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<code>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>code>
<p><a href='https://pywebview.flowrl.com' target='_blank'>target='_blank' links</a> are opened in an external browser.</p>code>
</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,code>
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',code>
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)code>
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='''code>
<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>code>
<button id="toggle-class-button">Toggle class</button>code>
<button id="color-button">Change color</button>code>
<button id="duplicate-button">Duplicate circle</button>code>
<button id="add-button">Add rectangle</button>code>
<button id="remove-button" disabled>Remove rectangle</button>code>
<button id="move-button" disabled>Move rectangle</button>code>
<button id="empty-button" disabled>Remove all</button>code>
<div id="circles" style="display: flex; flex-wrap: wrap;">code>
<div id="circle" class="rectangle circle"></div>code>
</div>
<div id="rectangles" class="container"></div>code>
</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:code>
for line in file:
count += 1
window.dom.create_element(
f"<input id='word{count}' writingsuggestions='true' type='text' class='editable-textbox'>111</input>"code>
)
temp = window.dom.get_element(f'#word{count}')
line = line.rstrip('\n')
temp.value = line
希望可以帮助到大家！！
