Unicode code point via number pad?

[malonn23]

I noticed that Unicode input does not work via the numpad. Is this a code limitation or a configuration thing? Just curious.

FeatherPad supports what Qt does. If, at some point, Qt supports Unicode input with numpad, it'll show up in FeatherPad automatically.

I might add codes to FeatherPad for supporting it in its text view — I think it'll be a good feature — but other text entries (like line-edits) depend on Qt itself.

No problem, brother. I admit that I have not looked at the source (don't know much C++), but I do know (as do you, apparently) that numpad support is present in Qt. It may require an QKeyEvent, i.e. it is not present in the QLineEdit widget (without sub-classing it, of course) by default. Whatever you decide to do, I love your application. My favorite text editor to date.

With Qt and C++ you can do many things :) Actually, FeatherPad's code is full of examples, some of which work around Qt bugs. The question is, "will it be worth the additional code?" I think, in this case, it might. But I need to get my hands dirty to know for sure.

OK, this is a relatively complete answer (which I found years ago but forgot later):

To support unicode input with all Qt apps, the user needs to install ibus, (auto-)start ibus-daemon, and set the environment variable QT_IM_MODULE to ibus. Then all Qt apps accept Ctrl+Shift+U + unicode + Space/Enter.

GTK supports Ctrl+Shift+U without needing ibus.

BTW, the numbers can be written in any way; number pad isn't important.
