There are a number of other widgets, which support child widgets, e.g.
Windows, Groupboxes, TabPanes, ... They all support the same children
handling interface. If you want to write your own custom widget, which
should have pre configured child widgets but should not expose the
children handling API, you can inherit from qx.ui.core.Widget. The core
widget has the full children handling API as protected methods. This is
why e.g. Button does not have a public "add" method".

setWidth and setHeight set the widget's preferred size in Pixel. The
default value of 'null' means the widget is auto sized. In addition
most layout manager support further hints of how a widgets size should
be calculated. These layout hints can be set as second parameter when
adding the widget to the parent "parent.add(child, {flex:1})" or by
using the setLayoutproperties
<http://demo.qooxdoo.org/current/apiviewer/#qx.ui.core.LayoutItem~setLayoutProperties>
method "child.setLayoutProperties({flex: 1})". In the layout properties
you can set percent, or flex values. You find more information about the
specific layout at the layout reference
<http://qooxdoo.org/documentation/0.8/layout>.

You don't have to set the row/column count manually. Just add a widget
to any empty cell.

This is an open bug and currently not possible.

We'll check that, thanks.

This means that this class is meant to be used only be the framework.
You should use this class directly in your code. We may break the API
without warning.

I hope this helps,
