wx.BitmapButton

位图按钮是显示一幅位图的按钮. 它有另外三种形态. 选中的、聚焦的 (focused) 以及显示出的. 这些形态都可以设置对应不同的位图.[more…]

媒体播放器是应用位图按钮的好例子. 我们在媒体播放器中会看到播放、暂停、下一个、前一个以及音量等位图按钮. 因此，下面将创建一个媒体播放器的骨架作为示例.

#!/usr/bin/python#coding=utf-8#player.pyimport wxclass MyFrame(wx.Frame):    def __init__(self, parent, id, title):        wx.Frame.__init__(self, parent, id, title, size=(350, 300))        panel = wx.Panel(self, -1)                pnl1 = wx.Panel(self, -1)        pnl1.SetBackgroundColour(wx.BLACK)        pnl2 = wx.Panel(self, -1)        menubar = wx.MenuBar()        file = wx.Menu()        play = wx.Menu()        view = wx.Menu()        tools = wx.Menu()        favorites = wx.Menu()        help = wx.Menu()                file.Append(101, '&Quit', '退出程序')                menubar.Append(file, '&File')        menubar.Append(play, '&Play')        menubar.Append(view, '&View')        menubar.Append(tools, '&Tools')        menubar.Append(favorites, 'F&avorites')        menubar.Append(help, '&Help')                slider1 = wx.Slider(pnl2, -1, 0, 0, 1000)        pause = wx.BitmapButton(pnl2, -1, wx.Bitmap('./icons/stock_media-pause.png'))        play = wx.BitmapButton(pnl2, -1, wx.Bitmap('./icons/stock_media-play.png'))        next = wx.BitmapButton(pnl2, -1, wx.Bitmap('./icons/stock_media-next.png'))        prev = wx.BitmapButton(pnl2, -1, wx.Bitmap('./icons/stock_media-prev.png'))        volume = wx.BitmapButton(pnl2, -1, wx.Bitmap('./icons/volume.png'))        slider2 = wx.Slider(pnl2, -1, 0, 0, 100, size=(120, -1))                vbox = wx.BoxSizer(wx.VERTICAL)        hbox1 = wx.BoxSizer(wx.HORIZONTAL)        hbox2 = wx.BoxSizer(wx.HORIZONTAL)                hbox1.Add(slider1, 1)        hbox2.Add(pause)        hbox2.Add(play, flag=wx.RIGHT, border=5)        hbox2.Add(next, flag=wx.LEFT, border=5)        hbox2.Add(prev)        hbox2.Add((150, -1), 1, flag=wx.EXPAND | wx.ALIGN_RIGHT)        hbox2.Add(volume, flag=wx.ALIGN_RIGHT)        hbox2.Add(slider2, flag=wx.ALIGN_RIGHT | wx.TOP | wx.LEFT, border=5)        vbox.Add(hbox1, 1, wx.EXPAND | wx.BOTTOM, 10)        vbox.Add(hbox2, 1, wx.EXPAND)        pnl2.SetSizer(vbox)                sizer = wx.BoxSizer(wx.VERTICAL)        sizer.Add(pnl1, 1, flag=wx.EXPAND)        sizer.Add(pnl2, flag=wx.EXPAND | wx.BOTTOM | wx.TOP, border=10)                self.SetMinSize((350, 300))        self.SetMenuBar(menubar)        self.CreateStatusBar()        self.SetSizer(sizer)        self.Center()        class MyApp(wx.App):    def OnInit(self):        frame = MyFrame(None, -1, 'Player')        frame.Show(True)        self.SetTopWindow(frame)        return True    app = MyApp(0)app.MainLoop()
