双缓冲故障（使用小型演示源代码更新）

本文介绍了双缓冲故障（使用小型演示源代码更新）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我在主窗口中有一个复杂的绘画 WM_PAINT 处理程序。 我已经提交了一张图片来说明它： http://pbrd.co/18fNYYp [ ^ ] 主窗口有静态控件，而不是按钮，其样式为 SS_NOTIFY 。 当用户点击它们时，某些操作会在程序中发生，这与现在无关。 以下图片显示主窗口中静态控件的位置： http://pbrd.co/18fOkya [ ^ ] 地图上橙色面板是 EMF 文件，左上角和右上角徽标是 PNG 文件，以及其他图片ures是位图 s。 视觉样式是通过 #pragma 指令启用。我还使用 GDI + 以及 GDI 。 项目是作为空项目创建的，我已经从临时编码了所有内容。 为了实现这个任务，我决定绘制整个图片 WM_PAINT ，以及对图片上的图像放置透明静态控件。 为了保持我的代码干净简单，我已经制作了实现上述功能的函数，所以我的 WM_PAINT 处理程序可以很小尽可能。 使用 GradientFill（...） API制作渐变画笔。 /> 我在 Windows XP 上工作，使用 MS Visual Studio C ++ 2008 Express Edition 和 纯 Win32 API 。 一个音符：由于VS 的Express版本没有资源编辑器，因此创建了资源文件和资源头g ResEdit 从这里开始： http://www.resedit.net/。 [ ^ ] 为了让那些试图帮助的人更容易，这里是一个包含最少代码的单一源文件问题： http://pastebin.com/BeAVHViC [ ^ ] 为了避免闪烁，我使用了双缓冲，我从 Paul Watt 的文章中了解到， Charles Petzold的编程Windows第5版和 Forger的WIN32教程。 从理论上讲，一切正常，我的代码编译没有任何错误。 我在这里粘贴了代码： http：// pastebin.com/zSYT1i8L [ ^ ] 我的英语不够准确无法准确描述我所面临的问题（我只能说主窗口的边缘和静态控件重绘慢并且它们闪烁）所以我创建了一个演示应用程序来演示它们： http://www.filedropper.com/geotermistgrafika [ ^ ] 我已处理 WM_ERASEBKGND （已退回（LRESULT）1 ），我已经从我的窗口类中排除了 CS_VREDRAW 和 CS_HREDRAW 的样式 - 因此不应该因此导致闪烁。 我的窗口没有 WS_CLIPCHILDREN 样式，因为部分桌面图片在哪里静态控件是。 在我的 WM_SIZE 处理程序中我有： 使用 SetWindowPos（...） API重新定位静态控件，并通过添加 SWP_NOCOPYBITS 标志减少闪烁。 使用 InvalidateRect（hWnd，NULL，FALSE），所以这个API在无效时发送 WM_ERASEBKGND （第三个参数是 FALSE ），但即使我尝试使用 TRUE 效果相同。 我已经为 WM_PAINT 处理程序实现了双缓冲，就像上面的书/文章/教程中的示例一样（通过在内存DC中执行所有操作并在屏幕DC上执行 BitBlt（...）以避免闪烁）。 我没有处理 WM_SIZING ，也没有 WM_WINDOWPOSCHANGING 或 WM_MOVING 消息。 我使用了工具 GDIView （ http://www.nirsoft.net/utils/gdi_handles.html [ ^ ]）追踪 GDI泄漏。 每次我调整大小/最大化我的窗口， GDIView 在区域列中显示+4，这应该意味着我泄漏了区域，但我无法弄清楚这是如何可能的，因为我不使用操纵的API地区，并仔细检查了一切。 在我看来，一切都应该没问题，也许这是无关紧要的，但我只是想提一下，万一它很重要。 如果我在主窗口中添加 WS_EX_COMPOSITED 样式，性能不会提高。 我试图找到帮助我解决问题的在线示例，但所有教程都很简单，不包括这类复杂的图片。 重要提示： 在改进这个问题之前，我提出了两个解决方案，其中一个建议我做同样的事情因为我可以在 WM_ERASEBKGND 。 离开我的 WM_PAINT 处理程序为空并调用 onPaint 函数在 WM_ERASEBKGND 中，使用 GetDC（..） API获取设备上下文，闪烁消失，但在调整大小，重新绘制窗口是尖刻的，主窗口边缘的问题没有解决。 仍然，这比原始代码好得多。 更新（2013年12月17日）： 删除后从 onPaint 调用 drawImages（hdc，MemDC，r）; ，再次出现边缘闪烁。 /> 似乎更少了，区域数 GDIView 检测到泄漏减少了一个。 如何摆脱上面提供的演示应用程序中演示的问题？ 我特此感谢任何投入时间和精力去帮助我的人。 祝你好运。解决方案 CPallini是绝对正确的。使用WM_PAINT或OnPaint方法绘画会导致闪烁。使用WM_ERASEBKGND消息绘制大部分内容。 阅读一些关于为初学者绘画的文章。关键是要避免重绘。 http://www.codeproject.com/search.aspx?q=paint+for+beginners&x=-1262&y=-146&sbo=kw [ ^ ] 我通过迭代解决了这些问题：只绘制一块，如果有效，我将激活下一个只要它工作... 提示：不使用控件，但检查鼠标坐标并通过向窗口发送消息来处理它。 这是我用它做的。我离开了drawImages函数供你重写。 你应该可以使用CBitmap和CBitmap *而不会破坏你的代码。 #include resource.h #include < windows.h > #include < afxwin.h > #include < windowsx.h > // for TransparentBlt（） #include < commctrl.h > #include < gdiplus.h > #pragma comment（linker，/ manifestdependency：\type ='win32'\ name = ' Microsoft.Windows.Common-Controls' version = ' 6.0.0.0' \ processorArchitecture = ' *' publicKeyToken = ' 6595b64144ccf1df' \ language = ' *' \ ） #pragma comment（lib，comctl32.lib） #pragma comment（lib，Msimg32.lib）// for TransparentBlt（） #pragma comment（lib，Gdiplus.lib） 使用 命名空间 Gdiplus;

