Unity 8 doesnt respect Qt::CursorShape

[Dubstar_04]

Unity 8 doesn't respect the cursor shape and the cursor remains a standard Qt::ArrowCursor regardless of what it is set to.

Status changed to 'Confirmed' because the bug affects multiple users.

Works on my laptop.

[Daniel d'Andrada (dandrader)]

Please provide details and a sample application

[Daniel d'Andrada (dandrader)]

for testing, I used CursorShapes.qml from lp:~dandrader/+junk/animatedDemos
(if you wanna try that you'll have to build the CustomCursor module there and make QML2_IMPORT_PATH point to it

This is a copy of the code from the mouse area:

           MouseArea {
                id: mouseArea
                anchors.fill:parent

                hoverEnabled: true
                cursorShape: Qt.CrossCursor
}

The Apps were built with "framework": "ubuntu-sdk-15.04" which framework are you using?

That isn't enough. MouseArea.cursorShape is subject to interference from
overlapping MouseAreas etc. Nothing guarantees you it will be reflected
on the QWindow::cursor() of your application, which is what the shell
(Unity 8) sees. So it depends on the scene as a whole.

That test app I pointed you to uses just plain Qt/QML. There's no Ubuntu
Ui Toolkit in there.

My guess is that the bug is either in the application code or in the
toolkit used by it.

Check if you QWindow::cursor() also changes to a Qt.CrossCursor.

[Dubstar_04 (dubstar-04)]

The app works as expected in Unity 7 when testing. The cursor is set depending on the current action and switches as expected.

On unity 8 I only have a Qt::ArrowCursor shown.

I do have the mouseArea wrapped in a MultiPointTouchArea. Maybe the MultiPointTouchArea is handled differently on unity 7 because there is no touch device.

I will remove the MultiPointTouchArea and test and feedback.

Thanks,

Dan

If you still find it doesn't work, then that's bug 1447839.

Although our toolkits do tell Mir what the current cursor is as it moves over the window, Unity8 is the one shell that doesn't yet implement that in-window cursor changing. There's a trivial test case for it in bug 1447839.

[Daniel d'Andrada (dandrader)]

Unity8 does implement "in-window cursor changing". If by that you mean a client application setting the cursor of its surface and unity8 taking that info a using it.
