1. 首先编译openssl
2. 其次编译curl，但是一些模块是不用在curl支持就屏蔽

./configure --disable-shared --without-zlib --disable-ldap --disable-ldaps --with-ssl=/Users/xxx/libs/build/openssl/openssl-OpenSSL_1_0_2l-build/x86_64 --prefix=/Users/xxx/libs/macos-build/out
最新macos系统 编译curl 涉及到http2 dn2 等配置库

支持http3的具体编译步骤：

1. 专业投资者的必然选择：相较于Web方案，桌面客户端性能更好，大屏直观，更好的支持深度交互场景
2. 用户体验需求提升：传统投融资、金融交易软件界面设计老旧（如大智慧/同花顺），不符合现代审美和交互需求
3. 跨平台需求：国产操作系统平台、高端用户 MacOS需求(海外用户巨大)
4. 传统行业软件开发没落：传统MFC,Wxwidgets框架技术老旧，迭代巨慢，开发耗时耗力
5. Qt框架支持比较完善：插件化机制方便扩展、丰富的组件提升开发效率、跨平台机制灵活部署

这个文章的评论也很精彩，有不少惊喜

1.主要是mac平台的库依赖区别于windows
故在编译库的时候，可以提前指定rpath
复制代码QMAKE_LFLAGS += -Wl,-rpath,@loader_path/../,-rpath,@executable_path/../,-rpath,@executable_path/../Frameworks

复制代码mac平台：
#include <AppKit/AppKit.h>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
NSView* view = (NSView*)w.effectiveWinId();
NSWindow* window = ;
window.titlebarAppearsTransparent = YES;
window.backgroundColor = ;
w.show();
return a.exec();
}windows平台临时办法：

简洁的使用

复制代码QAction *button = ui->lineEdit->findChild<QAction *>("_q_qlineeditclearaction", Qt::FindDirectChildrenOnly);
if(button){
QCommonStyle style;
QIcon icon = style.standardIcon(QStyle::SP_ComputerIcon);
button->setIcon( icon );
}

或者
QList<QAction *> allPButtons = ui->lineEdit->findChildren<QAction *>();
foreach (QAction *var, allPButtons) {
if( !var->objectName().isEmpty()){
QCommonStyle style;
QIcon icon = styl ..

大部分情况下Qt的x86应用程序可以运行于M1的 Rosetta之上,但是当我们基于Qt的应用程序依赖仅仅支持Arm64架构的库时就无法链接通过了.当前时间点为2021年8月份Qt尚未提供支持M1的免费发布版本,Qt 6.2有一个Preview版本支持M1,但普通用户有使用期限,且Preview版本并不是稳定版用上去有风险.

Disable Scene Interaction
Event handling is responsible by a good part of the CPU usage by the QGraphicsView engine. At each mouse movement the view asks the scene for the items under the mouse, which calls the QGraphicsItem::shape() method to detect intersections. It happens even with disabled items. So, if you don't need your scene to interact with mouse events, you can set QGraphicsView::setIntenteractive(false). In my case, I had two modes in my tool (measurement and move/rotate) where t ..
