Qt在windows下和linux下使用WEB

由于在linux下没有QAxWidget ，但为了保证之前的Windows程序可以使用的，就需要将这两个分开
qt创建.pro文件

win32{
QT += core gui
QT += axcontainer
}
else
{
QT += core gui
QT += webenginewidgets
}
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
CONFIG += c++11
# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0
SOURCES += 
main.cpp 
mainwindow.cpp
HEADERS += 
mainwindow.h
FORMS += 
mainwindow.ui
# Default rules for deployment.

MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::resizeEvent(QResizeEvent *event)
{
/*随界面大小改变*/ ui->frame->setGeometry(this->frameGeometry().width()*0.1,this->frameGeometry().height()*0.1,this->frameGeometry().width()*0.8,this->frameGeometry().height()*0.8);
}

要在mianwindow.ui中添加一个QFrame
