+In general wxWindow-derived objects should always be allocated on the heap
+as wxWidgets will destroy them itself. The only, but important, exception to
+this rule are the modal dialogs, i.e. wxDialog objects which are shown using
+wxDialog::ShowModal() method. They may be allocated on the stack and, indeed,
+usually are local variables to ensure that they are destroyed on scope exit as
+wxWidgets does not destroy them unlike with all the other windows. So while it
+is still possible to allocate modal dialogs on the heap, you should still
+destroy or delete them explicitly in this case instead of relying on wxWidgets
+doing it.

 wxColour can be created statically: it is not automatically cleaned
 up and is unlikely to be shared between other objects; it is lightweight
 enough for copies to be made.

-You can reduce the possibility of memory leaks substantially, and it is much more
-convenient to use the overloaded operators than functions such as @c strcmp.
-wxString won't add a significant overhead to your program; the overhead is compensated
-for by easier manipulation (which means less code).

 The same goes for other data types: use classes wherever possible.

-It is common to blow up the problem in one's imagination, so that it seems to threaten
-weeks, months or even years of work. The problem you face may seem insurmountable:
-but almost never is. Once you have been programming for some time, you will be able
-to remember similar incidents that threw you into the depths of despair. But
-remember, you always solved the problem, somehow!

-Perseverance is often the key, even though a seemingly trivial problem
-can take an apparently inordinate amount of time to solve. In the end,
-you will probably wonder why you worried so much. That's not to say it
-isn't painful at the time. Try not to worry -- there are many more important
-things in life.

-With luck, you can add a small amount of code that causes the program
-to go from functioning to non-functioning state. This should give a clue

-deallocation, this can still give totally spurious results!
