PySimpleGUI --Python图形化界面库

注：4.60.5版本及之前都是免费的，现在5.0.0版本之后开始收费了。

太贵了跑路了

安装：

<code>pip install PySimpleGUI

1 布局模板

1.1 常用布局

import PySimpleGUI as sg

layout = [

[],

[],

[],

[],

[],

]

#每个[]是一行

window = sg.Window('',layout)

while True:

event,values = window.read()

if event == None:

break

window.close()

1.2 加号布局

<code>import PySimpleGUI as sg

layout = [

[sg.Text('请输入基本信息')],

[[sg.Text('姓名')]+[sg.In()]]+[

[sg.Text('性别')]+[sg.In()]]+[

[sg.Text('国籍')]+[sg.In()]]+[

[sg.B('确认')]+[sg.B('取消')]]

]

window = sg.Window('Python布局2',layout)

while True:

event, values =window.read()

if event == sg.WIN_CLOSED:

break

if event == '确认':

break

window.close()

1.3 循环布局

import PySimpleGUI as sg

layout = [

[[sg.In(i)] for i in ['姓名','性别','国籍']]

]

window = sg.Window('Python',layout)

while True:

event, values =window.read()

if event == sg.WIN_CLOSED:

break

window.close()

2 菜单

2.1 菜单栏

menu_def = [['&File', ['&New', '&Open', '!Save', 'E&xit', ]],

['&Edit', ['C&ut', '&Copy::CP', '&Paste', '&Undo'], ],

['&Help', '&About...'], ]

2.2 右键菜单

<code>rightclick=['&Edit', ['C&ut', '&Copy','&Paste', '&Undo']]

menu_def = [

['&File', ['&New', '&Open', '&Save', 'E&xit',]], rightclick,

['&Help', '&About...'],

]

#将其用作 Window 构造函数中 right_click_menu 参数的值

window=psg.Window("Menu", layout, size=(715, 300), right_click_menu=rightclick)

3 弹出窗口

3.1 基本弹窗

• popup_ok − 仅显示带有 OK 按钮的 Popup
• popup_ok_cancel − 显示带有 OK 和 Cancel 按钮的弹出窗口
• popup_cancel − 显示带有"cancelled"已取消按钮文本的弹出窗口
• popup_yes_no − 显示带有 Yes 和 No 按钮的弹出窗口
• popup_error − 带有彩色按钮和"Error"错误作为按钮文本的弹出窗口

这些函数返回用户按下的按钮的文本。 例如，如果用户按下 ok-cancel 弹出窗口的 OK 按钮，它会返回 Ok，这可以在进一步的编程逻辑中使用。

以下弹出窗口接受用户以文本形式输入或让用户从选择器中选择文件/文件夹/日期。

• popup_get_text − 显示带有文本输入字段的弹出窗口。 返回输入的文本，如果关闭/取消则返回 None

• popup_get_file − 显示带有文本输入字段和浏览按钮的弹出窗口，以便用户可以选择文件。

• popup_get_folder − 显示带有文本输入字段和浏览按钮的弹出窗口，以便可以选择文件夹。

• popup_get_date − 显示一个日历窗口，获取用户的选择，以元组形式返回(mon, day, year)

• popup_scrolled − 滚动弹窗

  import PySimpleGUI as sg

  pwd = '123'

  list = ['资料1','资料2','资料3','资料4']

  while True:

  result = sg.PopupGetText('密码输入框')

  if pwd ==result :

  break

  elif result ==None:

  exit()

  else:sg.popup('密码错误')

  layoutb=[[sg.LB(list,size=(30,5))]]

  layout=[[sg.Frame('资料库',layoutb)]]

  window=sg.Window('演示',layout)

  while True:

  event, values = window.read()

  if event == None:

  break

  window.close()

  """

  sg.PopupGetFile()#文件选择弹窗

  sg.PopupGetFolder()#文件夹选择

  sg.PopupAnnoying()#没有标题栏可随意移动

  sg.PopupAutoClose()#显示一段时间自动关闭

  sg.PopupCancel()

  sg.PopupOKCancel()

  sg.PopupOK()

  sg.PopupError()

  sg.PopupNoButtons()

  """

  运行截图：

点击OK

4 元素类

4.1 元素类方法

5 主题

<code>import PySimpleGUI as sg

print(sg.theme_list())

sg.theme('DarkRed')

sg.Popup('弹窗演示')

# print(sg.theme_button_color())

sg.theme_button_color(('black', '#ad1d45'))

sg.Popup('演示弹窗','按键字体变黑色')

6 将程序打包成exe

安装pysimplegui-exemaker：

pip install pysimplegui-exemaker

运行：

python -m pysimplegui-exemaker.pysimplegui-exemaker
