DeleteLater() from within activex event handler
-
Hi everyone,
I made a little modification to examples/activeqt/webbrowser example to show my question.
Add QExample class declaration to webaxwidget.h.
It does nothing but alert about deferred deletion of itself.@class QExample: public QObject {
public:
bool event(QEvent* e)
{
if (e->type() == QEvent::DeferredDelete)
QMessageBox::information(0, "1", "DeferredDelete QExample");
return QObject::event(e);
}
};@Add member to MainWindow class
@class MainWindow : public QMainWindow, public Ui::MainWindow
{
...
public:
QExample* ex;
...
}@Its initialization
@MainWindow::MainWindow()
{
ex = new QExample;
...
}@And deleteLater() it from within NavigateComplete event handler.
@void MainWindow::on_WebBrowser_NavigateComplete(QString)
{
ex->deleteLater();
...
}@I expected it must be deleted after application returns to main event loop, but deletion occurs only after closing main window.
Why?Qt 4.8.0 OS windows
Thanks. Sorry for bad english.

5 years later, I came across the same issue. Seems like Deferred deletion does not happen in activeqt.
