The code is fairly straightforward, except perhaps for the call to convertColumnIndexToModel. That call is necessary because if the user moves the columns around, the view s index for the column doesn t match the model s index for the column. For example, the user might drag the Vegetarian column (which the model considers to be at index 4) so it s displayed as the first column — at view index 0. Since prepareRenderer gives us the view index, we need to translate the view index to a model index so we can be sure we re dealing with the intended column
This code detects memory leaks in embedded VC++ almost the same way crtdbg does in VC++. At the end of program execution it will display in the debug window if there were any memory leaks and how the memory looks so you can identify where your memory leak occurred. It will display in the debug window a message saying no memory leaks detected if there are no memory leaks. Similar to what crtdbg.h does in VC++. The code detects memory leaks generated with calls to new and delete operators in C++. The code doesn t detect memory leaks generated with C functions: malloc, calloc, free, but that can be done in the future. Let me know and I will program it.
