hello!
XRCed stores growablecols and growablerows parameters for wxFlexGridSizer and wxGridBagSizer as a list of nodes, like this:
<object class="wxGridBagSizer">
<growablecols>0</growablecols>
<growablecols>2</growablecols>
</object>
but xrc loader requires these parameters to be a comma-separated list of numbers, like this:
<object class="wxGridBagSizer">
<growablecols>0, 2</growablecols>
</object>
to work around this, i have added 'growablecols' and 'growablerows' to the 'allParams' lists for classes xxxFlexGridSizer and xxxGridBagSizer in XRCed/xxx.py, and disabled 'specials' and 'paramDict' definitions in these classes. there definitely is a better solution...
best wishes,
alex.
