qmake -project
qmake test.pro
#vim test.pro

#greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

mingw32-make

cd release
windeployqt test.exe

UI生成代码：
uic setup.ui -o ui_setup.h

qrc资源文件生成二进制文件
rcc --binary res.qrc -o skin.rcc

资源文件与代码分离
QResource::registerResource(qApp->applicationDirPath() + "/skin/skin.rcc");
    QFile file(":/qss/stylesheet");  
    if(file.open(QFile::ReadOnly))  
    {  
      QString strStyleSheet = file.readAll();  
      file.close();  
      qApp->setStyleSheet(strStyleSheet);  
    }
    
 
命令行输出：    
qDebug() << "Timer executed!";


提示框：
QMessageBox::information(this, "Title", "Hello");

QMessageBox::StandardButton reply;
reply = QMessageBox::question(this, "Title Here",
                                "Do you like cats?",
                                QMessageBox::Yes | QMessageBox::No);
if( reply == QMessageBox::Yes ){
    QMessageBox::information(this, "Title Here",
                             "You love cats!");
}else{
    QMessageBox::information(this, "Title Here",
                             "You don't like cats!");
}

QMessageBox::StandardButton reply;
reply = QMessageBox::question(this,
                              "Title Here",
                              "My text here",
                              QMessageBox::YesToAll | QMessageBox::Yes | QMessageBox::No | QMessageBox::NoToAll);
if( reply == QMessageBox::YesToAll ){
    QMessageBox::warning(this, "Title Here",
                         "Be careful");
}
