\membersection { wxRichTextBuffer::AddEventHandler} \label { wxrichtextbufferaddeventhandler}
\func { bool} { AddEventHandler} { \param { wxEvtHandler* } { handler} }
Adds an event handler to the buffer's list of handlers. A buffer associated with
a contol has the control as the only event handler, but the application is free
to add more if further notification is required. All handlers are notified
of an event originating from the buffer, such as the replacement of a style sheet
during loading. The buffer never deletes any of the event handlers, unless
\helpref { wxRichTextBuffer::RemoveEventHandler} { wxrichtextbufferremoveeventhandler} is
called with \true as the second argument.

Adds a file handler.
\membersection { wxRichTextBuffer::AddParagraph} \label { wxrichtextbufferaddparagraph}
\func { wxRichTextRange} { AddParagraph} { \param { const wxString\& } { text} }
Adds a paragraph of text.
\membersection { wxRichTextBuffer::BatchingUndo} \label { wxrichtextbufferbatchingundo}
\constfunc { bool} { BatchingUndo} { \void }
Returns \true if the buffer is currently collapsing commands into a single notional command.
\membersection { wxRichTextBuffer::BeginAlignment} \label { wxrichtextbufferbeginalignment}
\func { bool} { BeginAlignment} { \param { wxTextAttrAlignment } { alignment} }
Begins using alignment.
\membersection { wxRichTextBuffer::BeginBatchUndo} \label { wxrichtextbufferbeginbatchundo}
\func { bool} { BeginBatchUndo} { \param { const wxString\& } { cmdName} }
Begins collapsing undo/redo commands. Note that this may not work properly
if combining commands that delete or insert content, changing ranges for
subsequent actions.
{ \it cmdName} should be the name of the combined command that will appear
next to Undo and Redo in the edit menu.
\membersection { wxRichTextBuffer::BeginBold} \label { wxrichtextbufferbeginbold}
\func { bool} { BeginBold} { \void }
Begin applying bold.
\membersection { wxRichTextBuffer::BeginCharacterStyle} \label { wxrichtextbufferbegincharacterstyle}

Begin using { \it leftIndent} for the left indent, and optionally { \it leftSubIndent} for
the sub-indent. Both are expressed in tenths of a millimetre.
The sub-indent is an offset from the left of the paragraph, and is used for all but the
first line in a paragraph. A positive value will cause the first line to appear to the left
of the subsequent lines, and a negative value will cause the first line to be indented
relative to the subsequent lines.
\membersection { wxRichTextBuffer::BeginLineSpacing} \label { wxrichtextbufferbeginlinespacing}
\func { bool} { BeginLineSpacing} { \param { int } { lineSpacing} }
Begins line spacing using the specified value. { \it spacing} is a multiple, where 10 means single-spacing,
15 means 1.5 spacing, and 20 means double spacing. The following constants are
defined for convenience:
{ \small
\begin { verbatim}
#define wxTEXT_ ATTR_ LINE_ SPACING_ NORMAL 10
#define wxTEXT_ ATTR_ LINE_ SPACING_ HALF 15
#define wxTEXT_ ATTR_ LINE_ SPACING_ TWICE 20

application should take care of incrementing the numbering.
{ \it bulletNumber} is a number, usually starting with 1.
{ \it leftIndent} and { \it leftSubIndent} are values in tenths of a millimetre.
{ \it bulletStyle} is a bitlist of the following values:
{ \small
\begin { verbatim}

\end { verbatim}
}
wxRichTextBuffer uses indentation to render a bulleted item. The left indent is the distance between
the margin and the bullet. The content of the paragraph, including the first line, starts
at leftMargin + leftSubIndent. So the distance between the left edge of the bullet and the
left of the actual paragraph is leftSubIndent.
\membersection { wxRichTextBuffer::BeginParagraphSpacing} \label { wxrichtextbufferbeginparagraphspacing}
\func { bool} { BeginParagraphSpacing} { \param { int } { before} , \param { int } { after} }
Begins paragraph spacing; pass the before-paragraph and after-paragraph spacing in tenths of
a millimetre.

\membersection { wxRichTextBuffer::BeginStyle} \label { wxrichtextbufferbeginstyle}
\func { bool} { BeginStyle} { \param { const wxTextAttrEx\& } { style} }
Begins using a specified style.
\membersection { wxRichTextBuffer::BeginSuppressUndo} \label { wxrichtextbufferbeginsuppressundo}
\func { bool} { BeginSuppressUndo} { \void }
Begins suppressing undo/redo commands. The way undo is suppressed may be implemented
differently by each command. If not dealt with by a command implementation, then
it will be implemented automatically by not storing the command in the undo history
when the action is submitted to the command processor.
2006-10-26 06:32:47 +00:00
\membersection { wxRichTextBuffer::BeginStandardBullet} \label { wxrichtextbufferbeginstandardbullet}

style to bold will cause subsequently inserted text to be bold).
2006-07-01 20:30:58 +00:00
\membersection { wxRichTextBuffer::GetExtWildcard} \label { wxrichtextbuffergetextwildcard}
\func { wxString} { GetExtWildcard} { \param { bool } { combine = false} , \param { bool } { save = false} , \param { wxArrayInt* } { types = NULL} }
Gets a wildcard incorporating all visible handlers. If { \it types} is present,
it will be filled with the file type corresponding to each filter. This can be
used to determine the type to pass to \helpref { LoadFile} { wxrichtextbuffergetextwildcard} given a selected filter.
\membersection { wxRichTextBuffer::GetHandlers} \label { wxrichtextbuffergethandlers}
\func { wxList\& } { GetHandlers} { \void }
Returns the list of file handlers.

