that would be currentGlyphChanged...

Hello again! My weekend robofont training (self imposed) continues, and I may have discovered a bug. I am attempting a live update on the compatibility of two glyphs from different fonts. The idea at its most basic could manifest as a red mark drawn to the glyph window canvas whenever the glyph becomes incompatible whilst you are drawing/editing the glyph. I am using isCompatible() and a glyph.changed observer It reports when I make a change to the glyph, calling a function that for now simply prints the result of isCompatible. It works fine if I remove a contour, and it works fine if I add a point to an existing contour using knife, but it seems to crash if I use the bezier tool to start drawing a new contour. I have a gist here, please try to replicate the error. https://gist.github.com/MBurvill/fb6772f9e8bc49e583f16e6dc650b7d8#file-isCompatibleObserverBugTest-py FYI I found the useage of glyph.changed in one of Frederiks examples (stencil preview), but usage of this observer appears to be undocumented, I would expect to be able to find it at http://doc.robofont.com/api/custom-observers/ Thanks!

Nice, thank you!

there is Glyph.selection.Changed notification small example also don't forget to remove the observer when your are done... class SelectionObsever(object): def __init__(self): self.g = CurrentGlyph() self.g.addObserver(self, "selectionChanged", "Glyph.selectionChanged") def selectionChanged(self, notification): glyph = notification.object for anchor in glyph.anchors: print anchor.selected SelectionObsever()

Hi Frederik, Ouch, I will see if I can get this to work, may thanks!

hey frederik, I was sooo close … Thanks a lot for your help, working perfectly now. jo

Yes, that will work. Thanks!

Yes that is possible only you have to tell a glyphview to redraw it self Use UpdateCurrentGlyphView() and off course subscribe to the draw notification See http://doc.robofont.com/api/mojo/mojo-ui/ (Will fix the oldstyle notification)

He I've written a proper vanilla patch which is already in the vanilla repo. This will be in the next update of RoboFont. It adds addToolBarItem and removeToolbarItem to a vanilla window object, able to manage toolbar items properly. see https://github.com/typesupply/vanilla/blob/master/Lib/vanilla/vanillaWindows.py#L631

That is easy: subscribe to newFontDidOpen and do something with the new font. from mojo.events import addObserver class SetInfo(object): def __init__(self): addObserver(self, "myCallback", "newFontDidOpen") def myCallback(self, info): font = info["font"] print font font.info.copyright = "This is my font" SetInfo() and maybe set this script as start up script in the preferences so each time you open RoboFont the observer will be installed. good luck

This seems to fix my problem, thanks so much! One more thing, what would be the name of the observer for if a glyph is modified?—so that I can update the preview as you make changes. Is there a list somewhere of all the built in observers? Cheers!

great! thanks

Why is info a dict instead of an instance of a reall class defined in mojo.events? I ask about source code because __doc__ seems to be empty for all the mojo.* modules and classes, and the API documentation is missing a lot. I'm looking for a way to supplement my understanding of the API without asking you a hundred questions.
