[Bug 1638517] Re: Mir-backed InputDeviceModel doesn’t work on touch device
How about not passing any argument to the signal emission? AFAIK, a lot of Qt *Changed signals don’t take any argument, so that would be in line with existing code. Of course we’d need to verify that by the time the signal is emitted the row count has actually changed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638517 Title: Mir-backed InputDeviceModel doesn’t work on touch device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtsystems-opensource-src/+bug/1638517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1638517] Re: Mir-backed InputDeviceModel doesn’t work on touch device
I seem to remember @timo-jyrinki suggesting the 'devices' name at review time, so I must have not changed the base class. Not sure which one makes more sense. Suggestions?

[Bug 1638517] Re: Mir-backed InputDeviceModel doesn’t work on touch device
Nice catch Lorn! This is a nasty one. I would have expected that the
value of the count property would be updated *before* the countChanged
signal is emitted, regardless of the name of the parameter of the
signal.
So I just verified that if I do that, this works:
import QtQuick 2.4
import QtSystemInfo 5.5
Item {
InputDeviceModel {
filter: InputInfo.Keyboard
onCountChanged: console.log("keyboard count:", devices)
}
}
However I’m wary of using that just yet, in case you decide to change
the name of the parameter to 'count', my code would break. Please let me
know if you plan to do so, and I’ll just hold off.
Also, the warning about object ownership and threads is still present. I
think it should be investigated, as it’s usually a good indicator that
something is not architected correctly.

[Bug 1638517] Re: Mir-backed InputDeviceModel doesn’t work on touch device
@osomon The reason you are seeing this not work correctly, is because the value for countChanged signal is named 'devices' in the declarative class, and not 'count' like what is in the base class and that you are using in your qml example. This should probably get changed in the declarative class to match the base class. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638517 Title: Mir-backed InputDeviceModel doesn’t work on touch device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtsystems-opensource-src/+bug/1638517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1638517] Re: Mir-backed InputDeviceModel doesn’t work on touch device
Got this working on my laptop w/ unity8... Except it does work, still see that thread message, except the count is opposite of what it should be. When I disconnect the keyboard (usb as well as bt) it says count: 2, and when I connect it count: 1 When I first run the test qml, it reports count: 0 when it should report 1, as the laptop has a keyboard. The first time I connect a keyboard there is no report, or when I first disconnect it. Subsequent connection I see count: 1 (should be 2) ... So it does seem to work regardless of the thread message, just not as it should. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638517 Title: Mir-backed InputDeviceModel doesn’t work on touch device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtsystems-opensource-src/+bug/1638517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Lorn: no need for webbrowser-app, the issue can be reliably reproduced with the standalone QML example in comment #1.

[Bug 1638517] Re: Mir-backed InputDeviceModel doesn’t work on touch device
I tested this in bug #1536669 on krillin and Unity 8 desktop on
Chromebook, and it worked fine with the example apps, the QML of which
called:
InputDeviceModel {
id: deviceModel
filter: InputInfo.Keyboard | InputInfo.Mouse | InputInfo.TouchScreen
onCountChanged: {
console.log("new count of filtered devices: " + devices)
}
}
It doesn't say it there but I believe I did test with my Bluetooth mouse
too. But maybe indeed there's some case either arale specific or related
to the mouse+keyboard combo.
