How are custom fonts loaded?

[RadenTheFolf]

I'm using the Steam ultra app kit. I created a new project using the project manager and am trying to get font loading to work. I'm not sure if the feature just isn't available on the steam version or if I am missing something.

 

#include "UltraEngine.h"
#include "LoadingWindow.h"



LoadingWindow::LoadingWindow(const char* steamName)
{
		SteamName = steamName;
}

void LoadingWindow::Create()
{
    //Get the displays
    std::vector<std::shared_ptr<UltraEngine::Display>> displays = UltraEngine::GetDisplays();

    //Create window
    Window = CreateWindow("Ultra Engine", 0, 0, 1000, 600, displays[0], UltraEngine::WINDOW_CENTER);
    //Create user interface
    std::shared_ptr<UltraEngine::Interface> ui = UltraEngine::CreateInterface(Window);
    WindowHandel = Window->GetHandle();

    //Create a pixmap
    std::shared_ptr<UltraEngine::Icon> icon = UltraEngine::LoadIcon("Resources/Images/splashbg.svg");
    Icon = icon->Rasterize(2.0);

    // load custom fonts
    auto font = UltraEngine::LoadFont("Resources/Fonts/Inter-Black.ttf");

    UltraEngine::iVec2 sz = ui->root->GetSize();
    std::shared_ptr<UltraEngine::Widget> label1 = CreateLabel("Version: 2023.4.22", 500, 160, 240, 60, ui->root);
    label1->SetFontScale(1.5);
    label1->SetFontBold(true);
    std::shared_ptr<UltraEngine::Widget> lable2 = CreateLabel("Welcome back " + std::string(SteamName) + "!", 500, 210, 300, 60, ui->root);
    lable2->SetFontScale(1.75);
    lable2->SetFontBold(true);
    std::shared_ptr<UltraEngine::Widget> widget = CreateProgressBar(500, 250, 400, 10, ui->root);
    widget->SetProgress(0.0);
    std::shared_ptr<UltraEngine::Widget> label3 = CreateLabel("Loading...", 500, 270, 300, 60, ui->root);

	ProgressTimer = UltraEngine::CreateTimer(500);
    ListenEvent(UltraEngine::EVENT_TIMERTICK, ProgressTimer, UpdateProgress, widget);


    //Show the icon
    ui->root->SetPixmap(Icon);
}


void LoadingWindow::Close()
{
    Window->Close();
}



bool LoadingWindow::UpdateProgress(const UltraEngine::Event& e, std::shared_ptr<UltraEngine::Object> extra)
{
    std::shared_ptr<UltraEngine::Widget> widget = extra->As<UltraEngine::Widget>();
    widget->SetProgress(UltraEngine::Mod(float(e.data) / 20.0f, 1.0f));
    return true;
}

I tried following the example in the documentation but am getting this error no matter how I've tried to load a font.

Am I missing something?

Custom fonts on Windowed interfaces are currently not supported, but you can adjust the text scale and weight on a per-widget basis,and it will be scaled relatively for different DPI settings. On windowed interfaces, the GUI will use the default system font.

LoadFont is for use with 3D GUIs and sprites, and is only available in Ultra Engine:
