You cannot create +an instance of an abstract class directly - you need to subclass +it. In the subclass, you need to overload <i>all</i> of the +class's <a href="#purevirtual">pure virtual</a> methods. These +are marked as "pure virtual" in these docs, and are also indicated +by a " = 0" at the end of the method declaration. +</p> +<p> +If your subclass doesn't overload the pure virtual methods in the +abstract base class, you won't be able to create an instance of it. +</p> + +<h2><a name="purevirtual">pure virtual</a></h2> +<p> +Pure virtual methods are members of an <a href="#abstract">abstract</a> +class (they're what makes the class abstract in the first place). Pure +virtual methods are nothing more than place holders - there is no code +associated with them +</p> + + +<h2><a name="variables">variables</a></h2> +<p> +Class variables can be read and written from Python. Global or static +variables are <i>read only</i>. Variables that are "protected" or. +"private" in C++ are not implemented. +</p> + +<h2><a name="slots">slots</a></h2> +<p> +When using Qt or KDE in C++, methods involving connections to slots +take 2 arguments: a QObject 'receiver' and a char* 'slot' name. In Python +you only need to provide a single value - the name of a Python callable +method or function which will be connected to a signal. The method or +function does not need to be in the class where it is reference, and does +not have to be in a class at all. There are other options - see the +"Signals and Slots" documentation for more information. +</p> |
