Hi Николай,

Your reference to dialog does not exist because it is inside a Component,
it is not an item (it is like a class definition, not an instance). I
propose that you update the properties that you want to update from inside
the Button's onClicked in the Dialog. For example, if you add this to your
main Item:

id: root
property string someText

then, in one of the Button.onClicked functions you can add:
root.someText = "Hello world";


To answer your other questions about radio buttons and checkboxes:
- There are currently  no radio buttons in the SDK. There is a
ListItem.ValueSelector which may fit your needs, or otherwise a Column with
multiple ListItems  where selecting one deselects the others may be used.
- Dialog only supports buttons, and this is done on purpose because a
Dialog is there to ask the user to make a choice by pressing one of the
buttons, see http://design.ubuntu.com/apps/building-blocks/dialog
For different needs, there are Popovers and Sheets. See
http://developer.ubuntu.com/api/ubuntu-12.10/qml/mobile/overview-ubuntu-sdk.html#popovers-sheets-and-dialogs
 and http://design.ubuntu.com/apps/building-blocks/popover

Greets,
Tim.
