c++ - How to save content of the QSettings file on Android to make it readable after updating my app from Play Store? -


I have an application written in C ++, based on QT532 framework. I save the settings of my code with QSettings This works if I only restart my app but if I redistribute my app to Qt Creator or update it to Play Market Then Resetts QSettings in the initial state. I think removing the file associated with QSettings .

I am creating QSettings with the following code: 

  QSettings Settings (QStringLiteral ("Company"), QStringLiteral ("App"), Nullptr);

Thanks!

You can try to specify the location setting file in a writable location then Also exists, even if the application has been deleted: 

  #include & lt; QSettings & gt; # Include & lt; QStandardPaths & gt; QString Path; QString file name; Path = QStandardPaths :: Written Place (QStandardPaths :: GenericDataLocation); File name = "config.ini"; Quitting Settings (Path + "/" + File Name, Quotes :: Informat);

Here QStandardPaths :: GenericDataLocation gives a directory location where the shared data in the applications can be stored continuously and it is never empty.

In addition to this you can set the name of the application and organization in the main of your application: 

  qApp-> Set organization name ("company"); QApp- & gt; SetApplicationName ("application");

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
