I want to override a method in qx.ui.core.MBlocker mixin. I want the
_createBlocker : function() { return new qx.ui.core.Blocker(this); }, to use another provided widget instead of this. One option I guess is to call qx.Class.patch() and patch it. I don't want that because this would patch it for the whole application. Another idea was to define a _createBlocker function in the class that uses the mixin but this is not allowed. Another idea was to subclass the mixin but "The configuration key "extend" in mixin "qssite.ui.dialog.MBlocker" is not allowed!" The last option is to copy the contents of that mixin in a new separate mixin and do whatever I want with it. Are there any better options? ------------------------------------------------------------------------------ _______________________________________________ qooxdoo-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/qooxdoo-devel |
Hi voger,
You are able to override mixin methods, not in the class which includes the mixin, but in a subclass of that class. So if class A uses mixin MA having the method _createBlocker, derive class subA from class A and override in subA method _createBlocker.

Thanks. This is a very handy tip.
