使用 pysimplegui 将按钮对齐到窗口的中心

Question

在我的应用程序中，我试图将我的按钮、文本和输入放在窗口的中心。我使用PySimpleGUI来设计按钮。为了对齐中心，我justification='center'在我的代码中使用了属性。但它仍然不适合中心窗户。

正在使用的代码是

import PySimpleGUI as sg
from tkinter import * 
sg.theme('DarkAmber')  
layout = [ 
        [sg.Text('Enter the value',justification='center')],
        [sg.Input(justification='center')],
        [sg.Button('Enter','center')]
     ]


  window = sg.Window('My new window', layout, size=(500,300), grab_anywhere=True)

 while True:
event, values = window.read()   # Read the event that happened and the values dictionary
print(event, values)
if event == sg.WIN_CLOSED or event == 'Exit':     # If user closed window with X or if user clicked "Exit" button then exit
    break
if event == 'Button':
  print('You pressed the button')
window.close()

上面的代码输出 如何将文本、按钮和输入置于窗口中心？

我想这就是你要找的

window = sg.Window('My new window', layout, element_justification='c')

编辑 - 垂直居中

在窗口中垂直居中布局是一件大事。需要的是 2 个元素，它们会在窗口展开时展开。这是一个演示程序，它是 PySimpleGUI GitHub 上演示的一部分

import PySimpleGUI as sg

"""
    Center a column in a window
    Solves a very specific kind of layout.
    If you want to have something centered in a Window, this is a good way to do it
    The "trick" here is:
        * the first row of the layout has a Text element that expands vertically
        * the row with the Column has a text element that expands horizontally
    
    This expanding Text element is what will cause the Column element to be centered

"""

def main():
    column_to_be_centered = [  [sg.Text('My Window')],
                [sg.Input(key='-IN-')],
                [sg.Text(size=(12,1), key='-OUT-')],
                [sg.Button('Go'), sg.Button('Exit')]  ]

    layout = [[sg.Text(key='-EXPAND-', font='ANY 1', pad=(0, 0))],  # the thing that expands from top
              [sg.Text('', pad=(0,0),key='-EXPAND2-'),              # the thing that expands from left
               sg.Column(column_to_be_centered, vertical_alignment='center', justification='center',  k='-C-')]]

    window = sg.Window('Window Title', layout, resizable=True,finalize=True)
    window['-C-'].expand(True, True, True)
    window['-EXPAND-'].expand(True, True, True)
    window['-EXPAND2-'].expand(True, False, True)

    while True:             # Event Loop
        event, values = window.read()
        print(event, values)
        if event == sg.WIN_CLOSED or event == 'Exit':
            break
        if event == 'Go':
            window['-OUT-'].update(values['-IN-'])
    window.close()

if __name__ == '__main__':
    main()

此代码使文本、按钮和输入位于窗口的中心。

import PySimpleGUI as sg
sg.theme('DarkAmber')  
layout = [ 
        [sg.Text('Enter the value',justification='center',size=(100,1))],
        [sg.Input(justification='center',size=(100,1))],
        [sg.Button('Enter','center',size=(100,1))]
     ]


window = sg.Window('My new window', layout, size=(500,300), grab_anywhere=True)

while True:
    event, values = window.read()   # Read the event that happened and the values dictionary
    print(event, values)
    if event == None or event == 'Exit':     # If user closed window with X or if user clicked "Exit" button then exit
        break
    if event == 'Button':
      print('You pressed the button')
    window.close()
