Bug ID: 422045
Summary: Advanced Colour Selector does not respond properly to
HSV keyboard shortcuts shifts in some situations
Product: krita
Version: unspecified
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Usability
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
This happens with all versions from 4.2.9 to the 22-May 5.0.0 prealpha (git
fdf794d)
This is a minor bug and is confusing until you realise what you need to do to
avoid it.
It's only present for the Advanced Colour Selector, not any of the other colour
selector dockers.
It happens with all wheel/rectangle presentations and all colour model types.
It seems to happen with all bit depths and colour spaces but I haven't done
full coverage of all possible variations.
It happens whether the Advanced Colour Selector is docked or floating.
It's not likely to be noticed in general but the behaviour is different from
all the other types of colour selection/modification dockers.
If you click to select a hue or a saturation/value, then use a keyboard
shortcut to darken/lighten or to do a hue shift, the new value or hue is not
shown on the wheel/rectangle unless you do this with the cursor placed outside
of the active docker area.
If you do e.g. 'K' for darken then successive presses are 'stored' and then the
cumulative effect is shown after you do a 'K' with the cursor outside of the
active docker area.
While these not-displayed 'K' shifts are being done, the changes are shown on
the other colour selector dockers an also on the Shade Selector of the Advanced
Colour Selector.
STEPS TO REPRODUCE
1. Select a hue or saturation/value by clicking in the Advanced Colour Selector
and keep the cursor within the rectangular area that encloses the colour wheel
(including just outside the hue ring).
2. Press 'K' to darken the colour
[Note that the selected point of saturation/value does not change but the shade
selector display does change and any other colour selector dockers show the
change.]
3. Press 'K' again.
[Note the same result as in 2.]
4. Move the cursor outside of the selection area to any of: shade selector,
colour history area, the tab label of the Advanced Colour Selector itself, any
other docker or the workspace.
5. Press 'K' again.
[Note that the Advanced Colour Selector now shows the cumulative effect of
three 'K' presses.
OBSERVED RESULT
See Steps To Reproduce
EXPECTED RESULT
The change due to use of the keyboard shortcuts should be immediately seen on
the colour display of the Advanced Colour Selector without needing to move the
cursor away from the HSV selection zone.
