#228 Params of Custom Widget breaks XRC export

[Henning Hraban Ramm]

I guess wxGlade should convert those dollar params into something else during XRC export? Python export works.

Partially, this was also reported as part of bug #224.
I need to check that one about the 'malformed argument'. It might just have been introduced by loading a file with empty parameter list into 0.8.0. The $parent and $id probably should not be converted on export as they are intrinsic to wx.
The other one is due to code being entered on the "Code" property page.
Honestly, I'm not sure whether Custom Widgets, arguments or code make any sense at all for XRC export. How do you use the exported XRC?
It would probably be the best to ignore the extra code completely on XRC export. The new fields for "Code to be inserted before / after" are ignored anyway.

[Henning Hraban Ramm]

I hoped I could load my complete GUI via XRC, maybe using XRCed besides wxGlade. Since XRCed doesn’t work on my system anyway I resolved to "designing" my GUI in wxGlade, exporting to Python and copying to my actual GUI module what I need. (I was used to creating my GUI in code anyway.)

[Dietmar Schwertberger]

I would suggest to continue generating Python code. XRC is probably too limited.
Did you go through http://wxglade.sourceforge.net/docs/source_code.html ?
Especially when you look at the Wing IDE debugger screenshot at the bottom of the page, you will see that it's much nicer to use Python directly.
Usually, copy & paste should not be necessary if you follow the documentation, except for the first time when copying the empty handlers:
http://wxglade.sourceforge.net/docs/source_code.html#example-2-import-and-override
http://wxglade.sourceforge.net/docs/custom_widgets.html
With the new properties "Code to be inserted before / after" you should be able to achieve everything you need. If not, post on the mailing list as then probably something is missing from wxGlade.

Fixes for bug 224 are in 0.8.0a13, which is online now.
