我正在桌面环境中工作,我希望我的 QML 窗口作为我的主桌面窗口。我正在将 QML 与 PyQt5 集成。

这是我的代码

win.show()
window.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True)

我尝试在代码中添加 window.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True) 但它不起作用。我还尝试添加 Qt.Desktop 标志,但这也不起作用。第一次,它给了我错误 AttributeError: 'QQuickWindow' object has no attribute 'setAttribute'。在第二次尝试中,脚本成功运行,但窗口未打开。我认为这可能是因为另一个桌面窗口正在运行。因此,我使用我的用户名登录到另一个控制台,创建了一个 bash 文件来运行窗口管理器和桌面窗口,然后通过 startx/home/newtron/myscript 启动它。它打开了一个空白窗口。连鼠标都没有(可能是失败)。

有人可以帮我吗?

谢谢。

最佳答案

Qt::WA_X11NetWmWindowTypeDesktopQt::WidgetAttribute所以它只对 QWidget 有意义,并且 OP 似乎理解它,因为在尝试中它使用 QMainWindow 但问题是 QMainWindow 不显示 QML,所以这不是解决方案。

这个想法是在 QML 所在的位置创建一个 QWidget,因此在这种情况下有 2 种可能的解决方案:

  1. 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_())

    ma​​in.qml

    // ...
    ApplicationWindow {
    property var theme: String("#ffffff")
    property var focusColor: String('transparent')
    id: applicationWindow
    <b>visible: false</b>
    width: Screen.width
    // ...

  2. QQuickViewQWidget::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_())

    ma​​in.qml

    import QtQuick 2.12
    import QtQuick.Controls 2.12

    Rectangle {
    property var theme: String("#ffffff")
    property var focusColor: String('transparent')
    color: "#2d2b2b"

    Image {
    id: image
    anchors.fill: parent
    source: "../Pictures/Wallpapers/113844.jpg"
    fillMode: Image.PreserveAspectCrop
    }
    PropertyAnimation{
    id: themeOpen
    target: rectangle
    // ...
  3. QQuickWidget :

    import os
    import sys

    from PyQt5.QtCore import Qt, QUrl
    from PyQt5.QtWidgets import QApplication, QWidget
    from PyQt5.QtQuickWidgets import QQuickWidget

    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)

    widget = QQuickWidget()
    widget.resize(640, 480)

    def on_statusChanged(status):
    if status == QQuickWidget.Error:
    for error in view.errors():
    print(error.toString())
    sys.exit(-1)

    widget.statusChanged.connect(on_statusChanged)

    widget.setResizeMode(QQuickWidget.SizeRootObjectToView)
    engine = widget.engine()
    context = engine.rootContext()
    context.setContextProperty("main", engine)
    widget.setSource(url)
    widget.setWindowTitle(widget.tr("Muscovy"))
    widget.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True)
    widget.showMaximized()

    sys.exit(myApp.exec_())

    ma​​in.qml

    import QtQuick 2.12
    import QtQuick.Controls 2.12

    Rectangle {
    property var theme: String("#ffffff")
    property var focusColor: String('transparent')
    color: "#2d2b2b"

    Image {
    id: image
    anchors.fill: parent
    source: "../Pictures/Wallpapers/113844.jpg"
    fillMode: Image.PreserveAspectCrop
    }
    PropertyAnimation{
    id: themeOpen
    target: rectangle
    // ...
