PyQt5从入门到实践——Chapter5 PyQt5常用控件

概述
控件是窗口程序的基本组成单位，本章将对开发PyQt5窗口应用程序中经常用到的控件进行记录。
1. 控件概述
控件是用户可以用来输入或操作的对象。在PyQt5中，控件的基类是QFrame类，而QFrame类继承自QWidget类，QWidget类是所有用户界面对象的基类。
Qt Designer设计器中对控件进行了分组，下表是对各分组和控件的说明：
2. 文本类控件
2.1 Label：标签控件
（1）设置标签文本
（a）直接双击添加的Label控件直接修改（方便），或者修改text属性值
（b）代码实现方式：
self.label.setText("用户名:")（2）设置标签文本的对齐方式
（a）属性编辑器——alignment属性，分为Horizontal（水平）和Vertical（垂直）对齐方式
（b）代码实现方式：使用QLabel类的setAlignment，麻烦，懒得写了
（3）设置文本换行显示
（a）属性编辑器——wordWrap √
（b）代码实现方式：
self.label.setWordWrap(True)（4）为标签设置超链接
在QLabel类的setText()方法中使用HTML中的<a>标签设置超链接文本，并把Label标签的setOpenExternalLinks()方法设置为True
self.label.setText('<a href="https://www.csdn.net/">CSDN官网</a>') #CSDN官网为文本内容
self.label.setOpenExternalLinks(True)
#自定义链接样式使用style
#self.label.setText('<a style="text-decoration: none; color: black;" href="https://www.csdn.net/">CSDN官网</a>')
（4）为标签设置图片
使用QLabel类的setPixmap()方法
from PyQt5.QtGui import QPixmap
self.label.setPixmap(QPixmap("Chapter5/back.jpg"))2.2 LineEdit：单行文本框
（1）设置密码登录格式
实例：使用LineEdit+Label控件制作一个简单的登录窗口，其中限制密码为8位，并且以掩码形式显示。
步骤：
（a）Qt Designer设计窗口界面
（b）使用PyUIC工具转换为.py文件
（c）对密码输入框（lineEdit_2）进行设置
self.lineEdit_2.setEchoMode(QtWidgets.QLineEdit.Password) #设置为密码掩码
self.lineEdit_2.setValidator(QtGui.QIntValidator(10000000,99999999)) #设置为整数且限制位数完整代码：

if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
app.exit(app.exec_())2.3 TextEdit：多行文本框
显示多行文本内容，当文本内容超出控件的显示范围时将显示垂直滚动条。此外，不仅支持纯文本内容，也支持HTML网页。
实例：设置多行文本和HTML文本的对比显示
#设置纯文本显示
self.textEdit.setPlainText("与失败比起来，我对乏味和平庸的恐惧要严重得多。\n对我而言，很好的事情比糟糕的事情好，而糟糕的事情比平庸的事情好，因为糟糕的事情给生活添加了滋味 ")
#设置HTML文本显示
self.textEdit_2.setHtml("与失败比起来，我对乏味和平庸的恐惧要严重得多。\n对我而言，<font color='red' size = 12>很好的事情比糟糕的事情好，而糟糕的事情比平庸的事情好，</font>因为糟糕的事情给生活添加了滋味 ")

self.spinBox.setSingleStep(5) #步长为5实例：对SpinBox控件的范围和步长进行设置，并使用Label控件获取SpinBox中选择的数字（注意自定义GetValue()方法获取值）

3.1 PushButton：按钮
PushButton是最常用的按钮控件，前面已有例子使用过，当该控件被单击时看起来的状态像是被按下，然后释放。
实例：为用户登录系统添加“登录”和“退出”按钮，单击“登录”按钮时弹出用户输入的账号和密码，单击“退出”时则关闭当前窗口。

不能链接到内容？暂时不知道有什么用，有需要再补充
3.4 RadioButton：单选按钮
RadioButton控件常用的信号有两个：clicked（每次单击单选按钮就会发射），toggled（单选按钮状态改变时发射）。
实例：为3.1登录系统实例添加管理员登录和普通用户登录两种选择
