QML遍歷查詢子元素

這里要查詢一個一個Repeater中嵌套的一個Repeater的Image中的圖片是什么. 從而進行屬性操作. 要注意的就是普通控件獲取children后, 用[]下標即可操作子元素, Repeater要用itemAt函數操作子元素.

for(var i = 0; i < items; ++i)
{
    console.log("lineRep["+ i + "] id =      ", lineRep.itemAt(i))      //打印出子控件的類型
    var childItems = lineRep.itemAt(i).children
    console.log("   childitems count : " + childItems.length)
    //第二段是我需要的, 所以這里沒有遍歷, 直接設置j = 1的. 
    var j = 1
    console.log("   childItems["+ j + "] id =      ", childItems[j])      //打印出子控件的類型
    var grandChidlItems = childItems[j].children
    var childRepC = grandChidlItems[2].count
    console.log("       childRep count = " + childRepC)
    for(var k = 0; k < childRepC; ++k)
    {
        console.log("       childRepson[" + k + "] id = ", grandChidlItems[2].itemAt(k))      //打印出子控件的類型
        var childRepSons = grandChidlItems[2].itemAt(k).children
        console.log("           childRepSons count = ", childRepSons.length)
        for(var l in childRepSons)
        {
            console.log("           childRepSons["+ l + "] id =      ", childRepSons[l])      //打印出子控件的類型
            console.log("               childRepSonsSon[" + l + "] source = ", childRepSons[l].source)      //達到目標, 獲取到了圖片的名稱.
        }
    }
}
