如何在 PySimpleGUI 元素中创建一定比例的行高？

Question

我正在使用 PySimpleGUI 为应用程序创建前端。

作为界面的一部分，我在 Tab 元素上垂直排列了两个元素：一个 Table 和一个 Canvas。

我希望两个元素水平填充整个空间，但我希望表格垂直占据空间的 2/3，而画布占据另外 1/3。我尝试了各种方法来扩展和调整元素的大小，但它们都不可避免地占据了垂直空间的一半。

我正在 Windows 上开发应用程序，我相信底层工具包是 TK，所以也许有一种较低级别的方法可以工作。

感谢您的想法和建议。

参考Tkinter Pack() setting a ratio for expanding

在pack方法构建的PySimpleGUI下无法实现。

这是在 PySimpleGUI 下将几何管理器从 pack 更改为 grid 的黑客方法，但可见/不可见选项将不再起作用。

import PySimpleGUI as sg

headings = ['President', 'Date of Birth']
data = [
    ['Ronald Reagan', 'February 6'],
    ['Abraham Lincoln', 'February 12'],
    ['George Washington', 'February 22'],
    ['Andrew Jackson', 'March 15'],
    ['Thomas Jefferson', 'April 13'],
    ['Harry Truman', 'May 8'],
    ['John F. Kennedy', 'May 29'],
    ['George H. W. Bush', 'June 12'],
    ['George W. Bush', 'July 6'],
    ['John Quincy Adams', 'July 11'],
    ['Garrett Walker', 'July 18'],
    ['Bill Clinton', 'August 19'],
    ['Jimmy Carter', 'October 1'],
    ['John Adams', 'October 30'],
    ['Theodore Roosevelt', 'October 27'],
    ['Frank Underwood', 'November 5'],
    ['Woodrow Wilson', 'December 28'],
]

size = (480, 320)

font = ('Courier New', 11)
sg.theme('DarkBlue3')
sg.set_options(font=font)

layout = [
    [sg.Table(data, headings=headings, justification='left', expand_x=True, expand_y=True, key='-TABLE-')],
    [sg.Graph(size, (0, 0), size, background_color='green', expand_x=True, expand_y=True, key='-GRAPH-')],
]

window = sg.Window('Title', layout, resizable=True, finalize=True)
height = window['-TABLE-'].Widget.winfo_reqheight()//2
window['-GRAPH-'].Widget.configure(height=height)
width = window['-GRAPH-'].CanvasSize[0]
window['-GRAPH-'].CanvasSize = (width, height)
table = window['-TABLE-'].Widget.master.master
table.pack_forget()
graph = window['-GRAPH-'].Widget.master
graph.pack_forget()
table.grid(row=0, column=0, sticky=sg.tk.NSEW)
graph.grid(row=1, column=0, sticky=sg.tk.NSEW)
root = table.master
root.rowconfigure(0, weight=2)
root.rowconfigure(1, weight=1)
root.columnconfigure(0, weight=1)
# Size of Graph changed, maybe you need to update following arguments
# window['-GRAPH-'].change_coordinates(graph_bottom_left, graph_top_right)
window.read(close=True)

如果窗口不能调整大小，会容易得多，只需使用语句window = sg.Window(...)中的以下代码

window = sg.Window('Title', layout, finalize=True)
height = window['-TABLE-'].Widget.winfo_reqheight()//2
window['-GRAPH-'].Widget.configure(height=height)
width = window['-GRAPH-'].CanvasSize[0]
window['-GRAPH-'].CanvasSize = (width, height)
# Size of Graph changed, maybe you need to update following arguments
# window['-GRAPH-'].change_coordinates(graph_bottom_left, graph_top_right)
window.read(close=True)
