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)。
Syntax: wx.StatusBar.PopStatusText(self, field=0)
Parameters:
Parameter | Input Type | Description |
---|---|---|
field | int | Field Position starting from 0. |
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()
