/**
@class wxRichTextStyleListCtrl
This class incorporates a wxRichTextStyleListBox and a choice control that
allows the user to select the category of style to view.
It is demonstrated in the wxRichTextCtrl sample in @c samples/richtext.
To use wxRichTextStyleListCtrl, add the control to your window hierarchy and
call wxRichTextStyleListCtrl::SetStyleType with one of
wxRichTextStyleListBox::wxRICHTEXT_STYLE_ALL,
wxRichTextStyleListBox::wxRICHTEXT_STYLE_PARAGRAPH,
wxRichTextStyleListBox::wxRICHTEXT_STYLE_CHARACTER and
wxRichTextStyleListBox::wxRICHTEXT_STYLE_LIST to set the current view.
Associate the control with a style sheet and rich text control with
SetStyleSheet and SetRichTextCtrl, so that when a style is double-clicked,
it is applied to the selection.
@beginStyleTable
@style{wxRICHTEXTSTYLELIST_HIDE_TYPE_SELECTOR}
This style hides the category selection control.
@endStyleTable
@library{wxrichtext}
@category{richtext}
