Before posting
- Get familiar with Markdown to format and structure your post
- Be sure to update lvgl from the latest version from the
masterbranch.- Be sure you have checked the relevant part of the documentation. We will not respond in detail to posts where you haven’t read the relevant documentation.
- If applicable use the Simulator to eliminate hardware related issues.
Delete this section if you read and applied the mentioned points.
Description
What MCU/Processor/Board and compiler are you using?
visual studio 2017
What LVGL version are you using?
v7
What do you want to achieve?
how to overcome roller events influence each other
What have you tried so far?
Change the roller style and some other property
Code to reproduce
Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.
The code block(s) should be formatted like:
/*You code here*/

## Screenshot and/or video
If possible, add screenshots and/or videos about the current state.
I build three roller and each of them has an event,but
when I rolling one of them with no stop exactly on an option and at this time rolling another,the previous even move.
