It looks good but I don't know if we should return from TextEdit and LineEdit show_virtual_keyboard instead, to avoid showing the virtual keyboard when a physical keyboard is detected, at least we can do it for android and ios only but what if the users still wants to use the virtual keyboard ? There's no option to prefer virtual keyboard over physical one.

@WhalesState Isn't this the current behaviour, virtual keyboard does not appear if physical keyboard is connected.

There was no way to check for physical keyboards before, it was recently merged so it always show the virtual keyboard on android and ios by default.

That's why i have applied a hack for this, since focusing any LineEdit or TextEdit will still show the virtual keyboard even if a hardware keyboard is connected, but I don't know if there are any opened issues or discussions about this.

No, virtual keyboard doesn't appear if physical kb is connected even before that PR . This was used internally just wasn't exposed.

There's an option on android Physical keyboard settings Show on-screen keyboard while a physical keyboard is being used, which is true by default.

I just checked in two different devices and it was turned off in Motorola and turned on in Xiaomi, both are default.
So, yeah the only way to fix this will be to not call show_virtual_keyboard() in lineEdit and textEdit.

But that is out of scope of this PR.
