python之PySimpleGUI（三）dome

dome1第一个程序
其实会了第一个程序后面基本就都通了，就这么简单，后面只需要注意一下细节就可以
import PySimpleGUI as sg

sg.theme('Dark Blue 3')  # please make your creations colorful

# All the stuff inside your window. This is the PSG magic code compactor...这个也就是布局，线性布局，挺简单
layout = [  [sg.Text('Some text on Row 1')],
            [sg.Text('Enter something on Row 2'), sg.InputText()],
            [sg.OK(), sg.Cancel()]]

# Create the Window
window = sg.Window('Window Title', layout)实例化，窗口不会出现
# Event Loop to process "events"
while True:             循环
    event, values = window.read()获取事件结果是个字典
    if event in (sg.WIN_CLOSED, 'Cancel'):
        break
window['key'].update('压我改变的值')通过键来修改值
window.close() 窗口关闭


2  dome2   2个窗口，并且都是活动的
# Design pattern 2 - First window remains active

layout = [[ sg.Text('Window 1'),],
          [sg.Input(do_not_clear=True)],
          [sg.Text(size=(15,1), key='-OUTPUT-')],
          [sg.Button('Launch 2'), sg.Button('Exit')]]

win1 = sg.Window('Window 1', layout)

win2_active = False
while True:
    ev1, vals1 = win1.read(timeout=100)
    win1['-OUTPUT-'].update(vals1[0])
    if ev1 == sg.WIN_CLOSED or ev1 == 'Exit':
        break

    if not win2_active and ev1 == 'Launch 2':
         win2_active = True
         #win1.Hide()窗口1隐藏
         layout2 = [[sg.Text('Window 2')],
                   [sg.Button('Exit')]]

         win2 = sg.Window('Window 2', layout2)

    if win2_active:
        ev2, vals2 = win2.read(timeout=100)
        if ev2 == sg.WIN_CLOSED or ev2 == 'Exit':
            win2_active  = False
            win2.close()
            #win1.UnHide()窗口1出现

this one long import has the effect of making the code more compact as there is no 'sg.' prefix required for Elements

"""
Demo Columns and Frames
Demonstrates using mixture of Column and Frame elements to create a nice window layout.
A couple of the concepts shown here include:
* Using Columns and Frames with specific sizes on them
* Importing all required classes so that "sg." is not required on any objects. This makes the code more compact and readable

There are 3 columns. Two are side by side at the top and the third is along the bottom
