You didn't tell the object at all what it is, and now you try to use it. The guess here is that you want to have a new local instance of a Arts::Synth_PLAY object. Of course you might have wanted something else (like creating the object somewhere else, or using an existing remote object). However, it is a convenient short cut to creating objects. Lazy creation will not work once you assigned something else (like a null reference). </para> <para> The equivalent C++ terms would be <programlisting> - QWidget* w; + TQWidget* w; w->show(); </programlisting> which obviously in C++ just plain segfaults. So this is different here. This lazy creation is tricky especially as not necessarily an implementation exists for your interface. </para> <para> For instance, consider an abstract thing like a Arts::PlayObject. There are certainly concrete PlayObjects like those for playing mp3s or wavs, but <programlisting> Arts::PlayObject po; |
