谢谢你做的这么好的一个lib，在win10上体验非常非常棒。
目前的实现依赖dwmapi.dll
而在win7 home basic版本里是没有这个dll的，所以在win7 home basic版本下用的时候，鼠标移动到关闭按钮上时会出现操作系统自带的关闭按钮。
我之前也写了一套qt frameless的解决方案，但是setContentMargins闪烁问题没办法解决，后来被否了。
在setResizeable(true)以后最小化、最大化和关闭按钮会重新出现。一般是在鼠标移动到窗口边框时重绘出的，请问怎样可以解决这个问题呢？
setResizeable(false)时不存在此情况。
Windows下我想实现自定义阴影
Qt5.5下设置属性setAttribute(Qt::WA_TranslucentBackground, true); 没问题
Qt5.9下设置该属性，提示下面错误
UpdateLayeredWindowIndirect failed for ptDst=(2560, 280), size=(296x250), dirty=(296x251 0, -1) (操作成功完成。)
你好， 在win7+qt5.8.0环境下，测试发现显示功能异常，是个空白面板，没有显示出任何按钮. 请问是什么原因导致的
你好，请问一下，我使用了 menuBar，然后把这个 menuBar 设置为窗口的“titleBar”，拖动 menuBar 可以控制窗口移动，但是怎么让 menuBar 里面的菜单可以响应？我试了事件过滤器也毫无反应。
// exampleforwindows/mainwindow.cpp 文件的开头部分
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QRect>
MainWindow::MainWindow(QWidget *parent) :
CFramelessWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
#ifdef Q_OS_WIN
//feel free to change this number to see how it works
setResizeableAreaWidth(8);
//set titlebar widget, wo we can drag MainWindow by it
// 删除titleBar，并在ui中把horizontalLayout拿出来放到一个dockWidget，
// 是为了下面可以把这一堆按钮放到menuBar中。
// setTitleBar(ui->widgetTitlebar);
setTitleBar(menuWidget()); // 让menuBar作为“标题栏”
menuWidget()->setLayout(ui->horizontalLayout); // 把一堆按钮放上去
// ......其他代码......
我将是将CFramelessWindow 继承自QWidget
然后设置
this->setAttribute(Qt::WA_ShowModal, true);
this->setWindowModality(Qt::ApplicationModal);
这部分代码 窗口的标题栏又出来了。
你好，在使用你的代码在MainWindow加入qquickwidget后，编译完成均无法绘制，就算load一个空的qml也一样，可能在渲染或者update有问题？
gif中窗口是圆角的，请问这个是如何实现的
when (Qt::AA_EnableHighDpiScaling) is enabled, after set the WindowsOS system custom scale to 125% / 150% / 200%， the dragable area of the framelesswindow titlebar breaks.
win+up/left/right没问题
这版本是QT4的么,QT5下没有setWindowFlag,改成setWindowFlags就出现了上面的问题
你好, 在该配置环境下， 最小化和最大化，退出按钮没有作用，点击的时候会闪现出默认的最小，最大化图标.
When maximizing the window, my secondary screen displays a grey vertical bar of about ten pixels on the side towards the other screen.
This happens only with showMaximized(), not showFullscreen().
If someone knows about this issue or even has a solution, I would appreciate a hint. I'm using Windows 10, Version 21H1. One monitor is 1920x1080px, the other 1680x1050px so there is some scaling involved.
Mac下有QOpenGLWidget的情况下把程序拖到另一个屏幕程序会出现4分之三的黑屏
Black rectangle is just 50x50 QOpenGLWidget.
Hold down the left mouse button press and hold the left mouse button to move the window to the second screen the release of the mouse, and then click on the title bar to move the window, can not move
Qt 5.11.1 + Win 10 1803，您的项目代码在此组合下没有无边框效果，您看看是出了什么问题。
使用了阴影后圆角很难实现。。。
Using the CFramelessWindow in my project, if I try to set a fixed window size or set the maximum window size at all, I can no longer move the window.
Can be recreated by opening a new project, importing the framelesswindow.h, framelesswindow.cpp, and framelesswindow.mm, then setting CFramelessWindow, then try either setting maximum window size in designer, or use something like setFixedSize(w,h).
