any idea why the documentation says this? cause this was the source of all my confusion... Reference counting can be implemented easily using wxObject and wxObjectRefData classes. First , derive a new class from wxObjectRefData and put there the memory-consuming data. Then derive a new class from wx...

I'm trying to derive my own reference counted class, but i'm finding the overview provided in the documentation a little sketchy. i've tired looking at headers for some of the built-in wx classes that use it, but they're all loaded up with extra stuff that makes it difficult for me to follow. So pre...

the Notify method in the base class is virtual, but there's no necessity for the inherting method to make Notify virtual.

Anyway, as I mentioned previously, diagnostics confirm that the Notify method is executing... it's just that the wxMessageDialog box is not going away.

well i guess the problem must be with wxMessageDialog, and perhaps more precisely with the ShowModal() method.

As you suggested I tried deriving only one class and the other class as a member for both instances and neither worked. oh well... i guess another approach is needed.

Simply wanted to create an instance of wxMessageDialog that if a button has not been clicked within a set period of time the message dialog would disappear... so i created the following: class c_timedMessageDialog : public wxMessageDialog, public wxTimer { public: c_timedMessageDialog( wxWindow* par...

There's an even cooler fix I found when searching on the internet... and that is to simply chain the typecasts from wxObjectEventFunction through to the most recently derived level. e.g. i have a custom derived event class called myEvent and so i would rewrite the connect call as: Connect( wxID_ANY,...

In my application in wxMAC and wxGTK, in response to a wxSOCKET_INPUT event, I perform two reads. The first reads 2 bytes from a packet that it has been sent, which (according to design) says how bytes there are in the entire packet. I then allot a buffer of this size and perform a 2nd read to fill ...

I have the following in my code: wxLogDebug( "%s%s%s", "test", __FILE__, __LINE__ ); anyone know why VC++8.0 won't stop complaning about... "unhandled exception at .... Access violation reading location ...." this has driven me crazy. i'm no longer sane or rational. Any...

Well I've managed to figure it out... originally my code was of the form: class sktClass : public wxEvtHandler, public classOne, public classTwo { public: void sktEvtHandler( wxSocketEvent& event ); void funcWhereIcallConnect(); }; and the VC8 compiler objected to my line of code: Connect( wxID_...

Platform: xcode 2.4.1 wxWidgets 2.8.0

used supplied .xcodeproj file to succesfully compile wxWidgets 2.8.0

used supplied .xcodeproj file to compile minimal application, which returned the following errors:

Building target

I tried that, and the compiler returns the following error:

..\skt.cpp(45) : error C2440: 'type cast' : cannot convert from 'overloaded-function' to 'wxObjectEventFunction'
None of the functions with this name in scope match the target type

PLATFORM: Windows XP, VC 8.0, wxWidgets 2.8 I have this line in my application: Connect( wxID_ANY, wxEVT_SOCKET, (wxObjectEventFunction)&c_skt::onSocketEvent); the compiler gives this error: z:\r0.5\skt.cpp(45) : error C2440: 'type cast' : cannot convert from 'void (__thiscall c_skt::* )(wxSocke...

Try this: void methodToWriteToTextControl( wxString displayString ) { wxString str; int index; textCtrlPtr->SetInsertionPointEnd(); for( index = 0; index < displayString.Len(); ++index ) { str = displayString.Mid( index, 1 ); textCtrlPtr->WriteText( str ); } textCtrlPtr->ShowPosition( textStrlPtr->G...

I'm running 2.8 on an intel Mac and the ::wxYield() did nothing for me.... however, this DID work... and it works on wxGTK too, i'd be interested in knowing if it works on wxMSW as well. void methodToWriteToTextControl( wxString displayString ) { wxString str; int index; textCtrlPtr->SetInsertionPoi...

Yes, that's basically right. You limit the kind of events that are generated with the SetNotify() method. e.g. if you only want to respond to connection lost and socket input you would write: socket->SetNotify( wxSOCKET_INPUT_FLAG | wxSOCKET_LOST_FLAG ); given that in the above example you've specif...
