1.1.0 QLineEdit⼀些属性
inputMask设置掩码
text 设置⽂本
maxLength⽂本框输⼊的最⼤字符数
frame 设置边框
echoMode 设置⽂本框显⽰格式
Normal正常显⽰所输⼊的字符，此为默认选项
NoEcho不显⽰任何输⼊的字符，常⽤于密码类型的输⼊，且长度保密
Password显⽰与平台相关的密码掩饰字符，⽽不是实际输⼊的字符
PasswordEchoOnEdit在编辑时显⽰字符，负责显⽰密码类型的输⼊
cursorPosition光标位置
alignment⽂本对齐⽅式
AlignLeft左对齐
AlignRight右对齐
AlignCenter⽔平居中对齐
AlignJustify⽔平⽅向调整间距两端对齐
AlignTop垂直上对齐
AlignBottom垂直⽅下对齐
AlignVCenter垂直⽅向居中对齐
dragEnabled设置⽂本框是否接受拖动
readOnly设置⽂本为只读
placeholderText设置⽂本框提⽰⽂字
cursorMoveStyle光标移动风格
LogicalMoveStyle逻辑风格
VisualMoveStyle视觉风格
clearButtonEnabled快速删除按钮
1.1 常⽤的⼀些设置
setAlignment(self, Union, Qt_Alignment=None,Qt_AlignmentFlag=None): 设置字体对齐⽅式
参数作⽤
AlignAbsolute=16
AlignBaseline=256
AlignBottom=64底端对齐
AlignCenter=132完全居中
AlignHCenter=4⽔平居中

AlignLeft=1左对齐
AlignRight=2右对齐
AlignTop=32上对齐
AlignTrailing=2尾对齐(右对齐
AlignVCenter=128垂直居中
setClearButtonEnabled(self, bool): 是否有清除⽂本按钮(如我第⼀段程序⽂本框后的⼩⿊X) setCompleter(self, QCompleter)：设置⾃动补全
