Bug 157794 – [GTK] Clean up CursorGtk.cpp

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Michael Catanzaro]

We use GdkCursorType extensively in CursorGtk.cpp, but GTK+ does not support this anymore and they're only sure to work under X11. Instead, use supported CSS cursor names.

Also, we have a bunch of custom cursors copied from Firefox. Each of these cursors is nowadays guaranteed to be provided by GTK+, so we don't need any of these anymore.

Maybe we can leave the createNamedCursor helper, but receiving a const char* instead and simply calling gdk_cursor_new_from_name for the default display.

Hm, forgot about this. It should hopefully fix a strange bug we have where our mouse cursor sometimes turns into a crap X11 fallback cursor when hovering over links in Wayland. It's because we set the cursor to GDK_HAND2, which is not supported anymore.

I'll delete it, good catch.
