## Installation [![PyPi downloads](https://static.pepy.tech/badge/sv-ttk)](https://pypi.org/project/sv-ttk)
The theme is easily installable as a Python package

```
pip install sv-ttk
```


## Usage [![Documentation](https://img.shields.io/badge/-documentation-%23c368c4)](https://github.com/rdbende/Sun-Valley-ttk-theme/wiki/Usage-with-Python)
> [!NOTE]
> The theme will only be applied to themable (`tkinter.ttk`) widgets, and not with the regular Tkinter widgets, they only benefit from the colorscheme.

For detailed documentation, visit the [wiki page](https://github.com/rdbende/Sun-Valley-ttk-theme/wiki/Usage-with-Python).

```python
import tkinter
from tkinter import ttk

import sv_ttk

root = tkinter.Tk()

button = ttk.Button(root, text="Click me!")
button.pack()

# This is where the magic happens
sv_ttk.set_theme("dark")

root.mainloop()
```


## Tips and tricks
Our intention is to keep the `sv-ttk` package as simple as possible, while making it easy to integrate with other libraries.

### Set the theme to the system theme
You can use the [darkdetect](https://github.com/albertosottile/darkdetect) package to detect the system color scheme. Here's an example:

```python
import darkdetect

sv_ttk.set_theme(darkdetect.theme())
```

It's only a matter of an extra import and passing the result of `darkdetect.theme()` to `sv_ttk.set_theme()`. It's that easy!


### Dark mode title bar on Windows
The Sun Valley theme doesn't change the title bar color on Windows when the theme is set to dark. You can use [pywinstyles](https://github.com/Akascape/py-window-styles) to achieve this. Here's an example:
  
```python
import pywinstyles, sys

def apply_theme_to_titlebar(root):
    version = sys.getwindowsversion()

    if version.major == 10 and version.build >= 22000:
        # Set the title bar color to the background color on Windows 11 for better appearance
        pywinstyles.change_header_color(root, "#1c1c1c" if sv_ttk.get_theme() == "dark" else "#fafafa")
    elif version.major == 10:
        pywinstyles.apply_style(root, "dark" if sv_ttk.get_theme() == "dark" else "normal")

        # A hacky way to update the title bar's color on Windows 10 (it doesn't update instantly like on Windows 11)
        root.wm_attributes("-alpha", 0.99)
        root.wm_attributes("-alpha", 1)

# Example usage (replace `root` with the reference to your main/Toplevel window)
apply_theme_to_titlebar(root)
```

Note that on Windows 10, due to its limitations, you can only set the title bar's color to black for dark mode and white for light mode. On Windows 11 the title bar can be set to any color.


> [!WARNING]
> The `apply_theme_to_titlebar` works on Windows only, so you should check whether the platform is Windows before calling this function.


Here's how the windows look after calling `set_title_bar_color()`:
