virtual

Reimplemented from ArdourCanvas::Item.

◆ compute_bounding_box()

void ArdourCanvas::Rectangle::compute_bounding_box ( ) const
virtual

Update _bounding_box and _bounding_box_dirty

Implements ArdourCanvas::Item.

Reimplemented in ArdourCanvas::FollowActionIcon, and ArdourCanvas::Table.

◆ dump()

void ArdourCanvas::Rectangle::dump ( std::ostream &  ) const
virtual

Reimplemented from ArdourCanvas::Item.

inline

Definition at line 62 of file canvas/canvas/rectangle.h.

◆ render()

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

Render this item to a Cairo context.

Parameters
areaArea 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.

Reimplemented in ArdourCanvas::Ruler, and ArdourCanvas::FollowActionIcon.

◆ set()

void ArdourCanvas::Rectangle::set ( Rect const &  )

◆ set_corner_radius()

void ArdourCanvas::Rectangle::set_corner_radius ( double  d)

◆ set_outline_all()

void ArdourCanvas::Rectangle::set_outline_all ( )
inline

Definition at line 99 of file canvas/canvas/rectangle.h.

◆ set_outline_what()

void ArdourCanvas::Rectangle::set_outline_what ( What  )

◆ set_x0()

void ArdourCanvas::Rectangle::set_x0 ( Coord  )

◆ set_x1()

void ArdourCanvas::Rectangle::set_x1 ( Coord  )

◆ set_y0()

void ArdourCanvas::Rectangle::set_y0 ( Coord  )

◆ set_y1()

◆ size_request()

void ArdourCanvas::Rectangle::size_request ( double &  w,
double &  h 
) const
virtual

Reimplemented from ArdourCanvas::Item.

Reimplemented in ArdourCanvas::Table.

◆ vertical_fraction()

double ArdourCanvas::Rectangle::vertical_fraction ( double  y) const

return y as a floating point fraction of the overall height of the rectangle. y is in canvas coordinate space.

A value of zero indicates that y is at the bottom of the rectangle; a value of 1 indicates that y is at the top.

Will return zero if there is no bounding box or if y is outside the bounding box.
