Sharing Events and Data Between Frames

Greetings –

I guess my previous post was too lengthy!

Is superclassing the best way to share data between frames
in a single application?

What about events? For example:

If I have a frame with a text box
and a button, how can I make the button update ‘send’ an update to
another frame with a text box?

I have an OnClick that does a
GetValue on the text box. How can I use that to SetValue the other text box in
a different frame?

Any guidance would be GREATLY appreciated,

Hi Hal,

Just use a reference to the other frame. Here is a small example showing you how to do it:

#----------------------start-----------
import wx

class FrameBase(wx.Frame):
def init(self, title):

    wx.Frame.__init__(self, None, title=title)
    self.txt = wx.TextCtrl(self)
    self.txt.Bind(wx.EVT_TEXT, self.OnText)

def OnText(self, evt):
    if 'otherFrame' in dir(self):

        self.otherFrame.txt.SetValue(self.txt.GetValue())
    evt.Skip()

if name ==“main”:
app = wx.App(0)
f1 = FrameBase(“Frame One”)
f2 = FrameBase(“Frame Two”)

f2.otherFrame = f1 #the reference ;)
f1.Show()
f2.Show()
app.MainLoop()

#----------------------the end-----------

Typing in the Frame2 will automaticaly update in the Frame1.

Peter.

Depending on how large and complex you expect your app to be you might want to begin investigating organizing it around a MVC (Model-View-Controller) pattern.

   http://wiki.wxpython.org/index.cgi/ModelViewController

The app I'm doing right now has grown large enough that it would have been impossible to organize all the gui-gui and gui-data interactions without MVC. That said, I think some of the stuff people do in MVC goes too far. IMHO.

In any case, you'll probably learn a lot by reading up on it.
