Planned maintenance has been done but it did not solve the problem. So work will continue on this and a new time for trying updates will be announced asap.
cache Buffer in ListView works only in one direction?
-
Hi together!
I developed a customized Scroll-Bar for ListViews, which is using the contentY / contentHeight / originY Properties.
The ListView has cacheBuffer enabled, but the buffering works - via setting contentY property - only in one direction. When the new contentY value is higher than the old one (down scrolling), i can follow the creation of delegates outside the visible viewport area via debug messages. But if i scroll upwards (setting a lower contentY value as before) then no Delegates will be prealoaded.
In consequence, my ListView can scrolling down nice and fluid but upscrolling is really juddery (low performance arm devicer).If i use the flick gesture to scroll, the preloading works perfectly in both directions. But in this case, the interactive property has to be set to false.
So: Is there any other property as contentY to scroll the content of a ListView manually? Any suggestions or proposals are welcome!
Thanks in advance,
Frime

Hi @Frime,
Can you post a minimal compilable example which will show the problem ?
