pysimplegui 中的交互式弹出窗口 window

Question

我创建了一个 UI 预测，看起来像这样

代码是：

items = [
    "Automobile", "Chemical", "Engineering/Consulting", "FMCG",
    "Healthcare/Hospitality", "Infrastructue", "IT/Comm/DC", "Manufacturing",
    "Mines", "Energy/Oil & Gas", "Pharma", "Retail", "Cement",
]
length = len(items)
size = (max(map(len, items)), 1)

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

column_layout = []
line = []
num = 4
for i, item in enumerate(items):
    line.append(sg.Button(item, size=size, metadata=False))
    if i%num == num-1 or i==length-1:
        column_layout.append(line)
        line = []

layout = [
    [sg.Text('Choose the Industry')],
    [sg.Column(column_layout)],
    [sg.Text(size=(50,1),key=('loaded'))],
    [sg.Text('Enter Observation/Recommendation: ', size =(26, 1)), sg.InputText(do_not_clear=False)],
    [sg.Button("Predict Risk", bind_return_key=True,metadata=False)],
    [sg.Text(size=(30,1),key=('output'))],
    [sg.Text('If the above prediction is correct select \'yes\' else select the correct risk.')],
    [sg.Button("Yes"),sg.Button("Low"),sg.Button("Medium")],
    [sg.Text(size=(30,2),key=('trained'))],
    [sg.Button("Exit"),sg.Button("Clear Fields")]
]

window=sg.Window("Risk Predictor", layout, use_default_focus=False, finalize=True)
for key in window.key_dict:    # Remove dash box of all Buttons
    element = window[key]
    if isinstance(element, sg.Button):
        element.block_focus()

#window=sg.Window("Risk Predictor",layout)

while True:
    event, values = window.read()
    # End program if user closes window or
    if event == sg.WIN_CLOSED or event == 'Exit':
        break
    if event == "Mines":
        window['Mines'].metadata = True
        
        df=pd.read_csv('./Audit data_Observation & Risk.csv')
        #df1=balancing(df)
        df1=df
        window['loaded'].update("Mines data is loaded.")
        obs=values[0]
        #if obs!="":
    if event == "Predict Risk" and window["Mines"].metadata and values[0]!="":
        with open("./sgd.pickle", 'rb') as f:
            sgd = pickle.load(f)
        window['trained'].update("")
        output=output_sample(df1,sgd,values[0])
        output1="The Risk prediction is "+output
        window['output'].update(output1)
        window['Predict Risk'].metadata=True
    if event == 'Yes' and window['Predict Risk'].metadata==True:
        newy=preprocess_text(output)
        retrain(df1,values[0],newy)
        window['trained'].update("The model has been trained on new data.")
        continue
    elif event =='Low' and window['Predict Risk'].metadata==True:
        newy="Low"
        retrain(df1,values[0],newy)
        window['trained'].update("The model has been trained on updated data.")
        continue
    elif event =='Medium' and window['Predict Risk'].metadata==True:
        newy="Medium"
        retrain(df1,values[0],newy)
        window['trained'].update("The model has been trained on updated data.")
        continue
    if event=='Clear Fields':
        window['loaded'].update("")
        window['output'].update("")
        window['trained'].update("")
        values[0]=''
        window[event].metadata=False
        window['Predict Risk'].metadata=False
window.close()

它无论如何都还没有完成。我想把这个 UI 分成三个部分。

当应用程序是运行只有 Choose the industry 部分来了。
选择 Industry 后，弹出窗口会打开 Enter the Observation 和 Predict Risk。
单击 Predict Risk 时，另一个弹出窗口会显示预测和反馈机制。

所以我的问题是如何制作交互式弹出窗口？

Answer 1

只需在您的函数中创建一个带有 modal=True 的新 window，并传递参数和 return 您需要的值。选项 modal=True 如果为 True，则此 window 将是唯一 window 用户可以与之交互的对象，直到它关闭。

之前window的设置modal=True将被移除，所以最好只同时存在两个windows。当然，更多windows也可以，但需要更多的设置。

演示代码在这里，

import PySimpleGUI as sg

def block_focus(window):
    for key in window.key_dict:    # Remove dash box of all Buttons
        element = window[key]
        if isinstance(element, sg.Button):
            element.block_focus()

def popup_predict_risk(industry):

    col_layout = [[sg.Button("Predict Risk", bind_return_key=True), sg.Button('Cancel')]]
    layout = [
        [sg.Text(f"Industry: {industry}")],
        [sg.Text('Enter Observation/Recommendation: '), sg.InputText(key='Observation')],
        [sg.Column(col_layout, expand_x=True, element_justification='right')],
    ]
    window = sg.Window("Predict Risk", layout, use_default_focus=False, finalize=True, modal=True)
    block_focus(window)
    event, values = window.read()
    window.close()
    return values['Observation'] if event == 'Predict Risk' else None

def popup_prediction(industry, observation):

    col_layout = [[sg.Button('OK')]]
    layout = [
        [sg.Text("Here's the result\n")],
        [sg.Text(f"industry   : {industry}")],
        [sg.Text(f"Observation: {observation}")],
        [sg.Column(col_layout, expand_x=True, element_justification='right')],
    ]
    window = sg.Window("Prediction", layout, use_default_focus=False, finalize=True, modal=True)
    block_focus(window)
    event, values = window.read()
    window.close()
    return None

items = [
    "Automobile", "Chemical", "Engineering/Consulting", "FMCG",
    "Healthcare/Hospitality", "Infrastructue", "IT/Comm/DC", "Manufacturing",
    "Mines", "Energy/Oil & Gas", "Pharma", "Retail", "Cement",
]
length = len(items)
size = (max(map(len, items)), 1)

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

column_layout = []
line = []
num = 4
for i, item in enumerate(items):
    line.append(sg.Button(item, size=size, metadata=False))
    if i%num == num-1 or i==length-1:
        column_layout.append(line)
        line = []

layout = [
    [sg.Text('Choose the Industry')],
    [sg.Column(column_layout)],
]
window=sg.Window("Risk Predictor", layout, use_default_focus=False, finalize=True)
block_focus(window)

sg.theme("DarkGreen3")
while True:

    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break
    elif event in items:
        industry = event
        observation = popup_predict_risk(industry)
        if observation is not None:
            popup_prediction(industry, observation)

window.close()
