Well, the title says it all, lets get started :-)<\/p>\n
Something that I would love to see in QML is the QSortFilterProxyModel. I guess it needs a wrapper of some sort, but being able to sort and filter – either based on a role and a regular expression, or based on a JavaScript function would make QML even more powerful.<\/p>\n
Why is this an important feature? To me, the goal of using QML is to put all user-interface specific code in the QML-half of the equation. Adding capabilities to do sorting, and some filtering, to QML reduces the size of the C++ run-time and further decouples the data from how the data is shown.<\/p>\n
A long time ago (pre 4.7.4) I ran into the issue that when resetting a lazy model (i.e. a model implementing canFetchMore \/ fetchMore<\/a>) does not trigger QML to poke at canFetchMore. Very annoying, but sorted in later versions of Qt.<\/p>\n In my experience, QML needs the “::” operator. Binding text to the text from a model using “text: text<\/tt>” does not work. Being able to say “text: ::text<\/tt>“, or “text: data.text<\/tt>” would be nice. Even though the last approach prevents the usage of components with properties named data<\/tt>.<\/p>\n I guess there already might be a way to achieve this, but I’ve not found it. If so, please tell me!<\/p>\n","protected":false},"excerpt":{"rendered":" Well, the title says it all, lets get started :-) Proxy Models Something that I would love to see in QML is the QSortFilterProxyModel.
