在这段代码中,我有一个wx TextCtrl来显示信息(info_window),还有一个函数print_info()来接收来自我的主脚本的文本,将它们附加到TextCtrl。文本同时附加,但我需要将它们添加为:
你好1
- 按任意键
你好2
- 按任意键
你好3
用键盘按任意键后,有没有办法逐个追加字符串?
我认为键应该是函数press_any_key()。它可能与任何类型的wx事件有关,但我不知道如何正确编写该函数。
import wx
class Frame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__ (self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size(500,300), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL)
self.SetSizeHints(wx.DefaultSize, wx.DefaultSize)
bSizer1 = wx.BoxSizer(wx.VERTICAL)
self.info_window = wx.TextCtrl(self, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.Size(450,250), wx.TE_MULTILINE|wx.TE_READONLY|wx.TE_RICH2)
bSizer1.Add(self.info_window, 0, wx.ALL, 5)
self.SetSizer(bSizer1)
self.Layout()
def print_info(self, string):
self.string = string + '\n'
self.info_window.AppendText(self.string)
self.press_any_key()
def press_any_key(self):
pass
def main():
frame.print_info('hello 1')
frame.print_info('hello 2')
frame.print_info('hello 3')
app = wx.App()
frame = Frame(None)
frame.Show()
main()
app.MainLoop()
感谢萨克森的罗尔夫。我解决了我的问题,关键点是wx.Yield()。我修改了以下代码
import wx
import time
class Frame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__ (self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size(500,300), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL)
self.SetSizeHints(wx.DefaultSize, wx.DefaultSize)
bSizer1 = wx.BoxSizer(wx.VERTICAL)
self.info_window = wx.TextCtrl(self, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.Size(450,250), wx.TE_MULTILINE|wx.TE_READONLY|wx.TE_RICH2)
bSizer1.Add(self.info_window, 0, wx.ALL, 5)
self.info_window.Bind(wx.EVT_KEY_DOWN, self.go)
self.SetSizer(bSizer1)
self.Layout()
self.go_status = False
def print_info(self, string):
self.waitkey()
self.string = string + '\n'
self.info_window.AppendText(self.string)
self.go_status = False
def go(self, event):
self.go_status = True
def waitkey(self):
while self.go_status == False:
wx.Yield()
time.sleep(0.1)
def main():
frame.print_info('hello 1')
frame.print_info('hello 2')
frame.print_info('hello 3')
app = wx.App()
frame = Frame(None)
frame.Show()
main()
app.MainLoop()
答案 0 :(得分:0)
它不漂亮,但我想不出更简单的方法。
import wx
import time
class Frame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__ (self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size(500,360), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL)
self.SetSizeHints(500,360)
bSizer1 = wx.BoxSizer(wx.VERTICAL)
self.info_window = wx.TextCtrl(self, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.Size(450,250), wx.TE_MULTILINE|wx.TE_READONLY|wx.TE_RICH2)
self.message = wx.StaticText(self,-1,("Press any key"))
self.keyinput = wx.TextCtrl(self,-1)
bSizer1.Add(self.info_window, 0, wx.ALL, 5)
bSizer1.Add(self.message, 0, wx.ALL, 5)
bSizer1.Add(self.keyinput, 0, wx.ALL, 5)
self.SetSizer(bSizer1)
self.Layout()
self.Show()
self.keyinput.SetFocus()
def print_info(self, string):
self.WaitOnKey()
self.string = string + '\n'
self.info_window.AppendText(self.string)
def WaitOnKey(self):
while self.keyinput.GetValue() == "":
wx.Yield()
time.sleep(0.2)
self.keyinput.SetValue("")
def main():
frame.print_info('hello 1')
frame.print_info('hello 2')
frame.print_info('hello 3')
app = wx.App()
frame = Frame(None)
main()
app.MainLoop()
除wx.Yield()
外,代码是自解释的。这会将控制权返回给MainLoop
,这意味着程序不会冻结。基本上当程序等待键输入时,控制每隔2/10秒传回主循环,以查看是否还有其他事情发生。这允许程序继续正常执行。
注意:这不适用于功能键。为此,我认为您必须找到bind
关键事件的方法并使用event.GetKeyCode()
