[Solved] Dynamic sourceComponent of Loader and changing property of components

p3c0

Hi

Since you are using a Loader you can access the loaded Component using item. So

Component.onCompleted: {
    if (componentType === "component1") {
        loader.item.text = buttonText
    }
    else if (componentType === "component2") {
        loader.item.text = txt
    }
}

P.S: The editor in this new forum using markdown syntax. So to add a code you can use ``` (3 backticks) with the same followed at the end.

Hi,
Thanks a lot. How do I flag it solved?

You're Welcome :)
There's a topic combobox at the bottom. It has the "Mark Solved" option.

By the way, if I want to change the properties of the components loaded by the loader out of the Loader block, how can that be done? As I understand there is no id of the instances of the components.

@myQtQml in the same way as earlier. Loader would be accessible outside too.

myQtQml

item is the present item being loaded. loader.item.text would give text of which component? There are 4 components loaded by the loader in the above example.

Ok understood, so in that case to access delegates from outside ListView, you will need to use children or you can set an item as current item and then access it

listview.currentIndex=1 // 1 is index of delegate, listview = id of ListView
console.log(listview.currentItem)

myQtQml

I have added the following code to access text of the components

    Button {
        width: 100; height: 40; text: "Get Text";
        anchors.top: listView.bottom
        onClicked: {
            listView.currentIndex = 2   // or anything else (0 - 3)
            console.log(listView.currentIndex, listView.currentItem.text)
        }
    }

The output (listView.currentItem.text) is alway undefined for any value of listView.currentIndex. Am I doing anything wrong?

Ok. Now you have to go further. The currentItem will be the Loader. Try getting children of it

console.log(listView.currentIndex, listView.currentItem.children)

and then try accessing the childrens. It is an array.

Working. Thanks again. I don't see any "Mark Solved" option in Topic Tools combobox.

p3c0

Well I do see it. Its the bottom entry in the combobox . I'll mark it as solved.

Strange I'm to not able to mark it as solved. Clicking doesn't have any effect.
