Title:
  Mir-backed InputDeviceModel’s count property is not updated timely

Status in qtsystems-opensource-src package in Ubuntu:
  Fix Released

Bug description:
  I’m trying to use InputDeviceModel from QML with the following
  example:

  import QtQuick 2.4
  import QtSystemInfo 5.5
  Item {
InputDeviceModel {
  id: idm
  filter: InputInfo.Mouse
  onCountChanged: console.log("mice model count:", devices, count)
  onAdded: console.log("added mouse:", inputDevice, count)
  onRemoved: console.log("removed mouse:", deviceId, count)
}
readonly property bool hasMouse: idm.count > 0
onHasMouseChanged: console.log("has mouse:", hasMouse)
  }

  When I launch the example with qmlscene on my arale with no mouse
  connected, I’m not seeing any output (expected).

  Then I connect a bluetooth keyboard/mouse combo, and I’m seeing the following:
mice model count: 1 0
added mouse: QInputDevice(0x17f6298) 1
(note how 'hasMouse', which supposedly was initially false, hasn’t been 
updated)

  Then I disconnect the combo, and I’m seeing the following:
mice model count: 0 1
has mouse: true
removed mouse: 15 0

  Then I connect it again, and I’m seeing the following:
mice model count: 1 0
has mouse: false
added mouse: QInputDevice(0x18ee508) 1

  It appears the countChanged property is emitted before a device is
  added to/removed from the model, and thus the row count hasn’t
  actually been updated yet. So any property binding that relies on
  'count' will have an incorrect value.

Can you test the ticket? It would be ready for xenial (overlay) and

[Olivier Tilloy]

I guess an easy fix would be to emit countChanged again when a device is
added to/removed from the model. A (probably) better approach would be
to not emit countChanged until after the model has been updated.

  actually been updated yet. So any property binding that relies on
  'count' will have an incorrect value.
