No. If you don't want a memory leak, then create the QChartView with the MainWindow as a parent. The chart view will then be deleted when the main window is deleted, whether the chart view is visible or not.I should use the delete chartView somewhere near end of function?

Re: Display own widget in new window
No, no. Your QChartView should be a child of MainWindow. See that there are two QChartView constructors; in Line 21 of your code above use the one that takes a QWidget * parent argument and use "this" (your MainWindow instance) as the value for "parent".How to create QChartView as a parent of MainWindow?
