@jsulm thx for replying Mr Jsulm，ive figured out， it wont take any futher effect after choosing 0x000000 in a QColorDialog，like choosing red is an invalid behavior once first choosing 0x000000,just same as painter of Windows

Thank you.

qrc文件最好不要重名，即便是不同的模块，会有一些覆盖问题

maybe you need '--qmldir' option

我遇见这个问题了，你怎么解决的了

数据库使用SSL连接，在debug运行时没有出现问题，但是在打包出现问题，程序运行出现找不到使用的key [ERROR] SSL error: Unable to get private key from 'client-key.pem' QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL"); if(db.isValid()) { //如果无数据库自动创建新的数据库 db.setConnectOptions("SSL_KEY=client-key.pem;SSL_CERT=client-cert.pem;SSL_CA=ca-cert.pem;CLIENT_IGNORE_SPACE=1"); db.setHostName("127.0.0.1"); db.setPort(53306); db.setUserName(""); db.setPassword(""); db.setDatabaseName(""); if (!db.open()) { qDebug()<< db.lastError().text(); QMessageBox::critical(nullptr, "错误信息", QString(db.lastError().text()), QMessageBox::Close); } }else { QMessageBox::critical(nullptr, "错误信息", QString(db.lastError().text()), QMessageBox::Close); }

That's not garbled. It's another form of phi. https://en.wikipedia.org/wiki/Phi#Computing I would look at the unicode sequence and the font. Also, try upgrading to a more recent release of Qt.
