	)

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)

Implements wxRichTextObject.

wxRichTextObject* wxRichTextParagraph::FindObjectAtPosition ( long position )

Finds the object at the given position.

virtual bool wxRichTextParagraph::FindPosition	(	wxDC &	dc,

		const wxPoint &	pt,
		long &	textPosition,
		wxRichTextObject **	obj,
		wxRichTextObject **	contextObj,
		int	flags = `0`
	)

virtual

Hit-testing: returns a flag indicating hit test details, plus information about position.

contextObj is returned to specify what object position is relevant to, since otherwise there's an ambiguity. @ obj might not be a child of contextObj, since we may be referring to the container itself if we have no hit on a child - for example if we click outside an object.

The function puts the position in textPosition if one is found. pt is in logical units (a zero y position is at the beginning of the buffer).

Returns: One of the wxRichTextHitTestFlags values.

		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).

Implements wxRichTextObject.
