I’ve developed a small Qt Quick application called ColorConv that can convert RGB color to HEX color used in HTML pages (e.g. 255,255,255 -> #FFFFFF) and vice versa mainly to play with Qt Creator QML and test Nokia Ovi Store application submission process.
You can enter the Red, Green, Blue values manually by typing with the default numerical keypad in Symbian or use the slider to select the value. Alternatively you can enter the hexadecimal code to get the RGB value.
Nokia submission process is almost free (1 Euro) and it took about 2 weeks to get my application published. I basically followed the instructions given on submit Qt applications to the Ovi Store PDF.
The first thing you have to do is to register at Ovi Publish and pay 1 Euro.
You also need to ask for developer certificates and UID in order to be able to publish your application. It took about 48 hours to get the two certificate files (Developer Certificate Key Pair and Developer Certificate Installer) and 10 UID. I applied between Xmas and New Year, it may be even faster during the rest of the year.
After that you need to add the certificate files to your project, configure it to build the smart installer and change the UID in your .pro file.
After that you need to get proj_installer.sis, prepare some screenshots and logo and create a support page/website.
Then you go to Ovi Publish, create Content and follow all the instructions. Most of the time this is straightforward. I selected all countries and all Symbian Anna/Belle smartphones. If for some reasons you need fast approval, you can target specific countries (avoid China) and limit the number of smartphones that need to be tested by QA.
Ovi Publish will inform you of the status of your app after your submission in case a critical part of your app fails QA (My support site failed) and when you app it getting published.
