从 QTabWidget 拖放选项卡
Drag and drop tab from QTabWidget
我正在尝试从选项卡小部件中拖动一个选项卡并拆分查看区域(- 就像 eclipse 一样,然后您将选项卡标题拖动到编辑区域中 - 类似于选项卡上的 'split vertically' 功能在 PyCharm)。
我尝试使用拖放但无法让选项卡主区域(例如文本区域)注册来自 QTabBar 的拖动。然后我尝试只跟随鼠标移动并更进一步,但是拆分器代码不是很有效,而且它是非常难看的代码。
注意我没有使用可停靠小部件,因为此代码将用于应用程序的中央小部件。我更喜欢使用拖放来执行此操作 - 有人有任何想法吗?

但我不认为我在 parent 和 child 中央小部件中添加了正确的小部件。
这是我过去用过的一个技巧,可以满足您的需求。如果您想对参数进行大量控制,它可能会非常有限,但它可以完成工作。
- 将第 2 个
QMainWindow
作为 QMainWindow
中的 centralWidget
。
- 不要为第 2 个
QMainWindow
设置任何 centralWidget
。
设置标志:QMainWindow.AllowNestedDocks
和 QMainWindow.AllowTabbedDocks
通过添加 QDockWidgets
添加标签。这些将被自动威胁为 QTabWidgets
.
- 使用
QMainWindow.tabifyDockWidget(firstWidget,secondWidget)
以编程方式堆叠小部件(它可以多次用于超过 2 个小部件)
示例:
window=QtGui.QMainWindow()
window.centralContent=QtGui.QMainWindow()
window.setCentralWidget(window.centralContent)
window.centralContent.firstTabWidget=QtGui.QWidget()
window.centralContent.firstTabDock=QtGui.QDockWidget("first")
window.centralContent.firstTabDock.setWidget(window.centralContent.firstTabWidget)
window.centralContent.addDockWidget(window.centralContent.firstTabDock)
window.centralContent.secondTabWidget=QtGui.QWidget()
window.centralContent.secondTabDock=QtGui.QDockWidget("second")
window.centralContent.secondTabDock.setWidget(window.centralContent.secondTabWidget)
window.centralContent.addDockWidget(window.centralContent.secondTabDock)
window.centralContent.tabifyDockWidget( window.centralContent.firstTabDock, window.centralContent.secondTabDock)
