### Apply and Update Status with sv_ttk Themes in Tkinter

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Demonstrates how to set, toggle, and update status labels for themes using sv_ttk. It includes examples of creating basic Tkinter widgets, managing theme changes, and handling different theme modes (dark/light).

```python
import tkinter
from tkinter import ttk
import sv_ttk

# Assume root, status_label, info_label, sv_ttk are defined and imported
# For demonstration purposes, let's define them here:
root = tkinter.Tk()
root.title("Sun Valley Theme Demo")
root.geometry("400x400")

status_label = ttk.Label(root, text="", font=("Helvetica", 12))
status_label.pack(pady=10)

info_label = ttk.Label(root, text="", font=("Helvetica", 10))
info_label.pack(pady=5)

def update_status():
    current_theme = sv_ttk.get_theme()
    status_label.config(text=f"Current theme: {current_theme.upper()}")

    if current_theme == "dark":
        info_text = "Dark mode active - using darker color scheme"
        root.configure(bg="#1c1c1c")
    elif current_theme == "light":
        info_text = "Light mode active - using lighter color scheme"
        root.configure(bg="#fafafa")
    else:
        info_text = f"Non-Sun Valley theme: {current_theme}"

    info_label.config(text=info_text)

def toggle_with_feedback():
    sv_ttk.toggle_theme()
    update_status()

btn_frame = ttk.Frame(root, padding=20)
btn_frame.pack()

tkinter.Button(btn_frame, text="Set Dark", command=lambda: [sv_ttk.use_dark_theme(), update_status()]).grid(row=0, column=0, padx=5, pady=5)
tkinter.Button(btn_frame, text="Set Light", command=lambda: [sv_ttk.use_light_theme(), update_status()]).grid(row=0, column=1, padx=5, pady=5)
tkinter.Button(btn_frame, text="Toggle", command=toggle_with_feedback).grid(row=0, column=2, padx=5, pady=5)

notebook = ttk.Notebook(root)
notebook.pack(pady=20, padx=20, fill="both", expand=True)

tab1 = ttk.Frame(notebook)
notebook.add(tab1, text="Tab 1")
tkinter.Label(tab1, text="Content in Tab 1").pack(pady=20)
tkinter.Scale(tab1, from_=0, to=100, orient="horizontal", length=200).pack(pady=10)

tab2 = ttk.Frame(notebook)
notebook.add(tab2, text="Tab 2")
tkinter.Label(tab2, text="Content in Tab 2").pack(pady=20)
tkinter.Spinbox(tab2, from_=0, to=100, width=15).pack(pady=10)

# Initialize with dark theme
sv_ttk.use_dark_theme()
update_status()

root.mainloop()

```

### Set Dark or Light Theme with sv_ttk

Source: https://github.com/rdbende/sun-valley-ttk-theme/wiki/Usage-with-Python

Demonstrates how to set either a dark or light Sun Valley theme for a Tkinter application. It requires importing tkinter, ttk, and sv_ttk, then calling either `use_dark_theme()` or `use_light_theme()` before starting the main loop.

```python
import tkinter
from tkinter import ttk

import sv_ttk

root = tkinter.Tk()

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

sv_ttk.use_dark_theme()
sv_ttk.use_light_theme()

root.mainloop()
```

--------------------------------

### Apply Sun Valley Theme with set_theme() in Python

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Applies the Sun Valley theme to a Tkinter application in either 'dark' or 'light' mode. This function is the primary method for theme management. It requires Tkinter and sv_ttk to be installed. The input is a case-insensitive string specifying the theme mode.

```python
import tkinter
from tkinter import ttk
import sv_ttk

# Create main window
root = tkinter.Tk()
root.title("Sun Valley Theme Demo")
root.geometry("400x300")

# Create some widgets to demonstrate the theme
label = ttk.Label(root, text="Welcome to Sun Valley Theme")
label.pack(pady=10)

entry = ttk.Entry(root, width=30)
entry.pack(pady=5)
entry.insert(0, "Type something here...")

button = ttk.Button(root, text="Click Me!")
button.pack(pady=5)

checkbox = ttk.Checkbutton(root, text="Enable notifications")
checkbox.pack(pady=5)

# Apply dark theme
sv_ttk.set_theme("dark")

root.mainloop()
```

