A structured access is only possible when you create it as a structure. You
are creating the buttons as vars, not as part of the structure. After you
create the button you are setting it's parent using the add method, but you
are not changing it's scope. It is a var owned by "this". And since it's a
var, you don't have any external access to it directly, but you can walk the
getChildren tree and get to it because of the parent/child relationship. If
you want to access the button the way that you have shown, then create it in
the same tree structure.
eg:
this.toolbar1 = new qx.ui.toolbar();
this.add(this.toolbar1);
this.toolbar1.part = new qx.ui.toolbar.Part();
this.toolbar1.add(this.toolbar1.part);
If you create it in a structure, then you can access it as a structure.
Simply adding an object to another object does not add it to the objects
structure, it just changes it's parent.
