Public bug reported: ubuntu-ui-toolkit r1873
Currently, when creating a list item, the developer has to manually bind the height of the ListItem to that of ListItemLayout that it contains. Since this is not intuitive in QML (you usually bind content's size to parent's, not the opposite), we're seeing that the developers most of the times forget to add that binding. Proof: even the UI Components Gallery was not doing it, and as a result the labels in the list items of the left panel were *slightly* offset. https://code.launchpad.net/~faenil/ubuntu-ui-toolkit/fixListItemAlignmentUIGallery/+merge/287492 If the developer doesn't add that binding, the ListItem usually ends up being shorter in height than the ListItemLayout (or SlotsLayout) it contains. This is usually not a big issue because the deafult ListItem height is enough to show a couple of labels in a column, so the developer will usually not realize that he's done something wrong, but the vertical alignment of the slots will be wrong, because it's computed relative to ListItemLayout's height, not ListItem's (since ListItemLayout resizes dynamically by design to accomodate all the slots). In the worst case (very tall ListItemLayout/SlotsLayout with lots of text), ListItem layout will clip part of the content. My proposal is that we handle this automatically. The developer should not have to care about this detail, because ListItem+ListItemLayout/SlotsLayout is the our main and most important usecase for those components, so it should work straight out of the box and be as simple as possible to implement. My solution (although I only know ListItemLayout/SlotsLayout's code, not ListItem's): - change ListItem so that when a new child is added (content), it checks if that child is a SlotsLayout-derived component. If that is the case, and if that's the only child, then ListItem binds to content's height. NOTE: the solution described above is just a proposal, please make sure that the implementation doesn't prevent the dev from overriding or changing the behaviour if needed. Moreover, I think the binding should not be created automatically if there's more than one child (which I think is then case when using ListItem's "expansion" mode) ** Affects: ubuntu-ui-toolkit (Ubuntu) Importance: High Assignee: Zsombor Egri (zsombi) Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1551349 Title: Make ListItem automatically bind to the height of a SlotsLayout/ListItemLayout when that's the only content To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1551349/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
