Pyqt 中下一页和上一页的问题
所以我目前正在做一个小项目,但我遇到了一个问题,我尝试过的所有方法都不起作用。我有 2 个文件: Page1test :
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QPushButton, QWidget, QLabel
import sys
from page2test import Page2
class Page1(QWidget):
def __init__(self):
super(Page1, self).__init__()
self.setWindowTitle("Page 1")
label1 = QLabel(self)
label1.setText("\n PAGE 1")
self.btn_inMyApp = QPushButton ('Next page', self)
self.btn_inMyApp.setGeometry(1500,800,275,125)
self.btn_inMyApp.clicked.connect(self.closePage1_OpenPage2)
self.show()
def closePage1_OpenPage2(self):
self.Open = Page2()
self.Open.showMaximized()
self.close()
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = Page1()
window.showMaximized()
sys.exit(app.exec_())
和 page2test :
from PyQt5.QtWidgets import QPushButton, QWidget, QLabel
from Page1test import Page1
class Page2(QWidget):
def __init__(self):
super(Page2, self).__init__()
self.setWindowTitle("Test window principale")
label1 = QLabel(self)
label1.setText("\n Page2")
self.btn_inMyApp = QPushButton ('previous Page', self)
self.btn_inMyApp.setGeometry(1500,800,275,125)
self.btn_inMyApp.clicked.connect(self.closePage2_OpenPage1)
self.show()
def closePage2_OpenPage1(self):
self.Open = Page1()
self.Open.showMaximized()
self.close()
我运行 Page1test 的代码:只有一个 Qpushbutton“下一页”的空窗口,目标:我们单击它,它打开第 2 页(并关闭第 1 页)。而且,当我们在第 2 页时,我们有一个带有“上一页”的 Qpushbutton,当我们单击它时,它会打开第 1 页,并关闭第 2 页。就像一个循环。 但是,当我运行代码时,它返回一个错误: 无法从部分初始化的模块“page2test”导入名称“Page2”(很可能是由于循环导入)
,我不知道如何修复它... 如果有人有一个想法,那将会非常有帮助。
so I'm currently working on a little project but I have an issue and all what I've tried did not work. I have 2 files :
Page1test :
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QPushButton, QWidget, QLabel
import sys
from page2test import Page2
class Page1(QWidget):
def __init__(self):
super(Page1, self).__init__()
self.setWindowTitle("Page 1")
label1 = QLabel(self)
label1.setText("\n PAGE 1")
self.btn_inMyApp = QPushButton ('Next page', self)
self.btn_inMyApp.setGeometry(1500,800,275,125)
self.btn_inMyApp.clicked.connect(self.closePage1_OpenPage2)
self.show()
def closePage1_OpenPage2(self):
self.Open = Page2()
self.Open.showMaximized()
self.close()
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = Page1()
window.showMaximized()
sys.exit(app.exec_())
And page2test :
from PyQt5.QtWidgets import QPushButton, QWidget, QLabel
from Page1test import Page1
class Page2(QWidget):
def __init__(self):
super(Page2, self).__init__()
self.setWindowTitle("Test window principale")
label1 = QLabel(self)
label1.setText("\n Page2")
self.btn_inMyApp = QPushButton ('previous Page', self)
self.btn_inMyApp.setGeometry(1500,800,275,125)
self.btn_inMyApp.clicked.connect(self.closePage2_OpenPage1)
self.show()
def closePage2_OpenPage1(self):
self.Open = Page1()
self.Open.showMaximized()
self.close()
I run the code of Page1test : empty window with just a Qpushbutton "Next Page", goal : we click on it and it open Page 2 (and close Page 1). And, when we are in Page 2, we have A Qpushbutton with "Previous Page" and when we click on it, it opens page 1, and close Page 2. Like a loop.
But, when I run the code, it returns an error :
cannot import name 'Page2' from partially initialized module 'page2test' (most likely due to a circular import)
and I have no idea how to fix it...
If someone had an idea, it would be really helpful.

所以,我终于找到了解决方案,最终并不是那么困难。就是这样(如果它可以帮助某人):
我没有制作 2 个文件,而是只制作了 1 个文件。这是代码:
So, I've finally found the solution, that was not so difficult in the end. Here it is (if it can help someone) :
Instead of making 2 files, I've done just 1 file. Here is the code :
