Hello Andreas,
you can take HBox layout and add two spacers to the edges. The middle part
can have a fixed width which is exactly what you want (i guess).
Take a look at the following code, which you can test in the online
playground:
http://demo.qooxdoo.org/devel/playground/
// create a composite for the whole document
var composite = new qx.ui.container.Composite();
composite.setBackgroundColor("red");
// add it to the document with all edges 0
this.getRoot().add(composite, {left: 0, right: 0, top: 0, bottom: 0});
// set a horizontal box layout
composite.setLayout(new qx.ui.layout.HBox());
// add the first spacer with a flexible width
composite.add(new qx.ui.core.Spacer(), {flex: 1});
// add the inner composite with a fixed width
var innerComposite = new qx.ui.container.Composite();
innerComposite.setWidth(100);
innerComposite.setBackgroundColor("black");
composite.add(innerComposite);
// add a second spacer with a flexible width
composite.add(new qx.ui.core.Spacer(), {flex: 1});
Regards,
Martin
