[Release][GUI] ImGui-SFML

[Elias Daler]

ImGui-SFML got Android port by Peter Repukat! Get it in the latest version.

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 :

'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?

[Hawkrex]

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.

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.

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?

[dabbertorres]

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

Just integrated it to my project... works great !

I want to do a tilemap like your example and i'm wondering how you did it ? Did you use a imagebutton for each tile ? Selectable something ?

Glad it works well for you!

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()).

[Elias Daler]

Yes, an issue was created about that. I plan to create a separate branch to handle both master and latest release of Imgui.

[FRex]

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.

[Elias Daler]

Yeah, it was pretty weird to just merge it into master without time to react to that, heh. :/
