Hi,
there is a difference between the source and the build version. In the build
version the private variables (those with two underscores) are obfuscated. Use
only private variables if no child class has to access it. Otherwise use
protected variables (those with one underscore).
See
http://manual.qooxdoo.org/1.2.x/pages/core/classes.html#access
for more details.
Regards,
Alex

Hi all,
There seems to be some difference with getting and setting inherited variables
between the build and source version of my app. In the build version when a
child class accesses a variable in the parent class it is "undefined", whereas
in the "source" version it correctly gets the value from the super class.
For example suppose we have a parent class with one variable:
qx.Class.define("variableaccess.Parent",
{
extend : qx.core.Object,
members : {
__restricted : null,
setRestricted : function (a) {
this.__restricted = a;
}
}
});
and a child class that extends it:
qx.Class.define("variableaccess.Child",
{
extend : variableaccess.Parent,
members : {
getRestricted : function () {
return this.__restricted;
}
}
});
and a main class :
/* ************************************************************************
#asset(variableaccess/*)
************************************************************************ */
qx.Class.define("variableaccess.Application",
{
extend : qx.application.Standalone,
members :
{
main : function()
{
this.base(arguments);
var child = new variableaccess.Child();
child.setRestricted(1);
console.log(child.getRestricted());
}
}
});
Running it as "source", the console correctly outputs 1, where in "build" I get
an "undefined".
Thanks!
