In Qt, how can I ignore all mouse and keyboard events and later stop ignoring them? That is: click a button, ignore all events in children; click again, not ignore. Is that clear? I have the following lines, but maybe I'm doing something wrong:
setAttribute(Qt::WA_TransparentForMouseEvents);
setFocusPolicy(Qt::NoFocus);
You can use Events' filters on your mouse and keyboard events to filter some keypress or mouseclick when you need so :
yourWidget->installEventFilter(this);
...
bool YourFrm::eventFilter(QObject* pObject, QEvent* pEvent)
{
if (pEvent->type() == QEvent::KeyPress)
{
QKeyEvent* pKeyEvent = static_cast<QKeyEvent*>(pEvent);
int PressedKey = pKeyEvent->key();
if(PressedKey == Qt::Key_Return)
{
// Filter Return key....
return true;
}
// standard event processing
return QObject::eventFilter(pObject, pEvent);
}
else if (pEvent->type() == QEvent::MouseButtonPress)
{
QMouseEvent* pMouseEvent = static_cast<QMouseEvent*>(pEvent);
... // etc...
}
else
{
// standard event processing
return QObject::eventFilter(pObject, pEvent);
}
}

Hope it helps !
