Detailed Description

The parent class for anything that goes on the canvas.

Items have a position, which is expressed in the coordinates of the parent. They also have a bounding box, which describes the area in which they have drawable content, which is expressed in their own coordinates (whose origin is at the item position).

Any item that is being displayed on a canvas has a pointer to that canvas, and all except the ‘root group’ have a pointer to their parent group.

		Cairo::RefPtr< Cairo::Context >
	)		const

pure virtual

Render this item to a Cairo context.

Parameters

area	Area to draw, in window coordinates

Items must convert their own coordinates into window coordinates because Cairo is limited to a fixed point coordinate space that does not extend as far as the Ardour timeline. All rendering must be done using coordinates that do not exceed the (rough) limits of the canvas' window, to avoid odd errors within Cairo as it converts doubles into its fixed point format and then tesselates the results.
