PySimpleGUI 的基本使用

# PySimpleGUI:
# 在PySimpleGUI中，小部件（widgets）被称为element,element的名称与编码中使用的名称保持一致。
# PySimpleGUI中有两种类型的窗口：1） one-shot window  2) persistent window(multiple reads using an event loop)


# 一、两种窗口模式：
# 1--one-shot window:

# 特点：read and then closes
# 语法：sg.Window("window Title",layout)  其中 layout 为三个一维数组构成的二维数组
# layout=[[sg.Text("my one-shot window")],[sg.InputText()],[sg.Submit(),sg.Cancel()]]

# 例 1：
from pathlib import Path
import PySimpleGUI as sg

layout=[[sg.Text("my one-shot window")],[sg.InputText()],[sg.Submit(),sg.Cancel()]]
Window=sg.Window("Window Title",layout)

event,values=Window.Read()   # event的值为 所点击的 button的名称，values为字典，字典的值为输入的内容
Window.Close()  # 不可少

print(event)      # "submit" or "cancel"
print(values)     # {0: 'hello world!'}
print(values[0])  # 'hello world!'


# 2--Persistent window (multiple reads using an event loop)  

# 特点：该模式实现多次读取
# 语法：

# 例 1：
from pathlib import Path
import PySimpleGUI as sg

# layout=[[sg.Text("my persistent window")],[sg.InputText(do_not_clear=True)],[sg.Submit(),sg.Exit()]]  
# layout=[[sg.Text("my persistent window")],[sg.InputText(do_not_clear=True)],[sg.Button("Submit"),sg.Exit()]]  
layout=[[sg.Text("my persistent window")],[sg.InputText(do_not_clear=True)],[sg.Button("Read"),sg.Exit()]]  
# do_not_clear默认为 True

while True:
    event,values=Window.Read()   # event的值为 所点击的 button的名称，values为字典，字典的值为输入的内容
    if event is None or event == "Exit":
        break
    print(event,values)

Window.Close()  # 不可少


# 例 2：
from pathlib import Path
import PySimpleGUI as sg

layout=[[sg.Text("my persistent window")],[sg.InputText(do_not_clear=False)],[sg.Submit(),sg.Exit()]]
Window=sg.Window("Window Title",layout)

while True:
    event,values=Window.Read()   # event的值为 所点击的 button的名称，values为字典，字典的值为输入的内容
    if event is None or event == "Exit":
        break
    print(event,values)

Window.Close()  # 不可少



# 二、应用：

# 1--创建数据表：
# layout里有多个 sg.Text()

from pathlib import Path
import PySimpleGUI as sg

layout=[
    [sg.Text("Please enter Name,Address,Phone")],
    [sg.Text("Name",size=(15,1)),sg.InputText()],   # key为 0
    [sg.Text("Address",size=(15,1)),sg.InputText("辽宁省黄泥川",key="address")],  # 可以有默认值，可以指定 key
    [sg.Text("Phone",size=(15,1)),sg.InputText()],  # 因为 address指定了 key,phone的 key就变为 1了。
    [sg.Submit(),sg.Cancel()]]

Window=sg.Window('Simple data entry window',layout)
event,values=Window.Read()
Window.Close()
print(event,values[0],values["address"],values[1])  # Submit Collin 辽宁省黄泥川 17763230890
    



# 2--文件浏览器：
# 例1：
from pathlib import Path
import PySimpleGUI as sg

layout = [[sg.Text('请选择一个文件')],
          [sg.InputText(), sg.FileBrowse()],
          [sg.Submit(), sg.Cancel()]]

# with sg.Window('SHA-1 & 256 Hash', layout) as window:
#     (event, (source_filename,)) = window.Read()

# print(event, source_filename)

Window=sg.Window('文件浏览器',layout)
event,value = Window.Read()
Window.Close()
    
print(value[0])  # C:/Users/XuYunPeng/Desktop/工具/Collin_test/log/20200721140356.log


# 例2：
layout = [[sg.Text('Enter 2 files to comare')],
          [sg.Text('File 1', size=(8, 1)), sg.InputText(), sg.FileBrowse()],
          [sg.Text('File 2', size=(8, 1)), sg.InputText(), sg.FileBrowse()],
          [sg.Submit(), sg.Cancel()]]

window = sg.Window('File Compare', layout)

event, values = window.Read()
window.Close()
print(event, values)

# 例3：
import PySimpleGUI as sg
import sys

layout = [[sg.Text('Document to open')],[sg.In(), sg.FileBrowse()], [sg.CloseButton('Open'), sg.CloseButton('Cancel')]]
if len(sys.argv) == 1:
    Window=sg.Window('My Script',layout)
    event, (fname,) = Window.Read()
    Window.Close()
else:
    fname = sys.argv[1]

if not fname:
    sg.Popup("Cancel", "No filename supplied")
    raise SystemExit("Cancelling: no filename supplied")
print(event, fname)



# 3--创建可复选的表单

import PySimpleGUI as sg

# def window_op(title, layout):
#     with sg.Window(title, layout) as window:
#         event, values = window.Read()
#     return event, values

def window_op(title, layout):
    window=sg.Window(title, layout)
    event, values = window.Read()
    window.Close()
    return event, values

layout = [[sg.Text('你喜欢的故事书是：')],
          [sg.Text('故事书：'), sg.Checkbox('哈利波特', sg.OK()), sg.Checkbox('三体'), sg.OK()]]

window_op("test",layout)  # ('OK', {0: True, 1: True})


# 4--pop 弹窗 （可以用来替代 print）
import PySimpleGUI as sg
v="坏蛋们"
sg.Popup('标题：',
         '你们已经被包围了，"{}"'.format(v),
         '快投降吧', "哈哈")


# 5--其他窗口元素：Listbox,Multiline,Menu,InputOptionMenu,Slider,InputText,Text,Frame,column等

import PySimpleGUI as sg

sg.ChangeLookAndFeel('GreenTan')  # 绿色的配色方案

# ------ Menu Definition ------ #
menu_def = [['File', ['Open', 'Save', 'Exit', 'Properties']],

                    initial_value='Spin Box 1')],
           [sg.Spin(values=('Spin Box 1', '2', '3'),

     sg.Slider(range=(1, 100), orientation='h', size=(34, 20), default_value=85)],
    [sg.InputOptionMenu(('Menu Option 1', 'Menu Option 2', 'Menu Option 3'))],
    [sg.Listbox(values=('Listbox 1', 'Listbox 2', 'Listbox 3'), size=(30, 3)),
     sg.Frame('Labelled Group', [[
         sg.Slider(range=(1, 100), orientation='v',
                   size=(5, 20), default_value=25),
         sg.Slider(range=(1, 100), orientation='v',
                   size=(5, 20), default_value=75),
         sg.Slider(range=(1, 100), orientation='v',
                   size=(5, 20), default_value=10),

    [sg.Text('_' * 80)],
    [sg.Text('Choose A Folder', size=(35, 1))],
    [sg.Text('Your Folder', size=(15, 1), auto_size_text=False, justification='right'),
     sg.InputText('Default Folder'), sg.FolderBrowse()],
    [sg.Submit(tooltip='Click to submit this window'), sg.Cancel()]
]


window = sg.Window('Everything bagel', layout,
                   default_element_size=(40, 1), grab_anywhere=False)

event, values = window.Read()
window.Close()
sg.Popup('Title',
         'The results of the window.',
         'The button clicked was "{}"'.format(event),
         'The values are', values)
