XRCise says "Cannot create wrapper for subclass of wxWizard"

Desktop wxRuby
1

I have created a very simple DialogBlocks project that
consists of a very simple wxWizard. I have exported the
project to XRC and am trying to get XRCise to process it.
XRCise produces the message “Cannot create wrapper for
subclass of wxWizard”.

Is this a symptom of the XPath parsing in Ruby 1.8.6 bug?
Or am I doing something wrong?

My env:
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]
wxruby-1.9.2-i386-mswin32
wx_sugar 0.1.19
Windows XP Professional 5.1.2600

My XRC file:

<?xml version="1.0" encoding="UTF-8"?>


wxDEFAULT_DIALOG_STYLE|wxCAPTION|wxRESIZE_BORDER|wxSYSTEM_MENU|wxCLOSE_BOX
wxWIZARD_EX_HELPBUTTON
Me Wizard
wizard.png

wxTAB_TRAVERSAL
#FFFFFF
oooh.png

wxVERTICAL

wxGROW|wxALL
5

This is some static text.





Thank you kindly for any advice you can offer,
Peralta

Hi Peralta,

I use wxFormBuilder v3.0 and had the same error message.
But I found the solution.
For the topmost element “MyFrame1:Frame” in the object tree I can set
the value of a parameter “subclass”.
By default the value is “;” (probably for C++ use), and when I change it
to something like “blabla”, it works.

Cheers,

Thanks for the report. It’s because I don’t know how to load a Wizard
from XRC - currently only Dialog, Panel and Frame are supported.

There are lots of methods in the XmlResource API like load_frame,
load_panel etc, but not one it seems for wizards. Using load_dialog
doesn’t work although Wizard is technically a subclass of Wx::Dialog.

I will have a further look into this, but if anyone knows how to load a
Wizard in C++ wxWidgets, that would help…

cheers

Hello Herman,

I also use wxFormBuilder myself, and I ran into the same problem with
it. I
found this less annoying, as I just put in the class I plan to implement
all
my methods and such onto the Object in question, and this allows for
everything to work when utilizing xrcise. It actually makes it a bit
simpler to keep track of what object is what. Heh.

L8ers,

Mario S.

Thanks for the helpful hint. I had just run into this with the current
RC of wxFormBuilder 3.0.

Setting the subclass value to any valid text solves the error message.
