The following customization tips pertain to the CBasePane Class and any classes that inherit from it:When you create a pane, you can apply several new styles: AFX_CBRS_FLOAT makes the pane float. AFX_CBRS_AUTOHIDE enables auto-hide mode. AFX_CBRS_CLOSE enables the pane to be closed (...
Here is a simple example of a POINT structure, which contains two integers named x and y, and also shows how to initialize a structure in the constructor: from ctypes import * class POINT(Structure): ...fields= [("x", c_int), ...
Warn when a function declaration hides virtual functions from a base class. For example, in the following example, the A class version of f() is hidden in B. struct A { virtual void f();};struct B: public A { void f(int);}; As a result, the following code will fail to compile...
All the developer has to do is to write the SUPPORT_THREAD_SYNCHRONIZATION(ClassName) macro in the constructor in his CThread-Derived ClassName class where the thread-task handler (the virtual ThreadHandler() method) is actually implemented. Thread-Handler-Oriented Synchronization is supported for ...
