Add virtual key handling to InputContext and WaylandIMInputContextV1 #454
Conversation
The current InputContext has the `keyEvent` method, but what it can do is limited. In WaylandIMInputContextV1, key inputs are processed in the `keyCallback` method, but there is no way to pass virtual key inputs to it. This fix adds new methods `virtualKeyEvent` and `virtualKeyEventImpl` to InputContext. By default, it works the same as the existing `keyEvent` method. But `virtualKeyEventImpl` can be overridden by each implementation to define the same behavior as physical keys.

Hi, sorry for not replying this for a while. The key point for me is that, before we move forward we need to have a better design on how it should looks like. For example, "KeyEvent" is solely designed for hardware keyboard. The property on it is not really suitable for virtual key. While the change looks ok on its own, I don't think it fit the big picture, especially virtual key may do things that hardware key can't. I'd suggest we find some time and meet together (maybe also with people that's currently working on fcitx5-android). What do you think?

Thank you for the response! I would appreciate it if there is a proper input method for the virtual keys, We need to figure out in which direction Fcitx5 plans to support virtual key operations in the big picture.
Thank you! |
For a virtual keyboard, we need an interface to convey virtual key inputs to InputContext.
When we were beginning to implement the virtual keyboard, we tried to manage virtual key inputs
using
keyEventandforwardKeyandcommitStringand so on...It was tough to handle them properly on the virtual keyboard side.
It would be nice if we could pass virtual keys to the same logic as physical keys.
In
WaylandIMInputContextV1, key inputs are processed in thekeyCallbackmethod,but there is no way to pass virtual key inputs to it.
This fix adds new methods
virtualKeyEventandvirtualKeyEventImplto InputContext.By default, it works the same as the existing
keyEventmethod,but
virtualKeyEventImplcan be overridden to handle virtual key events.In this fix, core key logic can be shared between physical and virtual key events.
