SUMMARY The hit boxes when editing curve vertices in, for example, the Color Adjustment Filter are far too small. I'm constantly creating new points where I don't want them. I can see two possibly causes: either the hitboxes are genuinely too small, or they aren't taking DPI into account on Windows (or possibly both). SOFTWARE/OS VERSIONS Windows: 11
Created attachment 147388 [details] Shows scaled handles It's not that the handles don't scale: if I use QT_SCALING_FACTOR=2 krita, then open the adjustment filter, the handles clearly are scaled. The question is... Is this something that was improved since 4.8, or not. Tiar did a lot of work improving scaled display painting.
Hm, Windragon says that the problem probably not is in the rendering... I'll have to look into this a bit more.
Git commit d28aaccfdcc364447583803968f3d4bd9692708c by Agata Cacko. Committed on 02/04/2022 at 00:50. Pushed by tymond into branch 'master'. Fix too small hitboxes for curve widget Before this commit, it was difficult to click on a control point of the curve widget, especially with a stylus, because the hitboxes were quite small. Some time ago the control boxes were made visually bigger, but without taking care of hitboxes, so the situation just before this commit was that the user could click on the ellipse marking the control point but still create a new point instead of moving the one the user intended to click on. This commit ensures that the painting code and the logic code both use the same value, and that the hitbox for the point is circular.
