Solved setContextProperty takes very long and blocks UI
-
Hey,
I am calling "setContextProperty" with a bigger data structure. It is not extremely big (A list with about 100 entries), but it takes several seconds until the call finished.
AND because I have to do that in the main thread, the complete UI is blocked in that time. So what can I do?
Thanks!

Hey,
I discovered: It is not setting the data itself. It is the UI structure, that displays the data that takes so long. So I tried disabling the UI Display (It is a ListView) by setting its model to
[]
while I am loading. But now, re-enabling the UI Display takes long.What can I do?

Hi,
What kind of list is ?
-
It is a list of QObjects, which themself each contain a list of QObjects. But I found the error!
The code was like this (pseudo code):
ListView { model: cppData delegate: ListView { model: innerData delegate: Item { Rectangle {...} DropShadow { ... visible: isActiveObject } } } }
So I was creating a lot of DropShadows. Also only one was visible, that was the problem. Removing the DropShadows solved it.
