DearWidgets

DearWidgets aim to produce useful Widgets particulary useful on Graphics (Image Processing, 3D, ...). DearWidgets aim to provide helper to simplify creation of custom widgets.

DearWidgets is 3 collections of helpers:

• DrawLists
• Interactions
• Widgets
• Math Helpers
• Helpers to have type independent "Scalar"

Dear Widgets is a collection of help to simplify the develoment of application.

DearWidgets add some helpers which allow us to create Custom Widget independently of the try. A Scalar is stored as an ImU64, which is a memcpy of any type supported by ImGui {Im{U|S}{8, 16, 32, 64} | bool | float | double}.

• bool IsNegativeScalar
• void EqualScalar
• float ScalarToFloat
• ImU64 FloatToScalar
• ImU64 AddScalar
• ImU64 SubScalar
• ImU64 MulScalar
• ImU64 DivScalar
• ImU64 Normalize01
• ...

DearWidgets is using ImPlatform.

Features

DrawList

• Triangle Pointer {Right, Up, Left, Down}

Used internally for LineSlider

• Hue Band
• Luminance Band
• Saturation Band

Used Internally to implement HueSelector.

• Color Ring

TODO: Ring HueSelector TODO: Add support for 2D (angle, radius) lambda

• Custom Color Ring

• Chromatic Plot{Bilinear, Nearest}
  • Chromatic Point
  • Chromatic Line

• Convex Mask

Support for ConvexMask, will fail or flip triangle if the shape is not convex. In practice some non-convex shape could work if all vertices are visible from the corner of the BoundingBox Used.

• DrawColorDensityPlot (aka ShaderToy)

Use carefully that can have impact on your performances for HighRes canvas or/and expensive lambda.

Widgets

• Hue Selector

Draft

Draft means draft.

Draw

• ChromaticityPlot

Widgets

• DragLengthScalar

• Slider 2D Float A version for Slider2DScaler is available for (Im{S|U}{8,16,32,64}, Float and Double)

• Slider 2D Int

• Range Select 2D

• Slider 3D

• Grid

• 2D Move

• Line Slider (TBD)

Performance Considerations

Notice some DrawList are purely calling DrawList from Dear ImGui. So based on your parameters a non-negligeable impact on performance can be notice. Do not put an unreasonable resolution.

Constrains

C++ features used internally:

• std::string
• (Optionnal) Lambda

Legacy

Removed:

• AnalyticalPlotEx
• AnalyticalPlot
• CenterNextItem
• DragFloatLog
• RangeSelect2D didn't find a proper control
• Slider3D no real use case

Removed C++ feature dependencies:

• template
• constexpr
• if constexpr
• Lambda from template
• auto
• std::vector<float>, std::vector<bool> for isoline
