Font Collection Custom Tool

  • Is there a safe way of adding tools to the font collection window, or is that not a good idea?

    For example, if I wanted to add a button (say, next to Edit With…) that displayed the current font's notes in a new window, would that be possible?

    that is easy

    from mojo.UI import CurrentFontWindow
    from AppKit import NSImageNameAdvanced
    class AddToolBarButton(object):
        def __init__(self):
            # maybe subscribe to the "fontDidOpen" event
            # get the current window
            window = CurrentFontWindow()
            if window is None:
            # get the current toolbar items
            toolbarItems = window.getToolbarItems()
            # make a new one, see the vanilla docs for more info
            newItem = dict(itemIdentifier="myNewButton",
            # add the new item to the existing toolbars
            # get the vanilla window object
            vanillaWindow = window.window()
            # set the new toolbaritems in the window
            window.toolbar = vanillaWindow.addToolbar(toolbarIdentifier="myCustomToolbar", toolbarItems=toolbarItems, addStandardItems=False)
            # done
        def myCallback(self, sender):
            print "hit, do something!"

    good luck!

  • Haha, it's easy if you say so, frederik.

    Is there a list of the observable events that RoboFont supports? I assume that I can just read through the source of defcon to find its events...

    There are several kinds of notification systems in RoboFont. There is one on font data, the defcon notifications. Another one is on app level, specific build for tools and extension to use and the last one is on cocoa level, UI only.


  • Not to let all of your tricks out of the bag, but is there a shortcut available to set the icons as PDFs like you're doing in other parts of the application?

    My ObjC abilities are poor, and I'm not sure if this is a job for NSPDFImageRef or…?

  • Well, I've gotten past that hurdle by reading the the NSImage docs, now I just need to figure out how the "view" option works for the vanilla addToolbar method (as I'm trying to match the style of the Glyph view buttons. I snooped around and found that the toolbar in the Glyph view is using a view called ToolbarGlyphTools, and I think that I'm importing that module from lib.UI.toolbarGlyphTools. Not sure how to get this hooked up because this doesn't seem to work. Maybe I'm barking up the wrong tree…

    from lib.UI.toolbarGlyphTools import ToolbarGlyphTools
    newItem = dict(itemIdentifier="myNewButton",
            view = ToolbarGlyphTools.alloc().init()

    not sure how to do code tags either…

    The ToolbarGlyphTools is an UI object that looks like a button that you can add in a toolbar dict item.


    from AppKit import NSImage
    from lib.UI.toolbarGlyphTools import ToolbarGlyphTools
    ## create your image, best is that the image is only black and white
    ## so the image can be inverted when clicked
    myToolBarImage = NSImage.alloc().initByReferencingFile_(imagePath)
    ## a ToolbarGlyphTools is similar like the vanilla.SegmentedButton but has an extra toolbar item attributes
    ## if you want to add more items to the segmented button the item attributes just contains more dicts 
    ## the size of the segmented button is atomically multiplied by the number of items.
    toolbarView = ToolbarGlyphTools((30, 25), 
            [dict(image=myToolBarImage, toolTip="My ToolTip"], 
    newItem = dict(itemIdentifier="myNewButton",

    good luck

    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.
