Storing plugin data
(too old to reply)

Hi,

I need to store some data for a Qt Creator plugin I am working on.
Keep in mind that I am not talking about settings, but actual data
generated by the plugin.

I am planning to use SQLite to handle the data, but I am not sure where I
should keep the file used to save the database.

Am I supposed to use some data path returned
by QStandardPaths::standardLocations or is there a better/different way for
plugins?

Thanks

SettingsDatabase Class: https://doc-snapshots.qt.io/qtcreator-extending/core-settingsdatabase.html ? Use Core::ICore::settingsDatabase() instance then. If not - create your own SQLite DB and store in QStandardPaths::writableLocation(QStandardPaths::DataLocation) + QStringLiteral("/your_path")

I think I would avoid using ICore::settingsDatabase() if you have much plugin specific data, since it makes it hard to remove data that was created by this plugin and this plugin only. (If you have QSettings-like data, but much of it, you can of course consider using the class Core::SettingsDatabase for your separate data file.)

QStandardPaths has the disadvantage that Qt Creator’s “-settingspath” option will not affect that.
We usually use
Core::ICore::userResourcePath() + “/some_path_that_identifies_the_purpose/“ + filename

Thanks everyone.

It seems Core::ICore::userResourcePath() is what I was looking for.
