QUESTION
I tried to add to a ListView
in QML
of N Items
a way to add and delete a new Item
at a given index.
I did the following example, but the problem is that when I move some Items
, when I try to insert a new one, the position might be incorrect and I have no clue why. When I check my DataList
in my cpp model
, positions are correct, however, new or deleted items
won't be inserted
/deleted
at the right position.
It seems that the error occurs when I insert a new Item
, then I move
it , and then I try to delete
this Item
or insert
an Item
next to this New Item
.
Here is a simple example (you can run it if you need). I called my Items Data
: Blocks
ANSWER
Answered 2020-Jan-03 at 22:39There are two bugs when moving items. In DropArea.onEntered
, if you print out both drag.source.visualIndex
and delegateRoot.visualIndex
before and after visualModel.items.move
, you'll see that values are modified after moving. That means you are moving wrong rows when calling myModel.moveBlock
. To fix the problem, save the value before moving items:

I am using EntityFramework code first. Lets say this is my classes:
...ANSWER
Answered 2017-Mar-20 at 21:15The problem is that you can't 'hide' the property virtual BlockModel BlockModel
with the property new virtual ModuleBlockModel BlockModel
because it is technically a different type signature, even though one is a sub-type of the other.
You can try resolving this with generics (they allow the 'type' to be set dynamically), like this:

QUESTION
I have been playing around with the inference module from graph-tool a bit and tried to replicate a section of code from the cookbook section. When running gt.mcmc_equilibrate(state, wait=1000, mcmc_args=dict(niter=10))
I however get an error message.
It seems to revolve around Python argument types not matching C++ signatures. Having done some searching this seems to come up when using different compilers for different modules (?). In this case I am however running the package as downloaded from apt-get
(2.19 (commit da041f33, Sat Nov 12 17:27:48 2016 +0100)) so I was surprised to see it. The same error also gets thrown if running it on a compiled version of the source code (2.20dev (commit 01432d60, Sun Jan 15 19:54:52 2017 +0000)).
Does anybody know what is going wrong here/how I could fix it?
This is the relevant code snippet:
