Answer 1

This issus is over. I add a Rectangle in root. and add a signal. In Tab page, according to the signal, call the funcion to change control info. get control info.

In the main pange Like this:

    Rectangle
    {
        id:uiManager;

        x:0;
        y:200;
        width:0;
        height:0;
        color:"#FFFF0000";
        property  int  add;
        signal setKeyValue;
    }

In Tab page like this:

Connections
{
    target: uiManager;
    onSetKeyValue:
    {
        console.log("test Page0");
        uiManager.add = 10;
        console.log(uiManager.add);
    }
}
