ImGui LÖVE module

Nice thanks.

I've written a file picker dialog using lfs and imgui. This was my first attempt at using imgui. The lack of documentation made it more difficult than it needed to be starting out, but once I got the hang of relating the C++ documentation to the Lua bindings, it went quite smoothly. I'm really happy with this module, thank you for taking the time to write it.



It's up on Gitlab if anyone wants to use it. I will continue to work on it, as I'm using it in an animation editor I'm writing. Right now it only has an open dialog. The two major features I have planned are a save dialog, and thumbnail previews for images.

Are there any build instructions?

I did the cmake thing but can't see what file to use

Code: Select all

kbmonkey@multivac:love-imgui-0.8$ cmake .
-- The C compiler identification is GNU 4.9.2
-- The CXX compiler identification is GNU 4.9.2

After running `cmake`, you need to run `make`.
This will generate `imgui.so` on Linux/Mac, and `imgui.dll` on Windows.
On Linux, place imgui.so in

Code: Select all

~/.local/share/love

On Windows, place imgui.dll in Program Files/LOVE
Not sure about Mac.

Thanks, that works a treat. This lib is great, love it!

Hi all,


Looking for a GUI to use with LÖVE2D, what's current status on this one ? Thanks in advance !

Hi all,

Well I would say that it works quite well and it's pretty stable and functional now. But be aware that it's a GUI mostly intended for tools/editors creation, not really for in-game elements. You can still tweak it for this purpose but it's clearly not its best usage.

And the biggest issue is still the lack of documentation, the best way to work with it is to have the imgui.h file opened and use it as your reference.

Hi Fenrir,


OK, thanks for the hints, I'll see to it, one of the things I wanna do is write a stellar systems editor, so it fits ^-^ If it's OK for making the game also, then I'll use it, alse I'll search for another GUI...

Does anyone know how to capture the button press against the 'X' (i.e. to close the window)? I've been looking into the docs and see that p_open is the second parameter in imgui.Begin() but it when i click it in my code it doesn't seem to have any effect/change the boolean value.

This is in the one place in my code where I use this feature

Code: Select all

local isVisible, isOpen = imgui.Begin(windowID, true, flags)
if isOpen == false then
    -- don't run this block next time
end
imgui.End()

afaik this is an automatically generated change. The C++ api uses that second argument as a reference parameter, but those don't exist in lua so they get tacked on to the list of return arguments instead. This also applies to things like the text fields iirc.
