Hi Mustafa,

I can see your dilemma. The easy way of most qooxdoo widgets just to
extend and add some more child controls is difficult in qx.ui.form.List().
Because it extends from qx.ui.core.scroll.AbstractScrollArea. The scroller
uses normally grid layout. Adding on top of it means to override the whole
_createChildControlImpl.
exactly. This is what I did so far, having the disadvantage that when
something is changed in qx.ui.form.List() in future versions of Qooxdoo I
will have to modify _creatChildControlImpl again (which is easily overlooked
if functionality doesn't break completely).
I guess my example http://tinyurl.com/kfc2a7u can be a nice wrapper. This
solution allows you to access directly to the api of form-list. I just
created a list and injected it as a childcontrol into a wrapper which also
holds the toolbar.
But doesn't that mean that I'd have to implement all methods of
qx.ui.form.List() in class myList as well (and there call the corresponding
method of the "internal" list)? Including all the inherited methods?
Cheers,
Fritz
Hope I could help.

Betreff: [qooxdoo-devel] How to extending qx.ui.form.List()
Hi,
I need to extend qx.ui.form.List() to have a form widget with two buttons (add
and clear) for manipulation the selection of elements in the list:
-------------
| All | Clr |
-------------
| Item 1 |
| Item 2 |
| Item 3 |
| Item 4 |
| ... |
-------------
The All and Clr buttons should be outside the scroll area of the List widget
(e.g. NOT be scrolled).
My question is: how can I create such a widget in a Qooxdoo-OO way (that is
without copying too much code)?
Is it somehow possible to extend qx.ui.formm.List() and "insert" the two
buttons into the widgets layout?
Or do I have to create a wrapper widget (using a container widget)? In this
case, is there an efficient way to wrap all the List widget methods as well?
Thanks,
Fritz
