QVariant: Arrays or list

9il commented 9 years ago

Can you add support for arrays/lists before breaking changes please?

filcuc commented 9 years ago

do you mean QAbstractListModels? currently is still possible even without them

Yes

Take a look at the left side of this diff https://github.com/filcuc/DOtherSide/commit/de533129d21478912c67761260e87dd78bf5c16f?diff=split

Basically you create a QObject with:

an array of QObjects
a Count property of type int that return the array length
add a get slot that return the i-th element
add some functions for add/removing items in the array. Everytime you remove/add an element emit the countChanged signals
in the qml bind the model property of a listView to you QObject count property (in this way you get n-th elements)
in the delegate call your QObject get function with the delegate index

sorry i think that the D implementation lacks of QObject support in slots and signals. I'll push a fix as soon as possible with a working example

Breaking changes is not a problem. I need something to draw charts/plots with hardware acceleration. I hope it can be dqml. But without arrays/lists it is impossible now.

filcuc commented 9 years ago

yep i understand it

This evening i didn't had the time to get completely with dub. In these days i plan to delete the D code from the DOtherSide and continue the development here.

However on the develop branch of the DOtherSide repo you should find an implementation that support the QObject and an example with a list of items.

@9il have you tried my changes?

Hi! I am a little bit miss-oriented. Is QML list implemented like D range of QObjects?

filcuc commented 9 years ago

No, you just expose to QML a QObject with a count property and a get slot. Than QML invoke th get slot that returns a simple type (a double/int/ etc)

Basically the QObject is a Model/Container
