The basic process of only one method getting called still holds – the whole stack only gets called if EVERY method in the stack calls its superclass method – whether by super() or directly. Double-Sided Glow Paint Board 2 in 1 Glow in The Dark Drawing Pad and Dry Erase Board with Light Up Black Light Pen and Dry Erase Marker (Black) Double-sided. Super() does not assure that all the superclasses’ methods get called – rather, what it does is assure that each one in the MRO gets called only once. Light felt marking that absorbs paint well and allows pasty. Always confirm current lead times with your TXD Representative. SImpleMixin’s init isn’t calling anything else, so wx.Frame’s init never gets called. White cardboard for acrylic paint of 360 g. Some products vary from the listed availability lead times. SimpleFrame’s init is calling super()'s init, which calls SimpleMixin’s init – but then it’s done. That last one is killing you – nothing is calling wx.Frame’s init and every occurrence of the method needs to use super() Buy Tonalite Paintboard Bianco - Guaranteed Lowest Prices - Family Owned and Operated - Stocking Floor and Wall Tile, Thinsets, Grouts, Underlayments.the caller and callee need to have a matching argument signature.the method being called by super() needs to exist.Yup – there are three guidelines for using super – and both seminal articles: RuntimeError: super-class init() of type SimpleFrame was never shows that the init() methods of both the subclass and the mixin were called and completed in the expected order, so I don’t understand why I’m seeing this error message. When I run this program, I get the following python simple.py Apply to metal, wood, masonry, drywall, plaster, glass, concrete, unglazed ceramics and ha. So I’ve created a small sample program that illustrates the problem using a very simple mixin class: simple.pyĬlass SimpleMixin(): def _init_(self, name=None):Ĭlass SimpleFrame(SimpleMixin, wx.Frame): def _init_(self, parent, name=None): Rust-Oleum Chalkboard converts surfaces into a usable chalkboard. Dabo works mainly by the use of mixin classes that add a consistent interface to all objects, but these mixins can make debugging difficult sometimes.Īs I’ve progressed, I’m now seeing the error message in the subject appearing consistently. As I mentioned in a previous message, I’m trying to get Dabo to work with Python3 and wxPython 4.x.
