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?
