	25	Some time ago, I asked about how to right-align
	26	wxTextCtrls. Answer was that it is not supported. I forgot it.
	27
	28	Just a week ago, one of my clients asked me to have numbers right
	29	aligned. (Indeed it was that numbers MUST be right aligned).
	30
	31	So the game begun. Hacking, hacking, ...
	32
	33	At last, i succeed. Here is some code that someone may find
	34	useful. ubRightTextCtrl is right-aligned when you are not editing, but
	35	left-aligned if it has focus.
	36
	37	Hope this can help someone, as much as this list helps me.

	43	P.S. This only works well on wxMSW.
