Qt Designer 设计页面:
通过 PyQt5 手写
1. 先引入用到的库
python
from PyQt5.QtWidgets import *
import sys2. 创建应用,窗口, 设置窗口
python
# 创建应用
app = QApplication(sys.argv)
# 创建窗口
w = QWidget()
# 设置窗口标题
w.setWindowTitle("注册登录")
# 展示
w.show()
# 等待退出
sys.exit(app.exec())2. 设置性别和爱好的横向布局
python
# 横向布局
hSexLayout = QHBoxLayout()
hHobbyLayout = QHBoxLayout()4. 表单布局
python
# 表单
form = QFormLayout()
# 用户名
username = QLineEdit()
# 密码
password = QLineEdit()
# 将密码设置为密码属性
password.setEchoMode(password.Password)
# 性别
radioSex1 = QRadioButton("男")
radioSex2 = QRadioButton("女")
# 默认选中男
radioSex1.setChecked(True)
# 单选框添加到横向layout
hSexLayout.addWidget(radioSex1)
hSexLayout.addWidget(radioSex2)
# 爱好 复选框
hobby1 = QCheckBox("抽烟")
hobby2 = QCheckBox("喝酒")
hobby3 = QCheckBox("烫头")
# 复选框添加到横向layout
hHobbyLayout.addWidget(hobby1)
hHobbyLayout.addWidget(hobby2)
hHobbyLayout.addWidget(hobby3)
# 签名
signature = QLineEdit()
# 择偶要求: 多行输入框
choose = QTextEdit()
# 注册按钮
btn = QPushButton("确认注册")
btn.setFixedSize(120, 40)5. 向表单中添加每一行
python
# 表单
form.addRow("用户名", username)
form.addRow("密码", password)
form.addRow("签名", signature)
form.addRow("性别", hSexLayout)
form.addRow("爱好", hHobbyLayout)
form.addRow("择偶要求", choose)
form.addRow("", btn)6. 定义打印信息的方法
python
def printall():
print("用户名:", username.text())
print("密码:", password.text())
if radioSex1.isChecked():
print("性别: 男")
if radioSex2.isChecked():
print("性别: ", radioSex2.text())
hobby = []
if hobby1.isChecked():
hobby.append(hobby1.text())
# print("爱好:抽烟")
if hobby2.isChecked():
hobby.append(hobby2.text())
# print("爱好:喝酒")
if hobby3.isChecked():
hobby.append(hobby3.text())
# print("爱好:烫头")
print(hobby)
print("个性签名:", signature.text())
print("择偶要求:", choose.toPlainText())7. 布局添加容器,点击确认注册调用方法
python
btn.clicked.connect(printall)
# 布局添加到容器
w.setLayout(form)完整代码
python
from PyQt5.QtWidgets import *
import sys
app = QApplication(sys.argv)
w = QWidget()
# 设置窗口标题
w.setWindowTitle("注册登录")
# 横向布局
hSexLayout = QHBoxLayout()
hHobbyLayout = QHBoxLayout()
# 表单
form = QFormLayout()
# 用户名
username = QLineEdit()
# 密码
password = QLineEdit()
# 将密码设置为密码属性
password.setEchoMode(password.Password)
# 性别
radioSex1 = QRadioButton("男")
radioSex2 = QRadioButton("女")
# 默认选中男
radioSex1.setChecked(True)
# 单选框添加到横向layout
hSexLayout.addWidget(radioSex1)
hSexLayout.addWidget(radioSex2)
# 爱好 复选框
hobby1 = QCheckBox("抽烟")
hobby2 = QCheckBox("喝酒")
hobby3 = QCheckBox("烫头")
# 复选框添加到横向layout
hHobbyLayout.addWidget(hobby1)
hHobbyLayout.addWidget(hobby2)
hHobbyLayout.addWidget(hobby3)
# 签名
signature = QLineEdit()
# 择偶要求: 多行输入框
choose = QTextEdit()
# 注册按钮
btn = QPushButton("确认注册")
btn.setFixedSize(120, 40)
# 表单
form.addRow("用户名", username)
form.addRow("密码", password)
form.addRow("签名", signature)
form.addRow("性别", hSexLayout)
form.addRow("爱好", hHobbyLayout)
form.addRow("择偶要求", choose)
form.addRow("", btn)
def printall():
print("用户名:", username.text())
print("密码:", password.text())
if radioSex1.isChecked():
print("性别: 男")
if radioSex2.isChecked():
print("性别: ", radioSex2.text())
hobby = []
if hobby1.isChecked():
hobby.append(hobby1.text())
# print("爱好:抽烟")
if hobby2.isChecked():
hobby.append(hobby2.text())
# print("爱好:喝酒")
if hobby3.isChecked():
hobby.append(hobby3.text())
# print("爱好:烫头")
print(hobby)
print("个性签名:", signature.text())
print("择偶要求:", choose.toPlainText())
btn.clicked.connect(printall)
# 布局添加到容器
w.setLayout(form)
w.show()
sys.exit(app.exec())通过Qt Designer设计表单
在UI文件中保存登陆注册的UI, 右键通过外部工具 PyUIC生成.py文件
生成登陆注册.py中的内容

注意: 需要引入UI文件中的.py文件中的所有 *
from UI.login_register import *
python
from PyQt5.QtWidgets import *
import sys
from UI.login_register import *
class login_register(QWidget):
def __init__(self, parent=None):
super().__init__(parent)
# 1. 实例化Ui_Form()
self.form = Ui_Form()
# 2. 调用setupUi方法
self.form.setupUi(self)
# 调用init_ui方法
self.init_ui()
def init_ui(self):
self.form.pushButton.clicked.connect(self.click)
def click(self):
print("姓名:", self.form.username.text())
print("密码:", self.form.password.text())
if self.form.radio1.isChecked():
print("性别:", self.form.radio1.text())
if self.form.radio2.isChecked():
print("性别:", self.form.radio2.text())
if self.form.checkBox_1.isChecked():
print("爱好1:", self.form.checkBox_1.text())
if self.form.checkBox_2.isChecked():
print("爱好2:", self.form.checkBox_2.text())
if self.form.checkBox_3.isChecked():
print("爱好3:", self.form.checkBox_3.text())
print("个性签名:", self.form.signature.text())
print("择偶要求", self.form.textEdit.toPlainText())
if __name__ == '__main__':
app = QApplication(sys.argv)
w = login_register()
w.show()
sys.exit(app.exec())直接运行后看到的结果, 在文章的最上面
这个案例中需要注意:
将密码设置为密码属性
password.setEchoMode(password.Password)
2. 性别为单选, 爱好为多选, 择偶要求为多行文本
最后效果
打印结果
