直接从列表框和通过搜索框选择的列需要保存

Question

在 PySimpleGUI 屏幕以及其他元素中，我有一个输入文本（搜索框）和列值列表框。我尝试为列表框添加搜索功能时遇到问题。 我刚刚开始尝试使用 PySimpleGUI，任何帮助都会很棒:-)

预期输出： 应该能够通过列表框上的搜索框提取选定的值，并从列表框中选择这些值

下面是我尝试过的代码：

form = sg.FlexForm('File split script')

layout = [
            [sg.Text('Please upload file & enter the remaining details and click "submit" button to execute the script')],
            [sg.Text('Input File', size=(10, 1), auto_size_text=False, justification='left')],
            [sg.InputText('Please upload either the CSV/XLSX input file'), sg.FileBrowse(key="-Input_Values-")],
            [sg.Text('Output File', size=(10, 1), auto_size_text=False, justification='left')],
            [sg.InputText('Please choose the output folder'), sg.FolderBrowse(key="-Output_Values-")],
            [sg.Text('No of records per file'), sg.InputText(key = '-no_of_records-'), sg.Text('in multiples of 1000')],
            [sg.Text(' ',size=(5, 1))],
            [sg.InputText('',key = '-Search_Box-', enable_events=True),sg.Button('Merge_Search_Fields_And_Listbox_Selected_Fields')],
            [sg.Text('Select the Required columns')],
            [sg.Listbox(values = (),select_mode= 'multiple', size=(30, 30), key='-ListBox-', enable_events=True),  sg.Button("Populate Columns"), sg.Text('Double click the button',font=('Arial', 13, 'bold')) ],
            [sg.Submit(), sg.Cancel()]
         ]

window = form.Layout(layout)
event, values = window.read()

while True:
    event, values = window.read()
    print(event, values)
    file_path = values[0]

    if event == sg.WIN_CLOSED or event == 'Cancel':
        break

    if event == 'Submit':
        break

    if event == 'Populate Columns':
        #extracts columns from selected input file - stores in 
        #column_names list and populates in ListBox

        column_names = list(df_full_content.columns)
        window.Element('-ListBox-').update(values= column_names)

    # My issue is with handling search box functionality
    if event == '-Search_Box-':
        text = values['-Search_Box-']
        if text in column_names:
            search_set.add(text)

        window.Element('-ListBox-').update(values=search_set)

Answer 1

在这里选择列

• 模式1的两种方法：单击列表框中的项目
• 模式2：输入列中输入元素中的输入元素，带有输入键，

您不能在模式1中使用，然后在模式2中使用，然后使用模式1以进行以下代码。
要从模式2返回模式1，您可以单击reset按钮。

当然，您可以通过编程代码为其设置任何规则，但不能遵循它的代码，而不是本期的问题。

import PySimpleGUI as sg

items = [f'Item {i}' for i in range(10)]

search = set()
layout = [
    [sg.Text('Sepcified Column')],
    [sg.Input(size=10, key='SEARCH')],
    [sg.Listbox(items, size=(8, 5), select_mode=sg.LISTBOX_SELECT_MODE_MULTIPLE, key='LISTBOX')],
    [sg.Button('Submit'), sg.Button('Reset'), sg.Button('Exit')],
]
window = sg.Window('Title', layout, finalize=True)
window['SEARCH'].bind("<Return>", "+RETURN")
while True:

    event, values = window.read()

    if event in (sg.WIN_CLOSED, 'Exit'):
        break
    print(event, values)
    if event == 'SEARCH+RETURN':
        item  = values['SEARCH']
        print(item)
        if item in items:
            search.add(item)
            data = sorted(list(search))
            index = data.index(item)
            window['LISTBOX'].update(values=data, set_to_index=[i for i in range(len(data))], scroll_to_index=index)
            window['SEARCH'].update('')

    elif event == 'Reset':
        search = set()
        window['LISTBOX'].update(values=items)

    elif event == 'Submit':
        selected = values['LISTBOX']
        print(selected)

window.close()

['Item 1', 'Item 2', 'Item 3']
