如何使用 PyQt5 将 'Qt.WA_X11NetWmWindowTypeDesktop' 属性应用到我的 QML window
How to apply 'Qt.WA_X11NetWmWindowTypeDesktop' attribute to my QML window by using PyQt5
我在桌面环境中工作，我希望我的 QML window 作为我的主桌面 window。我正在将 QML 与 PyQt5 集成。
这是我的代码

我尝试在代码中添加 window.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True) 但它不起作用。我也尝试添加 Qt.Desktop 标志，但这也不起作用。第一次，它给我报错 AttributeError: 'QQuickWindow' object has no attribute 'setAttribute'。在第二次尝试中，脚本 运行 成功但 window 没有打开。我想可能是因为另一个桌面 window 是 运行ning。所以我用我的用户名登录到另一个控制台，创建了一个 bash 文件到 运行 window 管理器和 dektop window，然后通过 startx /home/newtron/myscript 启动它.它打开了一个空白window。连鼠标都没有（可能是失败）
有人可以帮我吗？
谢谢。
Qt::WA_X11NetWmWindowTypeDesktop is a Qt::WidgetAttribute 所以它只对 QWidget 有意义，而且 OP 似乎理解它，因为在它尝试使用 QMainWindow 但问题是 QMainWindow 不显示 QML 所以不是解决方案。
想法是在 QML 所在的位置有一个 QWidget，因此在这种情况下有 2 种可能的解决方案：
在ApplicationWindow中设置visible: false并使用QWidget::createWindowContainer():
import os
import sys
from PyQt5.QtCore import Qt, QUrl
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtQml import QQmlApplicationEngine
DIR_PATH = os.path.dirname(os.path.realpath(__file__))
if __name__ == "__main__":
myApp = QApplication(sys.argv)
file = os.path.join(DIR_PATH, "main.qml")
url = QUrl.fromLocalFile(file)
engine = QQmlApplicationEngine()
context = engine.rootContext()
context.setContextProperty("main", engine)
engine.load(url)
if not engine.rootObjects():
sys.exit(-1)
widget = QWidget.createWindowContainer(engine.rootObjects()[0])
widget.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True)
widget.showFullScreen()
sys.exit(myApp.exec_())
main.qml
// ...
ApplicationWindow {
property var theme: String("#ffffff")
property var focusColor: String('transparent')
id: applicationWindow
<b>visible: false</b>
width: Screen.width
// ...</pre>
QQuickView 与 QWidget::createWindowContainer():
import os
import sys
from PyQt5.QtCore import Qt, QUrl
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtQuick import QQuickView
DIR_PATH = os.path.dirname(os.path.realpath(__file__))
if __name__ == "__main__":
myApp = QApplication(sys.argv)
file = os.path.join(DIR_PATH, "main.qml")
url = QUrl.fromLocalFile(file)
view = QQuickView()
def on_statusChanged(status):
if status == QQuickView.Error:
for error in view.errors():
print(error.toString())
sys.exit(-1)
view.statusChanged.connect(on_statusChanged)
view.setResizeMode(QQuickView.SizeRootObjectToView)
engine = view.engine()
context = engine.rootContext()
context.setContextProperty("main", engine)
view.setSource(url)
view.setTitle(view.tr("Muscovy"))
widget = QWidget.createWindowContainer(view)
widget.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True)
widget.showMaximized()
sys.exit(myApp.exec_())

我尝试在代码中添加 window.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True) 但它不起作用。我也尝试添加 Qt.Desktop 标志，但这也不起作用。第一次，它给我报错 AttributeError: 'QQuickWindow' object has no attribute 'setAttribute'。在第二次尝试中，脚本 运行 成功但 window 没有打开。我想可能是因为另一个桌面 window 是 运行ning。所以我用我的用户名登录到另一个控制台，创建了一个 bash 文件到 运行 window 管理器和 dektop window，然后通过 startx /home/newtron/myscript 启动它.它打开了一个空白window。连鼠标都没有（可能是失败）
有人可以帮我吗？
谢谢。
Qt::WA_X11NetWmWindowTypeDesktop is a Qt::WidgetAttribute 所以它只对 QWidget 有意义，而且 OP 似乎理解它，因为在它尝试使用 QMainWindow 但问题是 QMainWindow 不显示 QML 所以不是解决方案。
想法是在 QML 所在的位置有一个 QWidget，因此在这种情况下有 2 种可能的解决方案：
在ApplicationWindow中设置
visible: false并使用QWidget::createWindowContainer():import os import sys from PyQt5.QtCore import Qt, QUrl from PyQt5.QtWidgets import QApplication, QWidget from PyQt5.QtQml import QQmlApplicationEngine DIR_PATH = os.path.dirname(os.path.realpath(__file__)) if __name__ == "__main__": myApp = QApplication(sys.argv) file = os.path.join(DIR_PATH, "main.qml") url = QUrl.fromLocalFile(file) engine = QQmlApplicationEngine() context = engine.rootContext() context.setContextProperty("main", engine) engine.load(url) if not engine.rootObjects(): sys.exit(-1) widget = QWidget.createWindowContainer(engine.rootObjects()[0]) widget.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True) widget.showFullScreen() sys.exit(myApp.exec_())main.qml
