i have create a modeless qdialog inside a method of a class:
//Test.cpp
QDialogMaintenance *diag = new QDialogMaintenance(this);
diag->show();
diag->raise();
diag->activateWindow();
I can close the dialog only clicking on the "X" icon in the dialog frame. How can i delete the "diag" instance in the test.cpp?
You can use QWidget::setAttribute and set the Qt::WA_DeleteOnClose
attribute.
Makes Qt delete this widget when the widget has accepted the close event (see QWidget::closeEvent()).
diag->setAttribute(Qt::WA_DeleteOnClose);
