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();

本实验完成发光二极管的循环点亮实验,由于输入晶振为20M,分频得到count1信号,故每间隔约1S彩灯循环移位一次。
也可以外接32768hz的晶振经4060分频后的1HZclk输入,自己可以尝试改变实验,加以练习。
现象:可以看到流水灯-In this experiment completed the cycle of light-emitting diode light experiments, as a result of the importation of crystal for the 20M, sub-frequency signal received count1, so each interval of about 1S Lantern a cyclic shift. Can also be the external 32768Hz crystal oscillator frequency by 4060 after 1HZclk input, they can try to change the experiment, to practice. Phenomenon: we can see water lights
