io.qt.core.QScopedPointer<O>
- All Implemented Interfaces:
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());
