Implementing HTMLEditor example from wxdevcpp book.
splitter window edit property vertical - runtime
splitter window edit property horizontal - runtime
splitter window vertical.
In the GUI builder, the splitter window initially
displays as a horizontal split (contrary to the books
assertion - apparently it expects vertical.) And, the
properties in fact indicate the orientation is horizontal.
Compile and run the program, the executing program
displays the splitter as a vertical split.
Go change orientation to vertical (no auto-refresh -
have to click somewhere [splitter?] in builder to get
refresh). Recompile program and run, running program
displays splitter window as horizontal.
