为什么执行Python QT5代码时不显示图标和图像？

Question

为什么执行Python QT5代码时不显示图标和图像？

Gau*_*tez 1 qt-designer python-3.x pyqt5

环境：

Python 3.7.7

Qt5

Qt 设计器 5.11

问题：

我使用 Qt Designer 设计了一个 GUI，并在按钮中的标签和图标背景中添加了一些图像。我可以从 Qt 设计器软件中正确看到图像和图标。但是当我执行 python 脚本来加载 UI 时，我再也看不到图像了。

代码：

我的主要 python 脚本位于根文件夹中，ui、qrc 和图像文件位于文件夹“ui”中：

main.py
ui/config.qrc
ui/doc.qrc
ui/document.png
ui/gear.png
ui/logo.qrc
ui/logo_MyUI_300.jpg
ui/MyUI.ui
ui/play-button.png
ui/play.png
ui/question.png
ui/quit.png
ui/quit.qrc
ui/report.qrc
ui/run.qrc
ui/save.png
ui/save.qrc
ui/scan.qrc
ui/search.png
ui/seo-report.png
ui/support.qrc
ui/telegram.png
ui/telegram.qrc
ui/watch_videos.qrc

uic.loadUi 函数与 Qt Designate 用于显示预览的方法不同，uic.loadUi 动态生成 python 允许的类和属性，因此它需要您使用 Pyrcc5 编译 rc 并将它们导入到脚本中，例如例子：

pyrcc5 ui/logo.qrc -o logo_rc.py

Run Code Online (Sandbox Code Playgroud)

from PyQt5 import QtWidgets, uic

import logo_rc

gui = QtWidgets.QApplication([])
ui=uic.loadUi('ui/MyUI.ui')

ui.show()
gui.exec()
