Title:
ListItem calls onClicked handler even when press is cancelled
Status in ubuntu-ui-toolkit package in Ubuntu:
In Progress
Bug description:
To reproduce:
* Run the attached qml file
* press the mouse/finger on the ListItem in the center (don't release)
* drag the mouse/finger outside the listitem
* release
=> you'll see a "Clicked!!!" message printed to stdout
expected: when the user decides not to click an item and cancels it by
moving outside the mouse area to release, the clicked signal should
not be emitted.
This is also what the QML MouseArea does. From it's docs: "A click is
defined as a press followed by a release, both inside the MouseArea
(pressing, moving outside the MouseArea, and then moving back inside
and releasing is also considered a click)."
The current behavior causes some nasty usability issues in some apps
as the user is used to be able to cancel a click this way, but
ListItems behave differently than all the other elements. I.e. the
Ubuntu Button behaves the same as the MouseArea etc.
