[SailfishDevel] Silica QML objects that can have a menu property

Unfortunately Silica doesn't have convenience API for adding a context menu to any item as it needs to make sure the surrounding view layout makes room for the opening menu and that the menu is positioned correctly in relation to display. So far adding menus for anything other than a list item has been a unnecessarily painful.

We now finally got around developing GridItem, which provides menus and remorses like ListItem, but takes care of the different positioning rules of a grid. GridItem works with Grid and SilicaGridView. We are targeting to get the new component out with 3.2.1.

Note GridItem does not work in vanilla GridView, we need to do some adjustments to workaround GridView limitation that assumes each grid delegate has the same dimensions. I hope some day Qt gains more sophisticated views, which allow aggregating content from multiple models, supports dynamically sized grid items, more natural stacking flows, and so on.

Br,

Joona Petrell

Hi Thomas,

Thanks for your long answer and the many references, I guess my main point was a bit nit-picking in the sense that Semantically/Linguistically it does not seem to make sense to me to use a ListItem (yes it works, but if you were to tell anyone that is what you need to use I think they would also say "huh?")

Container and Item and are not documented here: https://sailfishos.org/develop/docs/silica/sailfish-silica-all.html/
To me using Item or Container for this would make most sense actually.

Thanks again for your time,
Eli

You can set the 'container' property to the parent of the menu as done in:
https://github.com/tanghus/kitchen-timer-qml/blob/master/qml/pages/TimerPage.qml#L220

There it's a BackgroundItem:
https://github.com/tanghus/kitchen-timer-qml/blob/master/qml/pages/TimerPage.qml#L124

Or did I misunderstand you?
