[Not work?!] TextEdit focus/transform

[Gloglas´s Studio]

Hi guys,
  I am making code editor but i can´t transform textedit when keyboard appear.
  I tried check every 100 miliseconds if is keyboard open and then resize txtedit but there was bug. When you clicked on bottom half of txtedit it made blank space between keyboard and txtedit.
  I also tried use Focus but i can´t get it working.
Please help.

var chg = false;
var clicked = false;
//Called when application is started.
function OnStart() {
    //setup///////
    app.SetOrientation("Portrait");
    app.EnableBackKey(false);

    appl = app.CreateLayout("Linear", "VCenter,FillXY");

    scroll = app.CreateScroller(1.0, 1.0);

    appl.AddChild(scroll);

    app.AddLayout(appl);

    lay = app.CreateLayout("Linear", "VCenter,FillXY");
    scroll.AddChild(lay);
    lay.SetBackColor("#222222");

//Perhaps you can use something based on this.

function OnStart()
{
lay = app.CreateLayout( "linear", "Top,FillXY" );

txt = app.CreateTextEdit("My Code", 0.98, 0.88);
txt.SetTextSize( 32 );
lay.AddChild( txt );
app.SetOnShowKeyboard( keybd );

app.AddLayout( lay );
txt.Focus();
app.ShowKeyboard( txt );
}

function keybd(shown)
{
var width = app.GetScreenWidth( )*0.98
var height = app.GetScreenHeight()*0.88
height -= app.GetKeyboardHeight();
txt.SetSize( width,height,"px");
}

Oh thank you so much!
It won´t work sometimes when you have longer code but i will play with that.
