Issue: Mac OS + International Keyboards
Unsolved
General and Desktop
-
Seem to be having an issue with International Keyboards on MacOS and I apologize if there is a more specific forum but as you can see by my post count I am new here (I did do a search and could not find anything related to my issue).
Specifically, we are attempting to process a QKeyEvent with code that looks something like:
somefuntion(QKeyEvent* event) {
int ourKeyCode = mapQTToUs(event->key());
}Where the function mapQTToUs() is just a big switch statement that uses the enum Qt:Key to map QT codes to ours. On Windows (with any keyboard) or with standard keyboards on MacOS everything works fine. However, with some international keyboards (such as PC-German) on MacOS the Qt:Key that we seem to be passed by the QKeyEvent is often Qt::Key_unknown?
This would seem to indicate to me that Qt does not support that keyboard on MacOS? Is this true? Or is this a configuration issue on our part? I realize this is a very specific question and I have provided little detail but I am hoping this is a common issue that someone might recognize before I go into a ton of detail?

Hi,
Is it a hardware related problem ? Or any keyboard that you set to German triggers that ?
-
Good question, it is not hardware related but after more investigation it is specific to the keyboard layout. Apparently the user in question has a user defined layout (ie not from Apple) to make braces { [] } work.
I should have also mentioned, it is not all keys. For the most part, the keyboard works fine. It is certain combinations (like Alt-L for example) that cause the issue.

Can you have more details about how he did that custom layout ? And what keys exactly are misbehaving ?
-
The layout was created using Ukelele version 2.2.8 (Unicode Keyboard Layout Editor). He has said there are several keys that do not work but specifically he says "Alt + l" produces Qt::Key_unknown.
His pc.keylayout config file (which is found in ~/Library/Keyboard Layouts/) looks like....
