C and GUI

>>58512003
Either make calls to X or use a library.
C users usually use gtk, but if you are willing to use c++, qt is really great.

If you really knew C, you would know that you can use libraries like GTK+ to make GUI for your programs.

>>58512003
You can't because sepples faggots think that you can't do gui without abusing OOP and so they wrote every gui library in sepples.

>>58512003
Qt, gtk, wx, ide shit, cairo, win.form, cocoa, fltk, wayland, x (it'll be shit)

>>58512121
C++ is not that hard to grasp if you have been writing a lot of C.
If you use something like qtdesigner, you can generate the xml for the design, but you can also paint it all in when launching if you want to.
Qtcreator is a good IDE that makes these things easy.

The 1 minute rundown of Qt:
You make a thread for updating the graphical interface.
Fields have callback functions which is called signals and slots.
Signals is a function Qt automatically generate.
You only declare it so the name and the variable type is declared.
The slots is the function that gets called when you emit the signal.
You connect signals to slots either in a wrapper or in the main.

I haven't worked with gtk.

>>58512121

GTK is deprecated by the community and only really used by GNOME and those who are unfortunately stuck with it for legacy reasons.

Qt is the way. Use it as an excuse to learn c++ together with it.

Is there an OS agnostic way to do this, or is that Java's forte?

>>58512412
Well one of Qt's strong points is that, theoretically, the same code can run the three major OS's (not sure about BSD), you just need to compile it on that platform.

>>58512421
Can one use qt creator for a C project?

ttk, iup, libagar, libui

>>58512421

Ok, did not know that. Though it was a pure Linux thing.

Anyway how does it compare to HTML5 for say, app building?

I've been wondering about this, too. I know there are libraries to do this stuff but what exactly are the libraries? Is it just very advanced code in that language or is it something very low level that people set up to be able to use in a higher level language like c or c++?

>>58512480
it's just well thought out code (hopefully, unless the lib sucks) in that language, yes

>>58512490
How does it work though? Would I be able to do these things in c++ without the libraries if I knew it well enough? Are the libraries available pretty much good enough that no one needs to make new ones, essentially?

>>58512436
If you know C you'll be able to work with Qt even if you don't know much about c++ besides a couple functions.
I'm learning C++ on the go as I work in my Qt project.

>>58512475

>>58512436
Qt is C++. Just bite the bullet and go C++, C nowadays is really only used for embedded systems (which wouldn't necessarily use GUIs anyway). If you want to make it hacker-tier, use ncurses.

>>58512505

Dont listen to the QT/C++ shills

>>58512518
Every element of the GUI is an object including the window but I don't know much about OOP myself and I'm able to work with it, just understand that objects have properties (variables) and methods (functions).

You shouldn't have listened to /dpt/.

If you wanted to develop the full stack to make applications that people will actually use, you can't just know C. In today's world, C is only for fast calculation libraries and hardware drivers.

Is ncurses easier to learn?
>C nowadays is really only used for embedded systems (which wouldn't necessarily use GUIs anyway).
Well, there is a lot of C software in the Linux world. Most of the stuff I use is C, not C++.
And I use a lot of GTK software which does get updated on a regular basis.
And if I went C++, I'd probably write C with classes and objects.
>>58512538
What's wrong with QT?
>>58512542
Well, a few years ago I opened a simple C# project without knowing anything about OOP besides the general idea of classes and objects, like, father belongs to the class human, stuff like that... Surprisingly enough, I was able to get the hang of it in half an hour and rewrite the project.

>>58512574
if you're reading through TAOCP or TCPL and you go "oh, i genuinely understand why they made these decisions" and aren't confused, you're about to have made it.

>>58512597

>>58512596
>Well, a few years ago I opened a simple C# project without knowing anything about OOP besides the general idea of classes and objects, like, father belongs to the class human, stuff like that... Surprisingly enough, I was able to get the hang of it in half an hour and rewrite the project.

