[wxPython] "Could not transfer data to window"

wxPython Users

I get this odd error message, "Could not transfer data to window". This
is when I load one of my dialog boxes with ShowModal. Does anyone have
an idea what I'm looking for, before I go on a big debugging mission?

Thanks,
Hugo

i dont know your problem - but : 'WHICH DEBUGGER would you use ???" - I
dont
know any debugger for python which is stable enough to work with it.

From the validators overview:

"
When a wxDialog::Show is called (for a modeless dialog) or
wxDialog::ShowModal is called (for a modal dialog), the function
wxWindow::InitDialog is automatically called. This in turn sends an
initialisation event to the dialog. The default handler for the
wxEVT_INIT_DIALOG event is defined in the wxWindow class to simply call the
function wxWindow::TransferDataToWindow. This function finds all the
validators in the window's children and calls the TransferToWindow function
for each. Thus, data is transferred from C++ variables to the dialog just as
the dialog is being shown."

So, are you perhaps mistakenly supplying too many arguments to the wx*Dialog
constructor, and supplying an invalid value for the validator argument? Or
something like that? [Sorry, I've had this problem in the past but can't
remember my specific fix... not that left would necessarily be useful in
your case anyway...]

Hope you sort things out...

Your validators need to implement TransferToWindow and TransferFromWindow
and return true from them.
