\membersection{wxRichTextBuffer::GetBasicStyle}\label{wxrichtextbuffergetbasicstyle}

\constfunc{const wxTextAttrEx\&}{GetBasicStyle}{\void}

Gets 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::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
