wxpython-我们可以在 pybusyinfo 对话框上添加确定按钮吗？

Question

我已经创建了 pybusyinfo 对话框来显示消息，并且在睡眠 30 秒后它会自动关闭。

现在我需要在该对话框中添加确定按钮以获取用户输入并且他们没有按下按钮对话框应在 30 秒内关闭。

我们可以将该按钮添加到 wx.lib.agw.pybusyinfo 对话框中吗？

或者有没有其他wx widgets的对话框会在一段时间后自动关闭？

import wx
import wx.lib.agw.pybusyinfo as PBI
retVal = showmsg("dialog will be closed in 30 secs...")
time.sleep(30)
retVal = None

def showmsg(msg):
    app = wx.App(redirect=False)
    title = 'Message!'
    retVal = PBI.PyBusyInfo(msg, title=title)
    return retVal

编写您自己的忙碌对话框，其中包含一个指示忙碌的仪表。
使用 wxTimer 循环测量。
这应该让你开始：

import wx
class MyFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent, -1, "Busy Dialog",size=(500,200))
        self.panel = wx.Panel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        self.log = wx.TextCtrl(self.panel, wx.ID_ANY, size=(400,100),style = wx.TE_MULTILINE|wx.TE_READONLY|wx.VSCROLL)
        self.button = wx.Button(self.panel, label="Click me")
        sizer.Add(self.log, 0, wx.EXPAND | wx.ALL, 10)
        sizer.Add(self.button, 0, wx.EXPAND | wx.ALL, 10)
        self.panel.SetSizer(sizer)
        self.Bind(wx.EVT_BUTTON, self.OnButton)

    def OnButton(self,event):
        dlg = Busy(parent = self.panel) 
        dlg.ShowModal()
        if dlg.result_text:
            self.log.AppendText("Text Input: "+dlg.result_text+"\n")
        dlg.Destroy()

class Busy(wx.Dialog):
    def __init__(self, parent):
        wx.Dialog.__init__(self, parent, wx.ID_ANY, "Busy", size= (420,240))
        self.panel = wx.Panel(self,wx.ID_ANY)
        self.label = wx.StaticText(self.panel, label="Input", pos=(20,20))
        self.textinput = wx.TextCtrl(self.panel, value="", pos=(80,20), size=(300,-1))
        self.gauge = wx.Gauge(self.panel,size=(300,20),pos=(80,80), style=wx.GA_HORIZONTAL)
        self.livelabel = wx.StaticText(self.panel, label="Time to live:", pos=(80,110))
        self.lltime = wx.StaticText(self.panel, label="30", pos=(160,110))
        self.saveButton =wx.Button(self.panel, label="Save Input", pos=(80,160))
        self.closeButton =wx.Button(self.panel, label="Cancel", pos=(180,160))
        self.timeoutButton =wx.Button(self.panel, label="Timer Off", pos=(280,160))
        self.saveButton.Bind(wx.EVT_BUTTON, self.SaveBusyString)
        self.closeButton.Bind(wx.EVT_BUTTON, self.OnQuit)
        self.timeoutButton.Bind(wx.EVT_BUTTON, self.OnNoTimeout)
        self.Bind(wx.EVT_CLOSE, self.OnQuit)
        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER,self.OnTimer, self.timer)
        self.lifetimer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER,self.OnLifeTimer, self.lifetimer)
        self.timer.Start(100)
        self.lifetimer.Start(1000)
        self.timeoutbutton_pressed = False
        self.gauge.SetBackgroundColour(wx.Colour(0, 127, 255, 255)) #Slate Blue
        self.gauge.SetRange(100)
        self.gauge.SetValue(0)
        self.life = 30
        self.direction = 1
        self.Show()

    def OnTimer(self, evt): #Update gauge
        x = int(self.gauge.GetValue())
        if x == 0:
            self.direction = 1
        elif x == 100:
            self.direction = -1
        x+=self.direction
        self.gauge.SetValue(x)

    def OnLifeTimer(self, evt): #Update time to live
        if self.timeoutbutton_pressed == True:
            return
        self.life -= 1
        self.lltime.SetLabelText(str(self.life))
        if self.life < 1:
            self.OnQuit(None)

    def OnNoTimeout(self, evt): # toggle time to live
        if self.timeoutbutton_pressed == False:
            self.timeoutbutton_pressed = True
            self.timeoutButton.SetLabel("Timer On")
        else:
            self.timeoutbutton_pressed = False
            self.timeoutButton.SetLabel("Timer Off")

    def OnQuit(self, event):
        self.timer.Stop()
        self.lifetimer.Stop()
        self.result_text = None
        self.Destroy()

    def SaveBusyString(self, event): # return input
        self.result_text = self.textinput.GetValue()
        self.timer.Stop()
        self.lifetimer.Stop()
        self.Destroy()

app = wx.App()
frame = MyFrame(None)
frame.Show()
app.MainLoop()

编辑：
你需要一个框架，因为对话框需要父级，所以最简单的方法是制作一个你看不到的框架。
把上面的 MyFrame class 去掉，把 app 部分的代码改成这样：

app = wx.App()
frame = wx.Frame(None,-1,"",size=(1,1))
frame.Show()
dlg = Busy(parent = frame)
dlg.ShowModal()
print dlg.result_text # Do whatever here with the result I just print it
dlg.Destroy()
