pyqt6-icon-theme 0.1.1

Dynamic SVG icon theming tool for PyQt6

pyqt6-icon-theme

English | 繁體中文

PyQt6 Dynamic Icon Theme Toolkit — Supports automatic light/dark theme switching, hover color effects, and PNG/JPG original color rendering.

Demo

Features

• SVG Dynamic Recoloring — Automatically strips original fill/stroke and applies any custom color
• Theme Awareness — Automatically switches between black (light theme) and white (dark theme) when no custom color is set
• Hover Effect — Switches icon color on mouse enter/leave
• PNG / JPG Support — Renders raster images at any size while preserving original colors
• Caching — Icons are cached by (name, color, size, keep_original) to avoid redundant rendering

Installation

pip install pyqt6-icon-theme

Usage

Import the library:

from pyqt6_icon_theme import IconManager, IconButton

Set the icon directory (supports .svg, .png, .jpg, .jpeg); the path name is customizable:

IconManager.set_icon_dir("icons")

IconButton

• 1st parameter: icon file name — extension is optional
• 2nd parameter: icon size in pixels
• 3rd parameter: icon color in normal state — if None, the color is automatically detected from the window background (black on light, white on dark)
• 4th parameter: icon color on hover — if None, no color change on hover
• 5th parameter: preserve the SVG's original colors — if True, normal_color and hover_color are ignored; defaults to False

IconButton(name, size=16, normal_color=None, hover_color=None, keep_original=False)

Examples

# Auto color based on theme (light = black, dark = white)
btn = IconButton("user.svg", size=30)

# Custom color + hover effect
btn = IconButton("add.svg", size=36,
                 normal_color="#49ADF0",
                 hover_color="#F08884")

# Preserve SVG original colors (unaffected by theme)
btn = IconButton("edit.svg", size=40, keep_original=True)

# PNG/JPG — always displays original colors
btn = IconButton("delete.png", size=40)
