

在对话框的三个鼠标消息函数中进行加载

LRESULT memberDlg::OnNcHitTest(CPoint point){LRESULT nHitTest = CDialog::OnNcHitTest(point); return (nHitTest == HTCLIENT) ? HTCAPTION : nHitTest;}void memberDlg::OnSysCommand(UINT nID, LPARAM lParam){CDialog::OnSysCommand(nID, lParam);if(SC_MOVE == (nID &0xFFF0)){PostMessage(WM_NCLBUTTONUP, nID, lParam);}}void memberDlg::OnNcLButtonDown(UINT nHitTest, CPoint point){CDialog::OnNcLButtonDown(nHitTest, point);ScreenToClient(&point);m_gui.OnDlgDown(point);}void memberDlg::OnNcLButtonUp(UINT nHitTest, CPoint point){CDialog::OnNcLButtonUp(nHitTest, point);ScreenToClient(&point);m_gui.OnDlgUp(point);}void memberDlg::OnNcMouseMove(UINT nHitTest, CPoint point){CDialog::OnNcMouseMove(nHitTest, point);ScreenToClient(&point);m_gui.OnDlgMove(point);}

注意鼠标消息函数需要在消息队列中设置

ON_WM_NCHITTEST()ON_WM_SYSCOMMAND()ON_WM_NCLBUTTONDOWN()ON_WM_NCLBUTTONUP()ON_WM_NCMOUSEMOVE()

然后在对话框的绘制函数中加载（这里使用了双缓冲进行绘制）

void memberDlg::OnPaint(){CPaintDC DC(this);using namespace Gdiplus;CDC *pDC = GetDC();CDC memDC;CRect rect;HBITMAP mBitmap;BITMAPINFO bmi;memset(&bmi, 0, sizeof(bmi));GetWindowRect(rect);bmi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);bmi.bmiHeader.biWidth = rect.Width();bmi.bmiHeader.biHeight = rect.Height();bmi.bmiHeader.biPlanes = 1;bmi.bmiHeader.biBitCount = 32;bmi.bmiHeader.biCompression = BI_RGB;bmi.bmiHeader.biSizeImage = rect.Width() * rect.Height() * 4;mBitmap = CreateDIBSection(NULL, &bmi, DIB_RGB_COLORS, 0, 0, 0);memDC.CreateCompatibleDC(pDC);memDC.SelectObject(mBitmap);Graphics graphics(memDC.m_hDC);/************************************************************/m_gui.OnDlgDraw(&graphics);/************************************************************/DWORD dwExStyle = GetWindowLong(m_hWnd, GWL_EXSTYLE);if((dwExStyle &0x80000) != 0x80000){SetWindowLong(m_hWnd, GWL_EXSTYLE, dwExStyle^0x80000);}POINT ptWinPos={rect.left, rect.top};SIZE sizeWindow={rect.Width(), rect.Height()};POINT ptSrc={0, 0};BLENDFUNCTION Blend={0, 0, 255, 1};UpdateLayeredWindow(pDC, &ptWinPos, &sizeWindow, &memDC, &ptSrc, 0, &Blend, 2);DeleteObject(mBitmap);memDC.DeleteDC();ReleaseDC(pDC);}

最后在消息函数中处理收到的操作

LRESULT memberDlg::OnMessage(WPARAM wParam, LPARAM lParam){switch (wParam){case 9001:{char ctrl[50] = {0};m_gui.GetPostCtrl(ctrl, sizeof(ctrl));if (0 == strcmp(ctrl, "关闭按钮")){}if (0 == strcmp(ctrl, "登录按钮")){}if (0 == strcmp(ctrl, "记住密码按钮")){}if (0 == strcmp(ctrl, "自动登录按钮")){}if (0 == strcmp(ctrl, "忘记密码按钮")){}if (0 == strcmp(ctrl, "注册账号按钮")){}}break;}return 1;}

其实这个类没啥技术含量，但有了之后，至少自我感觉工作中方便了不少。还有很多不完善的地方，不过慢慢补充就是。
