在 PysimpleGUI 中根据输入值填写输入框

如何解决在 PysimpleGUI 中根据输入值填写输入框

这是我的代码：

import PySimpleGUI as sg
import datetime
from datetime import date
import pandas as pd

columns = ["TYPE","DIRECTION","DATE","OPTION"]
param = (20,3) # size of the main window

def GUI():
    sg.theme('Dark brown 1')
    listing = [sg.Text(u,size = param) for u in columns]
    core = [
    sg.Input(size = param),sg.Input(size = param),sg.Input(size = param)]
   
    mesh = [[x,y] for (x,y) in list(zip(listing,core))]
    layout =[[sg.Button("SEND")]]+ mesh
    window = sg.Window('Trade Entry System',layout,font='Courier 12').Finalize()
    
    
    while True:
        event,values = window.read()
        if event == "SEND":
            data = values
            a = list(data.values())
            df = pd.DataFrame(a,index = columns)
            df = df.transpose()
            print(df)

        else:
            print("OVER")
        break
    window.close()
GUI()

我想要做的是，例如，如果字符串 'STOCK' 输入到 TYPE 输入中，那么剩余的 3 个输入框应该填充预定义的值。例如，DIRECTION 填充'B'，日期填充'TODAY'，OPTION 填充'PUT'。

我不确定如何开始，所以任何帮助都会很棒

解决方法

在您的 enable_events=True 输入中设置选项 TYPE，它会在元素内容更改时生成事件，然后在元素内容等于 'STOCK' 时在您的事件循环中处理它。

import datetime
from datetime import date
import pandas as pd
import PySimpleGUI as sg


def GUI():

    columns = ["TYPE","DIRECTION","DATE","OPTION"]
    param   = (20,3) # size of the main window

    sg.theme('Dark Brown 1')
    sg.set_options(font=('Courier New',12))

    listing = [sg.Text(u,size = param) for u in columns]
    core = [
        sg.Input(size=param,enable_events=True,key='INPUT TYPE'),sg.Input(size=param),]
    mesh = [[x,y] for (x,y) in list(zip(listing,core))]

    layout = [[sg.Button("SEND")]] + mesh
    window = sg.Window('Trade Entry System',layout,finalize=True)

    while True:
        event,values = window.read()
        if event == sg.WINDOW_CLOSED:
            break
        elif event == "INPUT TYPE" and values[event] == "STOCK":
            for element,value in zip(core[1:],['B','TODAY','PUT']):
                element.update(value=value)

    window.close()

GUI()
