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.
