如何在wxpython的状态栏中放置进度条

Question

以下代码将进度条放置在状态栏的第一个字段:

self.statusbar = self.CreateStatusBar()
self.statusbar.SetFieldsCount(3)
self.statusbar.SetStatusWidths([320, -1, -2])
self.progress_bar = wx.Gauge(self.statusbar, -1, style=wx.GA_HORIZONTAL|wx.GA_SMOOTH)

如何在字段号中放置进度条。2的状态栏?

Answer 1

状态栏有一个很好的自定义扩展，叫做EnhancedStatusBar，你可以在这里找到:http://xoomer.virgilio.it/infinity77/main/EnhancedStatusBar.html

它允许你添加几乎任何小部件到状态栏。下面是使用这个小部件向状态栏的第二个字段添加进度条的示例:

import EnhancedStatusBar
import wx
########################################################################
class MyPanel(wx.Panel):
    """"""
    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)

########################################################################
class MyFrame(wx.Frame):
    """"""
    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Enhanced Statusbar Demo")
        panel = MyPanel(self)

        self.statusbar = EnhancedStatusBar.EnhancedStatusBar(self)
        self.statusbar.SetSize((-1, 23))
        self.statusbar.SetFieldsCount(2)
        self.SetStatusBar(self.statusbar)
        self.progress = wx.Gauge(self.statusbar, range=20)
        self.statusbar.AddWidget(self.progress, pos=1)
        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER, self.updateGauge)
        self.timer.Start(100)
    #----------------------------------------------------------------------
    def updateGauge(self, event):
        """"""
        self.progress.Pulse()
#----------------------------------------------------------------------
if __name__ == "__main__":
    app = wx.App(False)
    frame = MyFrame()
    frame.Show()
    app.MainLoop()

在Windows 7上测试Python 2.6/wxPython 2.8和Python 2.7/wxPython 2.9。然而，它似乎不能与wxPython 3一起工作。
