QtAds停靠系统中无法缩小侧边栏宽度的问题求助

我在Python中使用Qt配合QtAds实现基于停靠的UI，但无法缩小侧边栏（导航面板）的宽度。无论我用setMinimumWidth()还是resize()设置多少宽度，它都保持不变。

以下是我的最小可复现示例：

from qtpy import QtWidgets
from qtpy.QtWidgets import QGraphicsView, QMainWindow, QTreeWidget, QWidget, QPlainTextEdit

try:
    import PySide6QtAds as QtAds
except ImportError:
    from PyQtAds import QtAds

class MainWindow(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)

        self.dock_manager = None

        QtAds.CDockManager.setConfigFlag(QtAds.CDockManager.OpaqueSplitterResize, True)
        QtAds.CDockManager.setConfigFlag(QtAds.CDockManager.XmlCompressionEnabled, False)
        QtAds.CDockManager.setConfigFlag(QtAds.CDockManager.FocusHighlighting, True)
        self.showMaximized()

        self.dock_manager = QtAds.CDockManager(self)

        # Main working space
        central_widget1 = QtAds.CDockWidget("Tab 1")
        central_widget1.setWidget(QGraphicsView())
        self.dock_manager.addDockWidgetTab(QtAds.CenterDockWidgetArea, central_widget1)

        central_widget2 = QtAds.CDockWidget("Tab 2")
        central_widget2.setWidget(QPlainTextEdit())
        self.dock_manager.addDockWidgetTab(QtAds.CenterDockWidgetArea, central_widget2)

        # Results tab (hidden by default)
        result_widget = QtAds.CDockWidget("Result")
        result_widget.setWidget(QWidget())
        result_widget.setMinimumWidth(600)
        result_dock = self.dock_manager.addDockWidget(QtAds.DockWidgetArea.RightDockWidgetArea, result_widget)
        result_dock.hide()

        # Log Tab
        log_widget = QtAds.CDockWidget("Logs")
        log_widget.setWidget(QWidget())
        log_widget.setMinimumHeight(200)
        self.dock_manager.addDockWidget(QtAds.DockWidgetArea.BottomDockWidgetArea, log_widget)

        # Navigation Sidebar
        navigation_widget = QtAds.CDockWidget("Navigation")
        navigation_widget.setWidget(QTreeWidget())
        navigation_widget.setMinimumWidth(300)
        navigation_dock = self.dock_manager.addDockWidget(QtAds.DockWidgetArea.LeftDockWidgetArea, navigation_widget)
        navigation_widget.resize(500, navigation_widget.height())

        # Details sidebar
        details_widget = QtAds.CDockWidget("Details")
        details_widget.setWidget(QWidget())
        details_widget.setMinimumWidth(300)
        details_dock = self.dock_manager.addDockWidget(
            QtAds.DockWidgetArea.BottomDockWidgetArea, details_widget, navigation_dock
        )
        navigation_dock.resize(500, navigation_dock.height())
        details_dock.resize(500, details_dock.height())

if __name__ == '__main__':
    import sys

    app = QtWidgets.QApplication(sys.argv)
    app.setStyle("windowsvista")
    main_window = MainWindow()
    main_window.show()
    app.exec_()

我尝试过的方法：

• 设置setMaximumWidth(300)，但用户应该能够将其调宽。
• 使用resize(200, navigation_dock.height())，但宽度没有变化。

如何让QtAds中的侧边栏比默认宽度更窄？有没有办法设置初始宽度，以及窗口调整大小时的默认比例？

任何帮助都将不胜感激！
