从动态创建的 wx.checkbox 获取值 [英] Get value from dynamically created wx.checkbox

问题描述

这段代码(感谢 Mike Driscoll)创建了一个由 168 个复选框组成的网格，每天每个小时一个.在检索它们的值时我被卡住了......我想得到一个像 {mon1 : yes} 等的字典.任何帮助表示赞赏...

This code (thanks Mike Driscoll) creates a grid of 168 checkboxes, one for every hour of everyday. I am stuck when it comes to retrieving their values... I would like to get a dict like {mon1 : yes} etc. Any help appreciated...

import wx

class MainPanel(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent)

        main_sizer = wx.BoxSizer(wx.VERTICAL)

        for row in range(7):
            row_sizer = wx.BoxSizer(wx.HORIZONTAL)
            for col in range(24):
                name_of_checkbox = "row_{row}_col_{col}".format(row=row, col=col)
                checkbox = wx.CheckBox(self, name=name_of_checkbox)
                row_sizer.Add(checkbox, 0, wx.ALL, 5)
            main_sizer.Add(row_sizer)

        self.SetSizer(main_sizer)


class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, title='Hours and days', size=(650, 400))
        panel = MainPanel(self)
        self.Show()


if __name__ == '__main__':
    app = wx.App()
    frame = MainFrame()
app.MainLoop()

推荐答案

您可以创建一个结构来保存复选框 ID，并添加一个按钮来一次检索所有数据.这样可以轻松访问哪些框已被选中，哪些没有被选中.通过这种方式，您可以以您喜欢的任何结构检索数据，例如:

You can create a structure to hold the check box id's and add a button to retrieve all of the data at once. This makes it easy to access which boxes have been checked and which haven't. This way you can retrieve the data in any structure you like i.e. something like this:

import wx

class MainPanel(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent)

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        days=['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
        self.boxes=[]
        for row in range(7):
            row_sizer = wx.BoxSizer(wx.HORIZONTAL)
            day = days[row]
            for col in range(24):
                name_of_checkbox = "{day}_{hour}".format(day=day, hour=col)
                self.checkbox = wx.CheckBox(self, name=name_of_checkbox)
                row_sizer.Add(self.checkbox, 0, wx.ALL, 5)
                self.boxes.append(self.checkbox)
            main_sizer.Add(row_sizer)
        button = wx.Button(self,-1,"Retrieve Data")
        main_sizer.Add(button)
        self.Bind(wx.EVT_CHECKBOX, self.OnChecked)
        self.Bind(wx.EVT_BUTTON, self.OnGetData)
        self.SetSizer(main_sizer)

    def OnChecked(self,event):
        clicked = event.GetEventObject()
        print clicked.GetName()
        print event.IsChecked()

    def OnGetData(self,event):
        day_dict = {}
        day_list = []
        for i in self.boxes:
            if i.IsChecked():
                n = i.GetName()
                day_dict[n]="Checked"
                day_list.append((n,"Checked"))
        print day_dict
        print day_list

class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, title='Hours and days', size=(850, 400))
        panel = MainPanel(self)
        self.Show()


if __name__ == '__main__':
    app = wx.App()
    frame = MainFrame()
app.MainLoop()
