Issue: Custom Tool – getGlyph() returns None

RafaŁ Buchner

I'm creating some awesome Custom Tool.
I'm trying to use the self.getGlyph() method inside overridden becomeActive method. When I'm using getGlyph() in there, it returns None instead of a fontParts object.

Is there maybe another way to do it? or is it a bug? I really need this glyph object when the tool becomes active.

Great! Works! thanks a lot
(I thought that since getGlyph() is BaseEventTool method, it will be more 'proper' to use it instead of CurrentGlyph() )

ps. BaseEventTool.getGlyph() returns None only the first time you activate the tool in a new glyph window; the second time, it does return the current glyph:

custom tool is active
None
<RGlyph 'i' ('foreground') at 4691232360>
custom tool is inactive
custom tool is active
<RGlyph 'i' ('foreground') at 4485911888>
<RGlyph 'i' ('foreground') at 4691234264>

hello @RafaŁ-Buchner,

I don’t really know what BaseEventTool.getGlyph() does… (so not sure if it’s a bug)

why not simply use CurrentGlyph() instead?

here’s an example script based on simpleTool.py:

from mojo.events import BaseEventTool, installTool, uninstallTool
from mojo.drawingTools import *

class MyTool(BaseEventTool):
    
    def setup(self):
        self.position = None
    
    def mouseDown(self, point, clickCount):
        self.position = point
    
    def mouseDragged(self, point, delta):
        self.position = point
    
    def mouseUp(self, point):
        self.position = None

    def becomeActive(self):
        print('custom tool is active')
        print(self.getGlyph())
        print(CurrentGlyph())

    def becomeInactive(self):
        print('custom tool is inactive')
    
    def draw(self, scale):
        if self.position is not None:
            size = 10
            x = self.position.x - size
            y = self.position.y - size
            fill(None)
            stroke(1, 0, 0)
            oval(x, y, size*2, size*2)
    
    def getToolbarTip(self):
        return "My Tool Tip"
    
installTool(MyTool())
