+# Contributing to this repository
+
+This repository seeks to accumulate Qt-based widgets for python (PyQt & PySide)
+that are not provided in the native QtWidgets module.
+
+## Clone
+
+To get started fork this repository, and clone your fork:
+
+```bash
+# clone your fork
+git clone https://github.com/<your_organization>/superqt
+cd superqt
+
+# install pre-commit hooks
+pre-commit install
+
+# install in editable mode
+pip install -e .[dev]
+
+# run tests & make sure everything is working!
+pytest
+```
+
+## Targeted platforms
+
+All widgets must be well-tested, and should work on:
+
+- Python 3.7 and above
+- PyQt5 (5.11 and above) & PyQt6
+- PySide2 (5.11 and above) & PySide6
+- macOS, Windows, & Linux
+
+Until [qtpy](https://github.com/spyder-ide/qtpy) supports PyQt6/PySide6, imports
+should use (and modify if necessary) `superqt.qtcompat`.
+
+## Style Guide
+
+All widgets should try to match the native Qt API as much as possible:
+
+- Methods should use `camelCase` naming.
+- Getters/setters use the `attribute()/setAttribute()` pattern.
+- Private methods should use `_camelCaseNaming`.
+- `__init__` methods should be like Qt constructors, meaning they often don't
+  include parameters for most of the widgets properties.
+- When possible, widgets should inherit from the most similar native widget
+  available. It should strictly match the Qt API where it exists, and attempt to
+  cover as much of the native API as possible; this includes properties, public
+  functions, signals, and public slots.
+
+## Testing
+
+Tests can be run in the current environment with `pytest`.  Or, to run tests
+against all supported python & Qt versions, run `tox`.

-**The missing multi-handle range slider widget for PyQt & PySide**
+###  "missing" widgets and components for PyQt/PySide

-![slider](images/slider.png)
+This repository aims to provide high-quality community-contributed Qt widgets and components for PyQt & PySide
+that are not provided in the native QtWidgets module.

-The goal of this package is to provide a Range Slider (a slider with 2 or more
-handles) that feels as "native" as possible.  Styles should match the OS by
-default, and the slider should behave like a standard
-[`QSlider`](https://doc.qt.io/qt-5/qslider.html)... but with multiple handles!
+Components are tested on:

- `QRangeSlider` inherits from [`QSlider`](https://doc.qt.io/qt-5/qslider.html)
-  and attempts to match the Qt API as closely as possible
- Uses platform-specific styles (for handle, groove, & ticks) but also supports
-  QSS style sheets.
- Supports mouse wheel and keypress (soon) events
- Supports PyQt5, PyQt6, PySide2 and PySide6
- Supports more than 2 handles (e.g. `slider.setValue([0, 10, 60, 80])`)
+- macOS, Windows, & Linux
+- Python 3.7 and above
+- PyQt5 (5.11 and above) & PyQt6
+- PySide2 (5.11 and above) & PySide6

-## Installation
+## Widgets

-You can install `QtRangeSlider` via pip:
+Widgets include:

-```sh
-pip install qtrangeslider
+- [Float Slider](docs/sliders.md#float-slider)

-# NOTE: you must also install a Qt Backend.
-# PyQt5, PySide2, PyQt6, and PySide6 are supported
-# As a convenience you can install them as extras:
-pip install qtrangeslider[pyqt5]
-```
+- [Range Slider](docs/sliders.md#range-slider) (multi-handle slider)

+<img src="https://raw.githubusercontent.com/napari/superqt/main/docs/images/demo_darwin10.png" alt="range sliders" width=680>

------

-## API
+- [Labeled Sliders](docs/sliders.md#labeled-sliders) (sliders with linked
+  spinboxes)

-To create a slider:
+<img src="https://raw.githubusercontent.com/napari/superqt/main/docs/images/labeled_qslider.png" alt="range sliders" width=680>

-```python
-from qtrangeslider import QRangeSlider
+<img src="https://raw.githubusercontent.com/napari/superqt/main/docs/images/labeled_range.png" alt="range sliders" width=680>

