## Detailed Description

The base class for custom field types.

Each type definition handles one field type. Override functions to provide drawing, layout, updating and property editing functionality for a field.

Register field types on application initialisation with the static function wxRichTextBuffer::AddFieldType. They will be deleted automatically on application exit.

## Constructor & Destructor Documentation

wxRichTextFieldType::wxRichTextFieldType | ( | const wxString & | name = `wxEmptyString` | ) |

inline

Creates a field type definition.

wxRichTextFieldType::wxRichTextFieldType | ( | const wxRichTextFieldType & | fieldType | ) |

inline

Copy constructor.

## Member Function Documentation

virtual bool wxRichTextFieldType::CanEditProperties | ( | wxRichTextField * | obj | ) | const

inlinevirtual

Returns true if we can edit the object's properties via a GUI.

void wxRichTextFieldType::Copy | ( | const wxRichTextFieldType & | fieldType | ) |

inline

virtual bool wxRichTextFieldType::Draw | ( | wxRichTextField * | obj,
|  | wxDC & | dc,
|  | wxRichTextDrawingContext & | context,
|  | const wxRichTextRange & | range,
|  | const wxRichTextSelection & | selection,
|  | const wxRect & | rect,
|  | int | descent,
|  | int | style
| ) |  |

pure virtual

Draw the item, within the given range.

Some objects may ignore the range (for example paragraphs) while others must obey it (lines, to implement wrapping)

Implemented in wxRichTextFieldTypeStandard.

virtual bool wxRichTextFieldType::EditProperties | ( | wxRichTextField * | obj,
|  | wxWindow * | parent,
|  | wxRichTextBuffer * | buffer
| ) |  |

inlinevirtual

Edits the object's properties via a GUI.

wxString wxRichTextFieldType::GetName | ( |  | ) | const

inline

Returns the field type name.

There should be a unique name per field type object.

virtual wxString wxRichTextFieldType::GetPropertiesMenuLabel | ( | wxRichTextField * | obj | ) | const

inlinevirtual

Returns the label to be used for the properties context menu item.

virtual bool wxRichTextFieldType::GetRangeSize | ( | wxRichTextField * | obj,
|  | const wxRichTextRange & | range,
|  | wxSize & | size,
|  | int & | descent,
|  | wxDC & | dc,
|  | wxRichTextDrawingContext & | context,
|  | int | flags,
|  | const wxPoint & | position = `wxPoint(0, 0)`,
|  | const wxSize & | parentSize = `wxDefaultSize`,
|  | wxArrayInt * | partialExtents = `NULL`
| ) |  | const

pure virtual

Returns the object size for the given range.

Returns false if the range is invalid for this object.

Implemented in wxRichTextFieldTypeStandard.

virtual bool wxRichTextFieldType::IsTopLevel | ( | wxRichTextField * | obj | ) | const

inlinevirtual

Returns true if this object is top-level, i.e. contains its own paragraphs, such as a text box.

Reimplemented in wxRichTextFieldTypeStandard.

virtual bool wxRichTextFieldType::Layout | ( | wxRichTextField * | obj,
|  | wxDC & | dc,
|  | wxRichTextDrawingContext & | context,
|  | const wxRect & | rect,
|  | const wxRect & | parentRect,
|  | int | style
| ) |  |

pure virtual

Lay the item out at the specified position with the given size constraint.

Layout must set the cached size. rect is the available space for the object, and parentRect is the container that is used to determine a relative size or position (for example if a text box must be 50% of the parent text box).

Implemented in wxRichTextFieldTypeStandard.

void wxRichTextFieldType::SetName | ( | const wxString & | name | ) |

inline

Sets the field type name.

There should be a unique name per field type object.

virtual bool wxRichTextFieldType::UpdateField | ( | wxRichTextBuffer * | buffer,
|  | wxRichTextField * | obj
| ) |  |

inlinevirtual

Update the field.

This would typically expand the field to its value, if this is a dynamically changing and/or composite field.
