you can remove those lib keys from the glyph lib:

com.fontlab.v2.tth
com.fontlab.ttprogram

be careful, the data will be lost. Converting the ufo back to vfb will not be able to restore the removed hinting data.

oh, here is an example, it is required to install the drawBot extension, get it here: https://github.com/typemytype/drawBotRoboFontExtension

import drawBot
from drawBot.ui.drawView import DrawView

from vanilla import *

class Test(object):
    
    def __init__(self):
        
        self.w = Window((400, 400), minSize=(200, 200))
        
        self.w.s = Slider((10, 10, -10, 22), minValue=10, maxValue=100, value=50, callback=self.sliderCallback)
        self.w.c = DrawView((10, 40, -10, -10))
        
        self.w.open()

    def sliderCallback(self, sender):
        value = sender.get()
        # start a new drawing
        drawBot.newDrawing()
        # add a page
        drawBot.newPage(100, 100)
        # draw something
        drawBot.rect(10, 10, value, value)
        # get the pdf data
        pdf = drawBot.pdfImage()
        # set the pdf data in the canvas
        self.w.c.setPDFDocument(pdf)

Test()

good luck!

Hi Roberto

In your example you don’t have a canvas object that is able to show drawing callbacks.

Please see the example http://doc.robofont.com/api/mojo/mojo-canvas/

The slider just tells the canvas object to redraw itself. While getting a draw callback some drawBot methods are called to draw something into the canvas

hope this helps

good luck!

oh, I guess changes in the os…

It seems this opens the window after the script is done.
Pretty annoying

from vanilla import *
import time

w = Window((250, 70))
w.p = ProgressBar((10, 10, -10, 22), maxValue=20)
w.p.start()

w.open()


for i in range(20):
    time.sleep(.05)
    w.p.increment()

This is been solved already in the beta of the upcoming 1.7 release

I would not recommend to fiddle around in the zipped site packages (fe: the code signing will be broken)

Hi

What concerns me a little bit is the different path to the xmlWriter, why it using an other one then the one embedded in RoboFont?
Did you install something specific? or changed some files in the package?

FontTools is embedded in RoboFont and I would not advice to use an other version, as many things changed between versions of FontTools…
The same goes for roboFab and ufo2fdk, both packages are embedded in RoboFont.

You can install those packages if you need them outside RoboFont but internally I would not change the content of any package.

how did you install ufo2otf? from inside RoboFont or did you use terminal?

Im aware of that option and this will be implemented, but still there is something wrong with the provided date to the binary ttf compiler…

if you want to receive those notifications, just add this .py file to the start up scripts in your preferences. This doesn’t effect performance, unless to your part of the code, what is been executed when the notification is been send, takes a while.
