wxPython – wx.StatusBar 中的 PopStatusText()函数

在本文中,我们将学习与 wxPython 的 wx.StatusBar 类关联的 PopStatusText()函数。 PopStatusText()函数仅用于将文本恢复到上次调用 PushStatusText 之前的值。

请注意,如果同时调用了 SetStatusText,PopStatusText 将不会更改文本,即它不会覆盖对状态文本的显式更改,而只会恢复已保存的文本(如果此后未更改)。

编码示例:

import wx
  
  
class Example(wx.Frame):
  
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
  
        self.InitUI()
  
    def InitUI(self):
  
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
        self.statusbar = wx.StatusBar()
        self.statusbar.Create(self, id = 1, style = wx.STB_DEFAULT_STYLE, 
                                                      name = "Status Bar")
        self.SetStatusBar(self.statusbar)
        self.SetSize((350, 250))
  
        self.statusbar.SetFieldsCount(2)
        self.statusbar.SetStatusWidths([150, 150])
        self.statusbar.SetStatusText("This is text after stack pop in field 1", 0)
        self.statusbar.SetStatusText("This is text after stack pop in field 2", 1)
        self.statusbar.SetStatusStyles(styles =[wx.SB_RAISED, wx.SB_SUNKEN])
          
        # PUSH TEXT IN STATUS TEXT STACK
        self.statusbar.PushStatusText(string ="This is pushed text for field 1", field = 0)
        self.statusbar.PushStatusText(string ="This is pushed text for field 2", field = 1)
          
        # POP TEXT IN STATUS TEXT STACK
        self.statusbar.PopStatusText(field = 0)
          
        self.statusbar.PopStatusText(field = 1)
        self.SetTitle('New Frame Title')
        self.Centre()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
