wxPython wx.StatusBar PopStatusText()用法及代码示例


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为上次调用PushStatusText之前的值。

请注意,如果同时调用了SetStatusText,则PopStatusText不会更改文本,即,它不会覆盖对状态文本的显式更改,而是仅恢复自此以来未更改的已保存文本。

用法: wx.StatusBar.PopStatusText(self, field=0)

参数:

参数 输入类型 描述
field int 字段位置从0开始。

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()
