如何使用 Python、PyQt5 和 Pyinstaller 修复未正确显示的按钮 [英] How to fix buttons not showing properly using Python, PyQt5, and Pyinstaller

问题描述

我使用 Qt Designer 创建了一个界面，并使用 PyQt5 将其集成到我的 Python 代码中.然后我使用 Pyinstaller 创建了一个 exe 文件，并且使用 Windows 10 Home 的笔记本电脑上的界面显示良好.然而，在使用 Windows 10 Pro 的不同 Windows 机器上进行测试显示按钮和标签全部被剪掉，字体错误，如下所示.例如，顶部标题应为 GEODISTANCE CALCULATOR，但仅显示GEODISTANCE CA".是什么导致这种不兼容，我该如何解决?

I created an interface using Qt Designer and integrated it into my python code using PyQt5. I then created an exe file using Pyinstaller and the interface shows up fine on my laptop using Windows 10 Home. However testing on a different windows machine using Windows 10 Pro shows the buttons and labels all cut out , with wrong font and all as shown below. For example, the top title should be GEODISTANCE CALCULATOR' but only shows 'GEODISTANCE CA'. What causes this incompatibility and how can I fix this?

我有下面的示例代码供任何想要测试样本的人使用:

I have the example code below for anyone who would like a sample to test on:

from PyQt5 import uic, QtWidgets
import sys

app = QtWidgets.QApplication(sys.argv)

window = uic.loadUi('interface.ui')
window.show()

sys.exit(app.exec_())

从Qt Designer派生的ui文件的完整代码如下所示，可以通过将代码复制粘贴到文本编辑器并将文件保存为'interface.ui'来重新创建该文件:

The complete code for the ui file derived from Qt Designer is as shown below and the file can be recreated by copying and pasting the code to a text editor and saving the file as 'interface.ui':

推荐答案

通过添加如下所示的多行代码解决了这个问题.有人已经发布了这个答案，但他们删除了它，可能认为它是错误的，因为我花了一段时间才将结果回复给他们，所以谢谢！

This issue is solved by adding a few more lines of code as shown below. Someone already posted this answer but they deleted it probably thinking its wrong as it took me a while to get back to them with the results, so thank you!

from PyQt5 import uic, QtWidgets
import sys

# Enable high DPI scaling
if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):
    PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)

if hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):
    PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)
app = QtWidgets.QApplication(sys.argv)

window = uic.loadUi('interface.ui')
window.show()

sys.exit(app.exec_())
