Qt5.12.2 QMessageBox can't be showed on IOS18.2
-
The following code can work correctly on IOS16.7:
void DIAG(QString text)
{
QMessageBox box;
box.setIcon(QMessageBox::NoIcon);
box.setText(text);
box.addButton(QObject::tr("OK"), QMessageBox::AcceptRole);
box.exec();
}But can't work on on IOS18.2!
For example, if I call DIAG function under QPushButton clicked slot, the messagebox can't show and will block the current UI(you can't click anything).
Now I let the APP goto background, and then reopen it, then I can see the messagebox(but still you can't click anything).How to fix this issue on IOS18.2?
Thanks! -
@iamnotsad You should consider switching to QML for mobile platforms. There is not much happening in QtWidgets and they are more for desktop systems.
-
Please also move to at least Qt 6.5.
5.12 isn't supported anymore. -
@jsulm Thanks for your reply!
I kown switch to QML is the best choice. But my raw APP
was based on QWidgets, it will take to long time to switch to QML...
I want to find a workround for this issue firstly.
And next step,we may consider switching to QML when we have resources. -
@iamnotsad Then you should at least use a more recent version of Qt - latest Qt5 or even better Qt6. Qt 5.12 isn't supported anymore for long time already.
