2、创建Radio_Button 

  • 1、多个radio button 在一个组里面 互斥
  • 2、使用Containers 容器把一类radio button放在一起
  • 3、选择radio button Text Broswer会有相应输出
  • 4、不同组内radio button选择时 绑定（组1 button1 和组2 button3绑定）

3、Input Widgets控件之发射携带参数信号的控件---Dail手轮（旋钮）、Scrool Bar（滑动条）

1、在Forms code generator 中选中 dail 的 on_dail_valueChanged(int)

2、手轮值 输出在LCD上

3、音量、亮度调节等

课后作业：通过旋钮和滑块控件 修改label 字体大小

 4、QT对话框

  • 通知对话框　　QMessageBox.information()

  • 　　程序运行时对用户操作进行反馈

  • 　　保存，提交，写入等操作成功

  • 询问对话框      QMessageBox.question()

    • 提醒用户是否进行某些操作

    • 关闭前是否保存？

    • 格式不兼容是否需要转换格式？

    • 是否跳转到相应界面？

  • 警告对话框     QMessageBox.warning()

    • 程序运行时产生的异常，提示用户注意

    • 非致命性错误

    • 一般情况下可以忽略

  • 严重警告对话框      QMessageBox.ctitical()

    • 程序运行时产生的严重错误或者异常

    • 不可忽略

    • 容易产生意想不到的结果，必须通知用户干预

  • 关于对话框    QMessageBox.about()

    • 一般是软件或者产品介绍

    • 多为文字性描述，界面简单

    •  

  •  AboutQt对话框      QMessageBox.aboutQT()
    • 　　Pyqt内置的Qt介绍对话框

class15+16  课后练习

使用button，label和单行文本框控件，计算表达式，引发一个异常，通过严重警告框通知用户

难点： 计算时出错显示   argument 1 has unexpected type 'float'

5、运行时获取用户输入 获得一个界面

 

# 后面四个数字的作用依次是 初始值 最小值 最大值 小数点后位数
　　doubleNum,ok1 = QInputDialog.getDouble(self, "标题","计数:", 37.56, -10000, 10000, 2)
#后面四个数字的作用依次是 初始值 最小值 最大值 步幅
　　intNum,ok2 = QInputDialog.getInt(self, "标题","计数:", 37, -10000, 10000, 2)
#第三个参数可选 有一般显示 （QLineEdit.Normal）、密碼显示（ QLineEdit. Password）与不回应文字输入（ QLineEdit. NoEcho）
　　stringNum,ok3 = QInputDialog.getText(self, "标题","姓名:",QLineEdit.Normal, "王尼玛")
#1为默认选中选项目，True/False  列表框是否可编辑。
　　items = ["Spring", "Summer", "Fall", "Winter"]
　　item, ok4 = QInputDialog.getItem(self, "标题","Season:", items, 1, True)
　　text, ok5 = QInputDialog.getMultiLineText(self, "标题", "Address:", "John Doe\nFreedom Street")

 

 

 

我曾经跨过山和大海，也穿过人山人海，我曾经拥有着的一切，转眼都飘散如烟，我曾经失落失望失掉所有方向，直到看见平凡才是唯一的答案。
