3.2.17 bend-interface
The (curved) line representing a bent string.
Available for the 'style
property are 'hold
, 'pre-bend
and
'pre-bend-hold
.
The following properties may be set in the details list.
arrow-stencil
-
The stencil procedure for the
BendSpanner
arrow head. curvature-factor
-
Determines the horizontal part of a bend arrow as percentage of the total horizontal extent, usually between 0 and 1.
bend-arrowhead-height
-
The height of the arrow head.
bend-arrowhead-width
-
The width of the arrow head.
bend-amount-strings
-
An alist with entries for
'quarter
,'half
,'three-quarter
and'full
, which are used to print how much a string is bent. curve-x-padding-line-end
-
For a broken
BendSpanner
, set the padding at the line end to subsequent objects like changedClef
, etc. curve-y-padding-line-end
-
For a broken
BendSpanner
started from a chord the curves don’t match; there is a certain vertical gap specified by this value. dashed-line-settings
-
List of three numeric values representing on, off and phase of a dashed line.
head-text-break-visibility
-
A vector of three booleans to set visibility of the arrow head and the text at a line break. This is important for
'style
set to'hold
,'pre-bend
or'pre-bend-hold
. horizontal-left-padding
-
The amount of horizontal free space between a
TabNoteHead
and the startingBendSpanner
. successive-level
-
An integer used as a factor determining the vertical coordinate of the starting
BendSpanner
. Ifsuccessive-level
is 1, theBendSpanner
starts at theTabNoteHead
. If consecutiveBendSpanner
s are set this value should be set to an appropriate value for the first one; later on, this value is maintained by the engraver. target-visibility
-
A boolean to decide whether the target
TabNoteHead
should be visible. For up-pointing bends this is usually true. y-distance-from-tabstaff-to-arrow-tip
-
This numeric value determines the distance between the
TabStaff
and the arrow head of theBendSpanner
.
User settable properties:
bend-me
(boolean)Decide whether this grob is bent.
details
(list)Alist of parameters for detailed grob behavior. More information on the allowed parameters for a grob can be found by looking at the top of the Internals Reference page for each interface having a
details
property.direction
(direction)If
side-axis
is0
(orX
), then this property determines whether the object is placedLEFT
,CENTER
orRIGHT
with respect to the other object. Otherwise, it determines whether the object is placedUP
,CENTER
orDOWN
. Numerical values may also be used:UP
=1
,DOWN
=-1
,LEFT
=-1
,RIGHT
=1
,CENTER
=0
.style
(symbol)This setting determines in what style a grob is typeset. Valid choices depend on the
stencil
callback reading this property.
This grob interface is used in the following graphical object(s): BendSpanner
, NoteColumn
, NoteHead
and TabNoteHead
.
