Support glade

[antoyo]

Idea:

glade_view!("file.glade");

instead of using view! {} when we want to use a UI from a glade file.

Any progress on this? With recent improvements to Glade, it is going to be the go-to solution for designing GTK interfaces.

[antoyo]

Unfortunately, no.
Anyone wants to work on this issue?
@zzeroo Maybe?

With recent improvements to Glade, it is going to be the go-to solution for designing GTK interfaces.

If the experience is anything like on GTK, I doubt it, until proven : ) I've still to find that GUI framework, where XML files for declaring how the UI looks work so well and non-sluggish and are integrated so well, that there is no issue with the types or difficult to figure out stuff, that it makes sense to use such a representation. I will go on hoping for one such framework.

[mikolajpp]

@ZelphirKaltstahl Unless I misunderstood you, the point of glade is not to touch XML. It is a GUI tool. I have checked the latest version, and on the surface it works really well.

Unsure what you mean about types. Glade objects are using standard gobject interfacing.

[antoyo]

There's no point in having this debate here.
Some people like WYSIWYG tools to create GUI and some people don't (I personally don't, but whatever).
Since many people want this feature I'll do it for the version 1.0.
It might take a couple of months to have it, though.

I have written a small macro to reduce boilerplate while loading glade file here: https://github.com/thefzsalam/dvm-ng/blob/master/src/views/macros.rs

[thefzsalam]

I couldn't find a way to initialize non constant variables outside main().
I resorted to defining a method build() which accepts gtk::Builder and calling let my_view = MyView::build(Builder::new_from_str(include_str!("file.glade"))); from main() instead.

any updates so far? This idea looks amazing!

[antoyo]

@MGlolenstine: unfortunately, no.

[antoyo]

I added an example showing how to use Glade with relm. I haven't created the macro to make this automatic yet.

[antoyo]

@MGlolenstine @thefzsalam : How do you expect this to work? Something like this macro?

[blfpd]

Is this issue still a priority for 1.0? Or useful?
Questioning this after reading Chris Davis’ Glade Not Recommended blog post.

[antoyo]

@batisteo Don't worry, relm will always provide the declarative syntax. This issue is just about adding an alternative to write the UI using a graphical tool.
By the way, read the comments in this article: it seems the author went a bit too far ;) .

[blfpd]

I was just afraid that we’re pushing on you a soon-to-be deprecated feature of GTK 4. Seems it’s not really the case indeed.

[pepijndevos]

What does Relm offer when combined with Glade?
Imagine you're working with a designer who doesn't do Rust, would it make sense to have them design in Glade, or it kind of defeats most of the purpose of Relm, and it's better to just have them work in whatever prototyping thing they like and implement it in "pure" Relm?

[antoyo]

@pepijndevos Well, the point of this issue is to gather ideas about how relm could be combined with Glade. I'm still waiting for the other people to provide ideas, especially regarding how events should be handled.

So, I can't really answer your questions. I guess it's up to you.
