## Member Function Documentation

static void wxRichTextBuffer::AddDrawingHandler | ( | wxRichTextDrawingHandler * | handler | ) |
| static

Adds a drawing handler to the end.

bool wxRichTextBuffer::AddEventHandler | ( | wxEvtHandler * | handler | ) |

Adds an event handler.

A buffer associated with a control 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 RemoveEventHandler() is called with true as the second argument.

static void wxRichTextBuffer::AddFieldType | ( | wxRichTextFieldType * | fieldType | ) |
| static

Adds a field type.

See Also
  RemoveFieldType(), FindFieldType(), wxRichTextField, wxRichTextFieldType, wxRichTextFieldTypeStandard

static void wxRichTextBuffer::AddHandler | ( | wxRichTextFileHandler * | handler | ) |
| static

Adds a file handler to the end.

virtual wxRichTextRange wxRichTextBuffer::AddParagraph | ( | const wxString & | text,
|  | wxRichTextAttr * | paraStyle = `NULL`
| ) |  |
| inline virtual

Convenience function to add a paragraph of text.

Reimplemented from wxRichTextParagraphLayoutBox.

virtual bool wxRichTextBuffer::BatchingUndo | ( |  | ) | const
| inline virtual

Returns true if we are collapsing commands.

bool wxRichTextBuffer::BeginAlignment | ( | wxTextAttrAlignment | alignment | ) |

Begins using alignment.

virtual bool wxRichTextBuffer::BeginBatchUndo | ( | const wxString & | cmdName | ) |
| virtual

Begin collapsing undo/redo commands.

Note that this may not work properly if combining commands that delete or insert content, changing ranges for subsequent actions.

cmdName should be the name of the combined command that will appear next to Undo and Redo in the edit menu.

bool wxRichTextBuffer::BeginBold | ( |  | ) |

Begins using bold.

bool wxRichTextBuffer::BeginCharacterStyle | ( | const wxString & | characterStyle | ) |

Begins named character style.

bool wxRichTextBuffer::BeginFont | ( | const wxFont & | font | ) |

Begins using this font.

bool wxRichTextBuffer::BeginFontSize | ( | int | pointSize | ) |

Begins using point size.

bool wxRichTextBuffer::BeginItalic | ( |  | ) |

Begins using italic.

bool wxRichTextBuffer::BeginLeftIndent | ( | int | leftIndent,
|  | int | leftSubIndent = `0`
| ) |  |

Begins using leftIndent for the left indent, and optionally 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.

bool wxRichTextBuffer::BeginLineSpacing | ( | int | lineSpacing | ) |

Begins line spacing using the specified value.

spacing is a multiple, where 10 means single-spacing, 15 means 1.5 spacing, and 20 means double spacing.

The wxTextAttrLineSpacing enumeration values are defined for convenience.

bool wxRichTextBuffer::BeginListStyle | ( | const wxString & | listStyle,
|  | int | level = `1`,
|  | int | number = `1`
| ) |  |

Begins named list style.

Optionally, you can also pass a level and a number.

bool wxRichTextBuffer::BeginNumberedBullet | ( | int | bulletNumber,
|  | int | leftIndent,
|  | int | leftSubIndent,
|  | int | bulletStyle = `wxTEXT_ATTR_BULLET_STYLE_ARABIC|wxTEXT_ATTR_BULLET_STYLE_PERIOD`
| ) |  |

Begins numbered bullet.

This call will be needed for each item in the list, and the application should take care of incrementing the numbering.

bulletNumber is a number, usually starting with 1. leftIndent and leftSubIndent are values in tenths of a millimetre. bulletStyle is a bitlist of the following values:

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.

bool wxRichTextBuffer::BeginParagraphSpacing | ( | int | before,
|  | int | after
| ) |  |

Begins paragraph spacing; pass the before-paragraph and after-paragraph spacing in tenths of a millimetre.

bool wxRichTextBuffer::BeginParagraphStyle | ( | const wxString & | paragraphStyle | ) |

|  | int | leftIndent,
|  | int | leftSubIndent,
|  | int | bulletStyle = `wxTEXT_ATTR_BULLET_STYLE_STANDARD`
| ) |  |

Begins applying a standard bullet, using one of the standard bullet names (currently `standard/circle` or `standard/square`.

See BeginNumberedBullet() for an explanation of how indentation is used to render the bulleted paragraph.

virtual bool wxRichTextBuffer::BeginStyle | ( | const wxRichTextAttr & | style | ) |
| virtual

Begin using a style.

virtual bool wxRichTextBuffer::BeginSuppressUndo | ( |  | ) |
| virtual

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.

bool wxRichTextBuffer::BeginSymbolBullet | ( | const wxString & | symbol,
|  | int | leftIndent,
|  | int | leftSubIndent,
|  | int | bulletStyle = `wxTEXT_ATTR_BULLET_STYLE_SYMBOL`
| ) |  |

Begins applying a symbol bullet, using a character from the current font.

See BeginNumberedBullet() for an explanation of how indentation is used to render the bulleted paragraph.

bool wxRichTextBuffer::BeginTextColour | ( | const wxColour & | colour | ) |

Begins using this colour.

bool wxRichTextBuffer::BeginUnderline | ( |  | ) |

Begins using underline.

bool wxRichTextBuffer::BeginURL | ( | const wxString & | url,
|  | const wxString & | characterStyle = `wxEmptyString`
| ) |  |

Pass false to speed up editing by not performing floating layout. This setting affects all buffers.

void wxRichTextBuffer::SetFontScale | ( | double | fontScale | ) |

Sets the scale factor for displaying fonts, for example for more comfortable editing.

void wxRichTextBuffer::SetFontTable | ( | const wxRichTextFontTable & | table | ) |
| inline

Sets table storing fonts, for quick access and font reuse.

void wxRichTextBuffer::SetHandlerFlags | ( | int | flags | ) |
| inline

Sets the handler flags, controlling loading and saving.

static void wxRichTextBuffer::SetRenderer | ( | wxRichTextRenderer * | renderer | ) |
| static

Sets 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.

void wxRichTextBuffer::SetScale | ( | double | scale | ) |
| inline

Sets the scale factor for calculating dimensions.

void wxRichTextBuffer::SetStyleSheet | ( | wxRichTextStyleSheet * | styleSheet | ) |
| inline

Sets style sheet, if any.

This will allow the application to use named character and paragraph styles found in the style sheet.

Neither the buffer nor the control owns the style sheet so must be deleted by the application.

bool wxRichTextBuffer::SetStyleSheetAndNotify | ( | wxRichTextStyleSheet * | sheet | ) |

Sets the style sheet and sends a notification of the change.

virtual bool wxRichTextBuffer::SubmitAction | ( | wxRichTextAction * | action | ) |
| virtual

Submit the action immediately, or delay according to whether collapsing is on.

virtual bool wxRichTextBuffer::SuppressingUndo | ( |  | ) | const
| inline virtual

Are we suppressing undo??
