wxPython – wx.StatusBar 中的 SetFieldsCount()函数

在本文中，我们将学习与 wxPython 的 wx.StatusBar 类关联的 SetFieldsCount()函数。 SetFieldsCount()函数仅用于设置字段数，以及可选的字段宽度。
它需要两个参数来设置字段数和相应字段的宽度列表。

Syntax: wx.StatusBar.SetFieldsCount(self, number=1, widths=None)

Parameters:

Parameter	Input Type	Description
number	int	The number of fields. If this is greater than the previous number, then new fields with empty strings will be added to the status bar.
widths	list of ints	An array of n integers interpreted in the same way as in SetStatusWidths.

代码示例：

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))
          
        # SET TOTAL NUMBER OF FIELDS AND RESPECTIVE WIDTHS
        self.statusbar.SetFieldsCount(3, [100, 80, 60])
  
        # SET TEXT FOR ALL FIELDS
        self.statusbar.SetStatusText("Field One", 0)
        self.statusbar.SetStatusText("Field Two", 1)
        self.statusbar.SetStatusText("Field Three", 2)
  
        self.SetTitle('New Frame Title')
        self.Centre()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
