+\func{bool}{GetStyle}{\param{long }{position}, \param{wxTextAttrEx\& }{style}}
+
+Gets the attributes at the given position.
+
+This function gets the combined style - that is, the style you see on the screen as a result
+of combining base style, paragraph style and character style attributes. To get the character
+or paragraph style alone, use \helpref{GetUncombinedStyle}{wxrichtextbuffergetuncombinedstyle}.

+\membersection{wxRichTextBuffer::GetStyleForRange}\label{wxrichtextbuffergetstyleforrange}

+\func{bool}{GetStyleForRange}{\param{const wxRichTextRange\&}{ range}, \param{wxTextAttrEx\& }{style}}
+
+This function gets a style representing the common, combined attributes in the given range.
+Attributes which have different values within the specified range will not be included the style
+flags.
+
+The function is used to get the attributes to display in the formatting dialog: the user
+can edit the attributes common to the selection, and optionally specify the values of further
+attributes to be applied uniformly.
+
+To apply the edited attributes, you can use \helpref{SetStyle}{wxrichtextbuffersetstyle} specifying
+the wxRICHTEXT\_SETSTYLE\_OPTIMIZE flag, which will only apply attributes that are different
+from the {\it combined} attributes within the range. So, the user edits the effective, displayed attributes
+for the range, but his choice won't be applied unnecessarily to content. As an example,
+say the style for a paragraph specifies bold, but the paragraph text doesn't specify a weight. The
+combined style is bold, and this is what the user will see on-screen and in the formatting
+dialog. The user now specifies red text, in addition to bold. When applying with
+SetStyle, the content font weight attributes won't be changed to bold because this is already specified
+by the paragraph. However the text colour attributes {\it will} be changed to
+show red.
