Class QScopedPointer<O>

java.lang.Object
io.qt.core.QScopedPointer<O>
All Implemented Interfaces:
AutoCloseable
public final class QScopedPointer<O> extends Object implements AutoCloseable

Java wrapper for Qt class QScopedPointer to be used inside a try-with-resource block.

Example:

try(var pointer = QScopedPointer.disposing(new QDialog())){
    QDialog dialog = pointer.get();
    dialog.exec();
}
// dialog is disposed

Alternatively, performAndDispose disposes a recource after calling a lambda expression:

QScopedPointer.performAndDispose(QDialog::exec, new QDialog());
