How to make python tkinter treeview widget to fill empty row and column spaces on grid?

问题

以下是您提供的代码的翻译部分：

  1. 我有一个窗口来显示多个树状视图小部件。当前，当我展开它时，树状视图下面有一些空白行空间，我不确定如何在展开窗口时动态填充下面的空白空间。我已经尝试调整 rowspan/columnspan 选项，但无法获得如下图所示的期望输出。我还在下面包含了一个可重现的代码用于测试我的程序。请帮助建议我需要进行哪些更改。谢谢！

如果您需要更多帮助或有其他问题，请随时提出。

I have a window to display multiple treeview widgets. Currently there are some empty row spaces below the treeview when I expand it and I'm not sure on how to fill the empty spaces below dynamically when I expand the window. I have tried adjusting the rowspan/columnspan options but could not get the desired output as described in image below. I have also included a reproduceable code below for testing my program. Please help to advise on which part I need to make changes. Thanks!

问题发现

  • frame_checkpd.rowconfigure(2, weight=1) 上的行号错误，应该是行 1。
  • parentframe.grid(column=0, row=1, columnspan=3, sticky='W') 上的粘性选项错误，应该是 'NSEW'。
  • 缺少 parentframe.rowconfigure(...) 和 parentframe.columnconfigure(...)。
  • 缺少 frame_tree.rowconfigure(...) 和 frame_tree.columnconfigure(...)。

以下是实现这些更改所需的代码：

  1. class tab_one(Frame):
  2.     def __init__(self, *args, **kwargs):
  3.         ...
  4.         parentframe = tk.LabelFrame(frame_checkpd, bd=0)
  5.         frame_checkpd.rowconfigure(1, weight=1)    ### 将行 2 改为行 1
  6.         frame_checkpd.columnconfigure(2, weight=1, )
  7.         parentframe.grid(column=0, row=1, columnspan=3, sticky='NSEW')  ### 将 'W' 改为 'NSEW'
  9.         # 父级树
  10.         parentframe.rowconfigure(1, weight=1) ### 添加
  11.         parentframe.columnconfigure(0, weight=1) ### 添加
  12.         ...
  13.         # 子级树
  14.         frame_tree.rowconfigure(0, weight=1)  ### 添加
  15.         frame_tree.columnconfigure(0, weight=1)  ### 添加
  16.         ...

结果：

Issues found

  • Wrong row number on frame_checkpd.rowconfigure(2, weight=1), it should be row 1.
  • Wrong sticky option on parentframe.grid(column=0, row=1, columnspan=3, sticky='W'), it should be 'NSEW'.
  • missing parentframe.rowconfigure(...) and parentframe.columnconfigure(...)
  • missing frame_tree.rowconfigure(...) and frame_tree.columnconfigure(...)

Below is the required changes to achieve it:

  1. class tab_one(Frame):
  2.     def __init__(self, *args, **kwargs):
  3.         ...
  4.         parentframe = tk.LabelFrame(frame_checkpd, bd=0)
  5.         frame_checkpd.rowconfigure(1, weight=1)    ### row 2 -> 1
  6.         frame_checkpd.columnconfigure(2, weight=1, )
  7.         parentframe.grid(column=0, row=1, columnspan=3, sticky='NSEW')  ### 'W' -> 'EW'
  9.         # PARENT TREE
  10.         parentframe.rowconfigure(1, weight=1) ### added
  11.         parentframe.columnconfigure(0, weight=1) ### added
