Inheritance diagram for wxRichTextField:

Detailed Description

This class implements the general concept of a field, an object that represents additional functionality such as a footnote, a bookmark, a page number, a table of contents, and so on.

Extra information (such as a bookmark name) can be stored in the object properties.

Drawing, layout, and property editing is delegated to classes derived from wxRichTextFieldType, such as instances of wxRichTextFieldTypeStandard; this makes the use of fields an efficient method of introducing extra functionality, since most of the information required to draw a field (such as a bitmap) is kept centrally in a single field type definition.

The FieldType property, accessed by SetFieldType/GetFieldType, is used to retrieve the field type definition. So be careful not to overwrite this property.

wxRichTextField is derived from wxRichTextParagraphLayoutBox, which means that it can contain its own read-only content, refreshed when the application calls the UpdateField function. Whether a field is treated as a composite or a single graphic is determined by the field type definition. If using wxRichTextFieldTypeStandard, passing the display type wxRICHTEXT_FIELD_STYLE_COMPOSITE to the field type definition causes the field to behave like a composite; the other display styles display a simple graphic. When implementing a composite field, you will still need to derive from wxRichTextFieldTypeStandard or wxRichTextFieldType, if only to implement UpdateField to refresh the field content appropriately. wxRichTextFieldTypeStandard is only one possible implementation, but covers common needs especially for simple, static fields using text or a bitmap.

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

An application can write a field to a control with wxRichTextCtrl::WriteField, taking a field type, the properties for the field, and optional attributes.

virtual

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

Reimplemented from wxRichTextObject.

virtual wxRichTextObject* wxRichTextField::Clone ( ) const

inlinevirtual

Clones the object.

Reimplemented from wxRichTextParagraphLayoutBox.

void wxRichTextField::Copy ( const wxRichTextField & obj )

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

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)

Reimplemented from wxRichTextParagraphLayoutBox.

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

virtual

Edits the object's properties via a GUI.

Reimplemented from wxRichTextObject.

wxString wxRichTextField::GetFieldType ( ) const

inline

virtual wxString wxRichTextField::GetPropertiesMenuLabel ( ) const

virtual

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

Reimplemented from wxRichTextObject.

virtual bool wxRichTextField::GetRangeSize	(	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

virtual

Returns the object size for the given range.

Returns false if the range is invalid for this object.

Reimplemented from wxRichTextParagraphLayoutBox.

virtual wxString wxRichTextField::GetXMLNodeName ( ) const

inlinevirtual

Returns the XML node name of this object.

This must be overridden for wxXmlNode-base XML export to work.

Reimplemented from wxRichTextParagraphLayoutBox.

virtual bool wxRichTextField::IsAtomic ( ) const

inlinevirtual

If a field has children, we don't want the user to be able to edit it.

Reimplemented from wxRichTextCompositeObject.

virtual bool wxRichTextField::IsEmpty ( ) const

inlinevirtual

Returns true if the buffer is empty.

Reimplemented from wxRichTextCompositeObject.

virtual bool wxRichTextField::IsTopLevel ( ) const

virtual

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

Reimplemented from wxRichTextParagraphLayoutBox.

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

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).

Reimplemented from wxRichTextParagraphLayoutBox.

void wxRichTextField::SetFieldType ( const wxString & fieldType )

inline

virtual bool wxRichTextField::UpdateField ( wxRichTextBuffer * buffer )

virtual

Update the field; delegated to the associated field type.

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