--------------------------------

### Integrate sv_ttk with System Theme Detection using darkdetect

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Demonstrates how to automatically apply system theme preferences (light or dark) to Tkinter applications using `sv_ttk` and the `darkdetect` package. It includes fallback mechanisms and UI updates based on detected themes.

```python
import tkinter
from tkinter import ttk
import sv_ttk

try:
    import darkdetect
    system_theme = darkdetect.theme()  # Returns "Dark" or "Light"
except ImportError:
    system_theme = "Light"
    print("darkdetect not installed, defaulting to light theme")

root = tkinter.Tk()
root.title("System Theme Detection")
root.geometry("450x300")

tkinter.Label(root, text=f"System Theme: {system_theme}", font=("Helvetica", 14)).pack(pady=20)

listbox_frame = ttk.Frame(root)
listbox_frame.pack(pady=10, padx=20, fill="both", expand=True)

scrollbar = ttk.Scrollbar(listbox_frame)
scrollbar.pack(side="right", fill="y")

listbox = tkinter.Listbox(listbox_frame, yscrollcommand=scrollbar.set, height=8)
for i in range(20):
    listbox.insert(tkinter.END, f"Item {i+1}")
listbox.pack(side="left", fill="both", expand=True)
scrollbar.config(command=listbox.yview)

def apply_system_theme():
    try:
        import darkdetect
        detected = darkdetect.theme().lower()
        sv_ttk.set_theme(detected)
        tkinter.Label(root, text=f"Applied: {detected}").pack()
    except ImportError:
        tkinter.Label(root, text="darkdetect not available").pack()

tkinter.Button(root, text="Apply System Theme", command=apply_system_theme).pack(pady=10)

sv_ttk.set_theme(system_theme.lower())

root.mainloop()

```

--------------------------------

### Manage sv_ttk Themes with Explicit Tkinter Root Windows

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Shows how to apply sv_ttk themes to specific Tkinter root windows, which is crucial for multi-window applications or when avoiding Tkinter's default root. It demonstrates theme setting and retrieval for explicit root instances.

```python
import tkinter
from tkinter import ttk
import sv_ttk

tkinter.NoDefaultRoot()

root = tkinter.Tk()
root.title("Explicit Root Demo")
root.geometry("400x300")

tkinter.Label(root, text="Main Window").pack(pady=10)
tkinter.Button(root, text="Button in Main Window").pack(pady=5)

sv_ttk.set_theme("dark", root=root)

second_window = tkinter.Toplevel(root)
second_window.title("Second Window")
second_window.geometry("300x200")

tkinter.Label(second_window, text="Second Window").pack(pady=10)

def show_theme():
    theme = sv_ttk.get_theme(root=root)
    tkinter.Label(second_window, text=f"Current theme: {theme}").pack()

tkinter.Button(second_window, text="Check Theme", command=show_theme).pack(pady=5)

tkinter.Button(second_window, text="Toggle Theme",
           command=lambda: sv_ttk.toggle_theme(root=root)).pack(pady=5)

root.mainloop()

```

--------------------------------

### Convenience Functions for Dark/Light Theme in Python

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Provides direct functions `use_dark_theme()` and `use_light_theme()` for applying specific Sun Valley theme variants. These are convenient wrappers around `set_theme()` for cleaner code. They require Tkinter and sv_ttk. No specific input is needed as they call `set_theme()` with predefined arguments.

```python
import tkinter
from tkinter import ttk
import sv_ttk

root = tkinter.Tk()
root.geometry("500x400")

# Create a frame with multiple widgets
frame = ttk.Frame(root, padding=20)
frame.pack(fill="both", expand=True)

ttk.Label(frame, text="Theme Selector Demo").pack(pady=10)

# Create radio buttons
theme_var = tkinter.StringVar(value="light")

ttk.Radiobutton(frame, text="Option 1", variable=theme_var, value="opt1").pack(pady=5)
ttk.Radiobutton(frame, text="Option 2", variable=theme_var, value="opt2").pack(pady=5)

# Create buttons to switch themes
btn_frame = ttk.Frame(frame)
btn_frame.pack(pady=20)

ttk.Button(btn_frame, text="Use Dark Theme", command=sv_ttk.use_dark_theme).pack(side="left", padx=5)
ttk.Button(btn_frame, text="Use Light Theme", command=sv_ttk.use_light_theme).pack(side="left", padx=5)

# Create a progress bar
progress = ttk.Progressbar(frame, length=300, mode="determinate", value=60)
progress.pack(pady=10)

# Start with light theme
sv_ttk.use_light_theme()

root.mainloop()
```

