3 wxRichTextCtrl provides a generic, ground-up implementation of a text control
4 capable of showing multiple styles and images.
5
6 wxRichTextCtrl sends notification events: see \helpref{wxRichTextEvent}{wxrichtextevent}.
7 It also sends the standard wxTextCtrl events wxEVT\_COMMAND\_TEXT\_ENTER and wxEVT\_COMMAND\_TEXT\_UPDATED,
8 and wxTextUrlEvent when URL content is clicked.

152 Begins using italic.
153
154 \membersection{wxRichTextCtrl::BeginLeftIndent}\label{wxrichtextctrlbeginleftindent}
155
156 \func{bool}{BeginLeftIndent}{\param{int }{leftIndent}, \param{int }{leftSubIndent = 0}}
157
158 Begins applying a left indent and subindent in tenths of a millimetre.
159
160 The sub-indent is an offset from the left of the paragraph, and is used for all but the
161 first line in a paragraph. A positive value will cause the first line to appear to the left
162 of the subsequent lines, and a negative value will cause the first line to be indented
163 relative to the subsequent lines.
164
165 wxRichTextBuffer uses indentation to render a bulleted item. The left indent is the distance between
166 the margin and the bullet. The content of the paragraph, including the first line, starts
167 at leftMargin + leftSubIndent. So the distance between the left edge of the bullet and the
168 left of the actual paragraph is leftSubIndent.
169
170 \membersection{wxRichTextCtrl::BeginLineSpacing}\label{wxrichtextctrlbeginlinespacing}

195
196 Begins a numbered bullet. This call will be needed for each item in the list, and the
197 application should take care of incrementing the numbering.
198
199 {\it bulletNumber} is a number, usually starting with 1.
200
201 {\it leftIndent} and {\it leftSubIndent} are values in tenths of a millimetre.
202
203 {\it bulletStyle} is a bitlist of the following values:
204
205 {\small

223 \end{verbatim}
224 }
225
226 wxRichTextBuffer uses indentation to render a bulleted item. The left indent is the distance between
227 the margin and the bullet. The content of the paragraph, including the first line, starts
228 at leftMargin + leftSubIndent. So the distance between the left edge of the bullet and the
229 left of the actual paragraph is leftSubIndent.

698
699 \func{bool}{GetStyle}{\param{long }{position}, \param{wxTextAttr\& }{style}}
700
701 Gets the attributes at the given position. The wxRichTextAttr version is generally more efficient
702 because it does not use wxFont objects.
703
704 This function gets the combined style - that is, the style you see on the screen as a result
705 of combining base style, paragraph style and character style attributes. To get the character
706 or paragraph style alone, use \helpref{GetUncombinedStyle}{wxrichtextctrlgetuncombinedstyle}.
707
708 \membersection{wxRichTextCtrl::GetStyleForRange}\label{wxrichtextctrlgetstyleforrange}
709
710 \func{bool}{GetStyleForRange}{\param{const wxRichTextRange\& }{range}, \param{wxRichTextAttr\& }{style}}
711
712 \func{bool}{GetStyleForRange}{\param{const wxRichTextRange\& }{range}, \param{wxTextAttrEx\& }{style}}

715 not be included in {\it style}'s flags.
716
717 \membersection{wxRichTextCtrl::GetStyleSheet}\label{wxrichtextctrlgetstylesheet}
718
719 \constfunc{wxRichTextStyleSheet*}{GetStyleSheet}{\void}
720
721 Returns the style sheet associated with the control, if any. A style sheet allows named
722 character and paragraph styles to be applied.
723
724 \membersection{wxRichTextCtrl::GetUncombinedStyle}\label{wxrichtextctrlgetuncombinedstyle}
725
726 \func{bool}{GetUncombinedStyle}{\param{long }{position}, \param{wxRichTextAttr\& }{style}}

729
730 \func{bool}{GetUncombinedStyle}{\param{long }{position}, \param{wxTextAttr\& }{style}}
731
732 Gets the attributes at the given position. The wxRichTextAttr version is generally more efficient
733 because it does not use wxFont objects.
734
735 This function gets the {\it uncombined style} - that is, the attributes associated with the
736 paragraph or character content, and not necessarily the combined attributes you see on the
737 screen. To get the combined attributes, use \helpref{GetStyle}{wxrichtextctrlgetstyle}.
738
739 If you specify (any) paragraph attribute in {\it style}'s flags, this function will fetch
740 the paragraph attributes. Otherwise, it will return the character attributes.
741

751
752 Internal helper function returning the line for the visible caret position. If the caret is
753 shown at the very end of the line, it means the next character is actually
754 on the following line. So this function gets the line we're expecting to find
755 if this is the case.
756
757 \membersection{wxRichTextCtrl::HasCharacterAttributes}\label{wxrichtextctrlhascharacterattributes}

808
809 \constfunc{bool}{IsDefaultStyleShowing}{\void}
810
811 Returns \true if the user has recently set the default style without moving the caret,
812 and therefore the UI needs to reflect the default style and not the style at the caret.
813
814 Below is an example of code that uses this function to determine whether the UI
815 should show that the current style is bold.
816
817 \begin{verbatim}