I also use GDI+ along with the GDI.Project was created as empty project and I have coded everything from "scratch".In order to implement this task, I have decided to draw the entire picture in WM_PAINT, and to put transparent static controls over the images on the picture that correspond them.In order to keep my code clean and simple, I have made functions that implement the above, so my WM_PAINT handler can be as small as possible.Gradient brushes were made with the usage of GradientFill(...) API.I work on Windows XP, using MS Visual Studio C++ 2008 Express Edition and pure Win32 API.One note: since Express edition of VS doesn't have resource editor, resource file and resource header were created using ResEdit from here: http://www.resedit.net/.[^]In order to make things easier for those trying to help, here is the single source file with minimal code that illustrates the problem: http://pastebin.com/BeAVHViC[^]In order to avoid flickering, I have used double buffering, which I have learned from Paul Watt’s articles, Charles Petzold’s Programming Windows 5th edition and Forger’s WIN32 tutorial.Theoretically speaking, everything is OK, and my code compiles without any errors.I have pasted the code here:http://pastebin.com/zSYT1i8L[^]My English is not good enough to accurately describe the problems that I face ( all I can say is that edges of the main window and static control's redraw "slow" and they flicker ) so I have created a demo application that demonstrates them:http://www.filedropper.com/geotermistgrafika[^]I have handled WM_ERASEBKGND ( returned (LRESULT)1 ), and I have excluded styles CS_VREDRAW and CS_HREDRAW from my window class-therefore flickering should not be caused because of this.My window doesn’t have WS_CLIPCHILDREN style because part of the desktop picture is seen where static controls are.In my WM_SIZE handler I have :Repositioned static controls using SetWindowPos(...) API and reduced flickering by adding the SWP_NOCOPYBITS flag. Invalidated the entire window with the InvalidateRect( hWnd, NULL, FALSE ), so this API does not send WM_ERASEBKGND when invalidating ( 3rd parameter is FALSE ), but even if I try with TRUE the effect is the same. I have implemented double buffering for WM_PAINT handler like in the examples found in the above books/articles/tutorials ( by doing everything in the memory DC and do BitBlt(...) on screen DC in order to avoid flickering ).I didn’t handle WM_SIZING, nor WM_WINDOWPOSCHANGING, or WM_MOVING message.I have used the tool GDIView ( http://www.nirsoft.net/utils/gdi_handles.html[^] ) to track down GDI leaks.Each time I resize/maximize my window, GDIView shows +4 in column for regions, which should mean that I leak regions but I can’t figure out how is this possible, since I do not use API’s that manipulate with regions, and have double checked everything.In my opinion everything should be fine and maybe this is irrelevant, but I just thought to mention it, in case it is important.If I add WS_EX_COMPOSITED style to the main window, the performance does not improve.I have tried to find online example that would help me to solve my problem but all the tutorials are simple and do not cover this type of complex pictures.IMPORTANT NOTE:Before improving this question, I got two solutions suggested, one of them advising me to do as much as I can in WM_ERASEBKGND. After leaving my WM_PAINT handler empty and calling onPaint function in WM_ERASEBKGND with the device context obtained with GetDC(..) API, the flickering disappeared, but during the resizing, redrawing of the window was "spiky" and the problem with the edges of the main window was not solved.Still, this is much better improvement than the original code.UPDATE ( December, 17th 2013 ): After removing the call drawImages( hdc, MemDC, r ); from onPaint, the flickering of the edges occurs again.It seems less, and the number of regions GDIView detects as leaked is reduced by one.How to get rid of the problems demonstrated in my demo application, provided above?I hereby thank anyone who invests its time and efforts to try to help me.Best regards. 