你好，win7+qt5.8.0 +vs2013条件下， 按照两种载入方式， 鼠标放在右上角时都会出现系统默认的最小，最大，和退出图标. 请问是什么原因
我尝试把相关代码移植到Qt Quick窗口，在Win10上没问题。但在Win7上标题栏和边框还是显示出来了。似乎和OpenGL窗口有关。
Hi, thanks for your great job, I only have one problem
im trying to create a program with round corners
but the problem is look like your code add some kind of hover in window (as you can see White things in all four corner of window)
there is anyway to fix it??
thanks
G:\st_git\dragWindow\dragWinDemo\Qt-Nice-Frameless-Window\framelesswindow\framelesswindow.cpp:270: error: C2039: "getContentsMargins": 不是 "QMainWindow" 的成员
F:\QT_6.2\6.2.3\msvc2019_64\include\QtWidgets\qmainwindow.h(60): note: 参见“QMainWindow”的声明
窗口内存在OpenGLWidget时，标题栏显示位置出现错误
为什么在windows10上面跑显示的是mac的界面？有什么地方需要设置吗
win10开启自动隐藏任务栏后，
1、鼠标移入到屏幕最下排，会自动浮现出任务栏。
2、但Cframelesswindow最大化后，鼠标移入屏幕最下排，不会自动浮现出任务栏。
原因是在第一种情况下，软件最大化了，但最下排还是预留了2个像素。比如说屏幕分辨率是1366768。在这种情况下软件占据的屏幕像素为：1366766
但在第二种情况下，Cframelesswindow最大化后占据屏幕像素还是：1366*768
父窗口：parentDialog
子窗口：childDialog
第一种情况：
父窗口parentDialog使用以下方法创建子窗口
childDialog = new ChildDialog();//父窗口创建子窗口：没有指定了parent
父窗口parentDialog的事件处理方法nativeEvent，能接收到WM_GETMINMAXINFO、WM_NCCALCSIZE、WM_NCHITTEST消息
第二种情况：
父窗口parentDialog使用以下方法创建子窗口
childDialog = new ChildDialog(this);//父窗口创建子窗口：指定了parent
父窗口parentDialog的事件处理方法nativeEvent，不能接收到WM_GETMINMAXINFO、WM_NCCALCSIZE、WM_NCHITTEST消息
reproduce steps:
On WindowsOS:
CFramelessWindow* mainWin = new CFramelessWindow();
CFramelessWindow* subWin= new CFramelessWindow(mainWin );
these will break the dragable/resizeable feature of mainWin!
导入了framelesswindow.cpp文件之后发现缺少了<GdiPlusColor.h>，我下载了一个GDIPLUS文件，里面有一个include文件夹（包含了<GdiPlusColor.h>和很多其他的头文件）和一个lib文件夹（里面有一个GdiPlus.lib文件）请问有人清楚应该如何配置吗，是在visual studio中配置吗，还是通过Qt？我装的是visual studio 2017， Qt版本也是5.9.2。
Hi!
when the window returns to normal size from fullscreen state, the System Title Bar show again!
this issue has workground?
winId（） make resizeable donot work
win7系统下，当我把鼠标移动到右上角部分区域时，自定义的按钮可能就会失效，会被系统默认的三个按钮屏蔽，点击后就会针对相应区域出现系统默认的最小化、最大化或关闭按钮（如上图所示），有没有什么解决办法呢？（win10系统下却没有这个问题）
两个显示器分辨率不同
tried below compilers, this issue is always ocurr
win10升级1709之前，您的无边框窗口可以做到按住鼠标左键拖动窗口（不是拖标题栏），升级1709之后就不行了，不知道为什么。
Hi,
it looks like that the cpp contains only the windows implementation.
Besides that, good work!
您现在这个版本的代码仓库已经比我自己那个修改版的完善很多了，与其继续修补我那个定制版，还不如直接用您的来得划算，所以我就把我那个fork来的仓库删了，决定直接用您这个仓库。LICENSE我会保留的，您放心。
请问Linux系统下有什么较好的无边框窗口的实现方案吗？
Hi, I try to use your Nice Frameless Window, but with a QGraphicsView.
Indeed, the content of my MainWindow, is juste a QGraphicsView.
To be able to optimize the performance of my GraphicsView, I use an openGL Viewport with :
ui->graphicsView->setViewport(new QGLWidget(QGLFormat(QGL::SampleBuffers)));
When I add this line, then we can't move the MainWindows, and the "Hover" on button didn't work too.
Thanks
So glad to see this project solving the problem of customising window title bar using native ways for both macOS and Windows! And, from a Chinese friend :) 这个项目太棒了！
I had a quick test on Windows and found all worked well except one feature seemed missing. When we click the top left corner of a standard application window, it normally shows a system menu like this:
And this:
As shown above, Adobe Illustrator for Windows uses a custom window title bar and has the system menu.
Just wondering if it's possible to add the same support in this project?
