我正在使用PyQt5用Python编写密码程序,该程序也具有电子邮件功能。在该程序中,有2个窗口,第二个窗口的目标是向json文件添加一个新联系人。当我单击第二个窗口中的按钮时,该程序不会记录该点击。
作为第二个问题,我也很难将新的联系信息转储到文件中的正确位置。
这是我第二个窗口的代码:
class AddContactWindow(QtWidgets.QWidget):
def __init__(self):
super().__init__()
self.init_ui()
self.setStyleSheet(Window.StyleSheet1)
def init_ui(self):
self.TitleLab = QtWidgets.QLabel('Add New Contact')
self.NameLab = QtWidgets.QLabel('Name: ')
self.NameLe = QtWidgets.QLineEdit(self)
self.CodeNameLab = QtWidgets.QLabel('Code Name: ')
self.CodeNameLe = QtWidgets.QLineEdit(self)
self.EmailLab = QtWidgets.QLabel('Email address: ')
self.EmailLe = QtWidgets.QLineEdit(self)
self.KeyLab = QtWidgets.QLabel('Key: ')
self.KeyLe = QtWidgets.QLineEdit(self)
self.SubmitBtn = QtWidgets.QPushButton('Add Contact')
h_box = QtWidgets.QHBoxLayout()
h_box.addStretch()
h_box.addWidget(self.TitleLab)
h_box.addStretch()
h_box1 = QtWidgets.QHBoxLayout()
h_box1.addWidget(self.NameLab)
h_box1.addWidget(self.NameLe)
h_box2 = QtWidgets.QHBoxLayout()
h_box2.addWidget(self.CodeNameLab)
h_box2.addWidget(self.CodeNameLe)
h_box3 = QtWidgets.QHBoxLayout()
h_box3.addWidget(self.EmailLab)
h_box3.addWidget(self.EmailLe)
h_box4 = QtWidgets.QHBoxLayout()
h_box4.addWidget(self.KeyLab)
h_box4.addWidget(self.KeyLe)
h_box5 = QtWidgets.QHBoxLayout()
h_box5.addStretch()
h_box5.addWidget(self.SubmitBtn)
h_box5.addStretch()
v_box = QtWidgets.QVBoxLayout()
v_box.addLayout(h_box)
v_box.addLayout(h_box1)
v_box.addLayout(h_box2)
v_box.addLayout(h_box3)
v_box.addLayout(h_box4)
v_box.addLayout(h_box5)
self.setLayout(v_box)
self.setWindowTitle('Creat New Contact')
self.SubmitBtn.clicked.connect(self.submitBtn_click)
#self.SubmitBtn.clicked.connect(self.test)
self.show()
def test(self):
self.close()
def submitBtn_click(self):
print('Processing')
data = {}
data['Name'] = "New Contact Name"
data['CodeName'] = "New Code Name"
data['Email'] = "New Email Address"
data['Key'] = "TestKey"
with open('Contacts.json', 'a') as fp:
fp.seek(0, os.SEEK_END) # seek to end of file; f.seek(0, 2) is legal
fp.seek(fp.tell() -5, os.SEEK_SET) # go backwards 5 bytes
fp.write(", \n")
json.dump(data, fp, sort_keys=True, indent=4, separators=(',', ': '))
fp.close()
Window().__init__()
self.close()
这是我的所有文件:
任何帮助将不胜感激。

将第218行和219行之间的代码更改为:
self.hide()
AddContactWindow().exec_()
self.show()
self.ContactDropDown.clear()
self.ContactDropDown.addItem('Please select a contact')
with open('Contacts.json') as f:
self.ContactsFile = json.load(f)
for contact in self.ContactsFile['contacts']:
print(contact)
self.ContactDropDown.addItem(contact['Name'] + "/" + contact['CodeName'])
self.ContactDropDown.addItem("Add new contact")
将第297行中的代码更改为:
class AddContactWindow(QtWidgets.QDialog):
将368和375行之间的代码更改为:
ContactsFile = []
with open('Contacts.json', 'r') as fp:
ContactsFile = json.load(fp)
fp.close()
ContactsFile["contacts"].append(data)
with open('Contacts.json', 'w') as fp:
json.dump(ContactsFile, fp, sort_keys=True, indent=4, separators=(',', ': '))
fp.close()

您的代码有几个问题:
以下代码:submitBtn_click
没有意义,您正在创建一个新对象,并且您正在重置与刚刚创建的对象相同的对象,我怀疑您认为与此相关的是您正在重新加载初始窗口,但是。
另一方面,在import json

中,您正在重写数据,只有一个联系人丢失了初始格式,您应该做的是读取json,对其进行修改并保存。
您每次都在创建对象,但这不是最好的,最好是重用。在我的解决方案中,我仅创建每个类的一个窗口,然后根据需要关闭或显示这些窗口。
我看到的另一个问题是您没有正确使用布局。
考虑到前一件事,以及其他不那么先验的东西(由于我没有.txt,因此我没有使用keyCode,我认为您可以实现它)
while (resultSet.next()) {
Vector row = new Vector(columns);
for (int i = 1; i <= columns; i++) {
row.addElement(resultSet.getObject(i));
}
data.addElement(row);
}
