Dear Alan,
thank you very much for help! We figured it out in this question somehow:))
Below you can see the solution - we can do background image as tabs layout background:
function OnStart() {
lay = app.CreateLayout("linear", "VCenter, FillXY");
var theme = app.CreateTheme("light")
theme.SetTextColor( "blue" )
app.SetTheme( theme );
var tabs = app.CreateTabs("tab1, tab2, tab3", 1, 1, "VCenter");
tabs.SetOnChange( tabs_OnChange );
lay.AddChild( tabs );
layTab1 = tabs.GetLayout("tab1");
layTab1.SetBackground("Img/IMG...");
btn = app.CreateButton("Button");
layTab1.AddChild( btn );
layTab2 = tabs.GetLayout("tab2");
layTab2.SetBackground("Img/IMG...");
layTab3 = tabs.GetLayout("tab3");
layTab3.SetBackground("Img/IMG...");
app.AddLayout( lay );
}
function tabs_OnChange( name ) {
app.Showpopup( name );
}
So all work! Thank you very much for help!
Have a nice day.
Best regards
Dmitry
