wxpython 怎么设置背景图

Question

网上查来查去都是那一两个代码互相复制，有没有最新的实现方案。

Answer 1

只要你背景图片和你软件界面大小一致就行了

import wx
class MyFrame(wx.Frame):
    def OnEraseBack(self, event):
        dc = event.GetDC()
        if not dc:
            dc = wx.ClientDC(self)
            rect = self.GetUpdateRegion().GetBox()
            dc.SetClippingRect(rect)
        dc.Clear()
        bmp = wx.Bitmap("background.jpg")
        dc.DrawBitmap(bmp, 0, 0)

    def __init__(self, parent, title):
        super(MyFrame, self).__init__(parent, title=title, size=(600, 450))
        panel = wx.Panel(self)
        panel.Bind(wx.EVT_ERASE_BACKGROUND, self.OnEraseBack)
        # 垂直盒子
        vbox = wx.BoxSizer(wx.VERTICAL)
        # 水平盒子
        nmbox = wx.BoxSizer(wx.HORIZONTAL)
        # 创建静态文本
        hero_label = wx.StaticText(panel, -1, label='cs:')
        # 创建字体
        font = wx.Font(10, wx.MODERN, wx.NORMAL, wx.NORMAL, False, 'Consolas')
        hero_label.SetFont(font)
        # self.save_label = wx.StaticText(panel, -1, label='保存路径：')
        # 创建一个下拉列表
        self.hero_list = ['全部']
        self.heros = wx.ComboBox(panel, choices=self.hero_list,
                                 style=wx.CB_READONLY, value=self.hero_list[0],
                                 size=(150, -1))
        # 创建一个下载按钮
        self.download_button = wx.Button(panel, label='下载', size=(100, -1))
        # 将上面创建的控件添加到水平盒子里
        nmbox.Add(hero_label, 0, wx.ALL | wx.EXPAND, 14)
        nmbox.Add(self.heros, 0, wx.ALL | wx.EXPAND, 10)
        nmbox.AddSpacer(20)
        nmbox.Add(self.download_button, 0, wx.ALIGN_CENTER_VERTICAL | wx.ALIGN_CENTER_HORIZONTAL, 5)
        vbox.Add(nmbox, 0, wx.ALL | wx.CENTER, 5)
        result_label = wx.StaticText(panel, -1, "下载结果：")
        result_label.SetFont(font)
        vbox.Add(result_label, 0, wx.ALL | wx.EXPAND, 5)
        # 创建文本域
        self.download_logs = wx.TextCtrl(panel, -1, size=(200, 200), style=wx.TE_MULTILINE)
        self.download_logs.SetInsertionPoint(0)
        #  在垂直盒子里添加文本域
        vbox.Add(self.download_logs, 1, wx.ALL | wx.EXPAND, 5)
        # 激活sizers
        panel.SetSizer(vbox)
        self.Show(True)
if __name__ == '__main__':
    app = wx.App(False)
    frame = MyFrame(None, '测试')
    frame.Show()
    app.MainLoop()
