Overview

imgui-notify

Is a header-only wrapper made to create notifications with Dear ImGui. As I couldn't find any library for this I just decided to create my own. We will use Font Awesome 5 for icons.

Usage

#include "notify.h"

// Initialisation, once at the beggining of your code, usually after ImGui_ImplDX12_Init()
notify::init();

// Add a new toast
if (ImGui::Button("success!"))
{
    notify::insert({ toast_type::toast_type_success, 3000, "Hello World! This is a success! %s", "We can also format here:)" });
}

if (ImGui::Button("warning!"))
{
    notify::insert({ toast_type::toast_type_warning, 3000, "Hello World! This is a warning!" });
}

if (ImGui::Button("error!"))
{
    notify::insert({ toast_type::toast_type_error, 3000, "Hello World! This is an error!" });
}

if (ImGui::Button("info!"))
{
    notify::insert({ toast_type::toast_type_info, 3000, "Hello World! This is an info!" });
}

if (ImGui::Button("info!"))
{
    notify::insert({ toast_type::toast_type_info, 3000, "Hello World! This is an info! Yes I also support multiline text! Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation" });
}

// Render toasts, at the end of your rendering
notify::render();

Add a fade in and out movement...

NOTIFY_FORMAT doesn't compile

i.e.

imgui_notify.h:205:83: error: expected expression
    ImGuiToast(ImGuiToastType type, const char* format, ...) : ImGuiToast(type) { NOTIFY_FORMAT(this->set_content, format); }

imgui_notify.h:23:120: note: expanded from macro 'NOTIFY_FORMAT'
#define NOTIFY_FORMAT(fn, format, ...)  if (format) { va_list args; va_start(args, format); fn(format, args, __VA_ARGS__); va_end(args); }

That's what my clangd 14.0.0 says

Clangd config: -Wno-unused-variable,-Wno-infinite-recursion,-Werror=implicit-function-declaration,-Wshadow,-Wno-shadow-field-in-constructor-modified,-Wno-shadow-ivar,-Wuninitialized,-Wunused-label,-Wunused-lambda-capture, ,--target=aarch64

GetMainViewport not defined

GetMainViewport seems to be undefined, couldn't figure out why. Could it be an issue with my ImGUI version? I'm using v1.69.

const auto vp_size = GetMainViewport()->Size;

sprintf_s in code
line about 260-270

char window_name[50]; sprintf_s(window_name, "##TOAST%d", i);

I'd suggest to replace it with ImFormat cuz not everyone has sprintf_s function

Icons aren't working

Hey, I followed your instructions and everything works fine except the Icons. I tried it with different fonts, but instead of an Icon it shows a colored Question mark "?". The font applys tho as the text changes the font style based on the Font that I use.

I use the following code after the Init:

writefont = io.Fonts->AddFontFromMemoryCompressedTTF(Font_Font_data, Font_Font_size, 16.f); ImFontConfig font_cfg; font_cfg.FontDataOwnedByAtlas = false; io.Fonts->AddFontFromMemoryCompressedTTF(Font_Font_data, Font_Font_size, 16.f, &font_cfg); ImGui::MergeIconsWithLatestFont(16.f, false);

To use the font I do:

ImGui::PushFont(writefont); //apply font ImGui::PushStyleVar(ImGuiStyleVar_WindowRounding, 5.f); ImGui::PushStyleColor(ImGuiCol_WindowBg, ImVec4(43.f / 255.f, 43.f / 255.f, 43.f / 255.f, 255.f / 255.f)); ImGui::RenderNotifications(); ImGui::PopStyleVar(1); ImGui::PopStyleColor(1); ImGui::PopFont();
