當點擊主按鈕 Window PyQt5 ZA7F5F35426B5274117Z9231
[英]Open Window when Clicked on Push Button in Main Window PyQt5 Python
問題描述
我已經瀏覽了有類似問題的各種類似帖子，也嘗試了答案，但它對我沒有用。 所以這是我的問題 -
I have two windows - TestBox and MailBox, when i click on the TestBox Pushbutton along with Input Path argument, it has to open the MailBox Window, This new window MailBox will send the ModifiedPath to the TestBox again when i closes the MailBox window
I have created both windows in PyQt5 Tool and created ui file and then converted to the Python file using - python -m PyQt5.uic.pyuic testboxui.ui -o testboxui.py
我沒有觸及 testboxui.py 或 mailboxui.py 文件，因為它們不斷更改通過重新轉換完成的任何修改。 相反，我創建了另一個文件 TestBox.py 和 MailBox.py 來導入和編寫函數。
這是可生產的最小代碼 -
TestBox.py [主要應用代碼]
import os,sys
from PyQt5 import QtWidgets, QtGui, QtCore
from testboxui import Ui_TestBox
from MailBox import AppWindow_MailList
app = QtWidgets.QApplication(sys.argv)
class AppWindow_MainBox(QtWidgets.QMainWindow):
def __init__(self):
super(AppWindow_MainBox, self).__init__()
self.ui = Ui_TestBox()
self.ui.setupUi(self)
self.ui.openbox.clicked.connect(self.fcn_maillist)
def fcn_maillist(self):
GetPath = os.getcwd()
dialog = AppWindow_MailList(self,GetPath)
if dialog.exec_() == AppWindow_MailList.Accepted:
GetPath = dialog.get_output()
def main():
app = QtWidgets.QApplication(sys.argv)
application = AppWindow_MainBox()
application.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
testboxui.py [由 PyQt5 工具直接從 UI 文件生成]
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_TestBox(object):
def setupUi(self, TestBox):
TestBox.setObjectName("TestBox")
TestBox.resize(647, 279)
self.centralwidget = QtWidgets.QWidget(TestBox)
self.centralwidget.setObjectName("centralwidget")
self.openbox = QtWidgets.QPushButton(self.centralwidget)
self.openbox.setGeometry(QtCore.QRect(210, 60, 231, 91))
self.openbox.setObjectName("openbox")
TestBox.setCentralWidget(self.centralwidget)
self.retranslateUi(TestBox)
QtCore.QMetaObject.connectSlotsByName(TestBox)
def retranslateUi(self, TestBox):
_translate = QtCore.QCoreApplication.translate
TestBox.setWindowTitle(_translate("TestBox", "TestBox"))
self.openbox.setText(_translate("TestBox", "Click Here \n""To Open Another Window"))
MailBox.py [子申請代碼]
import os,sys
from PyQt5 import QtWidgets, QtGui, QtCore
from maillistui import Ui_MailList
app = QtWidgets.QApplication(sys.argv)
class AppWindow_MailList(QtWidgets.QMainWindow):
def __init__(self,RcvPath=''):
super(AppWindow_MailList, self).__init__()
self.ui = Ui_MailList()
self.ui.setupUi(self)
self.init_fcn(RcvPath)
def init_fcn(self,RcvPath):
self.ui.browse.clicked.connect(self.browse_fcn)
if not RcvPath:
self.RcvPath = os.getcwd()
else:
self.RcvPath = RcvPath
self.ui.path.setText(self.RcvPath)
def closeEvent(self, event):
event.accept()
def get_output(self):
return os.path.join(self.RcvPath,'TestFolder')
def browse_fcn(self):
pass
def main():
app = QtWidgets.QApplication(sys.argv)
application = AppWindow_MailList()
application.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
maillistui.py - [由 PyQt5 直接從 ui 文件生成]
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MailList(object):
def setupUi(self, MailList):
MailList.setObjectName("MailList")
MailList.resize(647, 279)
self.centralwidget = QtWidgets.QWidget(MailList)
self.centralwidget.setObjectName("centralwidget")
self.path = QtWidgets.QLineEdit(self.centralwidget)
self.path.setGeometry(QtCore.QRect(50, 30, 511, 41))
self.path.setObjectName("path")
self.browse = QtWidgets.QPushButton(self.centralwidget)
self.browse.setGeometry(QtCore.QRect(450, 90, 112, 41))
self.browse.setObjectName("browse")
MailList.setCentralWidget(self.centralwidget)
self.retranslateUi(MailList)
QtCore.QMetaObject.connectSlotsByName(MailList)
def retranslateUi(self, MailList):
_translate = QtCore.QCoreApplication.translate
MailList.setWindowTitle(_translate("MailList", "MailList"))
self.browse.setText(_translate("MailList", "Browse"))
以前我曾經用 QtWidgets.QDialog 制作 PyQt5 對話框，我可以在 QtWidgets.QApplication 中輕松加載。 但是這里兩者都是 QApplication (QMainWindow) 但很難在 UI 中調用 ui。
我在這里做錯什么了嗎？？？

只應創建一個 QApplication ，在您的情況下，對於您不必要地創建 2 個腳本，請消除以下代碼：
```
from MailBox import AppWindow_MailList
app = QtWidgets.QApplication(sys.argv) # <--- delete this line
class AppWindow_MainBox(QtWidgets.QMainWindow):
```
```
from maillistui import Ui_MailList
app = QtWidgets.QApplication(sys.argv) # <--- delete this line
class AppWindow_MailList(QtWidgets.QMainWindow):
```
更正上述情況，出現另一個錯誤，但是對於這個 Python 指出錯誤消息，在許多 IDE 的情況下它們不處理 Qt 錯誤，所以我建議您在控制台中運行它，您將收到以下錯誤消息：
Traceback (most recent call last):
File "TextBox.py", line 16, in fcn_maillist
dialog = AppWindow_MailList(self,GetPath)
TypeError: __init__() takes from 1 to 2 positional arguments but 3 were given
這清楚地表明 AppWindow_MailList class 接受一個參數（ RcvPath ），但你傳遞了它 2。我不知道這是一個錯字還是你不知道在 python 中使用“self”（如果是后者，那么推薦閱讀“self”這個詞的目的是什么？ ）
class AppWindow_MailList(QtWidgets.QMainWindow):
def __init__(self,RcvPath=''):
super(AppWindow_MailList, self).__init__()
即使解決了這個錯誤，還有另一個問題，AppWindow_MailList 是一個 QMainWindow，所以它沒有任何 exec_() 方法，似乎你試圖使用一些使用 QDialog 的帖子的代碼而不了解解決方案的邏輯。
一般來說，每個小部件都有一個用途：
QWidget 是一個通用小部件，可用作構建任何其他類型的小部件或容器的基礎，類似於 html 中的 div。
QDialog 是一個小部件，其目的是向用戶請求信息，因此 exec_() 方法返回阻塞事件循環的請求狀態（如果它被接受或拒絕）。
QMainWindow 的目的是提供一個主要的 window，因為它包含工具欄、狀態欄、菜單欄、dockwidets 等。
因此，要實現您的目標，您必須選擇正確的元素，考慮到我將重組您的應用程序。
