How can I avoid a QDialog close?

[ricardo]

It seems if I rewrite
void CSequencesDialog::closeEvent(QCloseEvent *event) {
works, but if I try to write
event->accept();
Or
event->ignore();

Any idea?

[ricardo]

Bad news. I read this on Qt docs:

"If the user presses the Esc key in a dialog, QDialog::reject() will be called. This will cause the window to close: The close event cannot be ignored."

So, is that impossible?

Thanks.

May be you can try overriding QWidget::keyPressEvent or QWidget::keyReleaseEventand compare something like -

if(event->key() == Qy::Key_Esc)
    event->ignore();  // or do nothing, dont call base call function for this case

if(event->key() == Qy::Key_Esc)
    event->ignore();  // or do nothing, dont call base call function for this case

I have a similar problem if I use keyPressEvent. It seems parameter is not recognized.

you forgot to include

#include <QKeyEvent>

#include <QKeyEvent>

Thanks a lot, it worked.
