在pyProgress中按下取消按钮时如何设置

Question

您好，我使用 wxpython 4 和 windows10。我想将 PyProgress (AGW) 与 Cancel button 集成到我的应用程序中，我想要这个按钮 Cancel把我的应用程序 Paused。除了我添加了取消按钮但它不可点击并且我无法与该按钮绑定暂停功能。

import wx.lib.agw.pyprogress as PP

def onButton(self, event):
        """
        Based on the wxPython demo by the same name
        """
        event.Skip()
        dlg = PP.PyProgress(None, -1, "Demo", "Demo in progress", agwStyle=wx.PD_APP_MODAL | wx.PD_ELAPSED_TIME | wx.PD_CAN_ABORT)
        dlg.SetGaugeProportion(0.2)
        dlg.SetGaugeSteps(50)
        dlg.SetGaugeBackground(wx.WHITE)
        dlg.SetFirstGradientColour(wx.WHITE)
        dlg.SetSecondGradientColour(wx.BLUE)
        max = 400
        keepGoing = True
        count = 0

        while keepGoing and count < max:
            count += 1
            wx.MilliSleep(30)

            if count >= max / 2:
                keepGoing = dlg.UpdatePulse("Half-time!")
            else:
                keepGoing = dlg.UpdatePulse()

        dlg.Destroy()

#if(wx.PD_CAN_ABORT):
#execute onPause(event)


def onPause(self, event):
???

PyProgress 似乎不再有可操作的 Cancel 按钮。
请改用 wx.ProgressDialog 或 wx.Gauge。

如果您不想使用暂停功能，请使用如下方式：

import wx

class PyProgressDemo(wx.Frame):
    def __init__(self, parent):
        super().__init__(parent)

        self.panel = wx.Panel(self, -1)
        self.startbutton = wx.Button(self.panel, -1, "Start PyProgress!")
        self.startbutton.Bind(wx.EVT_BUTTON, self.onButton)
        vbox = wx.BoxSizer(wx.VERTICAL)
        vbox.Add(self.startbutton)
        self.panel.SetSizer(vbox)
        self.Show()

    def onButton(self, event):
            self.dlg = wx.ProgressDialog('Search personal Data', 'Analyse en cours..', style= wx.PD_ELAPSED_TIME | wx.PD_CAN_ABORT)
            max = 400
            keepGoing = True
            count = 0
            while keepGoing and count < max:
                count += 1
                wx.MilliSleep(30)

                if count >= max / 2:
                    (keepGoing, skip) = self.dlg.Pulse("Half-time!")
                else:
                    (keepGoing, skip) = self.dlg.Pulse()

            self.dlg.Destroy()

app = wx.App()
prog = PyProgressDemo(None)
app.MainLoop()

如果你想要一个 Pause 函数，我认为你必须使用 Freeze 选项，像这样：

import wx

class PyProgressDemo(wx.Frame):
    def __init__(self, parent):
        super().__init__(parent)

        self.panel = wx.Panel(self, -1)
        self.startbutton = wx.Button(self.panel, -1, "Start PyProgress!")
        self.stopbutton = wx.Button(self.panel, -1, "Pause/Unpause PyProgress!")
        self.startbutton.Bind(wx.EVT_BUTTON, self.onButton)
        self.stopbutton.Bind(wx.EVT_BUTTON, self.onPause)
        vbox = wx.BoxSizer(wx.VERTICAL)
        vbox.Add(self.startbutton)
        vbox.Add(self.stopbutton)
        self.panel.SetSizer(vbox)
        self.Show()

    def onButton(self, event):
            self.dlg = wx.ProgressDialog('Search personal Data', 'Analyse en cours..', style= wx.PD_ELAPSED_TIME | wx.PD_CAN_ABORT)
            max = 400
            keepGoing = True
            count = 0

            try:
                while keepGoing and count < max:
                    if self.dlg.IsFrozen():
                        wx.Yield()
                        wx.MilliSleep(30)
                        continue
                    count += 1
                    wx.MilliSleep(30)

                    if count >= max / 2:
                        (keepGoing, skip) = self.dlg.Pulse("Half-time!")
                    else:
                        (keepGoing, skip) = self.dlg.Pulse()

                self.dlg.Destroy()
            except:
                pass

    def onPause(self, event):
        try:
            if self.dlg.IsFrozen():
                self.dlg.Thaw()
            else:
                self.dlg.Freeze()
        except:
            pass

app = wx.App()
prog = PyProgressDemo(None)
app.MainLoop()
