Unsolved Dynamic height for card/rectangle used as ListView delegate
-
Hi, long-time web dev here, building a native app for desktop for the first time on QT/QT Creator. Been learning QT/QML for a day, and I've got this far, but I need help.
I'm building an a fairly simple interface to my design, where in I have a list view whose delegate is a custom component which in itself is a card that display a bunch of information about a gitlab issue. This issue (its text and content are completely dynamic)
Here is an example a card. Every part marked with a red square can have a variable height either due to:
- text length
- tab content varying in height: (i.e.
listtab is just a set of icons,assigneeis a set of assignees and labels, andestimateis a simple number entry
The problem I've having is the layout of the cards. I'm trying to use the
RoyLayoutandColumnLayouttypes, because I know they have their own intrinsic heights calculated from children. This is important to me, because, and this is really important I don't want to have to specify explicit heights for any of the content. I want the cards to be as compact as possible and grow with their content, including the internal card menu, which is only visible if the card is selected.I'm almost there, but I just can't quite get some of the margins correct (especially on the bottom margin) which seems to be be flush against the bottom of the card, and in fact, despite being invisible, seems to be reserving space for the hidden buttons:
ListView

Font.Bold : Font.Normal horizontalAlignment: Text.AlignHCenter verticalAlignment: Text.AlignVCenter } } } } } } }Resulting render:
How can I fix these things?
- There is too much space on the bottom side of the card
- The buttons overflow the box, and the border
- there is no padding on the box on the top side
Any help would be appreciated

Solved it for those who care. Had to jump through some hoops:
Task Card
