February 17, 2004 wx 2.4.2 - which version to get | ||||
---|---|---|---|---|
| ||||
I see from this list (and have experienced) some problems with 2.4.2 downloaded as installer. Would you recommend that I use CVS instead? - I don't really want to be at the bleeding edge of wxWin development though. I.e. should I go for a particulary CVS branch? OR would you recommend that I patch the standard 2.4.2 according to bugfixes posted on this list? thanks Eliot |

Posted in reply to eliot | You are also able to retrieve the 2.4.2 from the CVS. (Called a 'branch' named WX_2_4_BRANCH)
I would suggest you try this first.

OK, I have done that and the libraries compile OK.
The minimal sample compiles OK, but the controls sample crashes (access violation I think).
(Compiler version 8.38n, Windows XP)
I guess I'd better figure out how to run the debugger on an application built using a makefile...
My CD arrived in the mail a couple of days ago - do I need to upgrade the compiler as well?

Yes a access violation because the wxWindows holds a const reference to a temporary object and uses the reference after the object gets destroyed. Change line 360 in src/msw/tooltip.cpp like below: ----------------------------<snip>----------------------------------------- #if !defined(__WXUNIVERSAL__) // and all of its subcontrols (e.g. radiobuttons in a radiobox) as well wxControl *control = wxDynamicCast(m_window, wxControl); if ( control ) { // const wxArrayLong& subcontrols = control->GetSubcontrols(); const wxArrayLong subcontrols = control->GetSubcontrols(); size_t count = subcontrols.GetCount(); for ( size_t n = 0; n < count; n++ ) { int id = subcontrols[n]; ----------------------------<snip>----------------------------------------- A few days ago Matthew Wilson reported the same kind of problem which seems to be supposed to work this way. Arjan. |

Posted in reply to Arjan Knepper | I've just been alerted to this on wx-dev and have made this change in wxWindows 2.4 and 2.5 CVS. Thanks!

Thanks! That solved it.
Now I'm going to start a new thread with my question about debugging..
