我有一个主窗口的三个主要部分，其中左侧（关键数据）应占据整个窗口的高度，而右侧数据应在顶部和底部之间划分。右下角的数据是相关的，但并不重要-这就是为什么我希望它不可对接/可关闭。
Qt documentation显示了C ++中的一个示例，但是由于我没有C ++经验，所以我不知道如何将其转换为python代码。
Qt Designer应用程序将用户限制为“左” /“右” /“上” /“下”，并且限制小部件的最大宽度不允许我占用未使用的空间（即不允许列表小部件位于左移以占据主窗口的整个高度）
编辑：长话短说，要使Qdockwidget进入右下角，您必须在其上方放置另一个停靠小部件（仍然限于Right / Left / Top / Bottom DockWidgetArea）。看完下面的eyllanesc答案后，我将发布两个解决方案。首先是他的代码的简化版本，然后是我最初发布的代码的修改版本。
上面提到的C ++示例中的Eyllanesc翻译：
from PyQt4 import QtCore, QtGui
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.resize(600, 600)
self.centralWidget = QtGui.QTextEdit()
self.setCentralWidget(self.centralWidget)
# Upper table widget
dock = QtGui.QDockWidget("Upper", self.centralWidget)
dock.setAllowedAreas(QtCore.Qt.RightDockWidgetArea)
self.tableWidget = QtGui.QTableWidget(dock)
self.tableWidget.setObjectName("tableWidget")
self.tableWidget.setColumnCount(6)
self.tableWidget.setRowCount(7)
for i in range(7):
item = QtGui.QTableWidgetItem()
self.tableWidget.setVerticalHeaderItem(i, item)
self.tableWidget.verticalHeaderItem(i).setText("Item " + str(i + 1))
for i in range(6):
item = QtGui.QTableWidgetItem()
self.tableWidget.setHorizontalHeaderItem(i, item)
dock.setWidget(self.tableWidget)
self.addDockWidget(QtCore.Qt.RightDockWidgetArea, dock)
# Lower table widget
