Strange error.

I have made a simple app in wxPython with Boa, when the user pressess a button, a text is copied from an TextCtrl to a Label.

The following code stands in the button event:

Code:

Label.label = Text.value

Label is the Label
Text is the TextCtrl

They both exist, but it says that they do not exist.

Yo yo old bean,

Your gonna have to give us a little more info. Can you post the actual error message or attach the code so those with wxPython and or Boa can see whats going on for themselves. It's just a tad hard to see whats happening from two lines of code

Ok, my mistake, you appear to need the Boa to run this, I thought it was just a program? ah well sorry cant really help to much, you could post the error message though.

Problem solved, The error was being caused because "gloabl Text does not exist" and it doesn't, you do have self.Text though. I changed the line..

Label.label = Text.value

to..

Label.label = self.Text.value

and it works fine.

Hope this helps!

EDIT: closer examination and it isnt accessing the value. But the window shows up. Apparently wxTextCtrl has no attrabute value

Have fun,
Mark.

We'll thats just the error i was getting, i have very little exp with GUI programming. The fact was, Python was complaining that it has no value attrabute which means it couldn't find one!

Sorry dude I don't know. If I'm getting this right all your trying to do is get input from the entry box and display it, obviously there is an error in the way your trying to do this..

Not knowing wxPython, not having looked at the documentation, I can offer you little qualified help in ultimately solving your problem. On the other hand, I know what you are doing wrong.

It is true that there is no 'Text' attribute in the global namespace. On the other hand, there is a 'Text' attribute in the instance namespace. The same goes for the 'Label' attribute, btw. You have to access all instance data objects by explicitly prefixing 'self.'

Code:

def OnButton1Button(self, event):
        self.Label = wxStaticText(id=wxID_WXFRAME1LABEL,
       	        label=self.Text.GetValue(), name='Label', parent=self,
       	        pos=wxPoint(8, 40), size=wxSize(95, 13), style=0)
       	self.Validate()

The above piece of code will paint what you write on top of the previous text. As I said, not much help, but perhaps it'll get you moving.

Solved! Thanks for code.

This is the solution that i used:

Code:

self.Label.SetLabel(self.Text.GetValue())

And it worked correctly.
