[SOLVED] Update value in QJsonObject
I have a QTreeView that represents a QJsonObject. When I change a value in the tree view, I'd like to update the corresponding value in the QJsonObject.
I tried using myJsonObject.value(key) method to find the value by it's key, but this only works for key:value pairs in the top level of the tree. How can I find a key:value pair that is not on the top level? If I must iterate over it, how can I know if an element in the JSON map is a node or a leaf?
Let me reformulate the question:
I have a QJsonObject that has this structure:
myJsonObject.find("A") returns "a", but myJsonObject.find("Y") returns "undefined" instead of "y". Same for myJsonObject.value("Y"), or myJsonObject.values("X").
How can I find "X" or "Y" in such a structure?
I tried converting QJsonObject to QVariantMap, with the same result.
Since you have a tree, you could follow the branches to get to the value.
i.e you know that X is under G2. You can rebuild the path from your model data (or are you using QTreeWidget ?)
Hope it helps
I'm using a QTreeView.
Your solution makes sense. I'll give it a try. Thanks a lot!