解决方案 CPallini is absolutly right. Painting with WM_PAINT or the OnPaint method leads to flickering. Draw most things with the WM_ERASEBKGND message.read some articles about "paint for beginners". Key is to avoid redrawing.http://www.codeproject.com/search.aspx?q=paint+for+beginners&x=-1262&y=-146&sbo=kw[^]I solve these problem via iterating: only draw one piece and if it works, i activate the next as long as it work...Tip: dont work with controls, but check the mouse coordinates and handle it via posting messages to the windows.Here is what I did with it. I left the drawImages function for you to rewrite.You should be able to use CBitmap and CBitmap* without breaking your code.#include "resource.h"#include <windows.h>#include <afxwin.h>#include <windowsx.h> // for TransparentBlt()#include <commctrl.h>#include <gdiplus.h>#pragma comment( linker, "/manifestdependency:\"type='win32' \ name='Microsoft.Windows.Common-Controls' version='6.0.0.0' \ processorArchitecture='*' publicKeyToken='6595b64144ccf1df' \ language='*'\"")#pragma comment( lib, "comctl32.lib")#pragma comment( lib, "Msimg32.lib" ) // for TransparentBlt()#pragma comment( lib, "Gdiplus.lib" )using namespace Gdiplus;// variable for storing the instancestatic HINSTANCE hInst; // iconsstatic HICON hIcon, // main window's iconhiAdmin; // icon in the left corner of the status bar// Images for logosImage *image, // left logo on main window's top banner *image1, // right logo on main window's top banner *btn5; // map for the orange static control// variables for painting the windowstatic HBRUSH hbPozadina, // gray background brush for grid on the top BlueFrame, // needed to frame blue static controls hbr; // orange brush for orange panelstatic HBITMAP bmpBTN1, // image for top left blue static control bmpBTN2, // image for top right blue static control //============ these two make one image =========== // bmpBTN3, // left image for bottom left blue static control bmpBTN3a, // right image for bottom left blue static control //==================================================// bmpBTN4, // image for bottom right blue static control bmpSimbol, // middle logo on the main window's top banner bmpInfo, // top left image for child window of the 1st orange static control bmpLink, // top left image for child window of the 3rd orange static control bmpHelp; // top left image for child window of the 2nd orange static control/****************************** helper functions for WM_PAINT **************************/// Fills triangle with gradient brushvoid GradientTriangle( CDC* MemDC, LONG x1, LONG y1, LONG x2, LONG y2, LONG x3, LONG y3, COLORREF top, COLORREF bottom ){ TRIVERTEX vertex[3]; vertex[0].x = x1; vertex[0].y = y1; vertex[0].Red = GetRValue(bottom) << 8;vertex[0].Green = GetGValue(bottom) << 8;vertex[0].Blue = GetBValue(bottom) << 8;vertex[0].Alpha = 0x0000;vertex[1].x = x2;vertex[1].y = y2;vertex[1].Red = GetRValue(top) << 8;vertex[1].Green = GetGValue(top) << 8;vertex[1].Blue = GetBValue(top) << 8;vertex[1].Alpha = 0x0000;vertex[2].x = x3;vertex[2].y = y3; vertex[2].Red = GetRValue(bottom) << 8;vertex[2].Green = GetGValue(bottom) << 8;vertex[2].Blue = GetBValue(bottom) << 8;vertex[2].Alpha = 0x0000;// Create a GRADIENT_TRIANGLE structure that// references the TRIVERTEX vertices.
