Python Tkinter:窗格窗口不粘在顶部

Question

谢谢你花时间看这个。我已经挣扎了将近一个星期了，这让我发疯了。在

我有一个水平窗格窗口，它应该从工具栏底部延伸到窗口底部，但它只粘在根窗口的底部。最后，我希望在左窗格中有一个Treeview小部件，右窗格中有缩略图。在

谁能帮我把玻璃窗贴上NSEW吗？我需要把它放在另一个相框里吗？在

我在Windows7上使用Python2.7。（这不是我的整个程序，只是一个示例来演示问题。）

简短回答：按钮和工具栏框架之间的间距是因为允许包含工具栏的行而不是包含窗格窗口的行调整大小。。。要获得所需内容，请替换：

self.root.rowconfigure(0, weight=1)

与

其他评论：

• 尝试avoid wildcard imports。在这种情况下，很难区分tk和ttk小部件
• 要允许调整使用grid()对齐的小部件的大小，必须在小部件的父级而不是小部件本身上调用.rowconfigure(..., weight=x)。在
• 背景色对于调试tkinter中的对齐问题非常有用。在
