Tutorial: Work with windows

Work with windows

stbWindowMgr object provides API to the window manager functionality.
Some methods require windowId field which can be achieved either from stbWindowMgr.windowInit or from stbWebWindow.windowId.

Create new window with specified attributes:

var windowId = stbWindowMgr.windowInit(JSON.stringify({
    url: 'http://domain.com/some.page.html',
    x: 20,
    y: 20,
    width: 640,
    height: 480,
    visible: true,
    backgroundColor: '#000'

Redefine any of window attributes:

stbWindowMgr.windowAttr(windowId, JSON.stringify({
    backgroundColor: '#fff'

Get attributes for the given window:


Change windows visibility:

// make window visible with one of these methods
stbWindowMgr.windowAttr(windowId, JSON.stringify({visible: true}));

// make window invisible with one of these methods
stbWindowMgr.windowAttr(windowId, JSON.stringify({visible: false}));

Close given window:

if ( !stbWindowMgr.windowClose(windowId) ) {
    console.log('Given window closing is failed!');

Also window can be closed from itself:


Load new web document into given window:

if ( !stbWindowMgr.windowLoad(windowId, url) ) {
    console.log('Failed to execute!');

Retrieve IDs of currently existing windows:

console.log('IDs of currently existing windows:', stbWindowMgr.windowList());

Get ID of currently active window:

console.log('ID of currently active window:', stbWindowMgr.windowActive());

It's possible to work with user input on a web pages.
Get information for currently focused UI inputs:

console.log('information for currently focused UI inputs:', stbWindowMgr.GetFocusedInputInfo());

Set text for currently focused HTML element:


Different windows can easily interact with each other via messages.
Receive a message from a window:

stbEvent.onMessage = function ( windowId, message, data ) {
    console.log('sender ID: ' + windowId);
    console.log('message text: ' + message);
    console.log('received data: ' + data);

Send a message with some data to a window with ID 3:

stbWebWindow.messageSend(3, 'Hello!', JSON.stringify({foo: 1000}));
