How to avoid creating too many similar widgets

[manto.1]

I am makeing a gauge background out of many circle widgets. I dont want to use static immage background because the position of segments can change depending on the maximum rpm.

I have create this in TouchGFX designer and for each circle widget Designer created also a painter. Therefor there are many painter that have the same color configuration. Is it possible to eliminate some widgets and/or painters to reduce the memory consumption.

Hello manto.1,

Unfortunately there's not too many option. The only thing that you can maybe try is to do a half of your image and try to do a "mirroring" on it. It should be possible with an AbstractPainter but I never tried it. But I'm not sure if you'll always have a symmetry on your gauge, if not, this solution will not work.

Else I don't see other solution than changing your scale instead of changing the position of your segments, or use a static image background.
