How to save code in QML

ACaldas

Hi all!

I wonder if we could somehow save code in cases like this. Is it possible in a QML context?

onToggled: {
                                    bc.checked = false
                                    bb.checked = false
                                    bd.checked = false
                                    spinBox1.enabled = false
                                    spinBox2.enabled = false
                                    spinBox3.enabled = false
                                    spinBox4.enabled = false
                                    spinBox5.enabled = false
                                    spinBox1.value = 0
                                    spinBox2.value = 0
                                    spinBox3.value = 0
                                    spinBox4.value = 0
                                    spinBox5.value = 0
                                }

Thanks for replying.

It's not clear to me what save means in this case. Is the goal to reduce the number of lines of code, write it to a file, write the values to a file, or something else?

I persist data for: application, runtime mode & user preference's via both:

I typically persist single values and rather not complex types or anything - just strings and numbers. But I do also persist QColor types as well.

I use labs qml settings for user preferences and on windows it dumps that in the registry, which is good as I like to keep separated multiple QSettings files for application config and different application mode config files.

Exactly. There's so much lines for the same goal (to disable the instances spinBoxes).
I thought that there should be a syntax in qml so that the action affects these five spinBox once instead of line by line.

@ACaldas If they're all visual children of a container item, this imperative block works:

onToggled: {
    for (var child in parentItem.children) {
        if (undefined !== parentItem.children[child].checked) {
            parentItem.children[child].checked = false;
        }
        else if (undefined !== parentItem.children[child].enabled) {
            parentItem.children[child].enabled = false;
            parentItem.children[child].value = 0;
        }
    }
}

You might also look into either directly binding the values, or using a State. I don't think that these will result in fewer lines, but the relationships might be easier to understand and modify when necessary.
