\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.
|
|
|
|
\membersection{wxRichTextBuffer::AddHandler}\label{wxrichtextbufferaddhandler}

|
|
|
|
\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.
|
|
|

|
|
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.

|
|
15 means 1.5 spacing, and 20 means double spacing. The following constants are
|
|
defined for convenience:
|
|
|
|

|
|
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.
|
|
|

|
|
it will be implemented automatically by not storing the command in the undo history
|
|
when the action is submitted to the command processor.
|
|
|
|
\membersection{wxRichTextBuffer::BeginStandardBullet}\label{wxrichtextbufferbeginstandardbullet}

\membersection{wxRichTextBuffer::GetCommandProcessor}\label{wxrichtextbuffergetcommandprocessor}
|
|
|
|
\constfunc{wxCommandProcessor*}{GetCommandProcessor}{\void}
|
|
|
|
Gets the command processor. A text buffer always creates its own command processor when it is
|
|
initialized.
|
|
|
|
\membersection{wxRichTextBuffer::GetDefaultStyle}\label{wxrichtextbuffergetdefaultstyle}
|
|
|
|
\constfunc{const wxTextAttrEx\&}{GetDefaultStyle}{\void}
|
|
|
|
Returns the current default style, affecting the style currently being applied (for example, setting the default
|
|
style to bold will cause subsequently inserted text to be bold).
|
|
|
|
\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.
|
|
|
|
\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.
|
|
|
|
\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.
|
|
|
|
\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.
|
|
|
|
\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

|
|
#define wxRICHTEXT_HITTEST_BEFORE 0x02
|

|
|
|
|
\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).

|
|
|
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.

|
|
Either the style definition or the name of the style definition (in the current sheet) can be passed.
|
|
|
|
{\it flags} is a bit list of the following:

\func{static void}{SetRenderer}{\param{wxRichTextRenderer* }{renderer}}
|
|
|
|
Sets {\it renderer} as the object to be used to render certain aspects of the content, such as bullets.
|
|
You can override default rendering by deriving a new class from wxRichTextRenderer or wxRichTextStdRenderer,
|
|
overriding one or more virtual functions, and setting an instance of the class using this function.

\func{bool}{SetStyle}{\param{const wxRichTextRange\& }{range}, \param{const wxTextAttrEx\& }{style}, \param{int }{flags $=$ wxRICHTEXT\_SETSTYLE\_WITH\_UNDO}}
|
|
|
|
Sets the attributes for the given range. Pass flags to determine how the attributes are set.
|
|
|
|
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:
|
|
|
|
\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.
|
|
\item wxRICHTEXT\_SETSTYLE\_PARAGRAPHS\_ONLY: specifies that the style should only be applied to paragraphs,
|
|
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.
|
|
\item wxRICHTEXT\_SETSTYLE\_RESET: resets (clears) the existing style before applying the new style.
|
|
\item wxRICHTEXT\_SETSTYLE\_REMOVE: removes the specified style. Only the style flags are used in this operation.
|
|
