EXAMPLES::

subsection:: Basic Example

code::
(
w = Window.new.front;
a = StaticText(w, Rect(10, 10, 200, 20));
a.string = "Rolof's Rolex";
)

// adjust look , alignment and content
a.background=Color.grey;
a.align = \center;
a.font = Font("Monaco", 11);
a.string = "Your Rolex";

subsection:: Monitoring Values in a Synth

code::
(

w = Window("Frequency Monitor", Rect(200, Window.screenBounds.height-200,300,150)).front;

a = StaticText(w, Rect(45, 10, 200, 20)).background_(Color.rand);

a.string = " Current Frequency ";

Button.new(w, Rect(45, 70, 200, 20)).states_([["close",Color.black,Color.rand]]).action_({w.close});

s.waitForBoot({

    b=Bus.new(\control,0,1);

    q=SynthDef(\Docs_FreqMonitor, {var freq,snd;
        freq=LFNoise0.ar(2, 400, 650);
        snd=SinOsc.ar(freq,0,0.2);
        Out.ar(0,snd);
        Out.kr(b.index,freq); // output the frequency to a control bus
    }).play;

    r= Routine{
        {           // Set the value of the StaticText to the value in the control bus.
                    // Setting GUI values is asynchronous, so you must use .defer in the system clock.
                    // Also you must check if the window is still open, since Routine will continue for at least
                    // one step after you close the window.
        b.get( {arg v; {w.isClosed.not.if{ a.string= " Current Frequency: "++v.round(0.01)}; }.defer} );

        0.01.wait;
        }.loop

    }.play
});

CmdPeriod.doOnce({w.close});
w.onClose={r.stop; q.free; b.free }; //clean up if the window closes