--------------------------------

### Handle Invalid Themes with Python Tkinter and sv_ttk

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

This Python code snippet demonstrates how to use the `sv_ttk.set_theme()` function and gracefully handle `RuntimeError` exceptions that occur when invalid theme names are provided. It includes buttons to test both valid ('dark', 'light') and invalid theme inputs to illustrate the error handling mechanism. The code requires the `sv_ttk` and `tkinter` libraries.

```python
import tkinter
from tkinter import ttk
import sv_ttk

root = tkinter.Tk()
root.title("Theme Error Handling")
root.geometry("400x250")

result_label = ttk.Label(root, text="", font=("Helvetica", 10))
result_label.pack(pady=20)

def try_set_theme(theme_name):
    try:
        sv_ttk.set_theme(theme_name)
        result_label.config(text=f"✓ Successfully set theme to: {theme_name}")
    except RuntimeError as e:
        result_label.config(text=f"✗ Error: {str(e)}")
    except Exception as e:
        result_label.config(text=f"✗ Unexpected error: {str(e)}")

frame = ttk.Frame(root, padding=10)
frame.pack()

ttk.Button(frame, text='Try "dark"',
           command=lambda: try_set_theme("dark")).grid(row=0, column=0, padx=5, pady=5)	tk.Button(frame, text='Try "light"',
           command=lambda: try_set_theme("light")).grid(row=0, column=1, padx=5, pady=5)

ttk.Button(frame, text='Try "DARK" (caps)',
           command=lambda: try_set_theme("DARK")).grid(row=1, column=0, padx=5, pady=5)	tk.Button(frame, text='Try "blue"',
           command=lambda: try_set_theme("blue")).grid(row=1, column=1, padx=5, pady=5)

ttk.Label(root, text="Note: Theme names are case-insensitive\nValid values: 'dark' or 'light'",
          font=("Helvetica", 9)).pack(pady=10)

sv_ttk.use_light_theme() 

root.mainloop()
```

### Query Current Theme with get_theme() in Python

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Returns the name of the currently active theme as a string. For Sun Valley themes, it returns 'dark' or 'light'. For other themes, it returns their respective names. This function is useful for implementing conditional logic based on the active theme. It requires Tkinter and sv_ttk.

```python
import tkinter
from tkinter import ttk
import sv_ttk

root = tkinter.Tk()
root.title("Theme Query Demo")
root.geometry("500x400")

# The actual implementation for get_theme() would typically involve calling it
# and potentially displaying the result or using it in conditional logic.
# Example:
# current_theme = sv_ttk.get_theme()
# print(f"Current theme is: {current_theme}")

# Placeholder for demonstration purposes:
label = ttk.Label(root, text=f"Current theme: {sv_ttk.get_theme()}")
label.pack(pady=20)

# Example of using it to conditionally change something (not fully implemented here)
# if sv_ttk.get_theme() == "dark":
#     # do something for dark theme
# else:
#     # do something for light theme

# Ensure a theme is set to demonstrate get_theme()
sv_ttk.set_theme("light")

root.mainloop()
```

--------------------------------

### Query Current Theme with sv_ttk

Source: https://github.com/rdbende/sun-valley-ttk-theme/wiki/Usage-with-Python

Demonstrates how to retrieve the currently active Sun Valley theme using the `get_theme` method. It returns 'dark' or 'light' if a Sun Valley theme is active, otherwise it returns the name of the non-Sun Valley theme. This is useful for conditional theming logic.

```python
import tkinter
from tkinter import ttk

import sv_ttk

root = tkinter.Tk()

def toggle_theme():
    if sv_ttk.get_theme() == "dark":
        print("Setting theme to light")
        sv_ttk.use_light_theme()
    elif sv_ttk.get_theme() == "light":
        print("Setting theme to dark")
        sv_ttk.use_dark_theme()
    else:
        print("Not Sun Valley theme")

button = ttk.Button(root, text="Toggle theme", command=toggle_theme)
button.pack()

root.mainloop()
```