\membersection { wxRichTextBuffer::GetRenderer} \label { wxrichtextbuffergetrenderer}
\func { static wxRichTextRenderer*} { GetRenderer} { \void }
Returns the object to be used to render certain aspects of the content, such as bullets.
2006-10-10 16:48:47 +00:00
\membersection { wxRichTextBuffer::GetStyle} \label { wxrichtextbuffergetstyle}
\func { bool} { GetStyle} { \param { long } { position} , \param { wxRichTextAttr\& } { style} }
\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.
2006-07-01 20:30:58 +00:00
\membersection { wxRichTextBuffer::GetStyleSheet} \label { wxrichtextbuffergetstylesheet}
\constfunc { wxRichTextStyleSheet*} { GetStyleSheet} { \void }
Returns the current style sheet associated with the buffer, if any.
\membersection { wxRichTextBuffer::GetStyleStackSize} \label { wxrichtextbuffergetstylestacksize}
\constfunc { size\_ t} { GetStyleStackSize} { \void }
Get the size of the style stack, for example to check correct nesting.
2006-10-10 16:48:47 +00:00
\membersection { wxRichTextBuffer::GetUncombinedStyle} \label { wxrichtextbuffergetuncombinedstyle}
\func { bool} { GetUncombinedStyle} { \param { long } { position} , \param { wxRichTextAttr\& } { style} }
\func { bool} { GetUncombinedStyle} { \param { long } { position} , \param { wxTextAttrEx\& } { style} }
Gets the attributes at the given position.
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} { wxrichtextbuffergetstyle} .
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.
2006-07-01 20:30:58 +00:00
\membersection { wxRichTextBuffer::HitTest} \label { wxrichtextbufferhittest}
\func { int} { HitTest} { \param { wxDC\& } { dc} , \param { const wxPoint\& } { pt} , \param { long\& } { textPosition} }
Finds the text position for the given position, putting the position in { \it textPosition} if
one is found. { \it pt} is in logical units (a zero y position is
at the beginning of the buffer).
The function returns one of the following values:
{ \small
\begin { verbatim}
// The point was not on this object
#define wxRICHTEXT_ HITTEST_ NONE 0x01
// The point was before the position returned from HitTest
#define wxRICHTEXT_ HITTEST_ BEFORE 0x02
// The point was after the position returned from HitTest
#define wxRICHTEXT_ HITTEST_ AFTER 0x04
// The point was on the position returned from HitTest
#define wxRICHTEXT_ HITTEST_ ON 0x08
\end { verbatim}

is initialised by default.
\membersection { wxRichTextBuffer::InsertHandler} \label { wxrichtextbufferinserthandler}
\func { void} { InsertHandler} { \param { wxRichTextFileHandler* } { handler} }
Inserts a handler at the front of the list.
\membersection { wxRichTextBuffer::InsertImageWithUndo} \label { wxrichtextbufferinsertimagewithundo}
\func { bool} { InsertImageWithUndo} { \param { long } { pos} , \param { const wxRichTextImageBlock\& } { imageBlock} , \param { wxRichTextCtrl* } { ctrl} }

\func { void} { SetBasicStyle} { \param { const wxRichTextAttr\& } { style} }
\func { void} { SetBasicStyle} { \param { const wxTextAttrEx\& } { style} }
Sets the basic (overall) style. This is the style of the whole
buffer before further styles are applied, unlike the default style, which
only affects the style currently being applied (for example, setting the default
style to bold will cause subsequently inserted text to be bold).
\membersection { wxRichTextBuffer::SetDefaultStyle} \label { wxrichtextbuffersetdefaultstyle}
\func { void} { SetDefaultStyle} { \param { const wxTextAttrEx\& } { style} }
Sets the default style, affecting the style currently being applied (for example, setting the default
style to bold will cause subsequently inserted text to be bold).
This is not cumulative - setting the default style will replace the previous default style.

2006-10-28 10:49:30 +00:00
Sets the attributes for the given range. Pass flags to determine how the attributes are set.
2006-10-10 16:48:47 +00:00
The end point of range is specified as the last character position of the span of text.
So, for example, to set the style for a character at position 5, use the range (5,5).
This differs from the wxRichTextCtrl API, where you would specify (5,6).
{ \it flags} may contain a bit list of the following values:
2006-10-28 10:49:30 +00:00
\begin { itemize} \itemsep =0pt
\item wxRICHTEXT\_ SETSTYLE\_ NONE: no style flag.
\item wxRICHTEXT\_ SETSTYLE\_ WITH\_ UNDO: specifies that this operation should be undoable.
\item wxRICHTEXT\_ SETSTYLE\_ OPTIMIZE: specifies that the style should not be applied if the
combined style at this point is already the style in question.
2006-11-17 08:33:34 +00:00
\item wxRICHTEXT\_ SETSTYLE\_ PARAGRAPHS\_ ONLY: specifies that the style should only be applied to paragraphs,
2006-10-28 10:49:30 +00:00
and not the content. This allows content styling to be preserved independently from that of e.g. a named paragraph style.
\item wxRICHTEXT\_ SETSTYLE\_ CHARACTERS\_ ONLY: specifies that the style should only be applied to characters,
and not the paragraph. This allows content styling to be preserved independently from that of e.g. a named paragraph style.
2006-11-17 08:33:34 +00:00
\item wxRICHTEXT\_ SETSTYLE\_ RESET: resets (clears) the existing style before applying the new style.
