我正在将 GUI 应用程序从 PyQt4 转换为 PyQt5。但在 PyQt4 中,我们得到了很多 QStyle,例如 plastique
、Cleanlooks
等。但在 PyQt5 中,我们只有 Fusion
样式以及一些普通的旧 Windows 样式.
我们如何向 PyQt5 添加更多自定义样式?
最佳答案
Qt 的许多功能都是通过插件实现的,样式也是如此。所以在这种情况下你必须编译qtstyleplugins:
您可以使用以下过程来编译qtstyleplugins:
在 Windows 上安装 MSVC 2019,在 MacOS 上安装 XCode,在 Ubuntu 上安装 build-essential(如果是其他发行版,那么您应该寻找等效版本)。
安装 Qt,与编译 pyqt5 的版本相同:
python -c "from PyQt5.QtCore import QT_VERSION_STR; print('Qt version', QT_VERSION_STR)"
。克隆存储库,然后通过执行以下命令进行编译(如果是 Windows,则必须将 make 更改为 nmake):
git clone https://code.qt.io/qt/qtstyleplugins.git cd qtstyleplugins qmake make make install
这些命令将在文件夹“qtstyleplugins/plugins/styles/”中生成二进制文件(对于 Linux 为 .so,对于 Windows 为 .dll,对于 MacOS 为 .dylib),您必须将其复制到以下路径:
python -c "import os; from PyQt5 import QtCore; print(os.path.join(QtCore.QLibraryInfo.location(QtCore.QLibraryInfo.PluginsPath), 'styles'))"
输出:
/home/qtuser/Documents/qt_venv/lib/python3.8/site-packages/PyQt5/Qt/plugins/styles
为了方便工作,我创建了一个生成二进制文件的 github 操作:

您可以从 here 下载 pyqt5 5.15 的二进制文件.
测试:
python -c "from PyQt5 import QtWidgets; app = QtWidgets.QApplication([]); print(QtWidgets.QStyleFactory.keys())"
输出:
['bb10dark', 'bb10bright', 'cleanlooks', 'cde', 'motif', 'plastique', 'windowsvista', 'Windows', 'Fusion']
