[英]Add QStyles to Pyqt5
我正在將我的 GUI 應用程序從 PyQt4 轉換為 PyQt5。 但是在 PyQt4 中,我們得到了很多 QStyle,例如plastique
、 Cleanlooks
等。但是在 PyQt5 中,我們只有Fusion
樣式以及一些普通的舊 Windows ZBC4150D023D3255136DB671D61AC93F2。
我們如何將更多自定義 styles 添加到 PyQt5?
Qt 的許多功能都是通過插件實現的,styles 就是這種情況。 所以在這種情況下你必須編譯 qtstyleplugins:
您可以使用以下過程來編譯 qtstyleplugins:
在 MacOS 上的 Windows、XCode 上安裝 MSVC 2019 並在 Ubuntu 上安裝必要的構建(如果是另一個發行版,那么您應該尋找等效版本)。
Install Qt, the same version with which pyqt5 was compiled: python -c "from PyQt5.QtCore import QT_VERSION_STR; print('Qt version', QT_VERSION_STR)"
.
克隆存儲庫,然后通過執行以下命令對其進行編譯(對於 windows,您必須將 make 更改為 nmake):
git clone https://code.qt.io/qt/qtstyleplugins.git cd qtstyleplugins qmake make make install
這些命令將在文件夾“你必須復制到路徑:qtstyleplugins/plugins/style”中生成二進制文件(對於 Linux,.dll 對於 windows 和 MacOS 的 .dylib 路徑:
python -c "import os; from PyQt5 import QtCore; print(os.path.join(QtCore.QLibraryInfo.location(QtCore.QLibraryInfo.PluginsPath), 'styles'))"
Output:
/home/qtuser/Documents/qt_venv/lib/python3.8/site-packages/PyQt5/Qt/plugins/styles
為了方便工作,我創建了一個生成二進制文件的 github 操作:

您可以從此處下載 pyqt5 5.15 的二進制文件。
測試:
python -c "from PyQt5 import QtWidgets; app = QtWidgets.QApplication([]); print(QtWidgets.QStyleFactory.keys())"
Output:
['bb10dark', 'bb10bright', 'cleanlooks', 'cde', 'motif', 'plastique', 'windowsvista', 'Windows', 'Fusion']
