Returns true if this object is composite.

Reimplemented in wxRichTextCompositeObject.

virtual bool wxRichTextObject::IsEmpty ( ) const

virtual

Returns true if the object is empty.

Reimplemented in wxRichTextImage, wxRichTextPlainText, wxRichTextField, and wxRichTextCompositeObject.

virtual bool wxRichTextObject::IsFloatable ( ) const

virtual

Returns true if this class of object is floatable.

Reimplemented in wxRichTextImage.

virtual bool wxRichTextObject::IsFloating ( ) const

virtual

Returns true if this object is currently floating.

bool wxRichTextObject::IsShown ( ) const

Returns true if the object will be shown, false otherwise.

virtual bool wxRichTextObject::IsTopLevel ( ) const

virtual

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

Reimplemented in wxRichTextField, and wxRichTextParagraphLayoutBox.

virtual bool wxRichTextObject::Layout	(	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 wxRichTextTable, wxRichTextImage, wxRichTextPlainText, wxRichTextParagraph, wxRichTextField, and wxRichTextParagraphLayoutBox.

virtual bool wxRichTextObject::LayoutToBestSize	(	wxDC &	dc,
		wxRichTextDrawingContext &	context,
		wxRichTextBuffer *	buffer,
		const wxRichTextAttr &	parentAttr,
		const wxRichTextAttr &	attr,
		const wxRect &	availableParentSpace,
		const wxRect &	availableContainerSpace,
		int	style
	)

virtual

Lays out the object first with a given amount of space, and then if no width was specified in attr, lays out the object again using the minimum size.

availableParentSpace is the maximum space for the object, whereas availableContainerSpace is the container with which relative positions and sizes should be computed. For example, a text box whose space has already been constrained in a previous layout pass to availableParentSpace, but should have a width of 50% of availableContainerSpace. (If these two rects were the same, a 2nd pass could see the object getting too small.)

virtual bool wxRichTextObject::Merge	(	wxRichTextObject *	object,
		wxRichTextDrawingContext &	context
	)

virtual

Returns true if this object merged itself with the given one.

The calling code will then delete the given object.

Reimplemented in wxRichTextPlainText.

virtual void wxRichTextObject::Move ( const wxPoint & pt )

virtual

Moves the object recursively, by adding the offset from old to new.

Reimplemented in wxRichTextCompositeObject.

void wxRichTextObject::Reference ( )

Reference-counting allows us to use the same object in multiple lists (not yet used).

void wxRichTextObject::SetAttributes ( const wxRichTextAttr & attr )

Sets the object's attributes.

virtual void wxRichTextObject::SetCachedSize ( const wxSize & sz )

virtual

Sets the cached object size as calculated by Layout.

void wxRichTextObject::SetDescent ( int descent )

Sets the stored descent value.

virtual void wxRichTextObject::SetMargins ( int margin )

virtual

Set the margin around the object, in pixels.

virtual void wxRichTextObject::SetMargins	(	int	leftMargin,
		int	rightMargin,
		int	topMargin,
		int	bottomMargin
	)

virtual

Set the margin around the object, in pixels.

virtual void wxRichTextObject::SetMaxSize ( const wxSize & sz )

virtual

Sets the maximum object size as calculated by Layout.

This allows us to fit an object to its contents or allocate extra space if required.

virtual void wxRichTextObject::SetMinSize ( const wxSize & sz )

virtual

Sets the minimum object size as calculated by Layout.

This allows us to constrain an object to its absolute minimum size if necessary.

void wxRichTextObject::SetName ( const wxString & name )

Sets the identifying name for this object as a property using the "name" key.

void wxRichTextObject::SetOwnRange ( const wxRichTextRange & range )

Set the object's own range, for a top-level object with its own position space.

virtual void wxRichTextObject::SetParent ( wxRichTextObject * parent )

virtual

Sets the pointer to the parent object.

virtual void wxRichTextObject::SetPosition ( const wxPoint & pos )

virtual

Sets the object position in pixels.

void wxRichTextObject::SetProperties ( const wxRichTextProperties & props )

Sets the object's properties.

void wxRichTextObject::SetRange ( const wxRichTextRange & range )

Sets the object's range within its container.

virtual void wxRichTextObject::Show ( bool show )

virtual

Call to show or hide this object.

This function does not cause the content to be laid out or redrawn.

virtual wxRichTextObject* wxRichTextObject::Split ( wxRichTextDrawingContext & context )

virtual

Returns the final object in the split objects if this object was split due to differences between sub-object virtual attributes.

Returns itself if it was not split.

Reimplemented in wxRichTextPlainText.

virtual bool wxRichTextObject::UsesParagraphAttributes ( ) const

virtual

Returns true if this object takes note of paragraph attributes (text and image objects don't).

Reimplemented in wxRichTextImage, and wxRichTextPlainText.
