Python WX - Returning user input from wx Dialog

boa-constructor, python, wxpython, wxwidgets

Solution

There are lots of dialog examples out there. Here are a couple:

- The Dialogs of wxPython (Part 1 of 2)

- http://zetcode.com/wxpython/dialogs/

Basically, all you need to do is instantiate your dialog, show it and then before you close it, extract the value. The typical way to do it is something like this:

myDlg = MyDialog()
res = myDlg.ShowModal()
if res == wx.ID_OK:
    value = myDlg.myCombobox.GetValue()
myDlg.Destroy()

Update: Here's a more full-fledged example:

import wx

########################################################################
class MyDialog(wx.Dialog):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Dialog.__init__(self, None, title="Dialog")

        self.comboBox1 = wx.ComboBox(self, 
                                     choices=['test1', 'test2'],
                                     value="")
        okBtn = wx.Button(self, wx.ID_OK)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.comboBox1, 0, wx.ALL|wx.CENTER, 5)
        sizer.Add(okBtn, 0, wx.ALL|wx.CENTER, 5)
        self.SetSizer(sizer)

########################################################################
class MainProgram(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Main Program")
        panel = wx.Panel(self)

        btn = wx.Button(panel, label="Open dialog")
        btn.Bind(wx.EVT_BUTTON, self.onDialog)

        self.Show()

    #----------------------------------------------------------------------
    def onDialog(self, event):
        """"""
        dlg = MyDialog()
        res = dlg.ShowModal()
        if res == wx.ID_OK:
            print dlg.comboBox1.GetValue()
        dlg.Destroy()

if __name__ == "__main__":
    app = wx.App(False)
    frame = MainProgram()
    app.MainLoop()

Problem

I'm new to Python and WX. I created a simple test dialog shown below that prompts the user with a combobox. I would like to capture the value from the combox in my main program. How do I call it from my main program? This is how I was purposing to call it that displays the dialog but does not currently capture the value from the combobox: ``` import highlight highlight.create(self).Show(True) a = highlight.OnComboBox1Combobox(self) print a ``` The name of the Dialog file is "highlight". Below is the code: ``` #Boa:Dialog:Dialog2 import wx def create(parent): return Dialog2(parent) [wxID_DIALOG2, wxID_DIALOG2COMBOBOX1, wxID_DIALOG2STATICTEXT1, ] = [wx.NewId() for _init_ctrls in range(3)] class Dialog2(wx.Dialog): def _init_ctrls(self, prnt): # generated method, don't edit wx.Dialog.__init__(self, id=wxID_DIALOG2, name='', parent=prnt, pos=wx.Point(264, 140), size=wx.Size(400, 485), style=wx.DEFAULT_DIALOG_STYLE, title='Dialog2') self.SetClientSize(wx.Size(384, 447)) self.comboBox1 = wx.ComboBox(choices=['test1', 'test2'], id=wxID_DIALOG2COMBOBOX1, name='comboBox1', parent=self, pos=wx.Point(120, 16), size=wx.Size(130, 21), style=0, value=u'wining\n') self.comboBox1.SetToolTipString(u'comboBox1') self.comboBox1.SetLabel(u'wining\n') self.comboBox1.Bind(wx.EVT_COMBOBOX, self.OnComboBox1Combobox, id=wxID_DIALOG2COMBOBOX1) self.staticText1 = wx.StaticText(id=wxID_DIALOG2STATICTEXT1, label=u'test', name='staticText1', parent=self, pos=wx.Point(88, 16), size=wx.Size(19, 13), style=0) def __init__(self, parent): self._init_ctrls(parent) ##print get_selection ##print get_selection1 def OnComboBox1Combobox(self, event): get_selection = self.comboBox1.GetValue() return get_selection ```