Putting memes aside, this is because OOP is actually really easy to read and work with when you're using simple polymorphism, encapsulation, and logical hierarchies of concepts. OOP gets the bad rap when people go balls to the wall with DESIGN PATTERNS and they're writing a sub-2000 LoC library or utility.

Also, not sure about your experience, but I find C# to be one of the easiest languages to read, especially when you come back to a project years later or if you're reading something someone else wrote.

>>58512614
everything

>>58512596
>What's wrong with QT?
It's complex and it's sepples. When using Qt's event system, you need to use a special compiler that emits the C++ code implementing your code because that event system is presented as a special extension to C++. Also, Qt programs' appearance and UI behaviour are configured with big XML files. A clusterfuck.

>>58512596
>Is ncurses easier to learn?
Ncurses is difficult, but it's worth it, if only to make your software look like the soundblaster setup screen.

>And if I went C++, I'd probably write C with classes and objects.
Then learn to write C++. Or don't, doesn't matter much.

>>58512636
Type hierarchies are never a good idea, and they always make the program harder to understand.

When there's no type hierarchy, you don't have to manage the type hierarchy.

>>58512136
Your computer time is over.
I want to you turn off your computer and start doing your homework.

>>58512636
I find C# one of the harder languages to read because everyone goes crazy with LINQ. Combine that with the JavaScript-esque overuse of first-class functions, and with proxy classes and whatever, and programs just become a flurry of inappropriately deep-nested confusion.

.NET Core is already a thing for lightweight portable libraries, and people have been using Mono to dev cross-platform for a while now.

I don't understand what you mean by "looks wrong", can you provide any example?
Usually when I can I use GTK applications, I have a nice dark GTK2/3 theme set up and everything looks consistent.
If I really have to use Qt apps I have it set up to use GTK themes by QGtkStyle.
So on my desktop everything uses the same style and looks consistent no matter if it uses GTK or Qt, which means that the only differences are: perfomance and ease of coding.

I'm trying out IUP it has C api, It's mostly written in C and it supports windows too, it uses native widgets so on linux you'll see you application as a GTK 2 or 3 app while on windows will look like any other app.
They have tutorials and good documentation on their webpage.
Also, if you don't want to fix your application over and over again then don't use GTK directly, they change the API so often you'll have to invest a good amount of time porting your application to newer a GTK version. IUP can give you a table API if that's what you're looking for.

Win32 API is written in asm and C. Even if you interface it with C++, you're still using C style code.

>>58512480
>>58512502
It usually depends on OS/platform specific code (either directly drawing image using hardware video modes, or calls to the OS window system API), so the code for say Windows vs Linux is different, but the library provides common functionality on all systems. So for example, your GUI library might have a ShowMessageBox(char *string) function, and it would be implemented differently on Windows vs Linux, but the function interface is the same. Basically similar to how printf() works in C, there's a function signature and behavior required by the C standard, but the actual code to implement it depends on platform-specific hardware interrupts.

>>58513010
>>58513017
The modern fork of Dev-C++ is lighter and simpler, until you're actually developing serious commercial software there's really no need for a fancy bloated IDE.

>>58518037
Most GUI and graphics stuff is a seperate library usually written in assembly (that's the only way to directly interface with the graphics hardware), advantage of C is that it's kind of the standardized language on all platforms, so it's one of the top priority for making libraries compatible with.

>>58518205
In the early days of PC gaming C and asm were the only languages fast enough. Even today, you write C-style C++ if you care about performance, bloated stuff like STL is too slow.

>>58520223
No GUI tool is. Remember, the C standard is aimed at portability, and it doesn't even assume the existence of a keyboard or monitor, or even a file system. You could write a completely conforming ANSI C compiler for a system with punch cards for input, a printer for output, and non-hierarchical storage on magnetic tapes.

there's some relevant cases in which C++ language features outperform C, like when you need to pass first-class functions around. in C++ you can template a function object and get inline performance, in C you're stuck with void pointers and a reference/function call overhead
