wxPython进度条

我无法使用wx.ProgressDialog,因为我需要在对话框中添加额外的内容(暂停按钮和有关当前正在处理的内容的信息)。是否只有我可以在自己的对话框中使用的进度条控件?

我当然可以自己画一些简单的东西,但由于程序需要在Mac OS X,Windows和Linux上运行,所以如果进度条具有原生外观会更好。

您可以随时创建自己的wx.Dialog衍生产品并使用sizer,添加您需要的小部件。

这是我的计划中的一个,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
