# Feature: Add analogue gauges (#4656) ## Summary Adds circular, linear, and rectangular analogue gauges to `Krypton.Gauges` with a shared value/range/palette model, optional animation, and optional interactive input so dashboard-style control panels can use a matched set of indicators. ## Related issues - Closes #4656 ## Type of change - [x] Feature / enhancement (`Implemented`) ## Changes - `Krypton.Gauges`: shared `KryptonGaugeBase`, `GaugeValues` / face subclasses, `GaugeRange` collection, `PaletteGauge*` colours - New toolbox controls: `KryptonCircularGauge`, `KryptonLinearGauge`, `KryptonRectangularGauge` with designers / action lists dual-compiled into `Krypton.Gauges.Design` - TestForm: `KryptonAnalogueGaugeDemo` registered in `StartScreen` - Standard-Toolkit-Demos: `KryptonAnalogueGauge Examples` on branch `alpha-4656-analogue-gauges` (worktree `Standard-Toolkit-Demos-4656`; main Demos tree had unrelated WIP) ## Affected packages & target frameworks - Packages: `Krypton.Gauges` / `Krypton.Gauges.Design` (via `Krypton.Standard.Toolkit`) - TFMs verified: suite Debug build (`net472`, `net48`, `net481`, `net10.0-windows`, `net11.0-windows`) ## Validation - TestForm demo: `KryptonAnalogueGaugeDemo` (StartScreen: “Analogue Gauges (#4656)”). - Manual steps: 1. Open the demo; confirm circular / linear / rectangular / segmented faces share warning/error ranges. 2. Drag the trackbar; indicators ease when Animate is on. 3. Enable Interactive (or drag the dedicated interactive circular gauge); pointer and keyboard change `Value`. 4. Use the property-grid selection buttons to inspect `Values` / `State###`. - Demos: `Krypton Analogue Gauge Examples` on `alpha-4656-analogue-gauges`. - Build: `dotnet build ".\Source\Krypton Components\Krypton Toolkit Suite 2022 - VS2022.sln" -c Debug` ## Screenshots / GIFs ## Changelog - Entry added to `Documents/Changelog/Changelog.md`: ```markdown - Implemented [#4656](#4656), Analogue gauges in `Krypton.Gauges`: circular needle, linear bar, and rectangular (solid or segmented) indicators that share value/range/palette settings, optional animation, and optional interactive input. Included in the [Krypton.Standard.Toolkit](https://www.nuget.org/packages/Krypton.Standard.Toolkit) package. ``` ## Breaking changes & migration None. ## Developer documentation - `Documents/Development/Krypton-Analogue-Gauges.md` (local; not for the PR) ## Build log ## Checklist - [x] Builds for `net472` and is C# 7.3 compatible where required - [x] New compiler/analyzer warnings in touched code addressed - [x] `Documents/Changelog/Changelog.md` updated - [x] TestForm demo added or updated (features / observable bug fixes) - [x] `Documents/Development/` guide added (substantial features) - [x] Screenshots/GIFs included (UI changes) - [x] Build log screenshot included - [x] Breaking-change impact and TFM notes documented above

Add thermometer and AC/DC ampere-meter controls with configurable scales, ranges, input, rendering, and designer support. Extend the analogue gauge demo and update the changelog.

Would like too see what this looks like in the Dark Themes before allowing it through (i.e. there are still a lot of controls that do not work correctly in the "dark"!!) |

create an onging ticket .... i would say... |
Update screenshot guidance and the PR template to require light and dark captures for UI changes. Extend the analogue gauge screenshot script and its documentation to produce both palette variants.

There was a problem hiding this comment.
Thanks for the images,
Just noticed: Why is the text in the buttons not fully central On the vertical axis ?
