• selected Rows/Line in QTableView copy to QClipboard

  - by Berschi

  Hi. First of all, sorry for bad English. It's about C++ and Qt. I have a SQLite-Database and I did it into a QSqlTableModel. To show the Database, I put that Model into a QTableView. Now I want to create a Method where the selected Rows (or the whole Line) will be copied into the QClipboard. After that I want to insert it into my OpenOffice.Calc-Document. But I have no Idea what to do with the "Selected"-SIGNAL and the QModelIndex and how to put this into the Clipboard. So can you please help me? Berschi

• RESTful interface for C++/Qt ?

  - by Berschi

  I want to integrate the RESTful-API in my Qt-Project. I already read the example on this page, but this is only for receiving data from a RESTful-interface, not for sending new data to the server. In Java, I can use RESTlet for example, is there any possibility to use something like that for Qt, too? Or is there even a simple way to send data from Qt to RESTful, for example when I create a XML before?

• Encrypt/Decrypt SQLite-database and use it "on the fly"

  - by Berschi

  Here's the thing: In my Qt4.6-Project, I use a SQLite-Database. This database shouldn't be unencrypted on my harddrive. So I want, that on every start of my program, the user gets asked to enter a password to decrypt the database. Of course the database never should appear "in clear" (not encrypted) on my harddrive. So is there any possibility to decrypt a SQLite-database "on the fly" and read and write data? What algorithm is here the best (maybe AES)? When it's not possible (or very slow), maybe it's better to encrypt every string in the database and decrypt the string when the password was right (so that a user could open the database, but has no clue what all the entrys could mean)?
