ivi-input-controller causes qtvirtualkeyboardplugin to fail emit keystokes

qtvirtualkeyboard is GPLv3 only, and also only a static library. So likely can't be used as is

I'm sorry, I lectured about how to attach files to JIRA ticket, then pushed test png accidentally.

There some new png that suppose to be in the attachments?

Good log. Refer to the log, I probably found the root cause.

According to https://www.toradex.com/community/questions/9687/qt5-input-method-is-not-set.html, I thought this is the same issue. So, the root cause is the surface doesn't get focus of keyboard.

When I did the following command, keystroke appears on textbox on my side.

LayerManagerControl set surface 2 input acceptance to default
LayerManagerControl set surfaces 2 input focus keyboard

I assume surface id of settings application is 2.

Then qt.virtualkeyboard seems to get inputMethod. Below is the log after setting focus.

ivi-input-controller doesn't attach all focus of events to the top application automatically. (touch event is automatically attached). If ivi-input-controller is necessary, HMI controller such like window manager should implements controlling ivi-input-controller. Currently, Window manager doesn't implement ivi-input management.

So ivi-input-controller.so should not be enabled for now, IMHO.

Turned on debugging and there is clearly something going on in the background that is likely due to ivi-input-controller taking the focus

With ivi-input-controller.so disabled:
