Title: [Release][GUI] ImGui-SFML
Post by: Elias Daler on April 12, 2016, 11:49:01 am
Github (https://github.com/EliasD/imgui-sfml)

ImGui is a wonderful library which lets you easily add debug / tools GUI for your game.
A while ago this (http://en.sfml-dev.org/forums/index.php?topic=17185.0) back-end was released and my repository is based on it while improving(?) / changing some stuff.

Here's how I use ImGui in level editor of Re:creation (http://en.sfml-dev.org/forums/index.php?topic=18062.0):

I also use it for my in-game console.

You can find an example code inside of README for repository.
I'm not sure it's 100% complete, so let's discuss it! :)

I love that library.

Aside from the new
ImGui::Image(someTexture);
(which is indeed very convenient), what else is new from the original repo? Also, when I was using the original, I noticed that if you resize the window after creation, the ImGui objects stopped rendering and working properly. Did you experience that too? And if so, is that fixed?

Can't remember all the changes, but not much.
Mostly it's .h/.cpp code separation (using static variables in .h is just asking for trouble!) and also:

* Mouse wheel button support
* Custom TextureId in rendering callback (which makes sf::Texture overload possible)
* Better delta time calculation using sf::Clock::restart (not much of a difference...)
* Some small refactorings which don't change functionality but made code better looking for my coding standards :)

Also, when I was using the original, I noticed that if you resize the window after creation, the ImGui objects stopped rendering and working properly. Did you experience that too? And if so, is that fixed?
This worked fine for me using original repo. :)

About the problem I mentioned, it happens when you use sf::RenderWindow::setFramerateLimit(...). If you don't set a limit it works fine.

Is this or something similar to this available for the SFML.NET Bindings?

I fixed it just now. Can you please check out the latest version to see it it works for you?

Don't think so, though you probably can write some bindings for it yourself (it's just a few calls!)

Another thing: there's now ImGui::ImageButton support which was added by susnux. I've also added alternative cursors support which you can use by calling ImGui::SetMouseCursor. The system cursor in your SFML window gets disabled and ImGui draws it instead if you use non standard cursor.

Good work! I have some suggestions for improvments

* The content of imconfig-SFML.h is not copied in *my* imgui.h but the header of imgui itself.
* the CMAKE step is not very clear. What is IMGUI_ROOT and what value is it set? I just added it my way :-)
* OpenGL is required so CMAKE also needs

find_package(OpenGL REQUIRED)
include_directories(${OPENGL_INCLUDE_DIR})
target_link_libraries(${OPENGL_LIBRARIES})

Edit:
There are two warnings. A trailing newline in imconfig-SFML.h and a unused parameter size in line 211 imgui-SFML.cpp. You want me to create a PR for that?

IMGUI is awesome but I've noticed those warnings too and I don't know how to fix them but apart from that it works great.

Create an issue about that and Stephen Ma (https://twitter.com/tehPHEN) will probably take a look at it (I'm not very good with CMAKE :D)

The warnings should be fixed now. The one with unused variable named 'size' was actually a bug, I need to use it.

I'm using this for something and I'd like to have icons on buttons. Is there a way to do that and still have three shades of button (idle, hovered, being pressed - I want entire sprite to change tint a little like normal buttons do) or not?

Also, is there some more powerful button function that'd let me catch right click or double click separately (I assume double click is possible in my code but I ask about a built in method)? I have a need to do one thing when button is pressed and another when it's double/right clicked.

And I have this code (inside a window begin+end pair of course) and it works only for the first right button, is that something with ids, using same texture, etc? What do I do?

sf::Sprite spr(m_iconstex);
    for(int i = 0; i < 5; ++i)
    {
        spr.setTextureRect(sf::IntRect(0, i * 32, 32, 32));
        if(imgui::ImageButton(spr, 1))
            std::printf("bum right\n");

        imgui::SameLine();
        spr.setTextureRect(sf::IntRect(32, i * 32, 32, 32));
        if(imgui::ImageButton(spr, 1))
            std::printf("bum left\n");
    }

I now changed it to
 sf::Sprite spr(m_iconstex);
    for(int i = 0; i < 5; ++i)
    {
        spr.setTextureRect(sf::IntRect(0, i * 32, 32, 32));
        imgui::PushID(2 * i + 0);
        if(imgui::ImageButton(spr, 1))
            std::printf("bum right\n");

        imgui::PopID();
        imgui::SameLine();
        spr.setTextureRect(sf::IntRect(32, i * 32, 32, 32));
        imgui::PushID(2 * i + 1);
        if(imgui::ImageButton(spr, 1))
            std::printf("bum left\n");

        imgui::PopID();
    }
and it works. I skimmed through the primer on ids in the faq and read your image button source and then image button function that it calls and it uses texture as id so that's why this happened.

The easiest way to do icons I've seen (even Omar recommended this for now) is to embed icons in your font and then use images as symbols. :D
As for other questions - I have no experience with that, sorry. :)
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: FRex on August 24, 2016, 06:03:25 pm
This is really bad, my icons are colorful, and I don't want to fiddle with a font if there is a shortcut to do picture on a button. I'll make them a little transparent and make background part 100% transparent or something but it's still really silly to not have such a feature when there are things like trees, sliders and windows and done so so well.

Oh, that makes situation a bit harder. I suggest you to just check out how ImGui::Button is implemented and try to implement the same stuff yourself by example. I don't think that inserting images and other stuff in regular buttons is supported at the moment.

Post by: Elias Daler on November 02, 2016, 08:27:37 pm
Okay, I've managed to finally remove push/pop/resetGLStates!
This took a lot of time to came up with, but looks like everything works fine! It would be nice to see people confirm this, so please, use the latest version and try it yourself. :)
This give 2-3x rendering speed improvements which is really awesome.

And btw, I want to improve interface a bit, by maing users to pass window/renderTarget into free functions like Update and Render, instead of ImGui-SFML having raw internal pointers to them.
Feel free to comment on this idea here here (https://github.com/eliasdaler/imgui-sfml/issues/12).
But from the responses I have already received, no one is against it, so I'm planning to start working on it soon.
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: Elias Daler on June 02, 2017, 01:09:45 am
One important change happened. Now you should call ImGui::SFML::Render(target), so that resetGLStates is called. It seems like it's necessary, because SFML changed something about the state which breaks stuff in some conditions. Maybe I'll be able to find out what exactly causes that.

(http://i.imgur.com/eXOR860.png)
I've finally found out how load custom fonts. I'll copy info from README:

Default font is loaded if you don't pass false in ImGui::SFML::Init. Call ImGui::SFML::Init(window, false); if you don't want default font to be loaded.

Load your fonts like this:
IO.Fonts->Clear(); // clear fonts if you loaded some before (even if only default one was loaded)
// IO.Fonts->AddFontDefault(); // this will load default font as well
IO.Fonts->AddFontFromFileTTF("font1.ttf", 8.f);
IO.Fonts->AddFontFromFileTTF("font2.ttf", 12.f);

ImGui::SFML::UpdateFontTexture(); // important call: updates font texture
And use them like this:
ImGui::PushFont(ImGui::GetIO().Fonts->Fonts[0]);
ImGui::Button("Look at this pretty button");
ImGui::PopFont();

ImGui::PushFont(ImGui::GetIO().Fonts->Fonts[1]);
ImGui::TextUnformatted("IT WORKS!");
ImGui::PopFont();
The first loaded font is treated as the default one and doesn't need to be pushed with ImGui::PushFont.

Hi,

first thank you for the lib <3

There's just one thing that don't work, when I try to do :
const sf::Texture& tex = TextureManager::getTexture("randomName");
ImGui::Image(tex);

but the compiler tells me :

Quote
'ImGui::Image' : the function doesn't take 1 argument

Can somebody help me please ?

Are you sure you've included ImGui-SFML's header in this file?
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: Hawkrex on October 14, 2017, 01:43:01 pm
I just find out that in the version of imgui-SFML.h I had, there was no include guard. So I added a #pragma once and it works.
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: FRex on November 20, 2017, 05:34:39 am
I've made a script to merge imgui and imgui-sfml into a pair of files, maybe someone will find it useful too. https://gist.github.com/FRex/41b41708daf87d22cf3557766b9dff9b

Is there a way to use imgui & imgui-sfml using git submodules? I encountered a problem related to the custom     imgui config, which needs to be overwritten (as you wrote on your github readme). My workaround is to fork the official imgui, replace the config and use this repo as submodule. But I'm not satisfied by this solution.

Is there a way to determine an external imconfig without replacing the file?

Like
./
    extlibs/
        imgui --> submodule to the offical imgui
        imgui-sfml --> submodule to your imgui-sfml
    include/
        imconfig.h --> my custom imconfig


I want to keep thirdparty libs and my code separate.
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: dabbertorres on January 06, 2018, 11:06:53 pm
I've just added a #include <imgui-sfml/imconfig-SFML.h> to my imconfig.h.

Make the compiler do the copying for me.

For reference, I have a similar project file structure:

./project-root/
    imgui/
    imgui-sfml/
    project/
        imconfig.h
        ...

I didn't get it managed. Can you explain your approach more in detail, please? :)
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: dabbertorres on January 11, 2018, 04:26:32 pm
Sure.

Here's the project layout:
Code: [Select]
./
  imgui/
    imgui.h
    ...
  imgui-sfml/
    imconfig-SFML.h
    imgui-SFML.h
    ...
  project/
    imconfig.h
    main.cpp

project/imconfig.h contains
#include <imgui-sfml/imconfig-SFML.h>

project/main.cpp contains
#include <imgui.h>
#include <imgui-sfml/imgui-SFML.h>

I have the project root directory, project/, and imgui/ folders as include directories, ie: "-I$PROJECT_DIR -I$PROJECT_DIR/project -I$PROJECT_DIR/imgui"
This is needed because imgui.h has #include "imconfig.h", and imgui-SFML.cpp has #include <imgui.h>

You'll also have to make sure you delete, (or rename) imgui/imconfig.h, otherwise you'll run into conflicts at compile time with your project/imconfig.h
Or you could even just use imgui/imconfig.h, and not have a project/imconfig.h

Nope, I'm drawing the image and then I detect a click on it. Then I just do this:
tileIndex = (clickPos - tileImagePos) / tileSize

Context management is now explicit in imgui so your SFML-imgui doesn't work with imgui master head (i.e. it uses the now gone Shutdown()).
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: Elias Daler on February 09, 2018, 08:37:04 am
Yes, an issue was created about that. I plan to create a separate branch to handle both master and latest release of Imgui. :)
Title: Re: [Release][GUI] SFML + ImGui lib
Post by: FRex on February 09, 2018, 11:56:42 am
Great. It's kinda annoying there wasn't a shortcut provided by IMGUI since overloading functions was why it was in C++ in the first place. I'm using commit 07ee5390 from it now but it was surprising it failed to work out of the box on two masters.
Title: Re: [Release][GUI] SFML + ImGui lib

the mouse click when i am inside an imgui window, when i choose some options in my window, some tile will be pasted on the map...

This should just be a simple fix right? I feel like this is an obvious fix.

I'm also getting the same errors whereas it worked for people above us. Strange, isn't it?

Hi, I keep getting these errors, I've done all the recommended solutions but I'm unsure how to proceed.

Hello. Please follow this tutorial: https://eliasdaler.github.io/using-imgui-with-sfml-pt1/

You probably didn't do step 5 in "Setting up"

Worked very hard on this branch of ImGui-SFML recently: https://github.com/eliasdaler/imgui-sfml/tree/develop

Please, check it out! See how easy it is to integrate ImGui-SFML into your CMake-based projects. If it all goes well for everyone, it'll be soon merged into master and ImGui-SFML v.2.0 will be here.

Basically, all you have to do now is this:

find_package(ImGui-SFML REQUIRED)
target_link_libraries(my_target PRIVATE ImGui-SFML::ImGui-SFML)

Post by: Elias Daler on May 10, 2019, 05:57:53 pm
(https://i.imgur.com/vCXP1uu.png)

https://github.com/eliasdaler/imgui-sfml/releases/tag/v2.0

Note the updated usage requirements!

* SFML >= 2.5.0
* ImGui >= 1.68

This release greatly improves CMake and build support:


find_package(ImGui-SFML REQUIRED)
target_link_libraries(my_target PRIVATE ImGui-SFML::ImGui-SFML)


This release doesn't bring new features, but it's the first release which has proper version in CMake + it's just so good, it's a shame not to name it "2.0".

Semantic versioning will be used for future releases.

What IDE/build system are you using? You're not linking to ImGui and ImGui-SFML, which means that you haven't included imgui.cpp, imgui_widgets.cpp and imgui-SFMLcpp to your build
