neoscore.western.brace

class neoscore.western.brace.Brace[source]

Bases: MultiStaffObject, MusicText

A brace spanning staves.

This is drawn in the fringe of every staff system in the specified group.

__init__(staves: Union[StaffGroup, List[AbstractStaff]], font: Optional[MusicFont] = None, brush: Optional[Union[Brush, str]] = None, pen: Optional[Union[Pen, str]] = None)[source]
Parameters

  • staves – The staves spanned. If a raw list of staves is given, it must be in descending order.

  • font – If provided, this overrides the font in the parent (top) staff.

  • brush – The brush to fill shapes with.

  • pen – The pen to draw outlines with.

property breakable_length: Unit

This class’s breakable length is that of its highest staff

render_complete(pos: Point, flowable_line: Optional[NewLine] = None, flowable_x: Optional[Unit] = None)[source]

Render the entire object.

This is used to render all objects outside flowables, as well as those inside flowables when they fit completely in one line of the flowable.

By default, this is a no-op. Subclasses with rendered appearances should override this.

This method behaves differently inside and outside of flowables. Whether this object is inside a flowable can be determined by whether a flowable_line is given. When inside a flowable, the given position is in global document coordinates, and created interfaces (or higher level classes) must not be assigned a parent. When not inside a flowable, the given position is relative to self.parent and created interfaces (or higher level classes) must be assigned a parent. In this case, created interfaces should use self.parent.interface_for_children as their parent.

This and other render methods should generally not be called directly.

Parameters

  • pos – The rendering position. If outside a flowable, this is relative to the parent. Otherwise, it is in document coordinates.

  • flowable_line – If in a Flowable, the line in which this object appears

  • flowable_x – If in a Flowable, the flowable x position of this render

render_before_break(pos: Point, flowable_line: NewLine, flowable_x: Unit)[source]

Render the beginning of the object up to a stopping point.

For use in flowable containers when rendering an object that crosses a line or page break. This function should render the beginning portion of the object up to the break.

By default, this is a no-op. Subclasses with rendered appearances should override this.

Created interfaces and higher level objects should not be assigned a parent.

This and other render methods should generally not be called directly.

Parameters

  • pos – The rendering position in document space for drawing.

  • flowable_line – The line in which this object appears

  • flowable_x – The flowable x position of this render

render_spanning_continuation(pos: Point, flowable_line: NewLine, object_x: Unit)[source]

Render the continuation of an object after a break and before another.

For use in flowable containers when rendering an object that crosses two breaks. This function should render the portion of the object surrounded by breaks on either side.

By default, this is a no-op. Subclasses with rendered appearances should override this.

Created interfaces and higher level objects should not be assigned a parent.

This and other render methods should generally not be called directly.

Parameters

  • pos – The rendering position in document space for drawing.

  • flowable_line – The line in which this object appears

  • object_x – The local object x position of the line’s start.

render_after_break(pos: Point, flowable_line: NewLine, object_x: Unit)[source]

Render the continuation of an object after a break.

For use in flowable containers when rendering an object that crosses a line or page break. This function should render the ending portion of an object after a break.

By default, this is a no-op. Subclasses with rendered appearances should override this.

Created interfaces and higher level objects should not be assigned a parent.

This and other render methods should generally not be called directly.

Parameters

  • pos – The rendering position in document space for drawing.

  • flowable_line – The line in which this object appears

  • object_x – The local object x position of the line’s start.

pre_render_hook()[source]

Run code once just before document rendering begins.

Implementations must call the superclass function as well.