--------------------------------

### Set Specific Theme (Dark/Light) with sv_ttk

Source: https://github.com/rdbende/sun-valley-ttk-theme/wiki/Usage-with-Python

Shows how to set a specific Sun Valley theme ('dark' or 'light') using the `set_theme` function. This function accepts only 'dark' or 'light' as arguments and will raise an error for any other input. It requires standard Tkinter and sv_ttk imports.

```python
import tkinter
from tkinter import ttk

import sv_ttk

root = tkinter.Tk()

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

sv_ttk.set_theme("dark")

root.mainloop()
```

--------------------------------

### Toggle Theme with sv_ttk

Source: https://github.com/rdbende/sun-valley-ttk-theme/wiki/Usage-with-Python

Illustrates how to toggle between dark and light Sun Valley themes using the `toggle_theme` function. If the application is not currently using a Sun Valley theme, it defaults to the light theme. This involves binding the function to a widget's command.

```python
import tkinter
from tkinter import ttk

import sv_ttk

root = tkinter.Tk()

button = ttk.Button(root, text="Toggle theme", command=sv_ttk.toggle_theme)
button.pack()

root.mainloop()
```

--------------------------------

### Apply Sun Valley theme to Tkinter app

Source: https://github.com/rdbende/sun-valley-ttk-theme/blob/main/README.md

Applies the Sun Valley ttk theme to a Tkinter application. Requires importing tkinter, ttk, and sv_ttk. Sets the theme to 'dark' or 'light'. Outputs a visually themed Tkinter window.

```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()
```

--------------------------------

### Toggle Sun Valley Theme with toggle_theme() in Python

Source: https://context7.com/rdbende/sun-valley-ttk-theme/llms.txt

Dynamically switches between dark and light Sun Valley themes. If the current theme is not a Sun Valley theme, it defaults to light mode. This function is ideal for implementing theme toggle buttons in Tkinter applications. It requires Tkinter and sv_ttk.

```python
import tkinter
from tkinter import ttk
import sv_ttk

root = tkinter.Tk()
root.title("Theme Toggle Demo")
root.geometry("450x350")

# Create main container
container = ttk.Frame(root, padding=15)
container.pack(fill="both", expand=True)

# Header
header = ttk.Label(container, text="Theme Toggle Application", font=("Helvetica", 16, "bold"))
header.pack(pady=10)

# Text widget (not themable but benefits from colorscheme)
text_widget = tkinter.Text(container, height=8, width=40)
text_widget.pack(pady=10)
text_widget.insert("1.0", "This is a text widget.\nClick the toggle button to switch themes.\n\nThe Sun Valley theme transforms your ttk widgets instantly!")

# Combobox
combo = ttk.Combobox(container, values=["Option A", "Option B", "Option C"], state="readonly")
combo.set("Option A")
combo.pack(pady=10)

# Toggle button
toggle_btn = ttk.Button(container, text="Toggle Theme 🌓", command=sv_ttk.toggle_theme)
toggle_btn.pack(pady=10)

# Set initial theme
sv_ttk.set_theme("dark")

root.mainloop()
```

--------------------------------

### Set theme based on system dark mode

Source: https://github.com/rdbende/sun-valley-ttk-theme/blob/main/README.md

Sets the Sun Valley ttk theme to match the system's dark mode preference. It utilizes the 'darkdetect' library to determine the current system theme ('dark' or 'light') and applies it accordingly. Requires importing 'darkdetect' and 'sv_ttk'.

```python
import darkdetect

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

--------------------------------

### Apply dark mode title bar on Windows

Source: https://github.com/rdbende/sun-valley-ttk-theme/blob/main/README.md

Customizes the Tkinter window title bar to match the dark mode theme on Windows. This function adapts to Windows 10 and Windows 11, using 'pywinstyles' for styling. It checks the OS version and applies appropriate window attributes. Requires 'pywinstyles', 'sys', and 'sv_ttk'. Note: Windows 10 has limitations on title bar customization.

```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)
```
