I develop on Ubuntu 18 and when testing my application on Windows and macOS I noticed some icons were shown as broken images. The ones failing are
Gtk.STOCK_FIND. Created as following:
I used these because the code was ported from GTK2 where
new_from_stock was used and the names sound like they come with GTK.
The difference is both Windows and macOS use Adwaita, while I have another icon theme on Ubuntu. Using the inspector and setting Adwaita on the Ubuntu machine shows the icons without problems.
Is there a list of icons available on all platforms for example?
