wxpython dataray接口相机

Question

我目前正在尝试修改本页教程中给出的示例，该示例生成如下所示的 GUI。（示例教程第二页可自行下载）

运行此代码与 Python 2.7 和 wxPython 和 Comtypes 将打开一个类似于教程最后一页的 GUI，它给出了光束的属性轻.

import wx
import wx.lib.activex
import csv
import comtypes.client

class EventSink(object):

    def __init__(self, frame):
        self.counter = 0
        self.frame = frame

    def DataReady(self):
        self.counter +=1
        self.frame.Title= "DataReady fired {0} times".format(self.counter)


class MyApp( wx.App ): 

    def OnClick(self,e):
        rb_selection = self.rb.GetStringSelection()
        if rb_selection == "WinCam":
            data = self.gd.ctrl.GetWinCamDataAsVariant()
            data = [[x] for x in data]
        else:
            p_selection = self.cb.GetStringSelection()
            if p_selection == "Profile_X":
                data = self.px.ctrl.GetProfileDataAsVariant()
                data = [[x] for x in data]#csv.writerows accepts a list of rows where each row is a list, a list of lists
            elif p_selection == "Profile_Y":
                data = self.py.ctrl.GetProfileDataAsVariant()
                data = [[x] for x in data]
            else:
                datax = self.px.ctrl.GetProfileDataAsVariant()
                datay = self.py.ctrl.GetProfileDataAsVariant()
                data = [list(row) for row in zip(datax,datay)]#Makes a list of lists; X1 with Y1 in a list, X2 with Y2 in a list etc...
        filename = self.ti.Value
        with open(filename, 'wb') as fp:
            w = csv.writer(fp, delimiter=',')
            w.writerows(data)

        #The methods of the object are available through the ctrl property of the item
        self.gd.ctrl.StartDriver()
        self.counter = 0
        sink = EventSink(self.frame)
        self.sink = comtypes.client.GetEvents(self.gd.ctrl, sink)

        #Custom controls
        t = wx.StaticText(bp, label="File:", pos=(5, 115))
        self.ti = wx.TextCtrl(bp, value="C:\Users\Public\Documents\output.csv", pos=(30, 115), size=(170, -1))

        myb.Bind(wx.EVT_BUTTON, self.OnClick)
        #Pictures
        pic = wx.lib.activex.ActiveXCtrl(parent=self.frame,size=(250,250),axID='DATARAYOCX.CCDimageCtrl.1')

        #Profiles
        self.px = wx.lib.activex.ActiveXCtrl(parent=self.frame,size=(300,200),axID='DATARAYOCX.ProfilesCtrl.1')
        self.px.ctrl.ProfileID=22
        self.py = wx.lib.activex.ActiveXCtrl(parent=self.frame,size=(300,200),axID='DATARAYOCX.ProfilesCtrl.1')
        self.py.ctrl.ProfileID = 23
        #Formatting 
        row1 = wx.BoxSizer(wx.HORIZONTAL)
        row1.Add(item=bp,flag=wx.RIGHT, border=10)
        row1.Add(pic)
        row1.Add(item=tpic, flag=wx.LEFT, border=10)
        row2 = wx.BoxSizer(wx.HORIZONTAL)
        row2.Add(self.px, 0, wx.RIGHT, 100)# Arguments: item, proportion, flags, border
        row2.Add(self.py)
        col1 = wx.BoxSizer(wx.VERTICAL)
        col1.Add(item=row1, flag=wx.BOTTOM, border=10)
        col1.Add(item=row2, flag=wx.ALIGN_CENTER_HORIZONTAL)
        self.frame.SetSizer(col1)
        self.frame.Show()

if __name__ == "__main__":
     app = MyApp()
     app.MainLoop()

基本上，我的目标是从按钮中提取数据并将其写入文件或将其编译为列表，但我不知道使用什么命令来访问该数据。

我知道大多数人无法访问我正在使用的硬件，但我的问题更侧重于带按钮的 wxPython 控件，以及如何获取该数据。

如果有帮助，这里是相机的 OCX 控件的文档。

DataRay OCX Documentation

如果有我可以回答的问题，请告诉我。提前感谢您的时间和帮助。

Answer 1

根据文档，它应该 return 一个包含内容的双精度值，例如b1.ctrl.GetParameter() 按钮 b1.

这当然需要存储按钮对象，例如在 MyApp 对象中。
