python中pywebview框架使用方法记录_Python

前言

pywebview是python的一个库，类似于flask框架，这也是用来构建网页的软件包，它的特点就是不用更多的和html语言和js语言，更多的使用python语言就可以完成网页的创建和元素的监听该库的简介和示例，简单使用看示例足够，但是其中也不够详尽：https://pywebview.flowrl.com/

一、安装pywebview

首先，确保已经安装了pywebview，可以通过以下命令进行安装：

pip install pywebview

二、简单使用

简单的创建界面和一些基础操作，这里不再赘述，也没什么营养，官方示例都已给出，这里只贴上一些示例：

一个示例界面;

import webview

if __name__ == '__main__':
    # create a standard webview window
    window = webview.create_window('simple browser', 'https://pywebview.flowrl.com/hello')
    webview.start()

一个自制界面：

import webview

html = """
  <html>
    <head></head>
    <body>
      <h2>links</h2>

      <p><a href='https://pywebview.flowrl.com'>regular links</a> are opened in the application window.</p>
      <p><a href='https://pywebview.flowrl.com' target='_blank'>target='_blank' links</a> are opened in an external browser.</p>

    </body>
  </html>
"""

if __name__ == '__main__':
    window = webview.create_window('link types', html=html)
    webview.start()

调用的是外部界面：

import webview

if __name__ == '__main__':
    window = webview.create_window(title='webview app', url="https://hailuoai.com/?type=chat&chatid=251739240281759747/", confirm_close=true,
                                   zoomable=true, vibrancy=true, width=1275, height=745)
    webview.start(user_agent='mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/125.0.0.0 safari/537.36 edg/125.0.0.0',
                  debug=true)

于是可以从这几个例子看出来，pywebview主要有两种，可以是自制的网页html参数，又或者是url的外部链接。

三、高级使用

主要是关于dom的元素创建选择何使用：按钮等等，关于bind函数

import random
import webview

rectangles = []

def random_color():
    red = random.randint(0, 255)
    green = random.randint(0, 255)
    blue = random.randint(0, 255)

    return f'rgb({red}, {green}, {blue})'

def bind(window):
    def toggle_disabled():
        disabled = none if len(rectangles) > 0 else true
        remove_button.attributes = { 'disabled': disabled }
        empty_button.attributes = { 'disabled': disabled }
        move_button.attributes = { 'disabled': disabled }

    def create_rectangle(_):
        color = random_color()
        rectangle = window.dom.create_element(f'<div class="rectangle" style="background-color: {color};"></div>', rectangle_container)
        rectangles.append(rectangle)
        toggle_disabled()

    def remove_rectangle(_):
        if len(rectangles) > 0:
            rectangles.pop().remove()
        toggle_disabled()

    def move_rectangle(_):
        if len(rectangle_container.children) > 0:
            rectangle_container.children[-1].move(circle_container)

    def empty_container(_):
        rectangle_container.empty()
        rectangles.clear()
        toggle_disabled()

    def change_color(_):
        circle.style['background-color'] = random_color()

    def toggle_class(_):
        circle.classes.toggle('circle')

    rectangle_container = window.dom.get_element('#rectangles')
    circle_container = window.dom.get_element('#circles')
    circle = window.dom.get_element('#circle')

    toggle_button = window.dom.get_element('#toggle-button')
    toggle_class_button = window.dom.get_element('#toggle-class-button')
    duplicate_button = window.dom.get_element('#duplicate-button')
    remove_button = window.dom.get_element('#remove-button')
    move_button = window.dom.get_element('#move-button')
    empty_button = window.dom.get_element('#empty-button')
    add_button = window.dom.get_element('#add-button')
    color_button = window.dom.get_element('#color-button')

    toggle_button.events.click += lambda e: circle.toggle()
    duplicate_button.events.click += lambda e: circle.copy()
    toggle_class_button.events.click += toggle_class
    remove_button.events.click += remove_rectangle
    move_button.events.click += move_rectangle
    empty_button.events.click += empty_container
    add_button.events.click += create_rectangle
    color_button.events.click += change_color

if __name__ == '__main__':
    window = webview.create_window(
        'dom manipulations example', html='''
            <html>
                <head>
                <style>
                    button {
                        font-size: 100%;
                        padding: 0.5rem;
                        margin: 0.3rem;
                        text-transform: uppercase;
                    }

                    .rectangle {
                        width: 100px;
                        height: 100px;
                        display: flex;
                        justify-content: center;
                        align-items: center;
                        margin: 0.5rem;
                        border-radius: 5px;
                        background-color: red;
                    }

                    .circle {
                        border-radius: 50px;
                        background-color: red;
                    }

                    .circle:hover {
                        background-color: green;
                    }

                    .container {
                        display: flex;
                        flex-wrap: wrap;
                    }
                </style>
                </head>
                <body>
                    <button id="toggle-button">toggle circle</button>
                    <button id="toggle-class-button">toggle class</button>
                    <button id="color-button">change color</button>
                    <button id="duplicate-button">duplicate circle</button>
                    <button id="add-button">add rectangle</button>
                    <button id="remove-button" disabled>remove rectangle</button>
                    <button id="move-button" disabled>move rectangle</button>
                    <button id="empty-button" disabled>remove all</button>
                    <div id="circles" style="display: flex; flex-wrap: wrap;">
                        <div id="circle" class="rectangle circle"></div>
                    </div>

                    <div id="rectangles" class="container"></div>
                </body>
            </html>
        '''
    )
    webview.start(bind, window)

并且使用event可以监听按钮等等的事件发生

并且是支持动态生成元素的：

with open(file_path, 'r', encoding='utf-8') as file:
    for line in file:
        count += 1
        window.dom.create_element(
            f"<input id='word{count}' writingsuggestions='true' type='text' class='editable-textbox'>111</input>"
        )
        temp = window.dom.get_element(f'#word{count}')
        line = line.rstrip('\n')
        temp.value = line
