Description
If you place an input field, and the virtual keyboard is open, you can swipe down from the top edge of the keyboard and it will close. There are no ways to disable this behavior. You can click or swipe anywhere in the app without closing the keyboard. But swiping down near the keyboard closes it.
Is there a workarount to prevent this? I don't want the keyboard to close (I attached a video of what it looks like).
Here is callstack when the keyboard closes (from Qt 5.15, but I tried in Qt6 also, the same behavior)

Looks like the keyboard started closes here (file qiosinputcontext.mm)
- (void)gestureStateChanged:(id)sender
{
Q_UNUSED(sender);
if (self.state == UIGestureRecognizerStateBegan) {
qImDebug("hide keyboard gesture was triggered");
UIResponder *firstResponder = [UIResponder currentFirstResponder];
Q_ASSERT([firstResponder isKindOfClass:[QIOSTextInputResponder class]]);
[firstResponder resignFirstResponder]; // keyboard closes here
}
}
The question is, Is it possible to change this behavior so that the keyboard does not close?
