.updateLayer() means to update some internal stuff, not the GSLayer. So that is not helping.
I would try to apply the transformation to the view, instead scaling the layer. You would need to copy the “GlyphPreview” class and add the a transformation in the drawRect_() function.
I added this for the next version. But if you rename the classes, you can use this code:
# -*- coding: utf-8 -*-
__all__ = ["GlyphPreview"]
import traceback
from GlyphsApp import GSLayer
from AppKit import NSView, NSColor, NSAffineTransform, NSGraphicsContext, NSRectFill
from vanilla.vanillaBase import VanillaBaseObject
class GSGlyphPreviewView(NSView):
_transformation = None
def setGlyph_(self, glyph):
self._glyph = glyph
def setDelegate_(self, delegate):
self._delegate = delegate
def drawRect_(self, rect):
frame = self.bounds()
NSColor.whiteColor().set()
NSRectFill(frame)
try:
if self._transformation:
NSGraphicsContext.saveGraphicsState()
self._transformation.concat()
if self._glyph is not None:
if isinstance(self._glyph, GSLayer):
layer = self._glyph
elif isinstance(self._glyph, RGlyph):
layer = self._glyph._layer
if layer:
layer.drawInFrame_(frame)
except:
print(traceback.format_exc())
finally:
if self._transformation:
NSGraphicsContext.restoreGraphicsState()
def mouseDown_(self, event):
try:
if event.clickCount() == 2:
if self._delegate.mouseDoubleDownCallBack:
self._delegate.mouseDoubleDownCallBack(self)
return
if self._delegate.mouseDownCallBack:
self._delegate.mouseDownCallBack(self)
except:
print(traceback.format_exc())
def mouseUp_(self, event):
try:
if self._delegate.mouseUpCallBack:
self._delegate.mouseUpCallBack(self)
except:
print(traceback.format_exc())

Oh adding a „print()“ is a rather nasty hack. I think I remember Tim having had such a print statement in one of his scripts too, with the comment that it is just for forcing an update.
