QSvgStyle distribution

QSvgStyle is a themeable SVG style for Qt 6 desktop applications (C) Said LANKRI, under the GNU GPL License version 2+

It comes with the style engine (QSvgStyle), a theme builder (QSvgThemeBuilder), a theme manager (QSvgThemeManager) and a built-in svg cleaner courtesy of SVGCleaner team.

QSvgStyle

• Themeable Qt5 style engine using standard SVG documents as themes
• Fast rendering. QSvgStyle renders at the speed of a raster engine, which is at least twice faster than the Qt SVG renderer
• Support for color schemes. The theme can be configured to apply the current color scheme on top of the rendered theme
• Support for Widget palettes. QSvgStyle will honour any QPalette set on a widget
• Complete support for Right-to-Left layouts
• Support for capsule grouping in buttons
• Support for variants for some widgets
• Built-in default theme
• Cleanest QStyle engine code with regular code patterns

QSvgThemeBuilder

• Easy to use GUI tool to build configuration files for themes, with support for multiple preview variants, RTL layouts, enabled/disabled states and others
• Live configuration previews. Any changes made to the settings are immediately effective in the preview area
• Live SVG previews. Any changes externally made to the SVG theme are immediately effective in the preview area
• Inheritance system. A widget can inherit the settings of another one, as such settings are limited to the differences and configuration files are kept to minimal size
• Display of effective values. When a setting is inherited, the effective value is computed and shown in the GUI
• Unique debugging tool to see the Qt rendering internals and detect missing SVG elements in the theme
• Basic SVG generator. Use the built-in SVG generator to generate accurate frames, interiors and shadows to be exported to your favorite SVG editing tool for a faster theme making workflow
• Built-in SVG cleaner. Use the cleaner to reduce the size of your SVG file by a half or more

QSvgThemeManager

• Select the active QSvgStyle theme to apply
• Download online themes
• Live preview of themes

Build the source

Compile

You need the Qt6 development files of the following modules to compile QSvgStyle:

• Qt Base
• Qt SVG
• Qt5 Compatibility module

For debian based systems:

sudo apt install qt6-base-dev qt6-svg-dev qt6-5compat-dev

Then you build it:

$ qmake6
$ make -j

Install

$ sudo make install

Use

You can launch any Qt6 application with QSvgStyle styling by adding a -style option:

$ dolphin -style qsvgstyle

To globally set QSvgStyle as your default style engine, use your favorite desktop's configuration tool. For example, use the System Settings in KDE.

QSvgThemeManager: chose theme and tweak the engine

QSvgStyle will use its built-in theme when no particular theme has been chosen. To choose a theme, use the QSvgThemeManager application.

$ qsvgthememanager

• Choose the active theme and tweak the engine

QSvgThemeBuilder: build theme configuration

QSvgStyle comes with a nice GUI that helps building themes. It can generate both an initial SVG file based on the default theme and its companion config file.

$ qsvgthemebuilder

• QSvgThemeBuilder at startup

• Editing configuration for a flat theme

• Showing effective values of inherited settings

• Quick SVG generator to generate SVG items with frames, interiors and shadows with many generation options

• Export to SVG editing application of accurate, clean and minimal SVG data with given SVG ids
