Question

I’ve created a wxframe with a button which when clicked brings up a child frame that generates text controls with data stored from a dictionary named “samples” as shown below. The idea of the child frame is that it is an edit window for editing the data.

My problem is I don’t know how to retrieve data from the generated text controls. I can only get data from the last generated text control.

Here is a simplified version of the code I created:

import wx

class MyFrame1(wx.Frame):


    def __init__(self, *args, **kwds):
        # begin wxGlade: MyFrame1.__init__
        kwds["style"] = wx.DEFAULT_FRAME_STYLE
        self.frame=wx.Frame.__init__(self, *args, **kwds)
        self.panel_1 = wx.Panel(self, -1)
        self.f3 = wx.Frame(None,-1,'Edit Tags')

        self.editTag = wx.Button(self.panel_1, -1, "Edit Tags", size=(100, 50))
        self.editTag.Bind(wx.EVT_BUTTON, self.editTags)

        self.Bind( wx.EVT_CLOSE, self.CloseAll)



        # end wxGlade

#-------------------------------------------------------------------------------
    def editTags(self, event):  # wxGlade: MyFrame.<event_handler>
        samples={
              "Face1":"(100,100)", \
              "Face2":"(50,40)", \
              "Car":"(500,230)", \
              "Wallclock":"(120,230)"

            }

        self.f3.okButton = wx.Button(self.f3, label="OK")
        self.f3.okButton.Bind(wx.EVT_BUTTON, self.onOK)
        self.f3.okButton.SetPosition((40,200))

        spacer=0

        for k, v in sorted(samples.iteritems()):
            print "K: ", k

            spacer=spacer+40
            print "V: ", v
            print

        self.f3.new_TextControl = wx.TextCtrl(self.f3, -1, value=k)
        self.f3.new_TextControl.SetPosition((40,spacer))

        print

        self.f3.Show()

   #-------------------------------------------------------------------------------
    def onOK(self, event):  # wxGlade: MyFrame.<event_handler>
        print self.f3.new_TextControl.GetValue()
        print self.f3.new_TextControl.GetValue()
        print "OK clicked"
        self.f3.Hide()
   #-------------------------------------------------------------------------------

    def CloseAll(self, event):
        self.DestroyChildren()  # First destroy child frames
        self.Destroy()          # Then destroy the parent frame
        self.f3.Close()
        self.Close()
   #-------------------------------------------------------------------------------

    # end of class MyFrame1
    if __name__ == "__main__":
        app = wx.PySimpleApp(0)
        frame_1 = MyFrame1(None, -1, "")
        app.SetTopWindow(frame_1)
        frame_1.Show()
        app.MainLoop()

Any alternative solutions are welcome as well

I’m using python 2.7.2. and wxpython

Let’s look through your code:

def editTags(self, event):  # wxGlade: MyFrame.<event_handler>
    samples={
          "Face1":"(100,100)", \
          "Face2":"(50,40)", \
          "Car":"(500,230)", \
          "Wallclock":"(120,230)"

        }

    self.f3.okButton = wx.Button(self.f3, label="OK")
    self.f3.okButton.Bind(wx.EVT_BUTTON, self.onOK)
    self.f3.okButton.SetPosition((40,200))

Let’s make a storage for your new controls (will discuss it below):

    self.f3.new_controls = {}

    spacer=0

Here you iterate over your future fields and here’s a problem:

    for k, v in sorted(samples.iteritems()):
        print "K: ", k

        spacer=spacer+40
        print "V: ", v
        print

The next step: you actually create your controls. Here is where some issues hide:

1. You create it out of your cycle, you must put them inside for-loop block (in your variant only one text control (stored in new_TextControl field is created)), and it will be a field for the last iterated v value (that’s how for works).
2. You need to create some container (remember self.f3.new_controls we created above?) to hold your controls (e.g. a dict).

So let’s make some further changes to your code:

        # Dict will hold {'Car': wx.TextCtrl(...), 'Wallclock': ...}
        self.f3.new_controls[k] = wx.TextCtrl(self.f3, -1, value=k)
        self.f3.new_controls[k].SetPosition((40,spacer))

And you show your frame, that’s ok:

    self.f3.Show()

You can access values of newly created fields from new_controls dict:

self.f3.new_controls['Car'].GetValue()  # Receive input from 'Car' text control.
