** Description changed:
Items outside of a ListView are skipped when using keyboard navigation
to change the focus. However, a ListItem inside a ListView takes the
focus even when it is disabled, but it does not show the focus frame
when focused.
For example, execute this QML program:
import QtQuick 2.4
import Ubuntu.Components 1.3
Item {
width: units.gu(50)
height: units.gu(50)
UbuntuListView {
anchors.fill: parent
delegate: ListItem {
enabled: index != 2
Label {
anchors.centerIn: parent
text: parent.enabled ? "enabled" : "disabled"
}
}
model: 5
}
}
Press TAB to focus on the ListView. Then press the down-cursor-key twice
to move the focus down inside the ListView. The focus will be on the
disabled item, but not focus frame is visible This is confusing for the
user since the focus seems to disappear, and the Item where the focus
seems to be (although invisible) cannot be triggered because it is
disabled.
Note: When fixing this bug, also test the solution for Horizontal
ListViews (and RightToLeft and BottomToTop directions), since I
encountered this bug in the scrolling toolbar (in progress) that has a
Horizontal, RightToLeft ListView.
==========UX Fix===========
- Bypass focus for a disabled item and show focus immediately for the next
- available enabled item.
+ A disabled item should take focus but will not be actionable. The colour
+ of the disabled list item with focus on top will be enough to indicate
+ that it is disabled and focussed. Normal focus behaviour should resume
+ for enabled list items.
