[Qt-interest] Defining large QMap

[Malyushytsky, Alex]

You can save it in any format you want and add this file to resources, then read from it the same way you read  icons.
It is handled by QFile automatically, you can refer to the resource paths instead of ordinary file system paths.

P.S. Personally I would not recommend such approach for storing static data cause it requires additional application to write such binary file and this application still need to get this data somewhere.

Regards,
   Alex

Hello Andre,
Thanks for reply. I am using a similier approach, but I don't want to give that ASCII file to user of software. Is there a way to have it as a Binary file?
How is the method you say about using resourse file? I use that for images and icons but never for Maps.

Thanks
Yogesh Upreti

Basically, yes, you have to do it one by one. However, you don't need to
put a huge hardcoded list of QMap::insert statements in your code, of
course. I usually use a file with the data, either compiled in as a
resource or externally, and load that in. You could even use a
QDataStream to load the whole map in one go, but that means making sure
that your input data is in the right format.
