I am trying to paint controls, so I need to eventually Canvas.Draw() to
get a graphic onto a control. I've been working on creating a fully
featured web browser for Lazarus and have been looking at the underlying
widgetset interface code.
Gtk3, which my project currently works great on, uses the now required
Cairo system for painting Gtk widgets. I've already had to patch the
Gtk3 LCL interface section quite a bit to fix errors and I'll submit
those changes when I publish my project.
That would be nice.
However, the LCL Gtk2 widgetset is stuck using the Gdk system for
drawing, even though that was deprecated early on in the Gtk2 lifetime
and Cairo has been recommend for a decade or more. I would like to
submit a patch for Gtk2 replacing Gdk with Cairo, but using a swtich
setting that could be changed at runtime.
+1, maybe add Gtk2UseCairo as default.
.... paths are also welcome, afair win32,qt and gtk2/3 supports paths
and it can be implemented inside widgetsets.
