\constfunc{void}{GetSelection}{\param{long* }{from}, \param{long* }{to}}

Returns the range of the current selection.

\membersection{wxRichTextCtrl::GetStyle}\label{wxrichtextctrlgetstyle}

\func{bool}{GetStyle}{\param{long }{position}, \param{wxRichTextAttr\& }{style}}

\func{bool}{GetStyle}{\param{long }{position}, \param{wxTextAttrEx\& }{style}}

\func{bool}{GetStyle}{\param{long }{position}, \param{wxTextAttr\& }{style}}

Gets the attributes at the given position. The wxRichTextAttr version is generally more efficient
because it does not use wxFont objects.

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}{wxrichtextctrlgetuncombinedstyle}.

\membersection{wxRichTextCtrl::GetStyleForRange}\label{wxrichtextctrlgetstyleforrange}

\func{bool}{GetStyleForRange}{\param{const wxRichTextRange\& }{range}, \param{wxRichTextAttr\& }{style}}

\func{bool}{GetStyleForRange}{\param{const wxRichTextRange\& }{range}, \param{wxTextAttrEx\& }{style}}

not be included in {\it style}'s flags.

\membersection{wxRichTextCtrl::GetStyleSheet}\label{wxrichtextctrlgetstylesheet}

\constfunc{wxRichTextStyleSheet*}{GetStyleSheet}{\void}

Returns the style sheet associated with the control, if any. A style sheet allows named
character and paragraph styles to be applied.

\membersection{wxRichTextCtrl::GetUncombinedStyle}\label{wxrichtextctrlgetuncombinedstyle}

\func{bool}{GetUncombinedStyle}{\param{long }{position}, \param{wxRichTextAttr\& }{style}}

\func{bool}{GetUncombinedStyle}{\param{long }{position}, \param{wxTextAttrEx\& }{style}}

\func{bool}{GetUncombinedStyle}{\param{long }{position}, \param{wxTextAttr\& }{style}}

Gets the attributes at the given position. The wxRichTextAttr version is generally more efficient
because it does not use wxFont objects.

This function gets the {\it uncombined style} - that is, the attributes associated with the
paragraph or character content, and not necessarily the combined attributes you see on the
screen. To get the combined attributes, use \helpref{GetStyle}{wxrichtextctrlgetstyle}.

If you specify (any) paragraph attribute in {\it style}'s flags, this function will fetch
the paragraph attributes. Otherwise, it will return the character attributes.

\membersection{wxRichTextCtrl::GetValue}\label{wxrichtextctrlgetvalue}

\constfunc{wxString}{GetValue}{\void}

Returns the content of the entire control as a string.

\membersection{wxRichTextCtrl::GetVisibleLineForCaretPosition}\label{wxrichtextctrlgetvisiblelineforcaretposition}
