在PySimpleGUI中呈现HTML？

Question

有人知道是否有可能让PySimpleGUI呈现HTML吗？

我不是在追求一个成熟的浏览器，只是一个生活在PySimpleGUI窗口中的HTML浏览器。

我知道tkinter有一个叫做tk_html_widgets的模块，我也在研究webview模块能做什么。

我知道Qt是可能的，因为PySide附带了这样一个小部件，尽管我真的很喜欢PySimpleGUI。

我只是想知道是否有人会有这样的建议。

例如，我能否以某种方式将TK小部件(如tk_html_widgets )导入到PySimpleGUI中。

也许我遗漏了什么，而pysimpleGUI已经有了一个我不知道的HTML元素。

这里，仅供参考，库tkhtmlview用于HTML解析器和构建器。

当超时事件发生时，您可以调用set_html(advertise, html)来更新新的公告/html，当从internet加载某些内容时，它可能会保存在那里。

from tkhtmlview import html_parser
import PySimpleGUI as sg

def set_html(widget, html, strip=True):
    prev_state = widget.cget('state')
    widget.config(state=sg.tk.NORMAL)
    widget.delete('1.0', sg.tk.END)
    widget.tag_delete(widget.tag_names)
    html_parser.w_set_html(widget, html, strip=strip)
    widget.config(state=prev_state)

html = """
<td colspan="2" class="infobox-image"><a href="https://en.wikipedia.org/wiki/RoboCop" class="image">

"""

font = ("Courier New", 12, 'bold')
sg.theme("DarkBlue3")
sg.set_options(font=font)

layout_advertise = [
    [sg.Multiline(
        size=(25, 10),
        border_width=2,
        text_color='white',
        background_color='green',
        disabled=True,
        no_scrollbar=True,
        expand_x=True,
        expand_y=True,
        key='Advertise')],
]

keypad = [
    ["Rad/Deg",          "x!",   "(",  ")", "%", "AC"],
    ["Inv",       "sin", "ln",   "7", "8", "9", "÷" ],

]

layout_calculator = [
    [sg.Button(
        key,
        size=(7, 4),
        expand_x=key=="Rad/Deg",
        button_color=('white', '#405373') if key in "1234567890" else sg.theme_button_color(),
     ) for key in line]
            for line in keypad]

layout = [
    [sg.Frame("Calculator", layout_calculator, expand_x=True, expand_y=True),
     sg.Frame("Advertise",  layout_advertise, expand_x=True, expand_y=True)],
]
window = sg.Window('Title', layout, finalize=True, use_default_focus=False)
for element in window.key_dict.values():
    element.block_focus()

advertise = window['Advertise'].Widget

html_parser = html_parser.HTMLTextParser()
set_html(advertise, html)
width, height = advertise.winfo_width(), advertise.winfo_height()

while True:

    event, values = window.read()
    if event in (sg.WINDOW_CLOSED, 'Exit'):
        break
    print(event, values)

window.close()

看起来，您可以使用tkhtmlview小部件来完成这一任务。我认为关键是使用TKroot窗口的PySimpleGUI属性获取tk根节点的句柄。您应该能够使用该句柄绘制大多数tk小部件。下面是一个在PySimpleGUI窗口中绘制HTML标签的简单示例：

import PySimpleGUI as sg
from tkhtmlview import HTMLLabel

layout = [[]]

window = sg.Window('Canvas test', layout, finalize=True)

my_label = HTMLLabel(window.TKroot, html='<h1>foobar</h1>')

my_label.pack()

while True:
    event, values = window.read()
    if event == sg.WIN_CLOSED:
        break
