Обсуждение: Mac Language and _()

I've isolated the pgAdmin3 crash on Mac:

listViews->AddPage(properties, _("Properties"));        //
NBP_PROPERTIES

This fails, but this:

listViews->AddPage(properties, wxT("Properties"));        //
NBP_PROPERTIES

succeeds, so clearly there is something amiss with the
unicode/translation stuff.  It probably has something to do with the
fact that pgAdmin3 thinks I'm Chinese.  I'm not sure what to do
next...any ideas?

Maybe your mac detects the missing the slant eyes :-)

First you can remove language files, in that case it should fall back to
english.

Still, in any case a wrong/missing translation may not result in an
invalid string, apparently that's what's happening.

It might be quite hard to locate this with pgadmin sources. AFAIR
there's a locale sample in wx, can you try that?

Good for the start, so this is a separated issue. This is hopefully
reproducable using a wx sample.

That's because the event is registered on wxID_CANCEL, which is not the
same as XRCID("wxID_CANCEL") although it should be.

Please set a breakpoint at contrib/src/xrc/xmlres.cpp line 1218 or so.
This is XRCID_Lookup, which retrieves an id from a string. It's called
from c++ runtime initialization code, to set all that
EVT_xxx(XRCID("...") ) stuff. Apparently, there's some other source
calling this, because there's no occurrence of XRCID("wxID_CANCEL") in
pgadmin's sources.
This initializer code is called before some other code is executed,
which assigns those well-known id values to the id strings (this is done
in xmlres.cpp AddStdXRCID_Records). If this code is not called prior to
requesting an XRCID for a well-known id string, a new id is generated
(which we don't like for wxID***) and the assert mentioned will rise.

With that breakpoint set, you'll get >300 calls, which is too much to
trace. You can remove all EVT_*** in any ui/*.cpp between
BEGIN_EVENT_TABLE and END_EVENT_TABLE; after that, there should be no
more call to to XRCID_Lookup before AddStdXRCID_Records(). Apparently on
Mac there *is* an illegal call, you'll catch it hopefully like this.

Obviously wxNotebook is f***ed up on mac. Could you please test this on
a wx sample?

Sorry it's taken so long to get back to you on this.  The "internat"
wxWidgets sample works correctly on my Mac.  When I run it, I get the
language selection dialog, then I get French, English, German, etc.
menus depending on which language I select.  Looks like I'm probably
doing something wrong when I build pgAdmin3.
