介绍:
在当今数字化的时代,我们经常需要管理和访问大量的网页链接和相关说明。为了更方便地管理这些链接,我们可以使用wxPython库创建一个简单而实用的Caption和URL管理器应用程序。本文将介绍如何使用wxPython和XML数据源创建一个具有按钮和Web视图的应用程序窗口,以便轻松管理和访问各种网页链接。

步骤:
import wx
import wx.html2
import xml.etree.ElementTree as ET
class MyFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, title="Caption and URL Manager", size=(800, 600))
# 窗口的初始化和布局代码
self.panel = wx.Panel(self)
self.sizer = wx.BoxSizer(wx.HORIZONTAL)
self.button_panel = wx.Panel(self.panel)
self.button_sizer = wx.BoxSizer(wx.VERTICAL)
self.scroll = wx.ScrolledWindow(self.button_panel)
self.scroll.SetScrollRate(0, 20)
self.web_panel = wx.Panel(self.panel)
self.web_sizer = wx.BoxSizer(wx.VERTICAL)
# 为按钮面板和Web视图面板创建布局和容器
def load_data(self):
try:
tree = ET.parse('data.xml')
root = tree.getroot()
for child in root:
caption = child.find('caption').text
url = child.find('url').text
button = wx.Button(self.scroll, label=caption)
button.SetMinSize(wx.Size(-1, 150))
icon = wx.Bitmap("./icons/hyperlink.png", wx.BITMAP_TYPE_PNG)
button.SetBitmap(icon)
button.Bind(wx.EVT_BUTTON, lambda event, u=url: self.on_button_click(event, u))
self.scroll_sizer.Add(button, proportion=1, flag=wx.EXPAND | wx.ALL, border=5)
# 将按钮添加到布局管理器中
def on_button_click(self, event, url):
self.web_view.LoadURL(url)
app = wx.App()
frame = MyFrame(None)
app.MainLoop()
全部代码:
import wx
import wx.html2
import xml.etree.ElementTree as ET
class MyFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, title="Caption and URL Manager", size=(800, 600))
self.panel = wx.Panel(self)
self.sizer = wx.BoxSizer(wx.HORIZONTAL)
self.button_panel = wx.Panel(self.panel)
self.button_sizer = wx.BoxSizer(wx.VERTICAL)
self.scroll = wx.ScrolledWindow(self.button_panel)
self.scroll.SetScrollRate(0, 20) # 设置滚动速率,垂直滚动每次滚动20个像素
self.scroll_sizer = wx.BoxSizer(wx.VERTICAL)
self.scroll.SetSizer(self.scroll_sizer)
self.web_panel = wx.Panel(self.panel)
self.web_sizer = wx.BoxSizer(wx.VERTICAL)
self.web_view = wx.html2.WebView.New(self.web_panel)
self.web_sizer.Add(self.web_view, proportion=1, flag=wx.EXPAND)
self.web_panel.SetSizer(self.web_sizer)
self.load_data()
self.panel.SetSizer(self.sizer)
self.sizer.Add(self.button_panel, proportion=1, flag=wx.EXPAND)
self.sizer.Add(self.web_panel, proportion=2, flag=wx.EXPAND)
self.panel.Layout()
self.Show()
def load_data(self):
try:
tree = ET.parse('data.xml')
root = tree.getroot()
for child in root:
caption = child.find('caption').text
url = child.find('url').text
# button = wx.Button(self.scroll, label=caption)
button = wx.Button(self.scroll, label=caption)
button.SetMinSize(wx.Size(-1, 150)) # 设置按钮最小尺寸为高度为200像素
icon = wx.Bitmap("./icons/hyperlink.png", wx.BITMAP_TYPE_PNG) # 从文件加载图标
button.SetBitmap(icon)
button.Bind(wx.EVT_BUTTON, lambda event, u=url: self.on_button_click(event, u))
self.scroll_sizer.Add(button, proportion=1, flag=wx.EXPAND | wx.ALL, border=5)
self.scroll.SetSizer(self.scroll_sizer)
self.scroll_sizer.Fit(self.scroll) # 调整尺寸以适应内容
self.button_sizer.Add(self.scroll, proportion=1, flag=wx.EXPAND)
self.button_panel.SetSizer(self.button_sizer)
except FileNotFoundError:
pass
def on_button_click(self, event, url):
self.web_view.LoadURL(url)
app = wx.App()
frame = MyFrame(None)
app.MainLoop()
总结:
通过本文,我们学习了如何使用wxPython库创建一个Caption和URL管理器应用程序。通过解析XML数据源并创建按钮,我们可以轻松地管理和访问各种网页链接。使用wxPython的优势在于它提供了丰富的界面控件和强大的布局管理器,使我们能够快速构建功能强大的桌面应用程序。希望本文对您入门wxPython应用程序开发有所帮助,祝您编程愉快!