-# as usual:
-# you must create a QApplication before create a widget.
-range_slider = QRangeSlider()
-```
+- Unbound Integer SpinBox (backed by python `int`)

-As `QRangeSlider` inherits from `QtWidgets.QSlider`, you can use all of the
-same methods available in the [QSlider API](https://doc.qt.io/qt-5/qslider.html).  The major difference is that `value` and `sliderPosition` are reimplemented as `tuples` of `int` (where the length of the tuple is equal to the number of handles in the slider.)
+## Contributing

-### `value: Tuple[int, ...]`
+We welcome contributions!

-This property holds the current value of all handles in the slider.
-
-The slider forces all values to be within the legal range:
-`minimum <= value <= maximum`.
-
-Changing the value also changes the sliderPosition.
-
-##### Access Functions:
-
-```python
-range_slider.value() -> Tuple[int, ...]
-```
-
-```python
-range_slider.setValue(val: Sequence[int]) -> None
-```
-
-##### Notifier Signal:
-
-```python
-valueChanged(Tuple[int, ...])
-```
-
-### `sliderPosition: Tuple[int, ...]`
-
-This property holds the current slider positions.  It is a `tuple` with length equal to the number of handles.
-
-If [tracking](https://doc.qt.io/qt-5/qabstractslider.html#tracking-prop) is enabled (the default), this is identical to [`value`](#value--tupleint-).
-
-##### Access Functions:
-
-```python
-range_slider.sliderPosition() -> Tuple[int, ...]
-```
-
-```python
-range_slider.setSliderPosition(val: Sequence[int]) -> None
-```
-
-##### Notifier Signal:
-
-```python
-sliderMoved(Tuple[int, ...])
-```
-
-### Additional properties
-
-These options are in addition to the Qt QSlider API, and control the behavior of the bar between handles.

-## Examples
-
-These screenshots show `QRangeSlider` (multiple handles) next to the native `QSlider`
-(single handle). With no styles applied, `QRangeSlider` will match the native OS
-style of `QSlider` – with or without tick marks.  When styles have been applied
-using [Qt Style Sheets](https://doc.qt.io/qt-5/stylesheet-reference.html), then
-`QRangeSlider` will inherit any styles applied to `QSlider` (since it inherits
-from QSlider).  If you'd like to style `QRangeSlider` differently than `QSlider`,
-then you can also target it directly in your style sheet.  The one "special"
-property for QRangeSlider is `qproperty-barColor`, which sets the color of the
-bar between the handles.

-## Labeled Sliders
-
-This package also includes two "labeled" slider variants. One for `QRangeSlider`, and one for the native `QSlider`:
-
-### `QLabeledRangeSlider`
-
-![labeled_range](images/labeled_range.png)
-
-```python
-from qtrangeslider import QLabeledRangeSlider
-```
-
-This has the same API as `QRangeSlider` with the following additional options:
-
-#### `handleLabelPosition`/`setHandleLabelPosition`
-
-Where/whether labels are shown adjacent to slider handles.
-
-**type:** `QLabeledRangeSlider.LabelPosition`
-
-**default:** `LabelPosition.LabelsAbove`
-
-*options:*
-
- `LabelPosition.NoLabel` (no labels shown adjacent to handles)
- `LabelPosition.LabelsAbove`
- `LabelPosition.LabelsBelow`
- `LabelPosition.LabelsRight` (alias for `LabelPosition.LabelsAbove`)
- `LabelPosition.LabelsLeft` (alias for `LabelPosition.LabelsBelow`)
-
-
-#### `edgeLabelMode`/`setEdgeLabelMode`
-
-**type:** `QLabeledRangeSlider.EdgeLabelMode`
-
-**default:** `EdgeLabelMode.LabelsAbove`
-
-*options:*
-
- `EdgeLabelMode.NoLabel`: no labels shown at slider extremes
- `EdgeLabelMode.LabelIsRange`: edge labels shown the min/max values
- `EdgeLabelMode.LabelIsValue`: edge labels shown the slider range
-
-
-#### fine tuning position of labels:
-
-If you find that you need to fine tune the position of the handle labels:
-
- `QLabeledRangeSlider.label_shift_x`: adjust horizontal label position
- `QLabeledRangeSlider.label_shift_y`: adjust vertical label position
-
-### `QLabeledSlider`
-
-
-![labeled_range](images/labeled_qslider.png)
-
-```python
-from qtrangeslider import QLabeledSlider
-```
-
-(no additional options at this point)

