Why the first one should be able to do File I/O and the second one not? Why running in the panel is less secure than running in a window? On the other hand, I don't see any advantage in having to add C++ to do file I/O. A plasmoid isn't more secure if I do file I/O with C++ than if I could do file I/O with a QML library. I only see disadvantages in the C++ option: - The developer will have to learn C++. - The developer will have to learn how to communicate QML with C++. - The developer will have to compile the plasmoid for each distribution/architecture. Or the user will have to download the source code and compile it. > Perhaps you could tell us about your exact use case, maybe we're able to > suggest a better solution than to offer a generic file I/O API.

I can only say that it requires to read and write from/to files in disk, it is a core feature.

I'm very reluctant to add generic file I/O to our QML API, as that is going to make it very hard to secure it later on. We haven't redone the file I/O portions for that reason. Perhaps you could tell us about your exact use case, maybe we're able to suggest a better solution than to offer a generic file I/O API.

[Plasmoids] Can I write to file from a pure QML plasmoid?
Hi. One week ago I asked a question at forum.kde.org, but nobody responded, so I'm now trying here in the mail list, please redirect me to the appropiate list if this one is not the correct one. I'm copying the question... Hi, I'm creating a QML plasmoid that will write data to a file in disk. I have searched a lot, and it seems that it is not possible with a pure QML plasmoid. Web pages say that the only way to do it is by adding C++. The problem with adding C++ is that, as I understand, the plasmoid will have to be compiled, so I will get some binary files that won't work in all Linux distributions. In other words, the plasmoid will be less portable: I will have to create a different file for each Linux distribution before posting the plasmoid to kde-apps.org, or the user will have to download the source code and compile it for his/her distribution. It is a mess. I think that file I/O should be possible from a pure QML plasmoid. It is a core functionality for a high percentage of plasmoids. If you make it difficult (by requiring the C++ mess), less programmers will create plasmoids, so less plasmoids will be created. In fact, file I/O was possible in kde4 from a pure javascript plasmoid, by using the "Local IO" library: https://techbase.kde.org/Development/Tutorials/Plasma4/JavaScript/API-LocalIO I really would like to listen that file I/O is possible from a pure QML plasmoid in kde5. Or at least that developers are already working on a kde library to make it possible.
