As a newbie here myself, I struggled with the same issue. I found myself
usually starting by extending other layout objects (see qx.ui.layout.*).
Here is a simple example of an object (I’m sure the smarter people on this
list will have much better examples):
qx.Class.define("foo.SimpleLayoutWithTabView",
{
extend : qx.ui.layout.CanvasLayout,
construct : function()
{
this.base(arguments);
this._tabView = new qx.ui.pageview.tabview.TabView;
this.add(this._tabView);
this._tabView.set({ top: 30, bottom: 0, width: "100%"});
},
destruct : function() {
this._disposeObjects("_tabView");
}
});

You do not have a 'canvas' in qooxdoo right now. There is no way to 'paint'
points and lines. There is a graphics package by Walter Zorn that can be
used together with qooxdoo to be able to do lines and shapes, give that a
look.
As for what to subclass from, that depends on what you want to create.
Choose the control that is closest to what you want to create and start from
there. When in doubt, start from the base Object and work up.

I want to develop some new wigets but im not sure whats the best way to
start....
Which class shall i extend as base class when i need to paint own graphics?
How can i paint lines, points and so for that widget (so that i can
paint things like a progress bar and so on)?
Is there something similar than the graphics api in java?
Hope someone has an idea....