+using [Qt Style Sheets](https://doc.qt.io/qt-5/stylesheet-reference.html), then
+`QRangeSlider` will inherit any styles applied to `QSlider` (since it inherits
+from QSlider).  If you'd like to style `QRangeSlider` differently than `QSlider`,
+then you can also target it directly in your style sheet.  The one "special"
+property for QRangeSlider is `qproperty-barColor`, which sets the color of the
+bar between the handles.
+
+> The code for these example widgets is [here](examples/demo_widget.py)

+## Labeled Sliders
+
+This package also includes two "labeled" slider variants. One for `QRangeSlider`, and one for the native `QSlider`:
+
+### `QLabeledRangeSlider`
+
+![labeled_range](images/labeled_range.png)
+
+```python
+from superqt import QLabeledRangeSlider
+```
+
+This has the same API as `QRangeSlider` with the following additional options:
+
+#### `handleLabelPosition`/`setHandleLabelPosition`
+
+Where/whether labels are shown adjacent to slider handles.
+
+**type:** `QLabeledRangeSlider.LabelPosition`
+
+**default:** `LabelPosition.LabelsAbove`
+
+*options:*
+
+- `LabelPosition.NoLabel` (no labels shown adjacent to handles)
+- `LabelPosition.LabelsAbove`
+- `LabelPosition.LabelsBelow`
+- `LabelPosition.LabelsRight` (alias for `LabelPosition.LabelsAbove`)
+- `LabelPosition.LabelsLeft` (alias for `LabelPosition.LabelsBelow`)
+
+#### `edgeLabelMode`/`setEdgeLabelMode`
+
+**type:** `QLabeledRangeSlider.EdgeLabelMode`
+
+**default:** `EdgeLabelMode.LabelIsRange`
+
+*options:*
+
+- `EdgeLabelMode.NoLabel`: no labels shown at slider extremes
+- `EdgeLabelMode.LabelIsRange`: edge labels shown the min/max values
+- `EdgeLabelMode.LabelIsValue`: edge labels shown the slider range
+
+#### fine tuning position of labels:
+
+If you find that you need to fine tune the position of the handle labels:
+
+- `QLabeledRangeSlider.label_shift_x`: adjust horizontal label position
+- `QLabeledRangeSlider.label_shift_y`: adjust vertical label position
+
+### `QLabeledSlider`
+
+![labeled_range](images/labeled_qslider.png)
+
+```python
+from superqt import QLabeledSlider
+```
+
+(no additional options at this point)

+"""Generic Sliders with internal python-based models
+
+This module reimplements most of the logic from qslider.cpp in python:
+https://code.woboq.org/qt5/qtbase/src/widgets/widgets/qslider.cpp.html
+
+This probably looks like tremendous overkill at first (and it may be!),
+since a it's possible to acheive a very reasonable "float slider" by
+scaling input float values to some internal integer range for the QSlider,
+and converting back to float when getting `value()`.  However, one still
+runs into overflow limitations due to the internal integer model.
+
+In order to circumvent them, one needs to reimplement more and more of
+the attributes from QSliderPrivate in order to have the slider behave
+like a native slider (with all of the proper signals and options).
+So that's what `_GenericSlider` is below.
+
+`_GenericRangeSlider` is a variant that expects `value()` and
+`sliderPosition()` to be a sequence of scalars rather than a single
+scalar (with one handle per item), and it forms the basis of
+QRangeSlider.
