Dear Roger, In this particular situation Oxygen offers in that dialog that asks you what editor should be used to open the ".h" file an option that says: [ ] Associate file type with editor If you want to always open ".h" files with the C editor, just enable the checkbox and this will automatically add an entry in Options->Preferences -- File Types that will associate for the ".h" extension the C editor. We considered this to cover the use case you mentioned, and if somebody does not want to enable this checkbox then maybe they want to have the option to select another editor next time a ".h" file is opened. You may also go to the "File types" preferences page and associate there extensions with specific editors. There are some cases when we apply the idea of learning, for example if you open a file without any schema, then Oxygen will automatically infer the document structure from the current file and it will offer content completion based on that.

Hi Folks,

I am using Oxygen to create C programs. I drag and drop a .c file into Oxygen and Oxygen recognizes that it should use its C editor to open the file. I drag and drop a .h file into Oxygen and Oxygen asks me what kind of file it is. I can drag and drop the .h file into Oxygen a hundred times and Oxygen will always ask me what kind of file it is, and I always tell Oxygen the same thing. Why can't Oxygen learn? After some number of times telling Oxygen to use the C editor, Oxygen should assume that the .h file should be opened using the C editor.

Well, that is on my wish list for Oxygen.
