One more thing, would Grapefruit work with files created by Glade (UI
builder)?
No, it won’t, I’m afraid. There is, for example, the principal problem that
Glade is GTK+-specific (as far as I know) while Grapefruit shall have a
toolkit-independent library interface.
However, I don’t think it is such a good idea to support traditional GUI
builders. These builders typically let you design a static interface but you
have to code event handlers or similar stuff completely by hand and you have
practically no support for dynamic user interfaces (user interfaces that
change their structure).
On the other hand, Grapefruit uses arrow notation for composing user
interfaces so that the source code already reflects the visual appearence of
the GUI to a certain degree. For example, you just list the widgets of a box
and say what their input and output signals are.
Make sense.
That said, I still think it might be a good idea to use a GUI builder
together with Grapefruit. But such a builder should be specifically
designed for Grapefruit, in my opinion. I already have some rough ideas
in my mind about how such a builder could work. I’d want it to cover
also the communication between the UI components (using signals) and
maybe even dynamic user interfaces. If you are interested in my ideas,
please ask.
That would be a great addition to Grapefruit.
Time for me to read fully about FRP and arrow notation and go from there!
Best wishes,
Wolfgang
