Can't create a glyphLineView: getting "variable referenced before assigment" error

[RafalBuchner]

Hi, I don't know what exactly I'm doing wrong.
In the code below I'm trying to create a glyphLineView

from defcon import Font
from defconAppKit.controls.glyphLineView import GlyphLineView
from defconAppKit.controls.glyphSequenceEditText import GlyphSequenceEditText
from vanilla import Window, Slider
class Demo:

    def __init__(self):
        self.font = Font("some/path/to/ufo")
        x,y,p,btnH,txtH = 10, 10, 10,22,17
        try:
            self.w = Window((200, 200), "Demo", minSize=(100, 100))
            self.w.lineViewSizeSlider = Slider((x, y, -p, btnH), minValue=10, maxValue=500, value=100,
            continuous=True, callback=self.lineViewResize)
            y += p + btnH
            self.w.textInput = GlyphSequenceEditText((x, y, -p, btnH), self.font, callback=self.lineViewTextInput)
            y += p + btnH
            self.w.testView = GlyphLineView((x, y, -p, -p))
            self.w.testView.setShowLayers(True)
            self.w.testView.setPointSize(200)
            self.w.open()
        except:
                # Error. Print exception.
                import traceback
                print(traceback.format_exc())

    def lineViewTextInput(self, sender):
        try:
            glyphs = sender.get()
            self.w.testView.set(glyphs)
        except:
                # Error. Print exception.
                import traceback
                print(traceback.format_exc())
    def lineViewResize(self, sender):
        self.w.testView.setPointSize(sender.get())


# Demo()
if __name__ == "__main__":
    from vanilla.test.testTools import executeVanillaTest
    executeVanillaTest(Demo)

This is the output that I'm getting whenever I'm trying to write something using GlyphSequenceEditText instance.

local variable 'strokeColor' referenced before assignment

Any idea what am I doing wrong?

mm I guess there have to first declared as None here

defconAppKit/Lib/defconAppKit/controls/glyphLineView.py

Lines 361 to 362 in 79d8dc0

	fillColor = self._glyphColor
	strokeColor = self._strokeColor

could you make a PR?
