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.

@knimitz 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:
