我不能使用wx.ProgressDialog,因爲我需要在對話框中添加額外的內容(暫停按鈕以及有關當前正在處理內容的信息)。是否有可以在我自己的對話框中使用的進度條控件?wxPython進度條

我當然可以自己畫一些簡單的東西,但由於該程序需要在Mac OS X,Windows和Linux上運行,如果進度條具有本機外觀,它會更好。

你總是可以創建自己的wx.Dialog的衍生物和使用分級機,在您需要的小工具加入。

這裏有一個從我的程序,例如:

class ProgressDialog(wx.Dialog): 
    """ 
    Shows a Progres Gauge while an operation is taking place. May be cancellable 
    which is possible when converting pdf/ps 
    """ 
    def __init__(self, gui, title, to_add=1, cancellable=False): 
     """Defines a gauge and a timer which updates the gauge.""" 
     wx.Dialog.__init__(self, gui, title=title, 
          style=wx.CAPTION) 
     self.gui = gui 
     self.count = 0 
     self.to_add = to_add 
     self.timer = wx.Timer(self) 
     self.gauge = wx.Gauge(self, range=100, size=(180, 30)) 
     sizer = wx.BoxSizer(wx.VERTICAL) 
     sizer.Add(self.gauge, 0, wx.ALL, 10) 

     if cancellable: 
      cancel = wx.Button(self, wx.ID_CANCEL, _("&Cancel")) 
      cancel.SetDefault() 
      cancel.Bind(wx.EVT_BUTTON, self.on_cancel) 
      btnSizer = wx.StdDialogButtonSizer() 
      btnSizer.AddButton(cancel) 
      btnSizer.Realize() 
      sizer.Add(btnSizer, 0, wx.ALIGN_CENTER | wx.TOP | wx.BOTTOM, 10) 

     self.SetSizer(sizer) 
     sizer.Fit(self) 
     self.SetFocus() 

     self.Bind(wx.EVT_TIMER, self.on_timer, self.timer) 
     self.timer.Start(30) 


    def on_timer(self, event): 
     """Increases the gauge's progress.""" 
     self.count += self.to_add 
     self.gauge.SetValue(self.count) 
     if self.count > 100: 
      self.count = 0 


    def on_cancel(self, event): 
     """Cancels the conversion process""" 
     # do whatever
