Member Function Documentation

◆ child_changed()

void ArdourCanvas::Grid::child_changed ( bool bbox_changed )

protectedvirtual

Reimplemented from ArdourCanvas::Item.

◆ compute_bounding_box()

void ArdourCanvas::Grid::compute_bounding_box ( ) const

virtual

Update _bounding_box and _bounding_box_dirty

Implements ArdourCanvas::Item.

◆ place()

void ArdourCanvas::Grid::place	(	Item *	,
		double	x,
		double	y,
		double	col_span = `1`,
		double	row_span = `1`
	)

◆ render()

void ArdourCanvas::Grid::render	(	Rect const &	area,
		Cairo::RefPtr< Cairo::Context >
	)		const

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.

Implements ArdourCanvas::Item.
