QtICO

This package provides tools to manage PyQt icon themes.

The QIcon.fromTheme_ API works with icon themes following the freedesktop icon theme spec, which is great for Linux systems with installed and enabled themes, but not for Windows or OS X, which lack them.

To benefit, you just have to create a theme directory with the right structure and use this package’s functions:

icons (The default directory name)
├hicolor
│├16x16/apps/myapp.png
│├32x32/apps/myapp.png
│┆
│└scalable/apps/myapp.svg
└mypackage-builtin
 ├16x16
 │├actions
 ││├document-open.png
 ││┆
 │├mimetypes
 ││├application-x-mymime.png
 ┆┆┆

This package provides the following functions to ease bundling an in-memory icon theme for those systems:

write_theme_indices

Creates .index.theme files from the .png and .svg files.

write_resources

Create a .qrc and _rc.py file to import the icon data from. (Needs the .index.theme files)

write_iconset

Creates a iconset folder for OSX apps, e.g. via py2app, using the hicolor/<s>x<s>/apps/myapp.png files.

install_icon_theme

To be used in a running application to make the builtin icons available.

The hicolor/<s>x<s>/apps/myapp.png files can be

1. installed to the system by packagers (/usr/share/icons/hicolor/…)
2. subsequently used in a .desktop file (Icon=myapp)
3. used as window icon (self.setWindowIcon(QIcon.fromTheme('myapp')))
