I'm porting a class from C++ to Python. Everything is working fine, but
my TransferDataToWindow / TransferDataFromWindow are not called. What do
I have to do to get these methods called as they are on C++?
Markus
This is the code I use:
class FrameDialog(wxDialog):
def __init__(self, parent):
wxDialog.__init__(self, parent, -1, 'Neuen Rahmen erzeugen')
... other initialisation ...
def TransferDataToWindow(self):
print '********** TRANSFERDATATOWINDOW CALLED **********'
def TransferDataFromWindow(self):
print '********** TRANSFERDATAFROMWINDOW CALLED **********'
···
----------------------------------------------------------------------
in the other sourcefile:
dlg = FrameDialog(self)
if dlg.ShowModal() == wxID_OK:
..... etc ..........

Infact, I even despairingly tried to set this style for all frames in my
whole application, but with no effect whatsoever.

You need to set the extra style
self.SetExtraStyle(wx.WS_EX_VALIDATE_RECURSIVELY)
for your panel or frame (the "master parent object" holding your controls).

I'm porting a class from C++ to Python. Everything is working fine, but
my TransferDataToWindow / TransferDataFromWindow are not called. What do
I have to do to get these methods called as they are on C++?
It takes extra work to allow virtual C++ methods to be overridden in Python derived classes. It adds some runtime overhead and a lot of maintainance overhead so I only do it for classes/methods that need it in order to function normally. (IOW, pure virtuals or virtuals that should almost always be overridden.)
What are you wanting to put in the Transfer methods? There is probably another way to do it.

In this example, TransferDataToWindow is called immediately before the
window is shown (inside ShowModal), so I can call additional methods
inbetween the constructor and the call to ShowModal. Likewise, I don't
need to override the OnOK function, because TransferDataFromWindow is
automatically called when OK is pressed.
It's just a very handy mechanism, and I'd have to rewrite my dialogs if
this wouldn't work in wxPython.
Also, the release notes for 2.3.3.1 say that it should work:

I'm using something like the following (which is just because it was
like this in the C++ implementation):

Also, the release notes for 2.3.3.1 say that it should work:
As the release notes say, it is just for wxPyWindow, wxPyPanel and wxPyControl which are custom classes derived from wxWindow, wxPanel, and wxControl and are engineered as described above to allow those methods to be overridden. I suppose I could do the same for a wxPyDialog class, but currently that is not done and so you'll have to workaround it for now anyway. There are probably some events that you can catch that will give you nearly the same functionality. (Try EVT_SHOW.)

I am using dialogs with controls which are filled with data from a database through validators. I call in appropriate places of the code self.InitDialog() whenever you need TransferToWindow to be called.
See you
