I know there is already eraser plugin here and there. Im putting it here so i don’t forget - because i want to take a crack on that contentious work flow of the Eraser. Target for this is Krita 6.0 and will utilize the preset tree. [image] Goals: offer simple tip preset brushes at the press of …

I was starting to do the UI. So I decided to do some visualization of what i want to achieve look wise. It be something like this more or less. Things im not yet sure off; the preview. Also i want to try some css styling. [image] Note: This project is mostly for me to learn the new stuff.

What i have so far; I added a size pressure on/off toggle; [image] Now that im looking at it as actual docker. I kinda wanna remove the double spinbox and just make it a full slider.

[image] Progress : Added QLabels with Pixmap. I’m happy that its very close to what I drew. Adjustment still need to be made to make sure the images will fit the boxes. I’m still trying to get .scale of qpixmap to size. I might need to run a ration calculation or something. For now i hope i can…

[image] Update - this is close to the final ui. Though im still debating between using scene directly or grabbing pixmap. I have issue triggering the QGraphicsView to update even if brush editor is hidden. I do remember years ago having similar issue with early version of CBT. welp. I forgot wha…

I had little fun with QTabletEvents and krita.Scratchpad, maybe it can be used as alternative way to show preview? import math from krita import Krita, Scratchpad from PyQt5.QtCore import Qt, QPointF, QEvent from PyQt5.QtGui import QColor, QTabletEvent, QPainterPath from PyQt5.QtWidgets import QApp…

Thank you for this. as for what i have so far. I do manage to get it to update if the brush editor docker is open. It perfectly mirrors it to my own graphics scene. It seems that i’m missing something, or that the previewer is probably not running/updating if the editor is close.

I have read on it a little. it says i need to use QGraphicsView::render Or atleast call and pass on a Qpainter for it to pain while docker is closed. i have not successfully done that.
