from VideoCapture import Device

    def onIdle(self, event):   
        img = self.cap.getImage(boldfont=1,timestamp=3)
        event.RequestMore()
     
    def OnGetCameraButton(self, event):#获取视频
        #-----INIT camera--------
        try:
            self.cap = Device(devnum=0,showVideoWindow=1)
            #Init Resolution
            self.cap.setResolution(320,240)
            self.Bind(wx.EVT_IDLE, self.onIdle)
        except Exception,e:
            text = "Do not detect camera device..."
            wx.MessageDialog(None,text,'alarm',wx.OK).ShowModal()
        event.Skip()
        
        #self.BigWindow是这个BUTTON的name值,self.Big_to_Small是一个Flag值        
    def OnBigWindowButton(self, event):#大小窗口互转
        if self.Big_to_Small == 0:
            self.cap.setResolution(640,480)
            self.Bind(wx.EVT_IDLE, self.onIdle)
            self.BigWindow.SetLabel(u'恢复小窗口')
            self.Big_to_Small =1
        else:

        event.Skip()

            self.cap.saveSnapshot("c:\\temp.jpg",boldfont=1,timestamp=3)
