mojo canvas mouseEntered

[okaytype]

I'm learning more about mojo canvas and am having trouble getting mouseEntered/mouseExited to work. Below is a little test script adding a box to the glyph window. mouseDown works. mouseEntered/mouseExited do not. Anyone know whatimdoingwrong?

from vanilla import *
from mojo.events import addObserver, removeObserver
from mojo.canvas import CanvasGroup
from mojo.drawingTools import rect

debug = True

class observerTest(object):

    def __init__(self):
        if debug == True:
            self.w = Window((150, 50), "debug only")
            self.w.bind("close", self.windowClose)
            self.w.open()
        self.setupStuff()

    def setupStuff(self):
        addObserver(self, "doStuff", "glyphWindowWillOpen")

    def windowClose(self, sender):
        removeObserver(self, "glyphWindowWillOpen")

    def doStuff(self, notification):
        self.window = notification["window"]
        self.offsidesUI = CanvasGroup((0, 0, 100, 100), delegate=self)
        self.window.addGlyphEditorSubview(self.offsidesUI)

    def draw(self):
        rect(0, 0, 100, 100)
    def mouseDown(self, event):
        print('mouseDown')
    def mouseEntered(self, event):
        print('mouseEntered')
    def opaque(self):
        return False
    def shouldDrawBackground(self):
        return False

observerTest()

This works perfectly. Thanks for the update.

If anyone else wants to play, here's a simpler canvas test script :

from AppKit import NSApp
from vanilla import *
from mojo.canvas import CanvasGroup
from mojo.drawingTools import rect, fill

debug = True

class CanvasTest(object):

    def __init__(self):
        windowname = 'Canvas Test'
        if debug == True:
            for window in [w for w in NSApp().orderedWindows() if w.isVisible()]:
                if window.title() == windowname:
                    window.close()
        self.w = Window((500, 500), windowname, fullSizeContentView=False)
        self.w.g = CanvasGroup((100, 100, -100, -100), delegate=CanvasStuff())
        self.w.open()

class CanvasStuff(object):

    def draw(self):
        fill(.5, .2, 1,1)
        rect(0, 0, 600, 600)

    def mouseDown(self, event):
        print('mouseDown')
    def mouseUp(self, event):
        print('mouseUp')
    def mouseDragged(self, event):
        print('mouseDragged')

    def mouseEntered(self, event):
        print('mouseEntered')
    def mouseExited(self, event):
        print('mouseExited')

CanvasTest()

Thanks for the explanation. I'll give this another shot when the next beta drops.

a tracking area is needed to catch mouseEntered and mouseExited events – this will be added automatically in the next beta. The default will be the bounds of the view. Canvas objects can overwrite this and add their own tracking rects with a new delegate callback: updateTrackingAreas.
