ahmed605 / imgui-uwp

this is the error i get, can you please help me <3

which ImGui version are you using? ImGui-UWP was only tested on v1.90+
also what are the C++ & Windows SDK versions used? ImGui-UWP was only tested on C++ 17 with Windows 11 22000+ SDK

also make sure you included ImGui headers in this order: imgui.h, imgui_impl_uwp.h, and the graphics backend header of choice, so like this for example:

#include <imgui.h>
#include <imgui_impl_uwp.h>
#include <imgui_impl_dx12.h>

ok, i got everything narrowed down to just these issues.

i tried using GPT but it was no help

im using imgui 1.95, C++ 20, release x64

ive also tried to set them to values but nothing worked

ok, i got everything narrowed down to just these issues.

i tried using GPT but it was no help

Seems like you aren't using a standard UWP project, can you check if linking WindowsApp.lib fixes it?

i will try right now

IT FIXED IT!!! THANK YOU SO MUCH

Also, how can i hook keyboard inputs? i managed to do mouse inputs but not keyboard

the backend should already support keyboard input, I have tried it with built-in ImGui text input controls and it was working

i cant type still, is there something i need to add into my main code for it to work? currently i have only included the backends

Can you show me how do you initialize the backend?

thats what im having trouble with, im very new to imgui

this is my main thread

this is my current render init

oh this is how the backend should be initialized

ill give it a shot, thanks!

do you have discord by any chance?

yes, @ahmedwalid

I get tons of errors, i need a little bit of help, all errors are in the backends cpp file
