基于Qt的数据管理系统
应用背景基于Qt的数据管理系统,对Qt的数据库进行了一次应用,对于Qt初学者学习开发数据库等技术有较强学习价值。。。。。。。关键技术setFixedSize(750, 500);
ui->stackedWidget->setCurrentIndex(0);
QSqlQueryModel *typeModel = new QSqlQueryModel(this);
typeModel->setQuery("select name from type");
ui->sellTypeComboBox->setModel(typeModel);
QSplitter *splitter = new QSplitter(ui->managePage);
splitter->resize(700, 360);
splitter->move(0, 50);
splitter->addWidget(ui->toolBox);
splitter->addWidget(ui->dailyList);
splitter->setStretchFactor(0, 1);
splitter->setStretchFactor(1, 1);
on_sellCancelBtn_clicked();
showDailyList();
ui->typeComboBox->setModel(typeModel);
createChartModelView();

在当今,流行的编程软件种类繁多,它们编程方便、易于维护,但是在与硬件直接打交道和编制系统软件时却束手无策,于是C语言就有了用武之地。C语言作为汇编语言与高级语言之间的一种过渡语言,兼有汇编语言的高效和高级语言的方便。 在通讯中,为了保证行运安全可靠,标准的串行口必须具有许多握手信号和状态信息。这是因为通讯的各个计算机CPU速度不一样(这会导致“错帧”)以及发送机发送数据速度比接收机接收速度快(这会导致“过冲”)。为解决这个问题,我们采用一个简单的握手信号,即发送机每次仅发送半个字节(低4位)的数据,而另外半个字节(高4位)则用来传送信息。我们可以对信息位(高4位)进行如下简单的编码:-today, the popularity of the wide variety of software programming, is easy to maintain, but to deal directly with the hardware and system software when compiled a loss, so there will be a C language battlefield. C language as the compilation and Advanced Language a transition between languages, both assembly language and the efficient high-level language convenience. In telecommunications, in order to ensure safe and reliable transport firms, the standard serial I must have shook hands with many signals and state information. This is because the various computer communications CPU speed is not the same (this would lead to "the wrong frame") and transmitter to send data faster than fa
