Warn about using assignment in conditions
What happened?
You used an assignment inside an if-condition
.
Why is this bad?
This is often a mistake, and a comparison should have been used. If it was intentional, it is still often considered confusing.
Example
import QtQuick Item { id: root Component.onCompleted: { // mistake: should have been a comparison if (width = height) console.log("A square") let mypoint = Qt.point(1,2) let hit = false // intentional, but possibly misleading if (hit = root.contains(myPoint)) console.log("hit") root.enabled = hit } }
To fix this warning, change the assignment to a comparison if it was a mistake. Otherwise, wrap the assignment into parentheses to indicate that it was done intentionally.
import QtQuick Item { id: root Component.onCompleted: { // fixed if (width === height) console.log("A square") let mypoint = Qt.point(1,2) let hit = false // intentional if ((hit = root.contains(point))) console.log("hit") root.enabled = hit } }
