# PyQt Color Picker

Simple Color Picker Widget created with PyQt to easily get color input from the user.

## Usage

1. To use the Color Picker Widget in a PyQt project make sure you have the `PyQt5` or `PyQt6` library:

```
   pip install PyQt5
   ```
   ```
   pip install PyQt6
   ```

then add the `colorpicker` folder of your PyQt version into your project folder and import `ColorPicker`

```python
   from colorpicker import ColorPicker
   ```

2. To add the widget to your app, create a `360x200` placeholder widget in your ui and add the colorpicker to it.
   When initializing the Color Picker you have the option to pass an initial color to it.

```python
   colorpicker = ColorPicker(my_placeholder) # initial color is black

colorpicker = ColorPicker(my_placeholder, rgb=(255,127,0))     # Use RGB
   colorpicker = ColorPicker(my_placeholder, hsv=(90,80,20))      # Use HSV
   colorpicker = ColorPicker(my_placeholder, hex="33ff88")        # Use Hex
   ```

You can then run `getRGB`/`getHSV`/`getHex` method to get the currently selected color:

```python
   current_color = colorpicker.getRGB()
   ```

* `getRGB` returns a rgb tuple with values from 0-255,
* `getHSV` returns a hsv tuple with values from 0-100,
* `getHex` returns a string without hashtag.

* You can customize the ranges easily:

```python
   hsv = colorpicker.getHSV(360,1)  # hue in degrees, saturation & value from 0 to 1
   rgb = colorpicker.getRGB(100)    # rgb in percent
   hex = colorpicker.getHex(True)   # use hashtag in string
   ```

* You can also set the current color:

```python
    colorpicker.setHSV((50,20,80))      # 0-100
    colorpicker.setRGB((221,34,21))     # 0-255
    colorpicker.setHex("dd3322")        # no hashtag
    ```

* Use ColorPicker's `colorChanged` signal to update directly when the user changes the color:

```python
  colorpicker.colorChanged.connect(my_function)

def my_function():
    print(colorpicker.getColor())
  ```

* For an example with a bigger application based on a main class, look at the `example.py` file.
