digitalmars.D.learn - Getting Qte5 to work

reply Josh Dredge <josh.dredge outlook.com> writes:
Hi all, I'm completely new to D and while I'm not new to 
programming in general, I mostly do web development, and what 
desktop development I've done has all been with easy 

doesn't date me). I'm trying to experiment in new languages, but 
it's shocking to me how few just don't have GUI builders.

I'm looking at learning D, but would like to stick with what I 
know on desktop in terms of event-driven GUI based applications.

I have Visual D installed, as well as QtCreator and was hoping to 
be able to use Qt with D. I'm happy without any GUI builder for 
now, but still need a working GUI library! Qte5 looks fine but 
need to figure out how to implement it.

I've installed D in "C:\D" (Windows 10 x64).
I've installed Qte5 in "C:\D\Qte5".

Quite simply typing "import Qte5;" into the code doesn't work 
(module not found), and I'm not sure how to make sure the library 
is correctly installed and reference. Is there a setup guide? I 
found one on Youtube but it didn't really explain anything. 
What's the way to do it?

Or any other GUI libraries with examples and set up guides?

Thanks!

Welcome! If by web development you also have back-end programming 
then you should be like 50% know how desktop programming works.

Just an advice, Qte5 isn't well maintained, the other 
alternatives such as 'dlangui' also seems abandoned, so basically 
the only maintained UI library here is gtk-d, but there was 
recently a nice tutorial series written about it.

Though I admit I've kind of dropped from the D for the 6 months.

First, since you are already trying to work with C++ (Qt is a C++ 
framework after all) under the hood you will likely need to 
install MS build tools and Windows SDK, this will get you missing 
libraries and first-class support for building native binaries.

Now to the point - 'module not found' is a compiler message that 
tells you 'there were no such module in module search paths', 
with dmd you can point compiler to look for qte5 dir with -I flag 
(or recently -i to also build these), then you also need to pass 
built .lib OR .obj files for Qte5 that contains compiled code 
otherwise you'll see link errors.

So for building your code it is better (for now) to use 
'dub'(official build system & package manager, usually ships with 
compilers)


Let's just make a new dub project and add qte as dependency 
(since it's already on dub registry)

   - Let's create a new project in current working directory named 
MyAwesomeProject, just hit enter for all questions
     $> dub init MyAwesomeProject

   - Now go to this folder
     $> cd MyAwesomeProject

   - Clone qte5 repo to your project (or download and unzip)
     $> git clone https://github.com/MGWL/QtE5

   - And let's add Qte5 dependency(btw you can see it here 
https://code.dlang.org/packages/qte5), note that it is completely 
unrelated with our cloned repo
     $> dub add qte5

   - Now open your dub.json in your project and replace dependency 
path (we do this because it is semi-abandoned, and last published 
version was 4 years ago, even though there was some recent 
activity on master branch) so your dependency section should like 
this
     "dependencies": {
         "qte5": { "path" : "./QtE5" },
     },

   - If you try to build it right now it will error, so we have to 
"fix" it, so go to QtE5 folder, open dub.json and remove 
'sourceFiles' section, it should build just fine without it.

   - Copy example code from QtE5/example/example.d and replace 
your source/app.d with it

   - Build using dub
     $> dub build

   - Done! Now if you have Qt5 installed and present in you system 
%PATH% environment variable (or copied DLL's next to executable) 
I assume it should work. (since I don't have I can't test if it 
actually works)

   - (Optional) It is possible to (re)generate VisualD project 
after you modify your dub project configuration, (additionally it 
can take any other build options such as --arch or --config, but 
ultimately it generates exactly one variant of all possible 
arch/config flavors)
     $> dub generate visuald

Where to get packages?
D packages and dub (note though that not everyone publish it 
here, some people have extra fancy stuff on their github/gitlab)

Fantastic, thank you! This was super informative and from what I 
can tell seems to be working fine.

Unfortunate that there's not many active GUI projects for D as, 
from what I can tell, it is an excellent language that developers 
would love to be working with! I will give Gtk a go too - I've 
never programmed with it, but I used Ubuntu alot back in the day 
and never really liked applications that used it, but maybe its 
more responsive on Windows or time has fixed the issues!

THanks again, and for the kind welcome!

Fantastic resource, thank you very much. Have that working too! 
And Glade looks like a great interface builder so is likely what 
I’ll be using.

DWT is also still active. The looks are a little outdated as it 
is swt-3 based but works just fine.
